| Research Abstract |
In delivery planning problems, there is often a hierarchical structure between an owner of goods and a delivery company who mutually have a cooperative relationship and different several objective functions which are usually conflict with each other. In this research, I have formulated a hierarchical multi-objective delivery planning problem as a bi-level multi-objective programming problem where decision variables are delivery route and the position of a delivery center. Furthermore, I have developed an algorithm for obtaining a satisfaction solution for not only the owner of goods but also the delivery company, in which the satisfaction solution takes account of the ambiguity contained in the knowledge of experts as well as the randomness related to stochastic factors such as customer demand.
