Estudo de viabilidade técnica e econômica de um protótipo para a locomoção de pessoas com mobilidade reduzida

Abstract

This work presents a study in regard to Production Planning and Control (PPC) and analyzes the fundamentals that guide the management of a production system considered on demand. All necessary processes were verified for the prototype production in addition to its time management and activity sequencing through PERT/CPM methodology. The analysis of economic viability was also verified and based on classic methodology, expanded multi-index methodology and Monte Carlo simulation, these were applied in computational software in order to verify the economic indicators that will assist in decision making in the investment plan. In this context, the possibility of domestic production of a mechanical prototype or its outsourcing are considered. Three scenarios are discussed, the first one considers the in-house production, the second one considers the outsourcing of the production stages, and the third one analyzes beyond the outsourcing of the production, also considering the replacement of components for others relatively less expensive. The obtained results allowed the evaluation of the performance that the investment plan will have on the planning horizon through the economic indices. T he scenario with better performance indices was the third in analysis, this was verified outsourcing production resulting in a lower initial investment and replacement of components by other less costly.
