Calculating Procedure of Cost Factors in Sample-Size Determination : On the Determination of Sample-Size Considering Cost Factors in Work Measurement(III)

Abstract

In the previous papers, methods were proposed for determining a sample-size to minimize the expected costs for single-operator and multi-operator production systems. This paper gives a computational procedure for calculating the cost factors to show the applicabillity of proposed methods. The numerical examples of the cost factors production system design(c_1,c_2), production system operation(c_3,c_4)and work measurement (c_5) are investigated in practical factories, then a basis for the determination of sample-size is provided.
