Explore capacity adjustment strategies to meet forecasted demand through regular time, overtime, hiring, subcontracting, or back ordering, considering costs and capacity constraints to minimize annual production costs.
Level production maintains uniform output year-round, using inventory from lean periods to meet variable demand.
Chasing demand aligns production with changing demand over time, producing more when demand rises and less when it falls. Minimize inventory focus while satisfying demand through timely production.
Apply quantitative techniques to minimize total production cost using unit costs, capacity constraints, and demand data. Explore pure and mixed strategies, including linear programming and transportation methods, for production planning.
Level production strategy ensures producing 100,000 per quarter for a 400,000 annual demand, using inventory to balance quarterly gaps and totaling 870,000 in annual costs.

Explore mixed strategies in production planning, combining level production and chase demand, while managing capacity constraints, inventory limits, layoffs, and vacations during low demand.
Learn how capacity is defined as output rate and key resources per period, and how to plan and optimize utilization to meet forecasted demand.
Execute strategic capacity planning by evaluating facilities, equipment, and labor, using capacity utilization and ROI to align with demand. Decide when to increase or reduce capacity based on market demand.
Calculate capacity utilization rate as capacity used divided by the best operating level, the nominal capacity a process is designed for, illustrated with 100 kg vs 70 kg.

Define and apply the best operating level to balance capacity and planning, maximizing output while minimizing wear, with an analogy of engines, assembly lines, and driving range for fuel efficiency.
The average unit cost of output varies with production volume, rising at low volumes, optimizing around 500 soap cakes, and increasing at high volumes due to machine wear and maintenance.
Learn how economies of scale reduce cost per unit as output grows, and how diseconomies raise costs at higher volumes, noting the best operating level to minimize average cost.
Explore economies of scale and diseconomies of scale, identify the best operating level at around 300 units, and analyze how capacity planning affects average unit cost.
Explore how economies of scale lower cost per unit as output grows by spreading fixed costs, boosting efficiency, and utilizing bulk discounts, until diseconomies emerge at the best operating level.
Explore how diseconomies of scale arise from distribution, bureaucracy, confusion, and vulnerability, leading to chaotic operations, underutilized capacity, and poor planning due to management complexity.
Compute capacity utilization by dividing capacity used by operating level. With 83 units vs 120, rate is about 0.69 (70%), revealing unused capacity and opportunities to improve efficiency and productivity.
Determine capacity requirements through forecasting sales and calculating machine and labor needs, balancing regular and overtime production, and options for outsourcing to maintain line balance and meet demand.
Determine capacity requirements from demand forecasts, develop and evaluate alternatives (including outsourcing), select and implement the optimum capacity development plan.
Map four-year demand forecasts to machine and labor capacity for small and family size mustard bottles, calculate utilization, and determine required machines and operators for production planning and control.
The Production Planning and Control (PPC) course offers an in-depth exploration of the essential principles and practices used to ensure efficient and effective production processes in both manufacturing and service organizations. The course begins with an introduction to PPC, covering its fundamental concepts, definitions, and the critical objectives it aims to achieve. Students will learn about the primary functions of PPC, the various levels at which PPC operates, and the significant benefits and limitations associated with its implementation.
The course then delves into process planning, highlighting the factors that influence it and the methods used to carry it out effectively. Students will gain insights into product realization and will learn to determine machine requirements, including detailed examples and calculations to illustrate these concepts practically.
Aggregate planning forms a crucial part of this course. Students will be introduced to the objectives of aggregate production planning (APP) and the comprehensive process involved. The course will explore different strategies for meeting demand, including level capacity and chase demand strategies. Quantitative techniques for APP will be discussed, along with examples of pure strategies, level production strategies, chase demand strategies, and mixed strategies.
The course also covers capacity planning, focusing on strategic capacity planning and the importance of capacity utilization rate. Students will learn about capacity decisions, the impact of capacity utilization on capacity requirements, and the importance of accurate capacity planning. Measuring capacity, determining the best operating level, and understanding the average unit cost of output will be covered, with specific examples such as the best operating level for a hotel.
Additionally, the course will address the concepts of economies and diseconomies of scale, using examples and graphs to illustrate these ideas. Students will explore how economies of scale and operating level curves affect production efficiency and will examine the phenomena of diseconomies of scale and confusion. Practical examples of capacity utilization and steps in capacity planning will provide students with a robust understanding of determining capacity requirements. Finally there are 50 numerical exercises to practise on different scenarios.
By the end of this course, students will be equipped with the knowledge and skills to effectively plan and control production processes, apply process planning methods, implement aggregate planning strategies, conduct strategic capacity planning, and analyze the impact of economies and diseconomies of scale. Assessment methods will include quizzes, assignments, case studies, practical examples, and exams to ensure a comprehensive understanding of PPC principles and their application in real-world scenarios. This course is ideal for students and professionals in operations management, manufacturing, and related fields looking to enhance their expertise in production planning and control.
