The Taguchi Methods for Quality Improvement

INTRODUCTION: Taguchi methods are statistical methods developed by Genichi Taguchi to improve the quality of manufactured goods, and more recently also applied to, engineering, biotechnology, marketing and advertising. Professional statisticians have welcomed the goals and improvements brought about by Taguchi methods, particularly by Taguchi’s development of designs for studying variation, but have criticized the inefficiency of some of Taguchi’s proposals. Taguchi’s work includes three principal contributions to statistics: A specific loss function – see Taguchi loss function; The philosophy of off-line quality control; and Innovations in the design of experiments. Loss functions Loss functions in statistical theory Traditionally, statistical methods have relied on mean-unbiased estimators of treatment effects: Under the conditions of the Gauss-Markov theorem, least squares estimators have minimum variance among all mean-unbiased estimators. The emphasis on comparisons of means also draws (limiting) comfort from the law of large numbers, according to which the sample means converge to the true mean. Fisher’s textbook on the design of experiments emphasized comparisons of treatment means. Gauss proved that the sample-mean minimizes the expected squared-error loss-function (while Laplace proved that a median-unbiased estimator minimizes the absolute-error loss function). In statistical theory, the central role of the loss function was renewed by the statistical decision theory of Abraham Wald. However, loss functions were avoided by Ronald A. Fisher.[6] Taguchi’s use of loss functions Taguchi knew statistical theory mainly from the followers of Ronald A. Fisher, who also avoided loss functions. Reacting to Fisher’s methods in the design of experiments, Taguchi interpreted Fisher’s methods as being adapted for seeking to improve the mean outcome of a process. Indeed, Fisher’s work had been largely motivated by programmes to compare agricultural yields under different treatments and blocks, and such experiments were done as part of a long-term programme to improve harvests. However, Taguchi realised that in much industrial production, there is a need to produce an outcome on target, for example, to machine a hole to a specified diameter, or to manufacture a cell to produce a given voltage. He also realised, as had Walter A. Shewhart and others before him, that excessive variation lay at the root of poor manufactured quality and that reacting to individual items inside and outside specification was counterproductive. He therefore argued that quality engineering should start with an understanding of quality costs in various situations. In much conventional industrial engineering, the quality costs are simply represented by the number of items outside specification multiplied by the cost of rework or scrap. However, Taguchi insisted that manufacturers broaden their horizons to consider cost to society. Though the short-term costs may simply be those of non-conformance, any item manufactured away from nominal would result in some loss to the customer or the wider community through early wear-out; difficulties in interfacing with other parts, themselves probably wide of nominal; or the need to build in safety margins. These losses are externalities and are usually ignored by manufacturers, which are more interested in their private costs than social costs. Such externalities prevent markets from operating efficiently, according to analyses of public economics. Taguchi argued that such losses would inevitably find their way back to the originating corporation (in an effect similar to the tragedy of the commons), and that by working to minimise them, manufacturers would enhance brand reputation, win markets and generate profits. Such losses are, of course, very small when an item is near to negligible. Donald J. Wheeler characterised the region within specification limits as where we deny that losses exist. As we diverge from nominal, losses grow until the point where losses are too great to deny and the specification limit is drawn. All these losses are, as W. Edwards Deming would describe them, unknown and unknowable, but Taguchi wanted to find a useful way of representing them statistically. Taguchi specified three situations: Larger the better (for example, agricultural yield); Smaller the better (for example, carbon dioxide emissions); and On-target, minimum-variation (for example, a mating part in an assembly). The first two cases are represented by simple monotonic loss functions. In the third case, Taguchi adopted a squared-error loss function for several reasons: It is the first “symmetric” term in the Taylor series expansion of real analytic loss-functions. Total loss is measured by the variance. As variance is additive (for uncorrelated random variables), the total loss is an additive measurement of cost (for uncorrelated random variables). The squared-error loss function is widely used in statistics, following Gauss’s use of the squared-error loss function in justifying the method of least squares. Reception of Taguchi’s ideas by statisticians Though many of Taguchi’s concerns and conclusions are welcomed by statisticians and economists, some ideas have been especially criticized. For example, Taguchi’s recommendation that industrial experiments maximise some signal-to-noise ratio (representing the magnitude of the mean of a process compared to its variation) has been