Interpretive structural modelling of critical success factor for lean product lifecycle management in industry 4.0

[EN] The industrial revolution has gone through four revolutions, this fourth one is Industry 4.0 or I4.0, which aims to improve the performance of companies by moving towards digitalization and relying on the internet of things technology IOT and the cyber physical system CPS. Lean-PLM is a system that has become a pillar of Industry 4.0 because of the benefits it brings: productivity improvement, performance, waste reduction. The objective of our study is to examine the correlation between Lean/Industry 4.0 and PLM/I4.0 and to present an implementation model using the ISM (Interpretive Structural Modelling of Critical Success Factor) method of Lean-PLM in Industry 4.0. The results obtained from this research show that Lean can be associated with Industry 4. 0, which gives us Lean 4.0, PLM is a pillar of Industry 4.0 and finally the success of the Lean-PLM model in Industry 4.0 is based on the support and commitment of top management , Big Data (BD) , Change Management and Professional Training and Development (PTD) .
