Comparative Study on Parameter Design of Quality Control Modeling in Supply Chain

Abstract:

The quality control model was constructed and solved in supply chain with continuous quality parameters by improving the existing quality control model in supply chain of discrete quality parameters to solve the uncertain problems in quality control of supply chain. Moreover, a comparative study was made of the modeling assumptions, modeling process and case calculation in quality control model of supply chain under continuous and discrete quality parameters. The results show that the quality control decisions of supply chain with continuous quality parameters can reflect the practical situation more accurately than the quality control decisions of supply chain with discrete quality parameters; in addition, the uncertainty of quality control in supply chain is decreased by the quality control model of supply chain with continuous quality parameters; moreover, the changes tendency of the quality prevention level and quality inspection level along with the change of corresponding inputs are approximate in accordance with exponential distribution, and this situation would provide support and basis for the decisions of manufacturer’s optimal quality prevention inputs and retailer’s optimal quality inspection inputs.
