Please do not give solution in image formate thanku. There are four critical paths in a network. A-B-C-D-E, A-F-E, A-B-H-J-K-E and A-S-T-E. Each activity in this network can be crashed by a maximum of 4 weeks. The crashing cost (per week), for the first week (crashing first time), for activity A is: $400, E is $415 and all other activities is : $100 (per week per activity). The crashing cost, second week and onwards(crashing second time), for activity A is $1000 per week, E is $1200 per week and for all other activities is $200 per activity per week. You have a maximum crashing budget of $2505. The maximum possible reduction in the project duration will be: a. 2 weeks b. 3 weeks c. 4 weeks d. 5 weeks e. 6 weeks

An electricity power plant was redesigned so that the old system consisting of a single large display screen which could be seen by all of a team of three operators was replaced by individual workstation screens for operators. This worked well until there was a problem which resulted in dangerous gases being released. The team of operators had great difficulty in finding the source of the problem and deciding what to do. Because they no longer have access to all the information, they have to spend time explicitly co-ordinating their understanding of the situation by talking to each other. Under the old system, the knowledge would be shared – one operator would know what was happening with another’s area of the plant without explicit communication. Although the team’s individual responsibilities would still have been clearly divided, the knowledge of the system would be shared. How could the new system of individual workstations be modified to make better use of distributed cognition?

The Peabody Coal Corporation recently completed the final feasibility report for a new general ledger accounting system. It has hired a consulting firm to program and install the new system. The consulting firm is charging $350,000 for the remaining tasks to be performed. These tasks are to be performed over the next 10 months as detailed in the Gantt chart in the diagram. The consulting firm is extremely concerned with the project staying on schedule because it is receiving a flat fee. The release of the final payment is contingent upon the system performing as stated in the contract and upon Peabody receiving appropriate documentation of the system.Requireda.
