Abstract

Over the last years, the industrial energy consumption has become a critical issue and several energy management systems have been developed. At the same time, the lean philosophy has been used to evaluate the critical points of the production processes. One of the main tools used by lean champions is the Value Stream Mapping (VSM) to identify “bottlenecks” and also to provide graphically areas of interest for improvement within the shop floor. Current VSM models do not include information about energy as a fundamental content. To overcome this lack, the present work is focused on the development of a new extended VSM tool able to map the energy consumption. Energy value Stream mapping (EVSM) is a tool to evaluate issues related to the energy consumption. Through it, the energy manager can pursue the minimum energy consumption. The proposed tool has been applied and tested in a real case study.
