The function of 'scheduling' is the time-sequenced allocation of resources, such as machines, personnel, tools, and component materials, to perform a collection of tasks to manufacture products. Traditional methods of scheduling have used infinite-capacity and static-time calculation approaches. The result of these methods are inaccurate and non-representative answers to extremely important questions. Discrete event simulation can provide a very accurate and effective engine to address scheduling issues. The paper introduces AutoSched, a discrete-event simulation-based finite-capacity model, as a tool for scheduling equipment and personnel. A sample manufacturing system is used to illustrate both the issues to be considered and techniques used in scheduling a factory.
