Determination of buffer sizes in assembly systems using theory of continuous time stochastic processes

A selecting appropriate buffer sizes for the assembly system is a complex task that must account for random fluctuations in production rates. After the analysis of assembly systems with two workstations and one buffer, a mathematical model of the buffer states is proposed using the theory of continuous time stochastic processes, and the probability of the buffer being full is determined as a function of buffer size. Then a progressive algorithm is introduced to determine the buffer sizes in an assembly system with more two workstations. Eventually, an experimental case is given to demonstrate the validity of this study

Modeling of common organizational structure for Reconfigurable Assembly System

In order to response to the changing market and overcome the disadvantage of the traditional assembly line, based on decomposition of a product family into several so-called Functional Objects, a common organizational structure for Reconfigurable Assembly System is proposed, which consists of truck line and assembly modules.
