Exam 1 Flashcards
A good planning system must answer four questions…
- what are we going to make or provide to customers?
- What does it take to make it?
- What do we have?
- What do we need?
Priority?
relates to what products are needed, how many are needed, and when they are needed.
- Marketplace establishes priority.
- Manufacturing is responsible for devising plans to satisfy the market demand if possible.
Capacity
the capability of manufacturing to produce goods and services.
- Depends on the resources of the company.
- In the short term, capacity is the quantity of work that labor and equipment can perform in a given period.
Five major levels of the manuf. planning and control system?
Strategic business plan
Production Plan (sales and operation plan)
Master production plan
Material requirements plan
Purchasing and production activity control
Order Winners (OW)
- Provide competitive advantage
- Different in different markets
- Change over time
- Those characteristics that persuade customers to select a product or service.
Order Qualifiers (OQ)
- Allow organization to compete in the marketplace
- Does not actually help with orders/sales
- Ex: Car Warranty
- Customer requirements for price, quantity, and delivery.
“Todays order winners are tomorrow’s Qualifiers”

ETO
- Manufacturer does not start until order is received
- Long Lead time
- Unique/Custom Products
MTO
- Manufacturer does not start until order is received
- Uses standard components
- Little design time
- Inventory held as raw materials
ATO
- Manufacturer inventories standard components
- No design time
- Only assembly
- Shorter lead time/Inventory held as raw materials
MTS
- Manufacturers produce the goods in anticipation of customer demand
- Little customer involvement in design
- Shortest lead time
- Inventory held as finished goods
Main objectives for companies in traditional systems?
- Best customer service
- Lowest production costs
- Lowest inventory investment
- Lowest distribution costs
Materials management
- Planning and controlling the flows of materials
- maximize the use of firm resources
- provide the level of required customer service>
- by production planning, implementation and control, and inventory management.
Production Planning
Meet demands in the marketplace, to ensure capacity
- Forecasting
- Master planning
- materials requirements planning
- Capacity planning
Implementation and control
- Putting into action and achieving plans
- Production activity control
- Purchasing
Inventory Management
- To support production (RM) or as a result of production (FG)
- Provides a buffer against differences in demand rules and production rates.
Inputs to Mfg Plan + CS
- Product description
- Process specifications
- Time needed
- Available facilities
5 Quantity required
Enterprise Resource Planning (ERP)
Gives companies the ability to link electronically, sharing large amounts of information.
MPC System
- its a hierarchy
- flows downward
- Richer as it goes down
Resource Planning (Capacity)
Demands lead to resource planning
Demand Management (Priority)
Every level of MPC system must check resource planning + demand management.
Strategic Business plan

- Low level of detail
- 6 months to a year planning cycle
Production plan or sales and operations planning
- 6-18 months
- Satisfy market demand with available resources
- Low level of detail (Product families or groups)
- Monthly or quarterly planning cycle
Master Production Schedule
- 3-18 months, but LT dependent
- Production of individual end items
- Higher individual end items
- Weekly or monthly planning cycle
Materials Requirement planning
- LT driven = 3-18 months
- Component planning, quantities and when needed
- High level of detail
- Weekly planning cycle
Production Activity control or Shop Floor Control
- 1 day to 1 month
- Implementation and control of flow
- High individual components, work orders, work stations
- Daily planning cycle
Sales and operation planning qualities
- Not static
- Have to review/update
- Cross functional
- High up in org
Product groups or families
Based on similar units of measure or similar manufacturing process.
