While the use of optimization models for production planning dates
back to at least the 1950s, the ability to represent the nonlinear
relationships between work releases and critical performance
measures such as lead times has remained a longstanding problem.
We review alternative approaches that have been used in the
literature, and then suggest a new approach using nonlinear clearing
functions that represent the relationship between the expected
throughput of a production resource in a planning period, and the
expected work in process inventory level at the resource over that
period. Extensive computational experiments show that the proposed
approach produces production plans which are more realistic in terms
of the production system's ability to execute them. We compare the
performance of clearing function models to those from iterative LP-
simulation methods, and discuss a number of extensions including
incorporation of stochastic demand.
