Stepwise Evaluation Method Based on Multi-Criteria Analysis

Abstract Recently, the scale of projects is increasing and it has become ncceesary to cope with multiple objectives and their various impacts. Consequently, it is sometimes difficult to clarify the preference relation among projects. In this paper we propose a stepwise evaluation method, which examines the preference relation among projects step by step. This method involves the MODICA model, which is an evaluation model we developed to evaluate projects without many hypotheses and complex analyses. This stepwi-se evaluation method is useful particularly when the number of projects is large. An example of calculation explains the stepwise evaluation process of this method.
