OPMA 3306 - EXAM 2 QUESTIONS
AND ANSWERS
Production Process - Correct Answers -Used to make any manufactured item
Step 1- Source the parts needed
Step 2- Make the product
Step 3- Deliver the product
Lead Time - Correct Answers -The time needed to respond to a customer order
Customer Order Decoupling Point - Correct Answers -Where inventory is positioned to
allow entities in the supply chain to operate independently
Workcenter (Job Shop) - Correct Answers -Similar equipment or functions are grouped
together
Manufacturing Cell (Cellular) - Correct Answers -A dedicated area where products that
are similar in processing requirements are produced
Lean Manufacturing - Correct Answers -A means of achieving high levels of customer
service with minimal inventory investment
Types of Firms - Correct Answers -1. Make-to-Stock
2. Assemble-to-Order
3. Make-to-Order
4. Engineer-to-Order
Make-to-Stock - Correct Answers -Serve customers from finished goods inventory
Televisions, clothing, packaged food products
Essential issue in satisfying customers is to balance the level of inventory against the
level of customer service (easy with unlimited inventory but inventory costs money;
trade-off between the cost of inventory and level of customer service must be made)
Use lean manufacturing to achieve higher service levels for a given inventory
investment
Assemble-to-Order - Correct Answers -Combine a number of preassembled modules to
meet a customer's specifications
, A primary task is to define a customer's order in terms of alternative components since
these are carried in inventory
One capability required is a design that enables as much flexibility as possible in
combining components
Make-to-Order - Correct Answers -Make the customer's product from raw materials,
parts, and components
Customer order decoupling point could be in either raw materials at the manufacturing
site or the supplier inventory
Depending on how similar the products are, it might not even be possible to pre-order
parts
Engineer-to-Order - Correct Answers -Work with the customer to design and then make
the product
Boeing's process for making commercial aircraft
Customer order decoupling point could be in either raw materials at the manufacturing
site or the supplier inventory
Depending on how similar the products are, it might not even be possible to pre-order
parts
Production Process Mapping - Correct Answers -Develop a high-level map of a supply
chain process
Useful to understand how material flows and where inventory is held
First step in analyzing the flow of material through a production process
Little's Law - Correct Answers -The flow of items through a production process can be
described through this
Inventory = (Throughput Rate)(Flow Time)
Throughput- Long term average rate of flow through the process
Flow Time- Time for a single unit to traverse the entire process
Inventory- Materials held by the firm for future use
