Sample Size for Minimizing Cost in Multi-Operator Production System : On the Determination of Sample Size Considering Cost Factors in Work Measurement (II)

Abstract

This paper studise the sample size determination for time study in Multi-Operator Production System. In this type of Production System, the results of time study for one selected operator apply to the others, after being processed through prevailing rating system. Under these conditions, a method of sample size determenation is presented, which minimizes the total of losses caused by both improper production system desing and operation and cost of work measurement, each depending on the size of sample.
