Q: We warned you about clearing denominators in the quality constraints. This

We warned you about clearing denominators in the quality constraints. This problem illustrates what can happen if you don’t do so. a. Implement the quality constraints as indicated in Inequality (4.3)...

Q: Run a one-way sensitivity analysis on the optimal solution to

Run a one-way sensitivity analysis on the optimal solution to the unit selling price of drug A in the Repco model. If this price is high enough, will Repco start selling drug A in addition to producin...

Q: Suppose there is a fourth drug, drug D, that Repco

Suppose there is a fourth drug, drug D, that Repco can produce and sell. Each unit of drug D requires four labor hours, one unit of drug A, and one unit of drug C to produce, and it sells for $150 per...

Q: We claimed that the Repco model could either constrain the units produced

We claimed that the Repco model could either constrain the units produced to be greater than or equal to the units used by production or constrain the units sold to be nonnegative. Modify the model to...

Q: In a production process model such as Repco’s, certain inputs make

In a production process model such as Repco’s, certain inputs make no sense in the usage table (the range B7:D9 of the model). For example, suppose that, in addition to current usages, each unit of dr...

Q: Suppose, in addition to the shows already listed, General Flakes

Suppose, in addition to the shows already listed, General Flakes wants to open the possibility of purchasing ads on the “Good Morning America” show on ABC. Make up any reasonable input data you need t...

Q: In the Barney-Jones investment model, increase the maximum amount

In the Barney-Jones investment model, increase the maximum amount allowed in any investment to $150,000. Then run a one-way sensitivity analysis to the money market rate on cash. Capture one output va...

Q: Create a one-way data table in the Acron model to

Create a one-way data table in the Acron model to see how the NPV varies with discount rate, which is allowed to vary from 8% to 18% in increments of 0.5%. Explain intuitively why the results go in th...

Q: Modify the Barney-Jones investment model so that a minimum amount

Modify the Barney-Jones investment model so that a minimum amount must be put into any investment, although this minimum can vary by investment. For example, the minimum amount for investment A might...

Q: We claimed that our model for Barney-Jones is generalizable.

We claimed that our model for Barney-Jones is generalizable. Try generalizing it to the case where there are two more potential investments, F and G. Investment F requires a cash outlay in year 2 and...
