The Laurenster Corporation needs to set up an as-sembly line to produce a new product. The fol-lowing table describes the relationships among the activities that need to be completed for this productto be manufactured. (a) Develop a project network for this problem.(b) Determine the expected duration and variancefor each activity.

You may need to use the appropriate technology to answer this question. Mueller & Associates is a urban planning firm that is designing a new public park in an Omaha suburb. Coordination of the architect and subcontractors will require a major effort to meet the 42- week completion date requested by the owner. The Mueller project manager prepared the following project network. Start Activity A B с D E Estimates of the optimistic, most probable, and pessimistic times (in weeks) for the activities are as follows. TI G H Optimistic Most Probable 4 6 6 weeks 3 6 5 10 A 5 8 7 12 5 9 8 B 15 6 Pessimistic 12 8 18 7 18 17 20 (b) What is the expected project completion time (in weeks)? 52 13 F E (a) Find the critical path.
