- A company specializing in custom-engineered equipment is planning to submit a proposal to the National 5. Aeronautics and Space Administration (NASA) to build an assembled component for a new space station that NASA plans to launch into orbit. The winning proposal will be selected on the basis of both cost and timely delivery. Also, there will be a penalty clause in the NASA contract for late delivery. The company has developed the schedule of activities that are required to produce the assembled component. The activities and precedence requirements are presented in the table below. Three time estimates (in weeks) are given for each activity: optimistic time, most likely time, and pessimistic time. (a) What completion time should the company specify in its proposal in order to be 85% sure that it will complete the project on time? ij Activity Immediate predecessor Optimistic time (weeks) a b d. h b e, d d e,f f,g h, i a a a 15 8 10 20 17 4 10 Most likely time (weeks) 24 16 10 14 26 23…Innis Investments manages funds for a number of companies and wealthy clients. The investment strategy is tailored to each client’s needs. For a new client, Innis has been authorized to invest up to $1.2 million in two investment funds: a stock fund and a money market fund. Each unit of the stock fund costs $50 and provides an annual rate of return of 10%; each unit of the money market fund costs $100 and provides an annual rate of return of 4%. The client wants to minimize risk subject to the requirement that the annual income from the investment be at least $60,000. According to Innis’ risk measurement system, each unit invested in the stock fund has a risk index of 8, and each unit invested in the money market fund has a risk index of 3; the higher risk index associated with the stock fund simply indicates that it is the riskier investment. Innis’s client also specified that at least $300,000 be invested in the money market fund.

Many organizations today hire highly skilled technical employees on a short-term, temporary basis to assist with special projects or to provide a needed technical skill. PSSM negotiates contracts with its client companies in which it agrees to provide temporary staff in specific job categories for a specified cost. For example, PSSM has a contract with an oil and gas exploration company in which it agrees to supply geologists with at least a master’s degree for $5,000 per week. PSSM has contracts with a wide range of companies and can place almost any type of professional or scientific staff members, from computer programmers to geologists to astrophysicists. When a PSSM client company determines that it will need a temporary professional or scientific employee, it issues a staffing request against the contract it had previously negotiated with PSSM.
