Visualization Human-computer Interaction Decision-making Study

Decision Support System(DSS) has been developed rapidly as information system was combined with decision-making technology. At present DSS has become the important research subject in the field of systems engineering and computer application. Almost all the researches and exploits of DSS stress the supporting action to decision-maker. The action of the human-computer interface is the most important part. It is a fact that designing the human-computer interface is the important factor if DSS is successful. According to it the paper developed a prototype of process-based Visualized Assistant Decision System in terms of the visualized human-computer interactive decision-making technology. Main achievements are as follows.At first the paper analyses and concludes the characteristics of the technology and methods on the multiple-attribute decision-making. Then the guide subsystem of decision-making problem is developed to lead users to input the useful information of the problem. The other guide subsystem is presented to lead users to get weight coefficient of the problem. The paper discusses the visualization of preference and presents the method for the visualization of preference. The methods base is designed to be the form of DLL. So it is easy to extend the system and add the new methods.The data-base is designed to save the information of the problem and the decision-making methods...
