To complete this Slack idea (1999) she affirms that the area of Administration of the Production has as objective the production of goods and services to satisfy the consumer, through use of efficient resources for the production. Russomano (1995), defines then that the production is as a process that of organized form, it uses of insumos and it transforms these into a good or service to be executed. For Slack (1999), some functions exist as marketing, human resources, purchases, among others in an organization. Amongst these, the survival of all depends on the function production, therefore all the others are on it. With this the function production is central in a company and produces good services for the reason of the existence of an industry. The Administration of the Production and Operation is the applicable field of study of the concepts and techniques to the taking of decision in the function of Production (industrial companies) or Operations (companies of services) (MOREIRA, 2002, P. 03). Amongst some functions of the management of production one of them she is to direct the system by means of the decision taking.
Some decisions affect the project, others the operation of the system. The word production is on to the activities of the industry that are spread in the plant or the industrial production. In the industries that they manufacture physical and tangible products are common the supply and the standardization of insumos and products. Many industries are adopting the practical one of the just-in-teams, thus to diminish or to finish with its supplies. The project of a system involves decisions on capacity of the system, geographic localization of installations, organization of the departments and installation of the equipment inside of physical structures, planning of the product and the service and acquisition of the equipment.
