Abstract : this paper discussed two mathematical models for the problem of selecting an expansion plan over a planning horizon for an electric utility system. one of which is the model of optimal sequencing of power plants which is solved using lagrangian relaxation. another is the model of operation. the paper explicated concrete application of the lagrangian relaxation method in calculating block diagram for sloving the scheduling model and considered variable operating expense when calculating
文摘:運用系統工程方法，建立了火電站興建次序優化模型及火電站運行方式模型，採用拉格朗日鬆弛法研究火電站興建次序的優化，並給出了火電站興建次序優化模型的拉朗日鬆弛法計算.在優化計算過程中考慮了可變運行費用問題 -

Firstly, based on the development history and characteristics of stock market the thesis looked back the development history and characteristics of every stage of chinese stockjobbers laid stress on the business development and risk management. secondly, the thesis analyzed the existing comprehensive evaluation method and choosed or model of data envelopment analysis as evaluation model. then we analyzed the deficiency of ( 7r model and established two new model - average value model, go model and its corresponding projection model - which were used to evaluating and sequencing fourteen comprehensive stockjobbers and draw a conclusion based on computation result of the three models
本文首先以我國證券市場發展歷史及特點為基礎，回顧我國證券公司發展歷程及各階段經營特點，主要分析證券公司業務發展和風險管理狀況；其次，對證券公司現有評價方法進行研究，選擇數據包絡分析（ dea ）的c _ 2r模型作為對證券公司進行評價的數學模型，針對c _ 2r模型排序時存在的並列第一和零權重問題，提出均值模型、 g _ 0模型及相應的投影模型，並對三種模型的計算復雜度進行了討論；第三，選擇14家綜合類證券公司進行實證研究並對三種模型的計算結果進行了對比分析；最後，簡要總結2001年證券市場狀況並對證券公司今後面臨的機遇和挑戰進行了分析。 -
