- For the past five years we at the Miami International Airport have been overwhelmed with the number of flight traffic that is coming in and out of our airport daily. Our reports indicate that due to the traffic numerous airlines have complained that their flights are often being delayed. Hence, to meet the needs of our customers we have decided to construct an additional runway area on the open area located north of Terminal A. This new runway must be built to accommodate largest jets. The work that needs to be done includes: Constructing the runway (presently the runway surface is made of concrete), Placing the lights on the runway, building and identify the Runway Safety area, and the construction of blast padsOM Builders Inc. is starting a brand-new development of 10 residential houses in an up and coming neighborhood. The previous housing development completed by OM Builders Inc. was its first development and experienced significant issues with town permits, scheduling, delayed shipments, incorrect furniture and equipment and meeting the closing date of homes. The owner of the firm has met with his management team to discuss how the company can ensure a more efficient, less error-prone project for this new development. The management team decided to use project management tools suggested by a recent graduate the firm hired from a Global Business Management college program. The objectives for the new development are to reduce the number of errors, ensure that schedules are prepared properly and followed and the completion of the project by the promised closing date. The company is currently negotiating with the current owners of the land to be developed and a deal is imminent. During the…Quorex is evaluating two mutually exclusive projects. Project A has a net investment of $50,000 and net cash flows over a six-year period of $13,000 per year (NOTE: that project requires a reinvestment with the same cost and cash flow for another six years). Project B has a net investment of $48,500, but its net cash flows of $8,740 per year will occur over a 12-year period. If Quorex has a cost of capital of 14% for these projects, which project, if either, should be chosen, and what is its NPV?
- 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 table below contains data for the installation of new equipment in a manufacturing process at Excello Corporation.

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
- Baha is a professional Chemical Engineer. He has been appointed as the department manager for an upcoming large chemical process plant that will be designed and constructed by the organization that he is currently attached to. Baha's responsibilities will include organizing the process unit staff and overseeing the project designers' sketch plans to ensure that the new plant will be designed safely, operable and maintainable. After the construction, he will then be responsible to start up the plant. From experience, Baha noted that a new type of valve sold by a newer supplier could be used in place of more common gate valves sold by established suppliers. In any case, the new valve was less expensive and often gave a tighter shut-off than the current gate valve used by his organization. Thus, Baha convinced the project designers to add more of these new valves to the design of the process unit. His decision improved safety because more flows could be shut off instantaneously in an…As the Operations Manager of Shane Manufacturing Ltd., you are given the task to balance the assembly line that is used to produce a special type of toy. a.
