Solving the product mix problem using the harmony search algorithm

The product mix problem is a classical problem, which involves the decision to select the volume and mix of products that maximize the profit within the constraints of demand and production resources. Different approaches have been applied to solve this problem, among them, theory of constraints (TOC) has been widely considered since 1990s. In this paper, a harmony search (HS) algorithm is proposed to solve product mix problem. Also, the results obtained from the presented HS are compared with the results of some previous algorithms
