Steps in Production Planning

• PPC(Production Planning and control):

Any activity whose success is dependent on the coordination and cooperation of many people will benefit from careful planning and control, and the manufacturing environment requires the interaction of many people and machines

The first step in planning of any type is to identify the goals you wish to achieve.

There are several steps have a traditional set of names.

1. Process planning (routing) determines the sequence of operations needed to produce the product.
2. Loading sets aside the necessary time on each machine or workstation to process the desired quantity.
3. Scheduling establishes when each step of the work will be performed.
4. Dispatching is the official authorization to do the work.

production control is the system whereby deviations from the planned schedule are reported to the production planning and control office (#ppc ) so that schedule adjustments can be made.

• Production Planning and Control Systems:

Materials requirements planning (MRP) refers to a set of time-phased order-point techniques to support manufacturing schedules. #mrp began development in the 1950s as the cost of computer calculation began to decrease. At its simplest, it provides a schedule for ordering raw material and parts and performing production operations to provide the products of production (end items) on time.

MRP begins with a master production schedule (#mps ) that identifies when end items must be available to meet customer or other commitments.

• Lean Manufacturing:

This system was developed between 1948 and about 1975 in Japan as Toyota was returning to the production process following World War II. As the system spread, the name changed several times from #tps to (now) #leanmanufacturing Manufacturing. The main goal of TPS is to eliminate waste (muda). There are seven

kinds of waste targeted in TPS:

defects,

overproduction,

transportation,

waiting,

inventory,

motion

over processing.

The key Lean Manufacturing principles are as follows:

• Perfect first-time quality.
• Waste minimization.
• Continuous improvement.
• Pull processing.
• Flexibility.
• Building and maintaining a long-term relationship with suppliers
