Selection of tool steels is not limited to one type of steel for satisfying customer needs. On the other hand, technical specifications of tool steels are not absolute and it consistently deviates from the mean. Thus in this paper, the fuzzy logic theory has been used for selecting appropriate tool steels with price analysis. The main steps are as follows: 1. Defining and obtaining four technical features and prices of tool steels manufactured in Iran. 2. Calculating the mean and standard deviation of some technical features. 3. Defining and establishing relevant membership functions. 4. Relating tool steels to the amount of their favourability for customers. 5. Determining customer’s desirable tool steels by using fuzzy logic theory. In this paper, the possibility of reducing tool steels variety is also provided, leading to a decrease in the total cost of tool steels for the manufacturer.
