Scheduling is a method of determining the quantity and timing of production over a specified period of time. Scheduling is the process of arranging, controlling and optimizing work and workloads in a production process or manufacturing process. First-come-first-served scheduling (FCFS) establishes a fair order, based on estimated times of arrival, and determines proper separations. Classify production systems as shops based on the arrangement of machines? It does not lower cost, improve quality or assure faster and dependable delivery.
