The target costing technique, mathematically discussed by Sauers, only uses the p C index along with Taguchi loss function and X -R control charts to setup goal control limits. The new specification limits derived from Taguchi loss function is linked through the p C value to X -R control charts to obtain goal control limits. In this study, the target costing technique is exploited by further co...

In recent years, determining the best supplier has become a key strategic consideration in the competitive market. Since the decision commonly involves evaluating different criteria or attributes, supplier selection process is a multiple criteria decision-making (MCDM) problem. This study integrates the Taguchi loss function, analytical hierarchy process (AHP) and multi-choice goal programming ...

Methods of designing equipment to improve quality have been developed by Taguchi. A key feature of these methods is the development of loss function, which quantifies the financial cost (loss) resulting from deviations from target dimensions. Total knee arthroplasties can fail due to prosthetic component malalignment. A Taguchi loss function for varus/valgus alignment of the prosthesis and revi...

Process of purchase or supply is one of the most important factors of competitiveness of companies. Therefore, the supply managers of companies are expected to select and evaluate the suppliers, to provide the company needs. Evaluation of suppliers based on only one factor is not possible and it is necessary to adopt a method that several factors simultaneously be evaluated. Suppliers can be ev...

this paper presents a new approach which is based on quality control in order to optimize supplier selection. using inspections, removing the defected materials and considering penalties for low quality materials are the main factors which we have considered in modeling. in this model costs are divided to three parts: 1- costs of purchasing 2- costs of inspection policy 3- costs of quality and ...

Along with the widespread use of Taguchi methods in product design, deenition of the loss function has been integrated with numerous models which require quality cost estimation. In this paper, the economic-statistical design of a variable sampling X-bar control chart is extended using the Taguchi loss function to improve chart eeectiveness from a quality cost point of view. The eeectiveness of...

With the growing commercialization of watermarking techniques in various application scenarios it has become increasingly important to quantify the performance of watermarking products. The quantification of relative merits of various products is not only essential in enabling further adoption of the technology by society as a whole, but will also drive the industry to develop testing plans/met...

The classical Taguchi quality model only considers the control of quality. Huang[9] proposed a model that took both quality and cost into account. Huang’s model presents a trade-off problem between quality and cost, in which higher quality is not the final aim but the profit. In Huang’s model, the symmetrical quadratic quality loss function was employed to stand for the loss of profit. In this ...

Loss functions play a fundamental role in every quality engineering method. A new set of loss functions is proposed based on Taguchi’s societal loss concept. Its applications to robust parameter design are discussed in detail. The loss functions are shown to posses some interesting properties and lead to theoretical results that cannot be handled with other loss functions.
