Comparison for the total expected quality control cost between proposed model and Schmidt-Taylor model

Abstract

In this paper ,we constructed a model for the total expected cost of quality control, which include four components, A1(inspection cost) and A2 represent cost of accepting defective units ,and the third component is A3(cost of rejecting good units) and finally A4 which is the loss due to stopping of production line. This model is modification for the model presented by Schmidt-Taylor [2]. The aim of model is to determine the three parameters of single sampling plan, were is the sample size, is acceptance number and is the time interval between inspections. The proposed model needs the multivariate search technique and enumeration procedure; to solve the expected cost quality model and then obtain the set of parameters that minimize this function the efficiency of proposed model was compared with this due to Schmidt-Taylor model .All notations and derivations are explained.Keyword: Acceptance sampling plan, proposed model for expected total cost of quality control, Multivariate search technique, enumeration procedure application.
