Abstract:To solve the problems of route uncertainty, inaccuracy of work time, fast changes of the process and fast logistics in the status of discrete production process, a method is proposed that makes the value of production in plan period as the pursuit goals. The completion time node is not needed to be pursued in schedule but the production order. So that enterprise can get the highest value in unit time, namely making production scheduling based on the value density. After determining the bottleneck of workshop equipment, this method ensures that there are enough parts for processing in front of the equipment through scheduling and mixes human resources and equipment in scheduling, making implementation of task changes and lock or refuse of time window in dynamic status. Both the importance of order and time of delivery are considered in order to make full use of the workshop equipment capacity. Each task is computed for only one time, which is especially suitable for rapid production scheduling in dynamics.
