Planning system, planning method and program

PROBLEM TO BE SOLVED: To make a robust distribution plan for uncertainties of a response method for a distribution plan in which a product is collected / disassembled and the product is assembled and returned again using parts maintained by an appropriate response method. Provide a planning system to create. A planning system calculates an evaluation value of a distribution plan and a planning unit that delivers a product to be maintained from a use base, disassembles, maintains, and assembles the product, and creates a distribution plan to be delivered to the use base. It includes an evaluation unit, a selection unit that selects the distribution plan based on the evaluation value, and a control unit that instructs the creation of the distribution plan. A plan is created, and the evaluation unit calculates the first evaluation value of the distribution plan created for each combination of the corresponding methods, multiplies the occurrence probability of the corresponding method, and calculates the second evaluation value, and all the corresponding methods. The second evaluation value is totaled to calculate the third evaluation value, and the selection unit selects the distribution plan based on the third evaluation value. [Selection diagram] Fig. 1
