Lean manufacturing has helped companies to achieve reduced lean wastage, productivity, quality, and resource optimization. Value stream mapping (VSM) is an important tool in achieving lean orientation. It helps companies in enhancing the competitiveness of their production systems. Although, VSM is a very useful tool to achieve lean orientation, it suffers from several drawbacks. It is static pencil-and-paper tool. It cannot handle complex value streams. It does take into account monetary measures e.g. profitability of the value stream. Also, it does not include environmental impact of the value stream. This research paper overcomes the drawbacks of the VSM tool through an innovative framework involving the usage of discrete event simulation, box score, and life cycle assessment (lca).
