An extension of the extended basic period approach for economic lot scheduling problems

This paper addresses the problem of choosing cyclical production patterns for several products which are produced on a common production facility. The extended basic period approach of Elmaghraby is extended by allowing more than two basic periods. The problem of dimensionality of the dynamic programming formulation is dealt with by aggregating the capacity data in different basic periods.The author is indebted to Dr. S. E. Elmaghraby for inspiring him to work on the economic lot scheduling problem and for many valuable suggestions. The author is also grateful to Mr. Z. Naman for carrying out the computer programming.