criticized widely. Off-line quality control Taguchi’s rule for manufacturing Taguchi realized that the best opportunity to eliminate variation is during the design of a product and its manufacturing process. Consequently, he developed a strategy for quality engineering that can be used in both contexts. The process has three stages: System design Parameter design Tolerance design System design This is design at the conceptual level, involving creativity and innovation. Parameter design Once the concept is established, the nominal values of the various dimensions and design parameters need to be set, the detail design phase of conventional engineering. Taguchi’s radical insight was that the exact choice of values required is under-specified by the performance requirements of the system. In many circumstances, this allows the parameters to be chosen so as to minimise the effects on performance arising from variation in manufacture, environment and cumulative damage. This is sometimes called robustification. Tolerance design With a successfully completed parameter design, and an understanding of the effect that the various parameters have on performance, resources can be focused on reducing and controlling variation in the critical few dimensions (see Pareto principle). Design of experiments Taguchi developed his experimental theories independently. Taguchi read works following R. A. Fisher only in 1954. Taguchi’s framework for design of experiments is idiosyncratic and often flawed, but contains much that is of enormous value. He made a number of innovations. Outer arrays Taguchi’s designs aimed to allow greater understanding of variation than did many of the traditional designs from the analysis of variance (following Fisher). Taguchi contended that conventional sampling is inadequate here as there is no way of obtaining a random sample of future conditions.[7] In Fisher’s design of experiments and analysis of variance, experiments aim to reduce the influence of nuisance factors to allow comparisons of the mean treatment-effects. Variation becomes even more central in Taguchi’s thinking. Taguchi proposed extending each experiment with an “outer array” (possibly an orthogonal array); the “outer array” should simulate the random environment in which the product would function. This is an example of judgmental sampling. Many quality specialists have been using “outer arrays”. Later innovations in outer arrays resulted in “compounded noise.” This involves combining a few noise factors to create two levels in the outer array: First, noise factors that drive output lower, and second, noise factors that drive output higher. “Compounded noise” simulates the extremes of noise variation but uses fewer experimental runs than would previous Taguchi designs. Management of interactions Interactions, as treated by Taguchi Many of the orthogonal arrays that Taguchi has advocated are saturated arrays, allowing no scope for estimation of interactions. This is a continuing topic of controversy. However, this is only true for “control factors” or factors in the “inner array”. By combining an inner array of control factors with an outer array of “noise factors”, Taguchi’s approach provides “full information” on control-by-noise interactions, it is claimed. Taguchi argues that such interactions have the greatest importance in achieving a design that is robust to noise factor variation. The Taguchi approach provides more complete interaction information than typical fractional factorial designs, its adherents claim. * Followers of Taguchi argue that the designs offer rapid results and that interactions can be eliminated by proper choice of quality characteristics. That notwithstanding, a “confirmation experiment” offers protection against any residual interactions. If the quality characteristic represents the energy transformation of the system, then the “likelihood” of control factor-by-control factor interactions is greatly reduced, since “energy” is “additive”. Inefficencies of Taguchi’s designs * Interactions are part of the real world. In Taguchi’s arrays, interactions are confounded and difficult to resolve. Statisticians in response surface methodology (RSM) advocate the “sequential assembly” of designs: In the RSM approach, a screening design is followed by a “follow-up design” that resolves only the confounded interactions that are judged to merit resolution. A second follow-up design may be added, time and resources allowing, to explore possible high-order univariate effects of the remaining variables, as high-order univariate effects are less likely in variables already eliminated for having no linear effect. With the economy of screening designs and the flexibility of follow-up designs, sequential designs have great statistical efficiency. The sequential designs of response surface methodology require far fewer experimental runs than would a sequence of Taguchi’s designs.