The planning and control of Production (PPC)

In general, the production planning and control can be defined as the activities plan and control incoming material, process, and out of the system of production so that demand can be met by the right amount, time of submission the right and the minimum production cost.

Whereas if we define separately the two activities will include:

#1. Production planning is an activity to assign a product to be produced, the amount required, when such products have to be completed and the required resources.

#2. Production control is the activities that establish the ability of the resources used in fulfilling the plans, production capacity going according to plan and do a repair plan.
As for the purpose of planning and control of production are:

  1. It so that companies can produce effectively and efficiently.

  2. Dress it so that the company can use the capital optimal as possible.

  3. The dress it up so the factory can master a broad market.

  4. to obtain a sufficient profit for the company.

  5. Predict product demand expressed in number of products as a function of time.

  6. Monitor the actual permitting, comparing it to the previous demand forecast and do revision of the forecasts in case of irregularities.

  7. Set the size of the reservation goods economically upon the raw materials will be purchased.

  8. establish an economical supply system.

  9. Set the production needs and the level of inventory at any given moment.

  10. Monitor inventory levels, comparing it to the plan preparation, and do production plan revisions at the time specified.

  11. Make a production schedule, assignments, as well as the imposition of a machine and a detailed labor.

The level of planning and controlling production:

Long-term planning

This activity includes forecasting planning efforts, the number of products and sales, production planning, raw material requirements planning, and financial planning.

Medium-term Planning

This activity includes planning capacity needs, planning of material needs, schedule production, and stem planning needs distribution.

Short term Planning

These activities include scheduling the final product Assembly, planning and control of input-output, production control, purchase planning and control, and project management.

Planning and controlling production does is include some of the following activities:

  1. Forecasting demand quantity.

  2. Inventory Planning: the type, amount, and time.

  3. Capacity planning, drafting plans for aggregates, labor, machinery, facilities for the adjustment of demand with capacity. The aggregate plan aims to make the work of loading scenarios to the engine and power (regular, overtime, subcontracting) optimally to the overall product and resources are integrated.

  4. Make the parent schedule production (JEEP). A detailed plan is the JEEP on "what and how many units" that have to be produced in a given period for the production of each item. JEEP made (one of them) broke (dis aggregate) plan the aggregate into the production plan (what, when and how) that will be realized.

  5. purchasing/procurement Planning: types, amount and time.

  6. Scheduling of machines and production facilities. This includes scheduling the sequence of the work, the time of completion of the order, the priorities of the workmanship, and so on.

  7. Monitoring activities of production.

  8. Reporting and logging.

Classification of Production Systems

Based on the type of production, the production system can be group into four, namely:

  1. Engineering to Order (ETO). The production system is complete when the customer asks manufacturers. To make products that start from the process.

  2. Assemble to Order (ATO). The production system is complete when a manufacturer makes a standard design made up of several components and assemble a certain combination of these components in accordance with the order of the consumer. Standard components are usually assemble for various types of products. An example is a car company, where they provide the option to manually/automatic transmission, air conditioning, audio, interior, and engine. The component has been prepared since the beginning and will be assemble into the car intact so there is an order of the Agency.

  3. Make to Order (MTO). The production system is complete when manufacturers make a product (producing). "If and only if" has been taking orders from consumers for the product.

  4. Make to Stock (MTS). The production system is complete when manufacturers make (produce) product as an inventory before an order is receive from the consumer.
