1. Decision Making Concepts
(a) What makes decisions hard?
(b) In class we addressed different approaches to multi-criteria decision making. Briefly explain two different approaches to decision making when there are multiple criteria to be considered.
2.Manufacturing and Service Systems
In class (and on the slides) we defined different classifications for service systems and discussed key differences between products and services and how these differences affect the system development life cycle for services
(a) List and describe the three service system classifications and give an example of each.
(b) What are some of the key differences between services and manufacturing and how do these differences affect the systems development life cycle for service systems (vs. that for products/manufacturing)
(c) List and define/describe the basic types of manufacturing process flows and give an example of each.
(d) Sketch and label the process-product matrix. What does this process-product matrix tell us?
3.Queueing Concepts
(a) What is the basic economic tradeoff one is trying to achieve in a queueing system?
(b) Why must m be greater than l for the M/M/1 queue?
(c) What is a key advantage of an M/D/1 queue vs. an M/M/1 queue?
(d) Provide and explain/describe an example (i.e. a real physical situation) of a M/M/k/k queueing system.
(e) List three different types of queue disciplines and give an example where you might find each discipline
(f) Customers generally find waiting in line to be an unpleasant experience. In addition to reducing the length of the wait itself, what other steps could a business take to reduce the frustration customers experience while waiting? Give at least four specific examples.
