Spanning months to a year, this level translates strategic goals into actionable plans. The primary tool here is the Master Production Schedule (MPS). The MPS specifies what end items are to be produced, in what quantities, and when. Material Requirements Planning (MRP) systems operate at this level, breaking down the MPS into component requirements based on Bills of Materials (BOM).
The continuous tracking of actual production metrics against the planned schedule. Control teams log machine uptime, labor efficiency, and material consumption rates.
Production Planning and Control (PPC) is the process of planning, scheduling, and managing the entire production process to ensure the efficient utilization of resources. It acts as the brain of the factory, translating sales forecasts and orders into specific, actionable manufacturing schedules.
Maximizing the utilization of machinery, tool wear, and labor schedules to reduce idle times.
The reactive, real-time stage. It oversees shop-floor execution. Control mechanisms compare actual output against the planned timeline, stepping in to correct bottlenecks, machine failures, or material shortages. the fundamentals of production planning and control pdf
Forward scheduling calculates the earliest possible completion date based on today's available resources. Backward scheduling starts from the customer's due date and works in reverse to find the latest acceptable start date. 3. Dispatching
Intervening when a machine breaks down or a process runs slower than scheduled to reroute work and get back on track. Essential Production Planning Strategies
: Identical items produced in groups (e.g., bakeries, pharmaceuticals).
The complete execution of a PPC system relies on four sequential phases. Each stage builds on the information gathered in the previous step. Spanning months to a year, this level translates
Some best practices in production planning and control include:
Expediting is the control phase where actual output is continuously monitored against the timeline. If machine breakdowns or material shortages cause delays, the expediting team steps in to reroute work or authorize overtime to keep schedules on track. 4. Key Elements of Successful Production Planning
The Fundamentals of Production Planning and Control (Stephen N. Chapman)
High variety in product offerings makes scheduling difficult. Material Requirements Planning (MRP) systems operate at this
PPC consists of two key functions: (forecasting, scheduling, and material requirement planning) and Production Control (monitoring progress and taking corrective actions).The process generally follows a three-stage lifecycle:
Planning, purchasing, and controlling materials from raw to finished goods.
Routing defines the path a product takes through the factory. It specifies the sequence of operations, the machines or workstations to be used, the required tools, and standard times for each step. A route sheet is the tangible output, serving as a navigational map for production. Without accurate routing, scheduling is arbitrary and material flow becomes chaotic.
