Constructs Based On System Dynamics Decision Simulation Laboratory With The Application

The modern enterprise is has the widespread relation with the external economy system the open system, involves the factor are very many, also has the very big not definite gentle breeze danger, the enterprise only has achieves the effective decision-making to be able to be able to survive and the development. Obviously, only depended on individual experience and the knowledge carries on the decision-making already not to be able to adapt enterprise's development, how carried on the macro-scientific decision to become the important topic which the enterprise needed to study. The decision simulation laboratory produces which along with the computer technology and the management theory development may carry on the correct decision for the enterprise to provide the guarantee.The author has used the systems dynamics theory, the tool and the method, has carried on the discussion to decision simulation laboratory constructing with the application. The author acted according to many year practices to give the decision simulation laboratory understanding triangle concept, enable the people to have a clear understanding to the decision simulation laboratory. Constructs in the process in the decision simulation laboratory, the author has applied the tradition software engineering method and "from the top downward, gradually the refinement" the design concept, discussed the decision simulation laboratory to construct the principle and the concrete step, has designed the decision simulation laboratory construction four parts: Model management system management system, user interface system, data model system and knowledge management system management system. The author uses the systemic circulation chart and the systems dynamics modelling two kind of modelling tools, the application rapid application development model method carries on the decision simulation system modelling, the recombination Ithink software system may establish one based on the systems dynamics decision simulation laboratory. Decision simulation laboratory constructs which through this article to each kind of decision plan after simulation, may discover the most superior decision plan, has realized enterprise's macro-scientific decision.The author applied the decision simulation laboratory which constructed based on the systems dynamics for the Nanjing Hongbaoli biological technology limited company to carry on the investment decision analysis, this decision simulation laboratory take the finance as a core, has contained the production and the stock, the market and the marketing, the management and the cost and so on five sub-systems, will invest the recoupment period and the economic efficiency takes the appraisal the major targets or quotas. Indicated after the actual movement result that, carries on the macro-scientific decision through the decision simulation laboratory is quite suitable.
