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。 -
