A propositon of benchmark selection index of production control system using multiple evaluation items

The purpose of this paper is to suggest a benchmark selection index of production control system based on multiple evaluation items. One of the characteristics of benchmarking which is widely used in recent year is to improve procedure by analyzing best business process which is so called 'best practice'. In the benchmark selection process, the weighted sum of multiple evaluations is widely used for benchmark selection index. Yet, generally speaking, the weighted sum assumes that a decision maker accepts trade-off between multiple items. Therefore, there are many cases that the system which has excellent performance in an unimportant item is selected. As a result, it may tend to cause problematic outcomes in benchmarking selection because improvement procedure in benchmarking tends to keep the performance of selected system. In order to avoid these kinds of problems, this paper proposes the benchmark index of production control system which consists of three; 1) direction index; 2) balance index; and 3) improvement index.
