Multi-Objective Planning Method for Flexible Adjustment to the Aspiration Levels of Water Supply System Designers

We propose a hybrid method using interactive multi-criteria programming and minimum cost flow optimization to make a useful schedule for waterworks. In case of constructing a mathematical model, it is difficult to adjust the method parameters in the actual application, and to make the user satisfied with the solution under the predetermined parameters. In our research, the parameters are generated automatically based on the abstract planning, in which interactive multi-criteria programming is employed, and then the minimum cost flow is calculated under the generated parameters. As a result, the proposed method can make an applicable quickly, reflecting the user’s aspiration flexibly
