ADVANCED MANUFACTURING SYSTEMS DESIGN Week 9 Discussion Midterm Exam Slide 2 © 1999 John ADVANCED MANUFACTURING SYSTEMS DESIGN Week 9 Discussion Midterm Exam Slide 2 © 1999 John W. Nazemetz

Question 1 1 (25 pts. ) Comprehensively define and briefly discuss the broad definition Question 1 1 (25 pts. ) Comprehensively define and briefly discuss the broad definition of product life cycle and the CIM environment discussed in this class. Be sure to discuss the intersection of the life cycles of product and production facilities. Slide 3 Computer Integrated Manufacturing Systems © 1999 John W. Nazemetz

Question 1 -- Response • Expectation – Discussion of Product Life Cycle Model of Question 1 -- Response • Expectation – Discussion of Product Life Cycle Model of Design, Produce, Operate, Support, Dispose • Discuss/Define Each Phase of the cycle and the associated CIM activities in each phase. • Thought many/most students would use the Chris Vaughn model as the basis upon which the answer was developed, especially to illustrate the intersection of product and production facility life cycles – Most did not.
