Eliminação de desperdícios sob a ótica do Lean Manufacturing em uma pequena indústria do setor carvoeiro

Abstract

Lean Manufacturing began after the World War II, when the Japanese industry was forced to reshape their manufacturing methods due to lack of resources, resulting in the Toyota Production System (TPS), which aimed to produce at the lowest cost possible and removing existing waste. Following this context, this paper presents a case study of the wastes that influence the production process of the coal industry sector located in the Midwest of São Paulo State. For the purposes of the study, a case study in the company was conducted, and the preparation of tables and interviews to collect data, which aimed to understand what activities could reduce/eliminate the production waste. It was found that the transportation and handling wastes are the most critical. Thus, CRAFT software was used to perform a simulation of possible layouts to reduce such waste to the industry, and it resulted in a possible increase of 20% in productivity in case of the company adopts this change, since the distance between the departments can be reduced.
