📦 Operations Management Unit 4 – Capacity Planning and Facility DesignCapacity planning and facility design are crucial aspects of operations management. These processes involve determining production capacity, optimizing resource utilization, and creating efficient layouts to meet customer demands and improve overall performance.
Key concepts include capacity, utilization, efficiency, and bottlenecks. Strategies range from lead and lag approaches to match and adjustment tactics. Facility location and layout decisions consider factors like proximity to stakeholders, transportation access, and workflow optimization.
Key Concepts and Definitions
Capacity planning involves determining the production capacity needed by an organization to meet changing demands for its products
Capacity the maximum amount of work that an organization is capable of completing in a given period of time
Utilization the extent to which an organization's capacity is being used in a given period
Efficiency a metric that measures the performance of a process, expressed as the ratio of useful output to total input
Bottleneck a point of congestion in a production system that occurs when workloads arrive at a point more quickly than that point can handle them
Lead time the total time a customer must wait to receive a product after placing an order
Takt time the maximum amount of time in which a product needs to be produced in order to satisfy customer demand
Importance of Capacity Planning
Ensures that an organization can satisfy its customers' demands in a timely manner
Prevents bottlenecks and delays in production or service delivery
Helps optimize resource utilization and minimize waste
Enables an organization to adapt to changes in demand
Seasonal fluctuations (holiday shopping season)
Market trends (shift towards online shopping)
Supports long-term strategic planning and decision making
Reduces the risk of capacity-related issues
Stockouts
Excessive inventory
Overworked employees
Contributes to improved efficiency and profitability
Capacity Planning Strategies
Lead strategy adding capacity in anticipation of an increase in demand
Lag strategy adding capacity only after an organization is running at full capacity or beyond due to increased demand
Match strategy adding or reducing capacity incrementally in response to changing demand in the market
Adjustment strategies for modifying capacity
Utilizing overtime
Adding shifts
Outsourcing production
Hiring temporary workers
Factors influencing the choice of strategy
Demand predictability
Capacity flexibility
Cost considerations
Risk tolerance
Facility Location Decisions
Proximity to suppliers, customers, and other key stakeholders
Access to transportation networks (highways, ports, airports)
Availability and cost of labor
Local regulations and tax incentives
Environmental factors (climate, natural disaster risk)
Potential for future expansion
Political stability and economic conditions
Alignment with overall business strategy
Facility Layout Design
Process layout arranging resources around processes, suitable for low-volume, high-variety production
Product layout arranging resources in a line, suitable for high-volume, low-variety production
Cellular layout combining the benefits of process and product layouts, suitable for medium-volume, medium-variety production
Fixed-position layout resources are brought to a fixed location, suitable for large, complex projects (aircraft assembly)
Factors influencing layout decisions
Material flow
Equipment utilization
Flexibility for future changes
Ergonomics and safety
Systematic Layout Planning (SLP) a step-by-step approach to designing facility layouts
Capacity planning software for demand forecasting and capacity optimization
Simulation modeling to analyze complex systems and test "what-if" scenarios
