The proper management of the operations is fundamental to the companies' results, and, particularly, the continuous improvement in production processes is extremely important to raise the level of efficiency. The present study aimed to simulate the process of welding of a component called heat exchanger that makes up a gas water heater. Then, this simulation has the objective of optimizing the production process. The data collected were obtained from a company located in Mogi das Cruzes, São Paulo. The results of the simulation model point to opportunities for improvement, mainly in the direction of reducing work shifts.
Entrepreneurship is hard work, especially when it comes to the creation of an innovative, ecologically correct and sustainable project, and the small entrepreneur, in addition to facing bureaucratic and fiscal obstacles, has great difficulty in running his business, planning and optimizing his production for lack structured management knowledge. This is what happens with the company studied, where the construction of an educational centre, thought to be a model of ecological and sustainable building, did not have a schedule of execution, thus becoming dependent on very short term planning, accomplished at each step, rather than a structured action as a whole. In this sense, the Critical Path Method (CPM), which uses simple estimates for the duration of the building stages and the PERT technique, was implemented among a variety of schedules and methods for planning and control of works execution.
