“Sometimes referred to as “single-piece flow” or “continuous flow,” one-piece flow is a key concept within the Toyota Production System. Achieving one-piece flow helps manufacturers achieve true just-in-time manufacturing. That is, the right parts can be made available when they are needed in the quantity they are needed. In the simplest of terms, one-piece flow means that parts are moved through operations from step to step with no work-in-process (WIP) in between either one piece at a time or a small batch at a time. This system works best in combination with a cellular layout in which all necessary equipment is located within a cell in the sequence in which it is used.”
In the current issue of Reliable Plant, Darren Dolcemascolo explains the concept and the value of one-piece flow in simple terms, including the prerequisites for it to work.
