Abstract:W e view state owened enterprises(SOEs)as a contract between the state and human capita1．There exists an unequal contractual relationship between them because the state adopts unilateral governance of the human capital by the contract．The appearance and existence of the contractual relmionship are relevant to the monopoly state ownership economy and the“catching—up”strategy enforced by govern ment．Although the unequal comractual relationship reduces the external transaction cost of SOEs largely,it increases its interna[transaction cost．Because the high internal transaction cost is the m ain reason for SOEs getting into diffieuhy in the transitional period the reform of the contractual relationship can not be delayed any longer．

Abstract:Agents reward system is critical to incentives in teams，which is one of the most important problems in incentive mechanisms designing theory．In this paper，we first improve the compensation mechanism for agents’share of risk in Pareto’s sense，then we optimally design the system for share of profit among agents，we also develop a relative performance evaluation system for agents in a group

Abstract:Hybrid systems based on genetic algorithms is a new methodology tO reform and promoting generic algorithms in theory and application． It integrates GAs with existing well done methods and algo rithms for optimization problems，such as optimization heuristics，domain knowledge acquisition etc.Thispaper studies three sorts of hybrid systems，and anaLyses the characteristics and performance of GAs hybridized with Neural Networks．Fuzzy Logic and Expert System

Abstract:In this paper the identification method for the nonlinear chaotic economic dynamical system based on timeseries is studied，and include the method of phase—randomized．the calculation method of its dimension，Lyapunov exponent and the singular value decomposition for the technology is studied carefully

Abstract:A systems analysis framework in Guilin case study of sustainable urban development is introduced in this paper．First．a regional sustainable development programming model and its application in urban industry structure optimization within environment capacity in Guilin city are presented．Second，a sustainable urban land use modehs constructed for optimization of industry distribution on urban area For the reasons of nonlinear and complex in this model，it isolved by Genetic Algorithms And then．in order to integrate decision makers’preference on multi—objects and their judgments on urban problems，discrete multicriteria decidon making melhods are utilized to improve the solutions obtained from urban industry optimization modeI and Iocation optimization mode1．At last．a muldmedia education system for this ease studyis implemented with Java on 1nternat／WWW

Abstract:This paper discusses s。rne basic problems about executive information systems(EIS)，a new kind of computer based information systems．The reasons that the applications of EIS have increased rapidly are analysed first．Its definition and the characters are then discussed．The differences among EIS and other kinds of computer based information systems are also studied．

Abstract:An architecture of a new generation of decision support system is proposed in this paper on the basis of evaluation of current several famous model reDresentati0ns and mod eling method s．And the advance these decades in model generation and model integration is also discused．At last the architecture of model management system which adopts object-orented model representation and machine learning theory to support Iraodel manipulation and knowledge acquisition is concluded．

Abstract:On the basis of analyzing the recent main views of the strategic management，the authors argure that corporation's strategic management should pay more attention on how the enterprise suiting，utilizing and making the change in the environment．The concept of Flexible Strategy is established，and the differenee in implication，nature and adapting field between Flexible Strategy and general strategy is also analyzed in this article．

Abstract:The aggregate production planning is one of the most important components of production systerns．Demands of the market and the customers are introd uced in the system of the evluation indices for production planning in this paper．and a kind of three phase formulation approach of aggregate production planning is proposed based on planning，optimization，and modification by feedback information．Finally，a framework of decision support system for the formulation process is recommended

Abstract:This article applies discrlminant analysis method in credit risk assessment in commercial banks． By comparing to logit method，we study efficiency of discriminant analysis．Issues relating to the potential and limitations of discriminant analysis as a traditional modeling tool are also addressed

Abstract:In this paper，some basic problems in bargaining theory and methodology are systematically summarized．The situation of study and the literature concerned for bargaining theory and methodology are reviewed．The developing tendency of bargaining theory and methodology is discussed from different aspects．Especially，this paper shows that the bargaining of non—utility preference and of multiobjecdve should be the important fields and that incomplete information problems be main content to be studied for bargaining theory and method ology．This paper is divided two parts．Here is part I

Abstract:This paper first introduces the basic concept and basic proecdure of comprehensive evaluation(CE)，then discusses the basic methods，application domains，and advantages and disadvantages of each method of CE，points Out the existing problems of CE．and finally analyses the research trends of CE．
