Abstract:Information gathering is the key issue to idea generation in group deeNion suppot system(GDSS)．In this paper，the information gathering process in GDSS environment is divided into three phases．The characteristic and tasks of each phase are given．Using the multi—agent based group problem solving approach，we present a inform ation gathering framework for designing GDSS．

Abstract:This paper studies the analysis method for analyzing the impact of information systems technology on the competitive domain of firms based on the mod el for analyzing industries and competitors． The analysis is performed at three leve1．The impact of information systems technology on industry level is analyzed first．Its impacts on firm level and strategy level are then studied，resepectively．The applications of in form ation systems technology to firms can be better made with this analysis.

Abstract:In this paper，some basic problems in bargaining theory and method ology are systematically summarized.The situation of study and the literature concerned for bargaining theory and method ology are reviewed．The developing tendency of bargaining theory and methodology is discussed from different as peers．Especially，this paper shows that the bargaining of non—utility preference and of multiobjective 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 partⅡ．

Abstract:This paper surveys several main models for bidding and auctions，including models of Friedman， Gates，Hanssman—Rivett and W illenbrock，respectively．These models are also commented briefly in this paper

Abstract:By an integration of the techniques of the neural network，genetic algorithm ，expert system ，simulation and production scheduling，the function and component of Production Scheduling Expert Simulation System are discussed．The management method s in prod uction scheduling and its implement mechanism are also studied

Abstract:This paper starts from concept of anonymity and combines organlzation behavior with managerial psychology.Firstly，we analyze the positive and negative effects of anonymity in an integrated& systematm way.Secondly the concept of anonymous intensity is put forward according to the anonvrr1ous operation degree in practice．Thirdly，major factors tHat influence the anonymous intensity are analyzed． Fina11y，the paper discusses the effective application of anonymous intensity with considering the goal of group task，task type and group features to improve the group performance

Abstract:On the basis of analyzing the composition of regional“Ec—R—Ev”Complex System and the inter connected relations between its elements，we set up the structural model of the system using the improvedmethod of interpretive structural modeling to make the relation of elements clear and a good preparation for further quantitative research．

Abstract:In this paper，we analyse the fund flow occurred in the process of the production and business of enterprises，then the model for the fund flow in the double—entry accounting system is presented with Colored Petri Net(CPN )，and a state equation mod el based on CPN model is described．which has given the efficient method for studying computer accounting information system

Abstract:1997's Nobel Economics Prize was awarded to Robert Merton and Myron Scholes for their distinguished contribution to option pricing theory．Option pricing theory is closely related to practical operations in financial markets and has significant impact on the development of western financial markets．Black and Scholes published the first option pricing model in 1973，Merton and other researchers continuedtheir work，further developed the model，gaining in the process more perfection and wider application for the theory．These theoretical results have been directly applied to business and stimulated the rapid growth of derivative trades．Options are very complicated types of derivatires，they are contingent claims in future．Their valuation and pricing are complex and difficult．The no—arbitrage hedging position should be adjusted continuously and described using stochastic differential equation．This article illustrates the fundamental option pricing theory and discusses its extension and significance in both academic and business fields

Abstract:In the actual development of Information Systems，DSS can only support the selection st ge，not the other two stages which are inseparable from the whole decision—making process．i．e．the intelligence collection stage and the solution design stage．In this paper，the possible methods in which ES can be integrated with DSS，EIS and ESS are analyzed．In view of that different types of application systems can afford different supports for three stages of decision—making process，and that there are some logical relations 0f data proces among those systems，the application systems are reclasified，and the application systems integration framework in support of the high—level management decision and in suppo rt of the whole decision—making process is proposed．

Abstract:There are many methods for model representation in DSS generator，such as first order logic， knowledge abstractions，macro，relational framework，and soon．All of these methods ignore the important components of model：expression，which is the basis of mode1．This paper presents a new method to represent model in DSS generator．M od els in DSSg can be viewed as having three levels：Theoretical model，Attribute mod el，and Value mode1．This three level model must be represented in DSSg．A DSSg named as 3 DSSg have been developed based on 3 level model representation method and have been used to developspecific DSS

Abstract:Approaching the fuzzy problems that Case Based Support system often face，this paper presents a kind of case based support systems using fuzzy neural technology(FNCBSS)．As a kind of intellignet decision support systems，because it has fuzzy logic inference and learning functions，it is more similar to the mental cognitive process of mankind．The paper gives and analyses the principle strcture of the FNCBSS and also points OUt its fessibilities from the theorical perspective and the difficulties it will hoe in appfication．In the end．it discusses the future of the FNCBSS developement．

Abstract:This paper extends the analyses by Tabuehi on transport pricing and modal split when there is a mass transit parallel to a road with a bottleneck between a residential area and a workplace．The extensions are in two aspects，one considering the effects caused by discomfort of mass transit，another treating the travel time difference between two modes．Through studying the equilibrium of COSTS incurred on individuals， we investigate the flow distributions resulting from several transit fare and road—use tolling schemes and compare the individua1 perceived COSTS as wel1 as the tota1 social costs．Some usefu1 insights different from previous understandings on this problem are derived．The policy which utilizes the revenue generated from road—use tolling to subsidize transit，is also discussed.

Abstract:In this paper，the regulation rules of the disequilibrium economics for micro—macro single market and multi market are studied at the optimal control theory angle．At last，the practical analysis of the adjustment for disequilibrium is made for Chinses economics．

Abstract:The GDSS Structure based on indM dual preference announcement and cognitive feedback extends the content of reciprocity of GDSS group．A theory supporting group continuous development is described in the paper．To enhance self—knowing，to rich the exchanging content，to further learning and understanding among group's members，and to offer credit measure tools are focal points of the theory．
