Production Planning and Control
What is Production Planning and Control?
The process of determining the production goals and the resources required to achieve them.
Key formula / rule: Economic Production Quantity (EPQ)
Key points
- Understand the objectives and scope of PPC.
- Identify and apply different planning and scheduling techniques.
- Analyze production capacity and resource requirements.
- Implement control measures to monitor and improve production.
Common exam trap
Inaccurate demand forecasting leading to overproduction or shortages.

Formulae
- Name
Economic Production Quantity (EPQ)
- Note
D = Annual demand, S = Setup cost per order, H = Holding cost per unit per year. Used for determining optimal production batch size.
- Expression
EPQ = sqrt((2 * D * S) / H)
- Name
Production Rate
- Note
Measures the output of a production process over a given period.
- Expression
Production Rate = (Units Produced) / (Time Taken)
- Name
Machine Utilization
- Note
Measures the efficiency of a machine's operation.
- Expression
Machine Utilization = (Available Production Time - Downtime) / Available Production Time
Prerequisites
Operations Management

Inventory Management Concepts
Forecasting Techniques
Common mistakes
Inaccurate demand forecasting leading to overproduction or shortages.
Underestimating resource availability or capacity constraints.
Poorly defined production schedules with unrealistic timelines.
Lack of effective monitoring and control mechanisms.
Failure to adapt to changes in demand or production conditions.
Ignoring inventory management, leading to excessive or insufficient stock.
