Whether you are planning a meal for some friends or a holiday trip, having a schedule in place is essential. Same is true for a job shop production. Essentially, the goal is to match supply and demand. On the one side, supply includes the capacities, resources, labor and the available material in the job shop. On the other side, the demand encompasses the actual job orders including the according resources and capacities needed to complete the job. Job shop scheduling aims to combine these two components, internal supply and demand, in the most optimal way possible. Therefore, having a proper schedule in place is a crucial value proposition for job shop managers.
