Study Of The Decision Support System Based On The Life Cycle Cost Theory And It's Software

The paper researches a decision support system that can adjust to modernization engineering need, because the life cycle cost theory in the technology economics is introduced. It combines computer technology, decision science and technology economics. A quantitative decision gist is furnished to decision-maker at cost. New-style decision support system is always popular research areas based on combining decision science with other science technology.The paper expounds the life cycle cost theory in the technology economics. At this point, the factors of influence equipment life cycle cost are analyzed. Aimed at the large harbor enterprise, an applied decomposed framework of equipment life cycle cost is advanced. The instance proves that the decomposed framework establishes a nicer basic to gather and manage cost data, and to provide applied data for decision support system.In order to offer model for model system of decision support system, data processing techniques of neural network etc. dynamic and no need user-defined dimension are used to modeling. When using BP neural network deals with the data of the big numerical value like cost, using common methods of changing concealed node number etc. don't improve the things that the simulated curve is low precision or transpires. So data processing course of network is investigated. A new data processing method is advanced to apply graphics zoom theory. Its feasibility and validity are proved through the instance. At the same time, in order to investigate to distill a new method of useful information of a database, data processing methods of using neural network and fuzzy math are specially investigated. A new thought of speedy and accurate forecasting data is advanced to use BP and RBF network. And applying fuzzy math in series with neural network distills the grade of membership value of data.In order to enlarge engineering fact application function of decision support system, decision science is combined with life cycle cost theory of technology economics. An applied method of equipment updating occasion is advanced. Its validity is proved through the instance.Application condition of decision support system software and peculiarity of current fashion computer software are analyzed. A new method of integration manifold fashion program language is advanced. It can rapidly open up a largerapplication. The paper investigates methods of software integration home and interface technology between per software. To apply the method, a larger decision support system of being able to use to a fact engineering is rapidly, high efficiently opened up.A few things on the visualized modeling are finished. A visual port equipment computer assistant decision support system based on life cycle cost theory is developed for the first time in our country. The system is made up of data management module, query module, modeling module, data processing module and results display module. It has some advantages such as self-study, dynamic modeling, high speed, highly visual and use expediency. The software directly runs under Windows operating system.
