使MES的產生成為一種必然。但同時，復雜信息是一把雙刃劍，在給制造車間帶來機會和挑戰(zhàn)的同時，還可能會給其運行帶來負面影響。復雜信息會對系統(tǒng)優(yōu)化造成一定的影響如果缺乏復雜信息處理方法以及車間信息集成和共享機制，可能會使生產各環(huán)節(jié)銜接協(xié)調，按時完成任務的可能性降低，不能保證產品質量和交貨期，難以控制生產成本，從而影響生產過程總體優(yōu)化效果，最終用戶的滿意度會受到影響。復雜信息還會影響車間的穩(wěn)定性，由于生產過程中存在著許多不確定因素，例如加工時間的變化、產品需求量的變化、交貨期的改變及設備故障等，這些生產過程的變化對約束造成一定的影響，使模型中的信息變得不確定，有時即使通過部分軟約束的松弛吸收小的變化也會對原有靜態(tài)調度造成大的改變。再有，系統(tǒng)的行為也會受到影響，MES為了提高車間控制的效率和魯棒性等性能，不可避免地采用分布式的決策和控制，因此，部分分布決策單元之間可能會由于信息具有局部性且缺乏對系統(tǒng)全局狀態(tài)的認識而出現(xiàn)沖突的、不完全的、不確定的、延遲的等特性的信息。如果它們在這種對系統(tǒng)的狀態(tài)只具有延遲的和不完全的知識的情況下進行行動選擇等決策時，系統(tǒng)的動力學特征將十分復雜，就會產生非線性振蕩和混沌現(xiàn)象。同時，復雜信息會對管理目標產生一些負面影響，當不可預測的事件發(fā)生時，車間需要采取一定的應對措施，如改變原來的生產計劃、適當增加庫存、與顧客協(xié)商變更產品的交貨期等，這些都對企業(yè)的管理目標造成一定的影響。因此，在正確認識復雜信息的基礎上，有必要進一步探討MES復雜信息處理策略。
