1. Mr. Meadows Cookie Company makes a variety of chocolate chip cookies in the plant in Albion, Michigan. Based on orders received and forecasts of buy-ing habits, it is estimated that the demand for the next four months is 850, 1,260, 510, and 980, expressed in thousands of cookies. During a 46-day period when there were 120 workers, the company produced 1.7 million cookies. Assume that the number of workdays over the four months are respectively 26, 24, 20, and 16. There are currently 100 workers employed, and there is no starting inventory of cookies.

1. What is the minimum constant workforce required to meet demand over the next four months?
2. Assume that cI = 10 cents per cookie per month, cH = $100, and cF = $200. Evaluate the cost of the plan derived in part (a).
3. Formulate as a linear program. Be sure to define all variables and include the required constraints.
4. Solve for the optimal solution.

Suppose that the cost of hiring workers each period is $100 for each worker until 20 workers are hired, $400 for each worker when between 21 and 50 workers are hired, and $700 for each worker hired beyond 50.

5. Write down the complete linear programming formulation of the revised problem.

Suppose that the objective of a two-variable optimization model is to maximize 20X1 + 13X2, and that we find by graphing that the binding constraints are:

(3) 9X1+3X2≤87 (7) 4X1+6X2≤62

Based on the above, the optimal solution is at X1 = 8, X2 = 5, and OFV = 225.

(a) For the objective function coefficients, find the allowable increase and decrease for each coefficient (based on one-at-a-time changes).

(b) Suppose that the right-hand side of (3) is changed to 87+∆b3. Find expressions for the values of X1, X2, and OFV as a function of ∆b3, and from the latter state the shadow price of this constraint. [Do not worry about the allowable range.]

Background: Judith and Eric Sultan own a business providing HR decision-making expertise to employers across the nation. The name of their business is HRM Analysis Services. Their business is located in Phoenix and has grown exponentially since 2005. Up to this point they have not had their own employees, but instead hired established consultants (often called management analysts) to work on a project-by-project basis.

They want to hire three full-time management analysts to work in three different locations: San Francisco, Philadelphia, and Miami. The analysts would scout out work in their designated regions and manage the contracting and oversight of contractual consultants.

Judith and Eric plan to keep ownership of the company, but want to step away from the day-to-day as soon as the business is working well enough without them.

The focus of this assignment is to assist Judith and Eric with the selection of three Management Analysts by coming up with a weighted formula of important selection factors.

Alison is making a large fruit salad for a party. She has everything she needs at home, except for watermelons and grapefruit. She needs 12 watermelons, and 31 grapefruit. She goes to a nearby fruit stand, where she finds two vendors selling bags of mixed fruit. Vendor 1 is selling bags containing four watermelons, and five grapefruit, for $18 per bag. Vendor 2 is selling bags containing two watermelons and ten grapefruits for $13.50 per bag. Vendor 1 bags have a mass of 2 kg; Vendor 2 bags have a mass of 3.2 kg. Alison cannot carry more than 16 kg.

(a) Formulate a cost minimization integer model for this problem.

B) On the graph below, draw the constraints and show the (linear) feasible region. On this region show all the dots representing the feasible integer solutions. Determine the optimal values for the two variables and the OFV, and give the recommendation.

We can all agree that we never want to go through a bankruptcy. However, it is in all of our best interests to truly understand the bankruptcy law and process. For this assignment, I would like you to read the following case and answer the questions presented. This may require that you do some research on bankruptcy. Remember, any sources you use must be cited and I do not want you to copy answers from the internet. Think about the situation and apply your knowledge, gained from your readings, to the questions. One to two paragraphs for each question.

Jane Doe, a teacher, obtained a master’s degree at Somewhere University (names have been changed). But when Doe asked for a transcript—which was required to receive an increase in salary from her school district—the university refused because she owed more than $6,000 in tuition. Doe offered to pay the nominal transcript fee, but not the tuition. She then filed a petition in a federal bankruptcy court, listing the university as her only creditor, and while the case was pending, again asked for a transcript. The university again refused unless she paid the tuition. Doe complained to the court, which ordered the university to provide a transcript. A federal district court affirmed the order. The university appealed.

The U.S. Court of Appeals for the Seventh Circuit affirmed. Doe had a right to a copy of her transcript, and the university’s refusal to honor that right until she paid her tuition was an act to collect a debt, in violation of the automatic stay. Property interests are created and defined by the law. Nothing in the Bankruptcy Code or other federal law creates or affects property rights in grades or the right to a transcript. No state statute applies either, but under the state’s common law, property rights may arise from custom. In the state, universities have consistently provided certified transcripts at or around cost. This indicates that providing a transcript is an implied part of the “educational contract,” covered by the tuition and other fees. Because a transcript is part of the package of goods and services that a college offers in exchange for tuition, a student has a property right to a certified copy. In this case, Doe was willing to pay the cost. The university’s only reason for refusing to provide the transcript was to induce Doe to pay her unpaid tuition. But the automatic stay prohibits a creditor from acting to collect a claim against a debtor that arose before the filing of a bankruptcy petition.

1. What actions might a college take to collect unpaid tuition that would not violate the Bankruptcy Code?

2. Does the longstanding existence of a custom—in this case, the nominal amount of the fee charged by a college for a transcript—mean that it cannot change?

3. To avoid conflicts such as the one in this case, could a college charge a student a high fee for a transcript—for example, one that would equal the amount of any unpaid tuition?
   
4. Suppose that instead of offering to pay for a transcript, Doe had tried to obtain one on credit. Would the university’s refusal to provide one on that basis have led to the same result? Why or why not?
   
5. Some might say that higher education institutions should be able to use all methods possible to collect unpaid tuition, including withholding certified grade transcripts. What ethical issues would this approach raise?

A company which produces a single product has definite orders for this product over the next four quarters as follows:

The company ended the previous year with an inventory of 300 units, and the final quarter production level was 420 units. The company wishes to end this year with an inventory of at least 280 units.

It costs $30 per unit to increase the production level from one quarter to the next, and $56 per unit to decrease it. The cost of holding inventory from one quarter to the next is $40 per unit per quarter. No shortages are permitted. The company wishes to minimize the sum of production level change costs and inventory costs over the four quarter planning horizon.

Formulate (but do not solve) a model for this situation.

Teloxy Engineering has received a one-time contract to design and build 10,000 units of a new product. During the proposal process, management felt that the new product could be designed and manufactured at a low cost. One of the ingredients necessary to build the product was a small component that could be purchased for $60 in the marketplace, including quantity dis- counts. Accordingly, management budgeted $650,000 for the purchasing and handling of 10,000 components plus scrap.

During the design stage, your engineering team informs you that the final design will require a somewhat higher-grade component that sells for $72 with quantity discounts. The new price is substantially higher than you had budgeted for. This will create a cost overrun.

You meet with your manufacturing team to see if they can manufacture the component at a cheaper price than buying it from the outside. Your manufacturing team informs you that they can produce a maximum of 10,000 units, just enough to fulfill your contract. The setup cost will be $100,000 and the raw material cost is $40 per component. Since Teloxy has never manu- factured this product before, manufacturing expects the following defects:

Percent defective 0 10 20 30 40 Probability of 10 20 30 25 15

occurrence
All defective parts must be removed and repaired at a cost of $120 per part.

1. Using expected value, is it economically better to make or buy the component?
   
2. Strategically thinking, why might management opt for other than the most economical
   choice?
