NazemetzSlide 7 Computer Integrated Manufacturing Systems Mid-Term Exam Campus – Instructor will Administer During Regular Class Time (10/11) Off-Campus – If Site Coordinator is Available, All Students at Site to arrange schedule with coordinator. Coordinator will monitor exam. Off-Off Campus – Student will arrange time during business hours to begin exam with Trefny Chelesvig (405-744-0359). She will fax exam to you at start time. You must fax back within 2.5 hours. Exam to be taken between 10/11 and 10/17 {Prefer 10/11-12 so can return before discussion on 10/18}

11. © 2000 John W. NazemetzSlide 11 Computer Integrated Manufacturing Systems Discussion Questions During Concurrent Engineering there does not seem to be any consideration for the loading on the manufacturing/fabrication equipment necessary to produce the desired part or product. Should not this be considered? If equipment will be loaded 3/7 with out allowance for everyday maintenance and necessary rebuilds required after a given numbers of hours of operation, are you not planning to fail. I find at York they do not seem to be concerned with the maintenance requirements, just the production capabilities. There are many other aspects of this which are of concern.During Concurrent Engineering there does not seem to be any consideration for the loading on the manufacturing/fabrication equipment necessary to produce the desired part or product.

12. © 2000 John W. NazemetzSlide 12 Computer Integrated Manufacturing Systems Discussion Questions In the material covered in CAPP, the text raises the subject of setup time being in the calculations for piece cost. They do not discuss the subject of operator maintenance which maybe required after every part or a certain number of parts. This type of operator maintenance is required to assure consistent parts and reduced unaccounted for downtime on production/fabrication equipment. Should this not be considered.In the material covered in CAPP, the text raises the subject of setup time being in the calculations for piece cost.

Should this not be considered. –Of course, authors consider it part of the operation time/cost, prorate periodic task times

13. © 2000 John W. NazemetzSlide 13 Computer Integrated Manufacturing Systems Discussion Questions I would like the class to discuss the advantages and disadvantages of different organizational structures on concurrent engineering. For example, under one business unit you could be organized such that all the individual elements of the core team are self contained. These would report to one senior management team. The other type of structure is to organize along the lines of functional organizations. For example all design engineering is within one organization, marketing in another, production in another and so on. Each type of structure has its pro and cons as it relates to concurrent engineering. I’d like to hear some discussion within the class about those pros and cons.I would like the class to discuss the advantages and disadvantages of different organizational structures on concurrent engineering.

14. © 2000 John W. NazemetzSlide 14 Computer Integrated Manufacturing Systems Discussion Questions I would also like some discussion relative to the attached material. It does represent the way we do things here at Power Systems. It makes sense to me, but I’m biased by being in the system. What alternatives would the class propose and why?
