Schware Foundry, Inc., a metal works plant in Tucker Valley Park, Macoya, has long been trying to avoid the expense of installing air pollution control equipment. The local environmental protection group has recently given the foundry 16 weeks to install a complex air-filter system on its main smokestack. Schware Foundry was warned that it will be forced to close unless the device is installed in the allotted period. Kimberley Headley wants to make sure the installation of the filtering system progresses smoothly and on time. All activities involved in the foundry project are shown in the Table 1 and Table 1.1. i) What is the probability that the project can be completed within 16 weeks? ii) What information did PERT (three time estimate) provide Schware?

Chatham Automotive purchased new electric forklifts to move steel automobile parts two years ago. They cost $65,000 each, including the charging stand. In practice, it was found that they did not hold a charge as long as claimed by the manufacturer, so operating costs are very high. As a result, their current salvage value is about $9,000. Chatham is considering replacing them with propane models. New propane forklifts cost $58,000 each. After one year, they have a salvage value of $40,000, and thereafter decline in value at a declining-balance depreciation rate of 20 percent, as does the electric model from this time on. The MARR is 8 percent. Operating costs for the electric model will be $19,000 this year, rising by 12 percent per year. Operating costs for the propane model will initially be $11,000 over the first year, rising by 12 percent per year. Should Chatham Automotive replace the forklifts now? Find EAC for both propane and elctric forklifts. P.S. Show…
Telephone poles, once installed in a location, remain in useful service until one of a variety of events occur. (a) Name three reasons why a telephone pole might be removed from useful service at a particular location. (b) You are to estimate the total useful life of telephone poles. If the pole is removed from an original location while it is still serviceable, it will be installed elsewhere. Estimate the optimistic life, most likely life, and pessimistic life for telephone poles. What percentage of all telephone poles would you expect to have a total useful life greater than your estimated optimistic life? (c) What is an environmental life cycle assessment (LCA)? How do treated wood, metal, and concrete poles compare?

Statement of the Problem and Solutions Rollin King and Herb Kelleher started Southwest Airlines in 1971 with this idea: if they could take airline passengers where they want to go, on time, at the lowest possible price, and have a good time while doing it, people would love to fly their airline. The result? No other airline in the industry's history has enjoyed the customer loyalty and extended profitability for which Southwest is now famous. The company now flies more than 3,400 times each day to over 64 destinations across the United States There's more to the story, however, than making promises and hoping to fulfill them. A large part of Southwest Airlines' success lies in its ability to plan long-term capacity to better match demand, as also improving the utilization of its fleet by turning around an aircraft at the gate faster than its competitors. Capacity at Southwest is measured in seat miles, and even a single minute reduction in aircraft turnaround time system wide means…
