Mathematical models for a batch scheduling problem to minimize earliness and tardiness
Today’s manufacturing facilities are challenged by highly customized products and just in time
manufacturing and delivery of these products. In this study, a batch scheduling problem has been
addressed to enable on-time completion of customer orders in a lean manufacturing environment. The
problem is optimizing the partitioning of product components into batches and scheduling of the
resulting batches where each customer order is received as a set of products made of various components.
Three different mathematical models for minimization of total
earliness and tardiness of customer orders are developed to provide on-time completion of customer
orders and also, to avoid excess final product inventory. The first model is a non-linear integer
programming model whereas the second is a linearized version of the first. Finally, to solve larger sized
instances of the problem, an alternative linear integer model is presented
