Batch Size Determination: A Case Study of Hard Disk Drive Industry

Abstract:

This paper gives an attempt in determining an appropriate production batch size by using simulation method. The case study of this paper is an industry producing hard disk drives in Thailand. The scope of the production process considered in this paper is in the backend area of the production process of hard disk drives. Three main customers are considered. Each customer requires different sample size in an inspection process and the sample size affects bath size. Therefore, this paper needs to consider each customer separately and tries to determine an appropriate batch size for each customer. First, data collection of the process and its details are given. The as-is simulation model is constructed. Outputs, production lead time, work in process and machine utilization are used to verified the as-is model. The statistical method is used to compare between those in the real system and those based on the model. Further three levels of batch sizes are analyzed by using the simulation model. It is found that each customer type requires different batch size.
