Control is a general management function which can be described as the constraining of events to follow plans. It involves setting standard or plans, monitoring performance and company results against plan of standards and correctly deviations from plans or standards when necessary.
Production control can therefore be described as a function of management which plans, direct and controls the material supply and processing activity of an enterprise. As Mayers puts it in his book, Production Management, that production control involves the development and implementation of a plan, which is capable of yielding the desired results. In his book Principle of Production Control as a function of management which plans directs and controls the material supply and processing of activities of any enterprise so that the specified methods to meet an approved sales programme can be achieved.
OBJECTIVE OF PRODUCTION CONTROL
The following may be considered simultaneously as the major objectives of production control:
To ensure timely delivery of output
To meet the targeted output
To minimize waste
To improve quality through reduction in lower-time reduction in ship floor labour etc.
To improve cash flow by reducing work-in-process, raw materials, stock and finished goods stock
To minimize industrial relations problems
The achievement of one of these could be at the expense of others.
For example, the majority of others could be produced on time but this could lead to minimal order batching, which in turn will increase production cost.
More finished goods stock could help batching but cash flow will deteriorate.
It is therefore important the production and other be able to calculate the advantages of the objective that must be aware of the need to consider trade-off and have the information with which to do it.
The objectives of a production control system will help to determine:
(Imaga E.U.C. Theory and Practice of Production Management).
The type of system required. For example, if organization is dominated by need to provide flexibility and a speedy response to customer demands, then production control system must have flexibility as an overriding design consideration.
The data needed. Judging by the relative merit of undertaking, one opposed to other course of action and deciding upon other sequencing rules on which production scheduling is based, required appropriate data.
How the system is operated. For example, a manual system will have a limited capacity to handle large quantities of information. It ,ay be restricted also to providing sufficient flexibility.
The degree of inter-relationship needed within the productive control and system. Links between inventory control and production planning can be strong and weak depending upon the importance of en-stock deliveries.
Generally, production control has made an impressive impact in solving many recurring production problems and scheduling activist, so as to know the types of raw material to supply all aiming at reducing the costs of the entire production it can be reviewed as a management tool and an analytical process that offer many advantages to the production system.

PRODUCTION CONTROL SYSTEM
Production control system is largely determined by the type of production process being controlled (i.e job, batch, flow or continuous) the choice of a production as::
Production types and its characteristics
Demand of the project whether big or small, regular or occasional.
What processes are involved, such things are the degree of standardization possible and qualities and workmanship required.
