Developing a knowledge-based decision making system to select the steels of dies for sheet-metal forming

Material selection is a problem solving and decison making process. In the selection of die materials, some points are very important. For this reasons, databases are not enough to select the steels of dies for sheet metal in themselves. They do not incorporate data relating to all of the contributing factors needed for quantitive interpretations. To solve the user's problem are requried expertises and knowledge obtained from experts, ln this study, a knowledge-based decision making system is introduced which is included the knowledge and experiences of the experts that subject formed from roles and there is a database including the cfaaracterictics of die steels. In this system also comprises decision making mechanizm that selects suitable die steels by using user interface.
