Production planning is the planning of production and manufacturing modules in a company or industry. It utilizes the resource allocation of activities of employees, materials and production capacity , in order to serve different customers.
Different types of production methods, such as single item manufacturing, batch production , mass production , continuous production etc. Production planning can be combined with production control into production planning and control, or it can be combined with enterprise resource planning. Production planning is the future of production. It can help in efficient manufacturing or setting up of a production site by facilitating required needs. It can comprise the following activities:. In order to develop production plans, the production planner or production planning department needs to work closely together with the marketing department and sales department.
They can provide sales forecasts, or a listing of customer orders. Therefore, the selection must optimize customer-independent performance measures such as cycle time and customer-dependent performance measures such as on-time delivery.
A critical factor in production planning is "the accurate estimation of the productive capacity of available resources, yet this is one of the most difficult tasks to perform well". Modern production planning methods and tools have been developed since late 19th century. Under Scientific Management , the work for each man or each machine is mapped out in advance see image.
The origin of production planning back goes another century. Kaplan summarized that "the demand for information for internal planning and control apparently arose in the first half of the 19th century when firms, such as textile mills and railroads, had to devise internal administrative procedures to coordinate the multiple processes involved in the performance of the basic activity the conversion of raw materials into finished goods by textile mills, the transportation of passengers and freight by the railroads.
Herrmann further describes the circumstances in which new methods for internal planning and control evolved: "The first factories were quite simple and relatively small. They produced a small number of products in large batches.
Productivity gains came from using interchangeable parts to eliminate time-consuming fitting operations. Through the late s, manufacturing firms were concerned with maximizing the productivity of the expensive equipment in the factory.
Keeping utilization high was an important objective. Foremen ruled their shops, coordinating all of the activities needed for the limited number of products for which they were responsible. They hired operators, purchased materials, managed production, and delivered the product. They were experts with superior technical skills, and they not a separate staff of clerks planned production.
Even as factories grew, they were just bigger, not more complex. About production planning Herrmann recounts that "production scheduling started simply also. Schedules, when used at all, listed only when work on an order should begin or when the order is due. They didn't provide any information about how long the total order should take or about the time required for individual operations In Industrial Management cited a Mr.
Owens who had observed: "Production planning is rapidly becoming one of the most vital necessities of management. It is true that every establishment, no matter how large or how small has production planning in some form; but a large percentage of these do not have planning that makes for an even flow of material, and a minimum amount of money tied up in inventories.
Production control is the activity of controlling the workflow in the production. It is partly complementary to production planning. From Wikipedia, the free encyclopedia.

By PlanetTogether. Throughout the years, manufacturers have been on a quest to improve their operations by increasing productivity, managing their inventory , and optimizing their resource utilization. These are some of the main challenges faced by manufacturers. Many strategies have emerged as solutions to allow manufacturing operations to improve their overall production efficiency. One such strategy is Production Planning and Control PPC , which is a term used to describe two essential components of manufacturing: production planning and production control. The production planning portion handles the activities necessary before production actually begins, such as materials planning, capacity planning, and operations scheduling.
The manager who moves from manufacturing to services or the professor who wishes to research and teach service operations must recognise the key differences for developing an appropriate operations management strategy in a service business. For this process to be successful, the operations manager must participate assertively in the strategy debate. What little buffering there is occurs between the front office and the back room. This article outlines and contrasts the processes for both manufacturing and services, paralleling the models of Wheelwright and Hayes and Hill. The observed process differences have major implications for both teaching and research in service operations.
Types Of Planning Pdf Types of plans are- Operational, tactical and strategic plan, formal and informal plan, proactive and reactive plan and functional and corporative plan. Construction planning is a fundamental and challenging activity in the management and execution of construction projects. The last section of the statement of work is the risk plan.

For efficient, effective and economical operation in a manufacturing unit of an organization, it is essential to integrate the production planning and control system. Production planning and subsequent production control follow adaption of product design and finalization of a production process. Production planning and control address a fundamental problem of low productivity, inventory management and resource utilization. Production planning is required for scheduling, dispatch, inspection, quality management, inventory management, supply management and equipment management. Production control ensures that production team can achieve required production target, optimum utilization of resources, quality management and cost savings. Planning and control are an essential ingredient for success of an operation unit. The benefits of production planning and control are as follows:.
