The allocation of interstage buffer storage capacity in production lines

In this paper, a simple optimal buffer capacity model is developed for series production line where the service time variability is described by the normal distribution and the buffers are allocated the same capacity. An expression is derived for the buffer capacity which minimizes the sum of the delay, inventory carrying, and storage facility costs. Practical data obtained from an actual production line manufacturing electric ceiling fans are used to illustrate the theory. Numerical comparisons are made with the results obtained using computer simulation. It is shown that the simple model developed in this paper provides a close approximation to the optimal buffer capacity for the production line considered. © 1986.link_to_subscribed_fulltex
