Production planning and control can be viewed as the nervous system of the production operation. This function aims at efficient utilization of material resources, people and facilities in any undertaking through planning, coordination and controlling the production activities that transform the raw material into finished products or components as a most optimal manner.

Routing is the first but the most important and difficult task of the production control. Routing means, determination of path or route on which manufacturing operations will travel, establishing the sequence of operations manufacturing a particular product. According to Kimball and Kimball, It is selection of path or route over which each piece is to travel in being transformed from raw material into finished product . to be followed in

Objectives Determining the most feasible sequence of operations and ensuring that this sequence must be followed Utilizing the physical human resources, materials and machines employed in the production to the best Exercising the influence upon the design of the factory building and the machines II.Advantages Efficient use of available resource Reduction in manufacturing costs Improvement in quantity and quality of the output Provides a basis for scheduling and loading a. b. c. a. b. c. d.
Scheduling may be defined as the assignment of work to the plant with the specification of times and the sequence in which the work is to be the specification of times, and the sequence in which the work is to be done. According to Spriegal and Lansburgh, scheduling involves establishing the amount of work to be done and the time when each element of work will start or order of work.
Scheduling aims to achieve the required rate of output with a minimum of delay, and disruption in processing To provide quantities of goods necessary to maintain finished inventories at levels predetermined to meet delivery commitment The aim of loading and scheduling is to have maximum utilization of men, machines maintaining a free flow of materials along the production line To keep the production cost minimum To prevent unbalanced allocation production departments with a view to eliminate idle capacity. and materials by of time among
