OSHA Assignment 2 The M&M Textile Mill was inspected by OSHA and found to be in violation of a number of safety regulations. The OSHA inspectors orders the mill to alter some existing machinery to make it safer(safer guards etc.); purchase some new machinery to replace older, dangerous machinery; and relocate some machinery to make safer passages and unobstructed entrances and exits. OSHA gives the mill 40 weeks to make the changes; if the changes were not made by then, the mill would be fined $300,000. After consulting with members of the engineering staff, the director compiled a list of activities associated with the project. The mill determined the activities in a CPM/PERT network that would have to be completed and then estimated the indicated activity times, as shown in the following table. Activity Description Immediate predecessor Time estimates a b m Crashed Cost ($) Normal cost ($) Crashed Activity time A Order new machinery - 4 6 8 1900 1000 4 B Plan new physical layout - 6 8 16 1800 1000 7 C Select contractors A,B 2 4 6 2700 1500 2 D Receive equipment C 8 10 24 3200 2000 8 E Receive designs C 7 10 13 8000 5000 7 F Make plant alterations E 4 6 8 4100 3000 4 G Make changes in existing machinery C 4 6 20 10250 8000 5 H Install new machinery D,F,G 4 6 8 6400 5000 4 I Relocate new machinery D,F 4 6 14 12400 10000 4 J Train system operators H 3 4 5 4400 4000 3 K Conduct safety operations I,J 2 4 6 5500 5000 3 Managerial report Develop a report that presents the activity schedule and expected project completion time for the M&M Textile Mill’s safety regulation project. Include project network diagram. Also provide details on the following issues 1. According to OSHA order, can this completion time be achieve? Include probability information in your discussion. What recommendations do you have if the 40-week completion is required? 2. Suppose that management request that activity times be shortened to provide and 80% chance of meeting the 40-week completion time. Then, how much should the expected project completion time be shortened to achieve the goal of an 80% chance of completion within 40 weeks? 3. Using the expected activity times as the normal times and the following crashing information, determine activity crashing decisions and revised activity schedule for the project.
