Fuzzy-set theoretic interpretation of economic order quantity

Abstract

Although the economic order quantity (EOQ) formula is probably one of the most famous formulas in the industrial management field, the composition and estimation of the cost parameters have always been vague and imprecise at best. In view of the inherently fuzzy aspect of the cost determination, the EOQ formula is reexamined in a fuzzy-set-theoretic perspective. An introduction to fuzzy systems theory is also provided.
