Just to kick in some more vocabulary conventions - Waiting time in system = waiting time in queue plus service time (These definitions are from Hillier & Lieberman, Introduction to Operations Research.) Their setup is a queue feeding a service facility. --- Reinertsen (Managing the Design Factory) - also talking from a queueing theory viewpoint - uses the terms "time in the system", "queue time", and "service time" for the same concepts. --- Another definition: Cycle time - time between the completion of the last product and completion of the next product. Production lead time - time between beginning of production and completion of production This is from Suzaki, The New Manufacturing Challenge, p. 131. He shows an assembly line, with cars in various states of completeness. He shows cycle time as the gap between two cars, and production lead time as the time from initiation to completion of a car. (I don't think we need new terms for most of this stuff, let's just use an existing set where we can.) --Bill Wake ------------------------ Yahoo!
