Implementing Synchro-MRP through Value Stream Mapping

What is it about?

Value Stream Mapping (VSM) is recognized as the main tool for implementing lean manufacturing. Unfortunately, it always leads to pure pull systems and discourages the adoption of hybrid push/pull ones. This paper presents an enhancement of the standard VSM, which supports the user in implementing a synchro-MRP system.

Why is it important?

The paper presents new mapping icons, mathematical formulas and operating guidelines to assess the benefits of a synchro-MRP system, with respect to the usual kanban or CONWIP ones. Also, an industrial application of relevance is presented, to demonstrate the quality and the utility of the proposed approach.
