Title: PRODUCTION PLAN CREATION DEVICE, PRODUCTION PLAN CREATION METHOD, AND PRODUCTION PLAN CREATION PROGRAM
Abstract:
Provided is a production plan creation device in which a planning unit uses history information relating to production plans for individual products planned in the past as a basis to calculate a plan pattern including a production order for each of the products while taking into account each of restricting conditions on the occasion of production of each of the products, then creates a plurality of plan candidates relating to production plans for each of the products in which the production order of each of the products is rearranged in accordance with the calculated plan pattern. A plan evaluation unit evaluates the plurality of plan candidates on the basis of an evaluation index for each of the restricting conditions and selects an optimal production plan from among the plurality of plan candidates.