[ TAGUCHI METHODS There has been a great deal of controversy about Genichi Taguchi’s methodology since it was first introduced in the United States. This controversy has lessened considerably in recent years due to modifications and extensions of his methodology. The main controversy, however, is still about Taguchi’s statistical methods, not about his philosophical concepts concerning quality or robust design. Furthermore, it is generally accepted that Taguchi’s philosophy has promoted, on a worldwide scale, the design of experiments for quality improvement upstream, or at the product and process design stage. Taguchi’s philosophy and methods support, and are consistent with, the Japanese quality control approach that asserts that higher quality generally results in lower cost. This is in contrast to the widely prevailing view in the United States that asserts that quality improvement is associated with higher cost. Furthermore, Taguchi’s philosophy and methods support the Japanese approach to move quality improvement upstream. Taguchi’s methods help design engineers build quality into products and processes. As George Box, Soren Bisgaard, and Conrad Fung observed: “Today the ultimate goal of quality improvement is to design quality into every product and process and to follow up at every stage from design to final manufacture and sale. An important element is the extensive and innovative use of statistically designed experiments.” TAGUCHI’S DEFINITION OF QUALITY The old traditional definition of quality states quality is conformance to specifications. This definition was expanded by Joseph M. Juran (1904-) in 1974 and then by the American Society for Quality Control (ASQC) in 1983. Juran observed that “quality is fitness for use.” The ASQC defined quality as” the totality of features and characteristics of a product or service that bear on its ability to satisfy given needs.” Taguchi presented another definition of quality. His definition stressed the losses associated with a product. Taguchi stated that “quality is the loss a product causes to society after being shipped, other than losses caused by its intrinsic functions.” Taguchi asserted that losses in his definition “should be restricted to two categories: (1) loss caused by variability of function, and (2) loss caused by harmful side effects.” Taguchi is saying that a product or service has good quality if it “performs its intended functions without variability, and causes little loss through harmful side effects, including the cost of using it.” It must be kept in mind here that “society” includes both the manufacturer and the customer. Loss associated with function variability includes, for example, energy and time (problem fixing), and money (replacement cost of parts). Losses associated with harmful side effects could be market shares for the manufacturer and/or the physical effects, such as of the drug thalidomide, for the consumer. Consequently, a company should provide products and services such that possible losses to society are minimized, or, “the purpose of quality improvement … is to discover innovative ways of designing products and processes that will save society more than they cost in the long run.” The concept of reliability is appropriate here. The next section will clearly show that Taguchi’s loss function yields an operational definition of the term “loss to society” in his definition of quality. TAGUCHI’S LOSS FUNCTION We have seen that Taguchi’s quality philosophy strongly emphasizes losses or costs. W. H. Moore asserted that this is an “enlightened approach” that embodies “three important premises: for every product quality characteristic there is a target value which results in the smallest loss; deviations from target value always results in increased loss to society; [and] loss should be measured in monetary units (dollars, pesos, francs, etc.).” Figure I depicts Taguchi’s typically loss function. The figure also contrasts Taguchi’s function with the traditional view that states there are no losses if specifications are met. Taguchi’s Loss Function It can be seen that small deviations from the target value result in small losses. These losses, however, increase in a nonlinear fashion as deviations from the target value increase. The function shown above is a simple quadratic equation that compares the measured value of a unit of output Y to the target T.: Essentially, this equation states that the loss is proportional to the square of the deviation of the measured value, Y, from the target value, T. This implies that any deviation from the target (based on customers’ desires and needs) will diminish customer satisfaction. This is in contrast to the traditional definition of quality that states that quality is conformance to specifications. It should be recognized that the constant k can be determined if the value of L(Y) associated with some Y value are both known. Of course, under many circumstances a quadratic function is only an approximation. Since Taguchi’s loss function is presented in monetary terms, it provides a common language for all the departments or components within a company. Finally, the loss function can be used to define performance measures of a quality characteristic of a product or service. This property of Taguchi’s loss function will be taken up in the next section. But to anticipate the discussion of this property, Taguchi’s quadratic function can be converted to: This can be accomplished by assuming Y has some probability distribution with mean, a and variance o.2 This second mathematical expression states that average or expected loss is due either to process variation or to being off target (called “bias”), or both. TAGUCHI, ROBUST DESIGN, AND THE DESIGN OF EXPERIMENTS Taguchi asserted that the development of his methods of experimental design started in Japan about 1948. These methods were then refined over the next several decades. They were introduced in the United States around 1980. Although, Taguchi’s approach was built on traditional concepts of