QUESTION 7The Stone River Textile Mill was inspected by OSHA and found to be in violation of a number ofsafety regulations. The OSHA inspectors ordered the mill to alter some existing machinery to make itsafer (add safety guards, etc.); purchase some new machinery to replace older, dangerousmachinery; and relocate some machinery to make safer passages and unobstructed entrances andexits. OSHA gave the mill only 35 weeks to make the changes; if the changes were not made by then,the mill would be fined $300,000.The mill determined the activities in a CPM/PERT network that would have to be completed and thenestimated the indicated activity times, as shown in the following Table 6:Table 6ActivityDescriptionABсDEFGHIJKActivity DescriptionOrder new machineryPlan new physical layoutDetermine safety changes in existing machineryReceive equipmentHire new employeesMake plant alterationsMake changes in existing machineryTrain new employeesInstall new machineryRelocate old machineryConduct employee safety orientationActivityPredecessor(s)AABCD, ED, E, FD, E, E, GH, I, JTime Estimates (weeks)a121431052122m25310715934523852512251476102 Construct the project network for this project and determine the following:a) Expected activity timesb) Earliest and latest activity times and activity slackc) Critical pathd) Expected project duration and variancee) The probability that the mill will be fined $300,000
