Summary
There is no doubt that manufacturers schedule operations - without doing so, product would never be shipped. However, what seems to receive comparatively little attention in many organizations is discussion on how to assign or release jobs throughout the facility in order to optimize the scheduling activity. This paper describes a general scheduling environment, known as the hybrid flow shop (HFS), which exists in many facilities. For example, surface mount assembly is one type of production flow that can be modeled as a hybrid flow shop. Fundamental concepts of HFS scheduling, performance metrics tied to costs and facility utilization, and developments towards improved scheduling techniques for HFS are reviewed in this work.
