Exam 1 Flashcards
5 Production System Design - Project Layout
based on type of product being made:
- large heave products
-remain in fixed location
5 Production System Design - Continuous Layout
Based on product being made:
- for liquid products
5 Production System Design - Assembly line
-standard items are produced through a fixed sequence of workstations
- designed to achieve high volume
5 Production System Design - Manufacturing Cell Layout
A dedicated area where products that are similar in process requirements are produced
5 Production System Design - Work-center or Job Shop
- each department is focused on particular operation
useful when each product is unique - high flexibility
Make to stock
product environment where customer is served “on demand” from finished goods inventory
least customization, short lead time
Assemble to Order
Preassembled components are put together in response to a specific
customer order
-little customizations, short lead time
Make-to-Order
The product is built directly from raw materials and components in response
to a specific customer order
lead time will be longer, more costly
Engineer to Order
Firm works with the customer to design and then make the product
lead time will be longer, more costly
What is Assembly line balancing
process of assigning tasks to workstations
goal: minimize idle time along the line
what does workstation cycle time represent
represents the upper limit for processing time at any workstation
what does N(a) symbolize
theoretical minimum workstations
What are the three steps for assigning tasks
1.) consider only tasks that have all predecessors assigned
2.) from the tasks with all their predecessors assigned, consider only tasks that won’t exceed the required cycle time
3.) if more than one task meets use rule
what does littles law describe
the flow of items through a production process
Spot Purchase
a one time purchase
electronic catalog
provides information on services and/or products offered by a vendor or service provider
- used for repetitive purchasing
Request for Bid
a company interested in procurement of a product or service request the price from multiple providors
-used for well defined products
Request for proposal

-used when the supplier is better positioned than the buyer to decide where inventory should be held
-ex: hallmark cards in Walgreens
Strategic alliance
an agreement between two or more parties to pursue a set of agreed upon objectives while remaining undefended organizations
Specificity
how common items are
high specificity
very specific, not common
low specificity
common items not very specific
What is the bullwhip affect
a slight change in consumer sales ripples backwards and magnifies as it gets back to supplier
