Using Multicriteria Decision Making Methods to Manage Systems Obsolescence

Systems obsolescence may cause huge invisible internal cost through mis-judgment. It leads to many defects related to the manufacturing system and its environment. While its management is complex, composed by multiple factors and stakeholders, the current tools are still minimal and purely quantitative using cost optimization only. Considering different actors seems essential to ensure a reliable mitigation and resolution strategy. This paper aims to develop an MCDM model specific to obsolescence management by expanding decision criteria and using a non-compensatory and dynamically weighted ELECTRE III approach. The goal is to ensure a robust, sustainable and green manufacturing ecosystem. The MCDM tool was applied to the problem and performed in two case studies from the literature, using DIVIZ platform. The model results were compared to those from previous studies. They show that the decision made changes significantly affecting the manufacturing performance.
