<p>PURPOSE:To provide a production planning device which can maximize the total productivity of a production line within a range of capability of facilitates and also can satisfy the time limit of the delivery of the order. CONSTITUTION:A production planning device 0 consists of a calculating part 2 which calculates the lead time covering the neck process through the final process for each order and subtracts the lead time from the time limit of delivery set to the ordering to decide a schedules starting date of the neck process, an initial lot composing part 3 which gathers the orders received in a prescribed period of the neck process for each specification and initially composes a lot, a neck process load plan producing part 4 which continuously fetches the orders of the subsequent scheduled starting dates of the neck process into the lot to produce a load plan of the neck process, a total load plan producing part 6 which performs the FF/FB piling by means of the load plan and based on the neck process scheduled starting date within a range that satisfies the time limit of delivery to the order, etc. In such a constitution, the total productivity of a production line is maximized within a range of capability of facilities. Furthermore a production plan is obtained to satisfy the time limit of delivery to the order.</p> |
