SWOT-based Intelligent Dynamic Strategy Decision Support System

As our country has jioned into WTO and the economic system has been perfected gradually, the reform and opening policy of China has maken great progress, all kinds of enterprises have to face the opportunity and challenge of the development, every one should think deeply about that how they can hold the chance. But, there are some companies which almostly have no ability to face the intense competition. In the operating mode of planned economy, many enterprises got into a hobble due to the enterprises' culture of "iron bowl" and "mess". Recently, with the development of scientific technology and wide application of computer and internet, human is stepping into a new age. The strategic situation that enterprises face, is bacoming badder. Strategic decision is more important than any time. Expert's qualitative knowledge or qualitative judgments and quantitative model and quantitative datum are needed to be combined hormonally in order to realize interaction of qualitative knowledge and quantitative datum, but it is impossible only by method of traditional manpower and brain of human being. So more efficient strategic decision-making by computer should be utilized researching computer support system adapting to utilization of high level. In order to meet the need of strategy decision-making, in 1970's executive system facing strategy decision-making of firm and stategy information system based on MIS and developed into SDSS. As one of research branches of Decision Support System (short for DSS), the framework of SDSS and design principium of SDSS developed forward focusing on that facing high decision-maker of firm.Firstly, this thesis applies the thought of integrating qualitative method and quantitative, bringing thought of disassemble by degrees and the integration of qualitative information and quantitative data. By this thought, discussing the integration mode of qualitative model and quantitative one, as well as the switching map relation between qualitative knowledge and quantitative data, bringing the DSS system structure of integrating qualitative reason and qualitative calculation and analysis flow of intelligent system of dealing with question. Every function module is discussed simply. Then, on the basis of traditional SWOT analysis, the strategy choice is divided into the satisfaction of two restricts: strategy status and strategy project. So, the SWOT-Based Double Restricting Strategic Decision Model, SDRSDM, is established. By SDRSDM, decision-maker ensures strategic status of enterprise firstly to show the strategic station of enterprise in competition environment. The suitable strategic project is found in matching strategy objectively and reasoningly. According to the complex and dynamic character of strategic situation, the reasoning thought of SWOT analysis is put forward. Making the risk analysis of investment enterprise as example, discussing the possibility of building other predict model. Then, absorbing the thought of integrating qualitative analysis and quantitative and based on the effecting factors analysis as well as the qualitative judgement ability of experts and quantitative calculating model, the reasonable mark and power confirming method is established to raise the reliability of factor analysis. As the following, the ODT and SODT are developed to express the solving process of SDRSDM, that benefit for the model and reason. So, the solving process is united in different nodes of the whole ODT. In this base, the reason is studied so that the base of SDRSDM is settled. In addition, we find that solving SDRSDM is a abnormal complex decision system. So, based ANN, complex strategic decision support system is developed. The ANN studying elements for complex SDRSDM is studied. Based the three-layer BP study arithmetic, the AMM model of studying the knowledge of experts is established. Finally, based on the analysis of above chapters, a apply prototype of intelligent dynamic strategic decision support system, that is based on SDRSDM, is designed and implemented. System's basi...