design of experiments (DOE), such as factorial and fractional factorial designs and orthogonal arrays, he created and promoted some new DOE techniques such as signal-to-noise ratios, robust designs, and parameter and tolerance designs. Some experts in the field have shown that some of these techniques, especially signal-to-noise ratios, are not optimal under certain conditions. Nonetheless, Taguchi’s ideas concerning robust design and the design of experiments will now be discussed. DOE is a body of statistical techniques for the effective and efficient collection of data for a number of purposes. Two significant ones are the investigation of research hypotheses and the accurate determination of the relative effects of the many different factors that influence the quality of a product or process. DOE can be employed in both the product design phase and production phase. A crucial component of quality is a product’s ability to perform its tasks under a variety of conditions. Furthermore, the operating environmental conditions are usually beyond the control of the product designers, and, therefore robust designs are essential. Robust designs are based on the use of DOE techniques for finding product parameter settings (e.g., temperature settings or drill speeds), which enable products to be resilient to changes and variations in working environments. It is generally recognized that Taguchi deserves much of the credit for introducing the statistical study of robust design. We have seen how Taguchi’s loss function sets variation reduction as a primary goal for quality improvement. Taguchi’s DOE techniques employ the loss function concept to investigate both product parameters and key environmental factors. His DOE techniques are part of his philosophy of achieving economical quality design. To achieve economical product quality design, Taguchi proposed three phases: system design, parameter design, and tolerance design. In the first phase, system design, design engineers use their practical experience, along with scientific and engineering principles, to create a viably functional design. To elaborate, system design uses current technology, processes, materials, and engineering methods to define and construct a new “system.” The system can be a new product or process, or an improved modification of an existing product or process. The parameter design phase determines the optimal settings for the product or process parameters. These parameters have been identified during the system design phase. DOE methods are applied here to determine the optimal parameter settings. Taguchi constructed a limited number of experimental designs, from which U.S. engineers have found it easy to select and apply in their manufacturing environments. The goal of the parameter design is to design a robust product or process, which, as a result of minimizing performance variation, minimizes manufacturing and product lifetime costs. Robust design means that the performance of the product or process is insensitive to noise factors such as variation in environmental conditions, machine wear, or product to-product variation due to raw material differences. Taguchi’s DOE parameter design techniques are used to determine which controllable factors and which noise factors are the significant variables. The aim is to set the controllable factors at those levels that will result in a product or process being robust with respect to the noise factors. In our previous discussion of Taguchi’s loss function, two equations were discussed. It was observed that the second equation could be used to establish quality performance measures that permit the optimization of a given product’s quality characteristic. In improving quality, both the average response of a quality and its variation are important. The second equation suggests that it may be advantageous to combine both the average response and variation into a single measure. And Taguchi did this with his signal-to-noise ratios (S/N). Consequently, Taguchi’s approach is to select design parameter levels that will maximize the appropriate S/N ratio. These S/N ratios can be used to get closer to a given target value (such as tensile strength or baked tile dimensions), or to reduce variation in the product’s quality characteristic(s). For example, one S/N ratio corresponds to what Taguchi called “nominal is best.” Such a ratio is selected when a specific target value, such as tensile strength, is the design goal. For the “nominal is best” case, Taguchi recommended finding an adjustment factor (some parameter setting) that will eliminate the bias discussed in the second equation. Sometimes a factor can be found that will control the average response without affecting the variance. If this is the case, our second equation tells us that the expected loss becomes: Consequently, the aim now is to reduce the variation. Therefore, Taguchi’s S/N ratio is: where S 2 is the sample’s standard deviation. In this formula, by minimizing S 2 , – 10 log 10 S 2 , is maximized. Recall that all of Taguchi’s S/N ratios are to be maximized. Finally, a few brief comments concerning the tolerance design phase. This phase establishes tolerances, or specification limits, for either the product or process parameters that have been identified as critical during the second phase, the parameter design phase. The goal here is to establish tolerances wide enough to reduce manufacturing costs, while at the same time assuring that the product