Inspection Allocation Problem at Multi-stage Manufacturing System

Abstract

The quality of products in different manufacturing systems has received extensive studying and attention. The aim of this study is how to reach the required quality level on the way to meet customer requirements by using available resources. Nowadays, in the highly competitive market, many organizations realized that their survival in the market depends mainly on producing high quality products and services. Applying a proper quality plan in industries is vital to cope with competitive markets and services. The aim of the present research is to introduce a new model for optimizing inspection allocation problem (IAP) at different multistage manufacturing systems and to study all the factors that affect the IAP using different performance total cost, line efficiency and smoothness index. Therefore, the objective here is to allocate an economical number of inspection stations, which accomplish a certain level of quality and generate the correct balance among different cost components. Many researches have studied during the past decade to enhance the quality inspection system and many mathematical models have been applied to industrial systems to improve their efficiency and productivity.
