- Project Manufacturing
- Repetitive Manufacturing
- Flexible Manufacturing
- Capacity Considerations
- Planning and Scheduling
- Incorporates demand management strategies
Types of Mnufacturing Operations
Operation in which short production runs are used to produce small quantities of items.
Job Shop
Operations used to create unique but similar items.
Project Manufacturing
Operations in which long production runs are used to produce a large quantity of standardized product.
Repetitive Manufacturing
Operations that usually involve computer- controlled equipment that can turn out products in smaller or more flexible quantities.
Flexible Manufacturing
- Capacity limits a firm’s ability to meet demand.
- Capacity determines startup (fixed) costs.
- Ability to adjust capacity differs among firms.
Capacity Considerations
- Involves attempting to achieve the orderly, sequential flow of products or services to market.
- Is critical in service industry operations.
Planning and Scheduling
Strategies to stimulate customer demand when it is normally low.

Inventory Management and Operations
- Ensuring continuous operations
- Maximizing sales
- Protecting assets
- Optimizing inventory investment
Objectives of Inventory Management
To support customer demand and balance sheet concerns is critical for a healthy business.
Balancing Inventory
The quantity to purchase in order to minimize total inventory costs.
- Total Inventory Costs = Total Carrying Costs + total Ordering Costs
Economic Order Quantity (EOQ) - inventory cost control
A system of classifying items in inventory by relative value.
- Category A (close/continuous control)
- Category B (moderate control)
- Category C (periodic control)
ABC Inventory Classification
High-value or critical production component items.
Category A (Close/Continuous Control)
Less costly, secondary importance items.
Category B (Moderate Control)
Low-cost and noncritical items.
Category C (Periodic Control)
A demand (pull) method of reducing inventory to an absolute minimum.
- New inventory items arrive at the same time that the last inventory item is placed in service.
Just in Time Inventory (JIT) System
- Closer coordination with suppliers
- Consistent quality production
- Lower safety stock levels
JIT Promotes:
- Physical inventory system
- Cycle counting
- Perpetual inventory
- Two-bin inventory system
Inventory Record-Keeping System
Provides for periodic counting of items in inventory.
