Abstract

This paper proposes a batch scheduling and operator assignment model where more than one operators can be assigned to each machine. There are a number of parts to be processed in batches where each batch is to be processed through a number of operations for which there are alternative operators with different setup and processing times. Each operator will be assigned to at most one machine, and at least one operator will be assigned to each machine. The decision variables are assignment of each operator to each machine, the number of batches, batch sizes and the schedule of the resulting batches. A proposed algorithm is developed by trying different number of batch, starting from one, and then increasing the starting number of batches one by one until the objective function value does not improve anymore. Numerical examples are demonstrated to show how the algorithm works and result global-optimal solutions for the investigated problem. Keywords : Batch scheduling, operator assignment, flow shop, actual flow time.
