If it is not good enough, optimal control module based on principle component analysis and clustering search will function for optimization. this algorithm makes no request for accurate analytical model and maintains search efficiency and self - adjusting performance by an optimal parameter set derived from process data, which is proved to be effective. by practical running of dcs, a prominent tracing performance is gained and variation of parameters is limited in a small range, which enhance stability and production benefit of sintering process obviously
燒結過程是一個影響因素復雜、干擾嚴重、具有不確定性的工業過程,傳統的基於對象精確解析模型的優化策略難以奏效,因此在控制參數優化模塊中提出了一種基於主元分析和聚類搜索的優化匹配演算法,該演算法不要求對象的精確模型,其搜索效率和自校正性能依賴于從生產過程歷史數據中抽取的優化參數樣
本庫,充分利用了燒結生產過程積累的生產數據所包含的信息,取得了不錯的效果。

The theories foundation of activity - based costing, is to think that the production line should describe for : the production causes activity take place, the product consumes to used to the industry, the function consumes with the resources, thus causing cost take place. this with traditional manufacturing costing the product consume with the cost of principle is different. thus, the activity - based costing checked to track the process of the product formation and the cost backlog with the activity - based costing, carry on make track for to the cost formation to trace to origins originally, set out from here, activity - base method makes research of cost gone deep into more, the cost information is more detailed and turn and even have and can control it

In this thesis, we adopt the technique of statistical training, create a sample database of every kinds of expression face images, construct a matrix of the difference of each sample and average image, and reduce dimension by pca, then decrease the relativity of principle components by ica, and therefore get the character sub - space of face. when detecting a face, we adopt the method of disturbing principle components of model to match special facial image, which is called whole optimization method in this thesis
論文採用統計訓練的思想,選擇包括各種表情變化的人臉圖像建立樣
本庫,取所有樣
本與平均圖像的差構造一個矩陣,利用主元分析方法進行降維,然後通過獨立元分析降低主元相關性,建立了人臉的特徵子空間;演算法採取對主元進行擾動優化匹配的方法檢測人臉,
本文稱此方法為全局最優的方法。

The findings are that it is optimal to use base - stock policy. the second section assumes that outer ordering incurs fixed ordering cost, then outer ordering uses ( r, q ) policy, while inner ordering uses base - stock policy
第二節在第一節的基礎上,假設外部訂貨時訂購費存在,這時外部訂貨採用固定訂貨點、固定訂貨量( r , q )策略,而內部訂貨仍採用前面的基本庫存策略。
