Production Planning And Control

Production Plan• Production planning involves management decisions on the resources that the firm will require for its

manufacturing operations and the selection of these resources to produce the desired goods at the appropriate

time and at the least possible cost

• Production planning is dynamic in nature and always remains in fluid state as plans may need to be change.

Material Requirements PlanningMaterials requirements planning (MRP) is a computerized inventory planning and control system for determining when (no earlier and no later) and how many of each of the parts, components, and materials should be ordered or produced.

The basic idea is to get the right materials to the right place at the right time.

Loading & Scheduling :

Loading is the assignment of Work to the workers and equipment.

Scheduling involves fixing the priorities for different jobs and deciding the starting and finishing time (or

date) of each job. Also called as time based loading.