or process characteristics are within certain bounds. EXAMPLES AND CONCLUSIONS As Thomas P. Ryan has stated, Taguchi at the very least, has focused “our attention on new objectives in achieving quality improvement. The statistical tools for accomplishing these objectives will likely continue to be developed.” Quality management “gurus,” such as W. Edwards Deming (1900-1993) and Kaoru Ishikawa (1915-), have stressed the importance of continuous quality improvement by concentrating on processes upstream. This is a fundamental break with the traditional practice of relying on inspection downstream. Taguchi emphasized the importance of DOE in improving the quality of the engineering design of products and processes. As previously mentioned, however,” his methods are frequently statistically inefficient and cumbersome.” Nonetheless, Taguchi’s design of experiments have been widely applied and theoretically refined and extended. Two application cases and one refinement example will now be discussed. K. N. Anand, in an article in Quality Engineering, discussed a welding problem. Welding was performed to repair cracks and blown holes on the cast-iron housing of an assembled electrical machine. Customers wanted a defect-free quality weld, however the welding process had resulted in a fairly high percentage of welding defects. Management and welders identified five variables and two interactions that were considered the key factors in improving quality. A Taguchi orthogonal design was performed resulting in the identification of two highly significant interactions and a defect-free welding process. The second application, presented by M. W. Sonius and B. W. Tew in a Quality Engineering article, involved reducing stress components in the connection between a composite component and a metallic end fitting for a composite structure. Bonding, pinning, or riveting the fitting in place traditionally made the connections. Nine significant variables that could affect the performance of the entrapped fiber connections were identified and a Taguchi experimental design was performed. The experiment identified two of the nine factors and their respective optimal settings. Therefore, stress levels were significantly reduced. The theoretical refinement example involves Taguchi robust designs. We have seen where such a design can result in products and processes that are insensitive to noise factors. Using Taguchi’s quadratic loss function, however, may provide a poor approximation of true loss and suboptimal product or process quality. John F. Kros and Christina M. Mastrangelo established relationships between nonquadratic loss functions and Taguchi’s signal-to-noise ratios. Applying these relationships in an experimental design can change the recommended selection of the respective settings of the key parameters and result in smaller losses.

Political Message in Wall-E

Implicit Politics Surrounds Wall-E The Disney Pixar film, “Wall-E” provides a futuristic outlook on the possible outcome of human life and the earth in which they inhabit. Wall-E influences the audience to question if the government’s take on pollution and sustainability is in its’ best interest for the human population. Climate change is a real and relevant, and Wall-E as supporting evidence as a guide throughout this reading. With this lens, I will review and discuss the political take on the movie, analyze the issue revolving around the participatory politics in popular culture, while raising awareness about what steps the government has taken or lack thereof to protect and promote a sustainable earth. Wall-E was released in 2008 by Disney Pixar studios. Wall-E is a small robot who is nestled within a decaying waste collecting industry. As a result, his home is primarily settled among an overwhelming amount of towers of garbage covering once tall skyscrapers. The protagonist, Wall-E stands for Waste Allocation Load Lifter – Earth class. In the movie, it shows in the maybe not so distant future that mankind has left earth because of the towering litter of garbage, and pollution left behind by mankind. The culprit behind the rubbish left behind was the product of the antagonist Buy N’ Large, a corporation whose primary motive is to produce a profit regardless if it results in making the earth uninhabitable. When the earth inevitably reached this breaking point, humans escaped to outer space to carry out a comfortable life where their rapacious need for consumption has turned them into “blobs” who cannot stand or move on their own. As a result, Wall-E is left alone on earth to clean up after the humans who have polluted and littered the earth. Over the centuries, Wall-E eventually learns certain values of sudo “emotions” and a sense of attachment to this once forgotten planet. Wall- E longs for these moments he finds in old movies and items he finds fascinating. Wall-E brings these items back to his shed and collects these old earth artifacts. This movie musical ultimately inspires feelings of loneliness and romantic longing in Wall-E. Suddenly, an advanced robot named Eve emerges from a spaceship causing Wall-E to simultaneously be terrified and intrigued. Eve is sent from the space station where the humans are housed in order to look for any remaining signs of life on earth. If life is spotted, her duty is to report this back to her human superiors so they will know that Earth is once again habitable, and return to recolonize the planet their ancestors destroyed. The