交貨期規劃-
The main idea of this hybrid algorithm is : at first, all candidates in task collection is lined according to a dispatching rule ( earliest due date, edd ), then this linear queue is divided into some tiers under a criterion that partial order is not allowed to exist in the every tier, many feasible sequences is generated by constructing a neighborhood of a initial sequence in every tier, the allocation of the resources over time is conducted to perform every feasible task sequence, and a set of approximate optimal scheduling schemes is achieved as the precondition of the next tier ’ s disposal in meeting multiple scheduling objectives to obtain the global near - optimal schedule which makes these program run tier by tier until the last task is completed
該演算法按照最早完工時間優先( ect )分派規則,先將參加排序的工序合併成一個串列序列,然後按照同層內不存在偏序關系的原則,將其分解為若干個時間上相互銜接的層次,在每個層次內部,通過構造鄰域產生出多個可行序列,對每個可行序列進行設備配置,採用鄰域搜索演算法進行方案的尋優,保留一組滿足評價要求的可行方案作為下一層設備配置的背景環境,通過層層遞進最終獲取全局的近似最優解。 -
A combined scheduling approach has been used for scheduling on the shopfloor. an interactive " pull " approach is used on the cell level and due date rule is used on the system on the system level. xu chunguang ( computer application ) directed by dr. huang yousen
採用「推拉」結合的調度機制,在單元級採用交互的「拉」式調度的方法,在系統級採用基於交貨期規則的「推」式調度,實現了車間調度。
