  7. Abstract:
  8. In today’s industrial world production is considered as a competitive weapon. This has caused many companies active in this field to move towards creating competitive advantage to reduce costs of design, construction and increase production. In particular molding as one of the main industries is among the most economical technological resources of each country. About 50 to 70 percent of the price of a production operation is spent of the strip of sheet by pressing; thus the proper design of a strip of sheet has a great impact on the mold design. Today, in most sectors of the industry there is a need for cutting and packaging of products and form molding and glass cutting to fitting the electronic chips on the IC space are all applications of two-dimensional packaging problem. In all these cases and other cases there is a need for optimality, less space and materials are the first condition for benefit. The researchers have proposed a variety of methods to solve this problem but as the problem becomes grater and based on the time limit to get the optimal results, the heuristic methods seem to be more applicable than other methods and one of the methods that have obtained an acceptable solution in the proper time is the genetic algorithm. This research with the focus on the genetic algorithm structure and the attempt to resolve the weaknesses of the similar approaches has obtained appropriate results. Finally, using the results of the system it has analyzed two conventional pressing methods in production economically
