The table below contains information about an environmental clean-up project in the township of Hiles. Shorten the project three weeks by finding the minimum-cost schedule. Assume that project indirect costs and penalty costs are negligible. Identify activities to crash while minimizing the additional crash costs.

Project Risk Analysis Sydney, Australia’s M5 East Tunnel was constructed under strict budgetary and schedule requirements, but given the massive traffic delays now hampering commuters, the requirements may have been excessive. Due to an inexpensive computer system with a high failure rate, the tunnel’s security cameras frequently fail, requiring the operators to close the tunnel due to inability to react to an accident, fire, or excessive pollution inside the tunnel. The tunnel was built to handle 70,000 vehicles a day, but it now carries 100,000, so any glitch can cause immediate traffic snarls.  A managerial risk analysis, including the risk of overuse, might have anticipated these problems and mandated a more reliable set of computers once the costs of failure had been included. Required: As the project manager, discuss the risk management process you think might have identified the danger in using a cheap computer system Discuss the type of risk analysis approach you think would…
