Estudo de viabilidade econômica da alteração do processo de moldagem de chapas de fogão a lenha

Abstract

This paper aims to analyze the economic feasibility of installing a molding system in a foundry, which produces cast iron, located on the Paraná Southwest. The research is characterized as a case study, using the Expanded Multi-index Methodology (EMIM) and quantitative analysis tool web application $V€ and programming spreadsheets in MS-Excel. The economic viability of the investment project (IP) was obtained from comparisons of productivity and associated costs between the current production process (Pep Set) and the system under study (Cold-Box). In this case, the cost difference is considered the sales price of the product. However, with the implementation of this IP, the values may have variations due to a fluctuation of demand for products and changes in the costs of raw materials. To address these changes, we used a probabilistic technique via scenario analysis. Even for the worst case scenario considered, the IP resulted in a return considered high-grade and low risks. Therefore, we recommend the implementation of the new molding system.
