Abstract:Both the suppliers and purchasers can increase their profits through suitable price discounts. In this pa2 per , a bi-level model representing the decision problemof price discounts and order policies with cooperation of both the supplier and purchaser in supply chain is proposed , and the algorithm based on the difference is used to solve the model . At last , a simple example illustrates that the bi-level model can express the relationship of supply and demand properly and can minimize the total cost of both the suppliers and the purchasers at the equilibrium state.

Abstract:The paper analyzes how the dominant producer , to control its technology standard which is mainstream in the market which the network externality exists. The results show that the intensity of network externality and scale of the installed base have great influence on the decision of the dominant producer when the dominant producer faces the threat of the cooperative behavior of the fringes. Only if network externality is small and the scale of installed base of the dominant producer is large , the dominant producer should monopolize its standard. And when the net2 work externality is large or the scale of installed base of the dominant producer is small , the dominant producer should fully or targetedly open its standard. When the government orders the dominant producer shouldn’t open tar2 getedly its standard , the social welfare might be impaired.

Abstract:Firstly , this paper describes that the firm have two boundaries , one is contract boundary , the other is le2 gal boundary. Secondly , based on the core of cooperative game , this paper argues about the functions of the asset specificity and the ratio of trade in confirming the boundaries

Abstract:The Job Shop scheduling problem with distinct due windows is discussed. Uncertain processing time is also considered , which is denoted by triangular fuzzy number , and two fuzzy operators are introduced also. Fuzzy programming model is established for the scheduling problem. Based on the algorithmof maximizing the membership function of middle value , the fuzzy programming model is transformed into deterministic programming model and an effective genetic algorithm is presented also. A great deal of simulation results are given to illustrate the efficiency of the proposed model and the scheduling algorithm.

Abstract:This paper presented a two2dimensional discrete dynamic competitive model in advertising based on the classic V2W model , namely the sales2advertising response model . In the duopoly market , goods produced by two companies are exchangeable , and so in order to increase sales they have to lend advertising to attract customers. Since advertising expenditures were used as control variable in this paper , the model could be regarded as a linear feedback control system. By means of mathematic analyzing and numerical computing , it can be obtained that two state variables is chaotic synchronization under certain parameters regions. Furthermore , the stability of the chaotic synchronization was also analyzed.

Abstract:This paper focuses on how irreversibility influences the effect of uncertainty on firm2level investment deci2 sion with theory of real option pricing. In empirical study , panel data on Sichuan and Chongqing 227 firms in period of 1998 —1999 is used to test predictions from models of irreversible investment under uncertainty. Survey informa2 tion on the entrepreneur’s subjective probability distribution over future demand for the firm’s products is used to construct the expected variance of demand , which is used as a measure of uncertainty. Empirical results support higher uncertainty raises the hurdle level that triggers investment . Moreover , the results have not sufficient evi2 dences to prove the prediction that firms wait to invest until the marginal revenue product of capital reaches a firm2 specific hurdle level , and some reasons for explaining this phenomenon are given.

Abstract:A model of incentive effects of senior debt and junior debt is developed in the paper , in which both the rate of inflation and the rate of dividend yield are incorporated. Using the method of the game theory analysis of op2 tions , the analytic valuation formulas of the senior debt , junior debt , equity and firm , respectively , is presented in the paper. The paper discuss that the effect of the rate of inflation and the rate of dividend yield on the firm’s bankruptcy decision , the firm’s decision to issue junior claims and this wealth transfer between the debt holders and the equity holder , respectively. In order to demonstrate that the rate of inflation and the rate of dividend yield can2 not be neglected in borrow2lend contracts.

Abstract::Many workflow2modeling tools have been developed , but most of them describe business process in terms of activity , product , goal or decision2making. Little attention is paid to roles and interactions among them. Howev2 er , the success of an enterprise depends on its people and their accountabilities in the final analysis. In this paper , role2oriented workflow modeling is analyzed from the perspective of roles and their interactions. Then how to repre2 sent the role2oriented workflow models is discussed , which provide a new method for workflow management . Fur2 thermore , with reference to the architecture of WFMC , role2driven approach to workflow management systems de2 scribed by multi2agent systems (MAS) is proposed based on the analysis of the relationship between agents and roles , between MAS and workflow systems. A prototype is realized based on the approach

Abstract:This paper first summarizes and classifies the comprehensive evaluation (CE) methods in different fields , and analyses the principles , virtues , shortages and their application fields of each method. It explores the newly re2 search development of CE methods. There are three major problems in existing methods : The first is the non-consis2 tency about the evaluation conclusion when using different CE methods ; the second is the lacking of special treat2 ment in practice ; the third is the disjoint between theory researches and practical applications. Based on this , the paper puts forward the new idea that the combined evaluation based on methods integration is to set up an I3DSS that supports the consistent evaluations
