本文通過對厚壁管件無芯棒開式冷擠壓尺寸預測的實驗研究，分析了影響相對伸長量的犯要參數，找出了它們與相對伸長量之間的變化規律曲線，為指導實際生產提供了依據。Details are as follows : we deal with properties of bilevel linear programming and prove the equivalence of bilevel linear programming and optimization over the efficient set. a class of multi - objective tow level programming, i. e. the upper - level is single objective and the lower - level is linear multi - objective, is mainly discussed. it can be converted into the optimization over the efficient set with parameter and an algorithm is given with its finite termination being proved ; when the upper - level is linear function, an exact penalty function algorithm is given
分層（分級）遞階系統是社會組織管理的主要形式，多層規劃是研究這類系統優化問題的基本模型，其鮮明的實際背景和廣泛的應用前景引起了人們的廣泛關注，成為一個新興的活躍的研究領域，本論文研究了二層規劃中的若干問題，主要工作如下：討論了二層線性規劃的性質，並證明了它與零有效集上優化問題的等價性；對一類二層多目標規劃（上層為單目標規劃、下層為線性多目標規劃的問題）進行了探討，將其轉化為含參變量的有效集上的優化問題，進而給出了一種演算法，並證明了該演算法的有限終止性；當上層為線性單目標時，給出了一種罰函數方法It is one of the most important works to run economically in today and future. the system of electric control automation in zhao zhaou is open, it bases on the net of rs485 bus control and centrally manages substation by control the main machine. the system controls the run parameter of electric equipment and the run environment by using the computer measure, communication and automation technology, it can realize measure, communicate, control and allocate in the remote area, transmit data and control through collect data and automatic count parameter
肇州縣電力調度自動化系統是以rs485總線工業現場控制網路為基礎，通過監控主機對變電站進行集中管理的完全開放式系統，該系統綜合了計算機、測量、通訊和自動化的專業技術來監控電力設備的運行參數、監控運行環境，通過對輸變電線路及設備的交流電壓、電流的數據採集，自動計算出功率、電量、功率因數、頻率等參數，實現四遙：遙測、遙信、遙控、遙調及數據傳輸和監控功能。First, because pipelines are so complex that controlled object is high order, delay, coupling, nolinear and time - varing, it is difficult to realize closed loop control for it using valid mathematic model. to resolve this problem, the paper presents a fuzzy - pid control algorithm with self - adjusting regulation factor. second, if a moving motor supplied by inverter power is switched to be supplied by power supply, the impact of overload - voltage and overload - current appears
主要針對中、大容量供水系統中，由於供水管網鋪設復雜、彎管多、控制對象具有高階、滯后、耦合、非線性及參數時變的特點，難以利用有效的解析式數學模型進行閉環控制，以及多臺水泵並聯運行時，水泵電機由變頻電源供電向工頻電源供電切換過程中產生的過電壓過電流沖擊這兩個難題，提出了可調整因子fuzzy - pid控制演算法及利用鎖相環控制實現水泵電機由變頻電源向工頻電源的同頻同相平滑切換。Finally, as a main basis to form objective system of sgee, a target system of sgee ' s briskness measure has been given out simply and clearly by those two results, the author has completed the four designs of sgee ' s em from principle structure to practical use, that is : the pressure em for worker ' s to be effectively consciousness the payment em based upon the conclusion in the research that the model of management by objective should be mainly adopted in sgee ; according to situation of sgee, this mechanism has feature of simple contribution estimation, and comprehensive measure about present and long term contribution of workers the concept em that could be used to greatly raise condensation force in enterprise the growth em that is favorable to bring up excellent talent finally, the ibm system as a exploratory, the rules of operation and regulation were put forward about ibm of sgee in this paper, include : influence factors of living cycle of iem laying and operating programs based on the need of practical uses a measure model of relation effect of iem, based on the newton second theorem regular ways to iem based on the control theory
為尋找實用性較強的機制參數（變量） ，本文對發電企業內外部環境進行了分析，其中，內部環境分析以研究后重組的活力構成要素為線索展開，通過逐項延伸分析，簡明扼要地提出了發電企業活力衡量指標體系，作為形成發電企業目標樹圖的主要依據。以上兩方面的工作成果，使筆者最終完成了發電企業四項激勵機制從原理、結構到實用性的綜合設計，即： ?有效激發員工市場競爭意識的壓力激勵機制。 ?基於發電企業應當主要採用目標管理模式這一研究結論的報酬激勵機制，它的最大特點是簡化了績效評價，針對發電企業現狀，在機制中注入了人本管理思想，綜合考慮了員工對企業當前和長遠利益的貢獻。分享友人