movie has left the audience to question how the culture of consumption could lead earth to a desolate state. The film is an exaggerated extension of society’s consumer-driven lifestyle and the effect it has on causing detrimental pollution on earth. Wall-E brings awareness to the audience that earth could potentially be destroyed by pollution and climate change and what it may look like as a result. This raises the question of our own capabilities of sustaining earth. Particularly questioning to what degree does the government take the issue of pollution and global warming seriously? The government implementing climate control initiatives is a complicated subject and situation.There are a variety of different variables to be considered in order for this change to come into effect. For example, what changes can humans realistically adjust to to create a long term change? Can human society work together as a unit instead of being divided among what countries they reside in? I came across an activist, a young activist might I add, by the name Greta Thurnburg. She is a young environmental activist who attended the United Nations Summit.She delivered a speech at the United Nations summit, a call to the government to take action on climate change. Thurnburg was trying to convince the government to take more action on reducing carbon emissions(Milman, 2019). The summit had intentions to encourage companies and countries drive to reducing the carbon footprint left behind by countries and their trash, or companies and their machines. The release of toxic fumes into the atmosphere is shaving our Ozone layer. As many attempt to initiate a call to action in regard to climate change and sustainability, governments continue to show no avail. The state our earth is in now reflects a similar movement to what occurred in Wall-E’s eventually resulting in a deserted earth. Many do not realize the constant indulging society partakes in can exponentially progress our environment to a replica of Wall-E’s home. A popular online The Guardian stated, “A new UN analysis has found that commitments to cut planet-warming gases must be at least tripled and increased by up to fivefold if the world is to meet the goals of the 2015 Paris agreement of holding the temperature rise to at most 2C above the pre-industrial era” (Milman, 2019). What policy and movements can governments possibly implement to truly make a difference for the earth? In the movie, the antagonist Buy N Large has bureaucratic power to make waves of influence to its consumer. When utilizing a “critical approach” in this case, coined by social theorist Karl Marx, it is argued that, “…the prevailing ideologies and cultural norms of any society serve to benefit its ruling class and perpetuate their power”(Grazian, 2017, p.60). It seems that the critical approach is based on the idea that power is not equally distributed, it is rather based on a traditional hierarchy (Reed). In correlation to Wall-E, we see that Buy N Large’s main motive is to provide all the necessities for human life through its robust production. They hold a powerful stance in the lives of their consumers and are able to do so through their prevailing market power. This can reflect a parallel in our own government with capitalism. A possible reason the government takes small steps to curb fossil fuels, may be because large private businesses control a significant amount of the market and would rather sustain their profit than contribute to sustaining the earth. For example, Amazon is one of the largest and most profitable online e-commerce corporations. Amazon’s convenience of having all one’s necessities delivered straight to their door encourages people to buy more due to the ease in its process. Such ease also comes along with consequences to the environment as it lacks mandatory initiatives to promote sustainability. The environmental cost produced is caused by several corporations this day in age, as shipping is brought directly to the comfort of millions of people’s homes rather than to one store. “Expedited shipping means your packages may not be as consolidated as they could be, leading to more cars and trucks required to deliver them, and an increase in packaging waste, which researchers have found is adding more congestion to our cities, pollutants to our air, and cardboard to our landfills” (Nguyen, 2018, para. 2). This proves that the critical approach to Wall-E is parallel to the message that, if we do not address the perpetuating power of influencing consumer-driven consumption aggressively it can lead to an earth like Wall-E’s. As we have reviewed some political background on climate change, and its relation to Wall-E’s political message, and I do recognize the government taking steps toward a more sustainable earth. However, I do not think the steps are significant enough to make any noticeable change. An aggressive attack on curbing fossil fuels is necessary, but we have yet to see our government make any significant changes in law and holding certain corporation accountable for their waste. Awareness is raised and I believe every political party understands the significance of controlling pollution and climate change, but are looking to line their own pockets first before saving the planet. Wall-E serves as a crucial message that the ongoing actions of society and their respective governments hold the power to both increasingly damage their earth or make drastic change for the benefit of all.
