a) ​Draw the AOA (Activity-On-Arc) diagram as shown in Chapter 13's Excel Worksheets.

b) ​Formulate the problem of finding project completion time as a LP problem. [You would only need the first 3 columns of the table and the diagram from a) to do the job!]

c) ​Reformulate the problem when crashing the project completion time of 3 weeks is required. That is, reformulate the problem when the project completion time is required to be shorted by 3 weeks. Obviously, crashing is based on shortening the project completion time by 3 weeks with the minimal additional cost. In order to formulate the problem, you need to fill in the blank columns of the table.]

Explain the role of customer service as a component of selling relationships.

CASE STUDY SITUATION

You are the vice president of development for BULLET, the second largest discount retailer in the nation. The senior VP has asked you to analyze a new sales venture and determine how to build a clientele foe the new venture and for traditional BULLET stores.

There are close to 2000 BULLET stores across the country, most anchoring strip malls or outdoor shopping centers. BULLET stores feature typical grocery store items along with pharmacies, apparel, home décor, books, toys, electronics, seasonal items and health and beauty sections. BULLET’S biggest competitor is BOX MART, the leading discount retailer. BULLET does not come close to the number of store locations nor the revenue that BOX MART produces each year. Aside from similar store layouts and product offerings, there are notable differences between the two discount retailers.

Although product offerings are similar, BULLET has a much different image than BOX MART. BULLET is perceived to be better organized, with a more streamlined store layout. They are also more in touch with fashion trends and home décor. BULLET also markets higher quality house brands in all departments, most notably in its food and beverage departments. BULLET offers a wide variety of fresh, ready-to-eat meals that beat BOX MART’S offerings in customer ratings each year.

Executives at BULLET have decided to test market a concept for a BULLET branded convenience store. The BULLET convenience store will be located away form BULLET stores and will offer fuel and the loyal BULLET customer, and also new clientele who does not usually shop at BULLET stores. They are also hoping to attract the BOX MART customer.

YOUR CHALLENGE

The senior VP wants you to determine how a BULLET C-store can feel like a BULLET store, rather than a typical convenience store. You are to suggest techniques tha can expose BULLET C-store customers to BULLET retail store products, ideally resulting in a larger clientele for BULLET retail stores.

In addition, you need to plan the product mix the BULLET C-stores; what typical convenience store products should be sold and what other products should be sold to keep up with BULLET’S well-regarded image? Are there store services that should be offered or not?

Mazlina ventures into agriculture business. She firmly believe that there is market opportunity and demand for organic vegetables provided quality is assured. Even though her business is small, but over the past two years, her company has been exporting fresh organic vegetables to Singapore.

However, there have two main issues that troubled her.

First, there has been a perception that local small medium scale should not waste time to have their company to be ISO certified. ISO has a range of standards for quality management systems that are based on ISO 9001 and adapted to specific sectors and industries. Likewise, there is no reason that agriculture company cannot be ISO qualified. Mazlina is still undecided whether to certify her company with ISO9001:2015 or stay with current status quo. Obviously, she may understand the benefits of an ISO certified company.

Second, there has been issues related to cost. She has strong quality commitment. She maintained a stringent standard operating procedure that each of the organic shipment is thoroughly inspected. In fact, unknowingly she could have overengineered the inspection process. As a result, the cost of producing the vegetables has increased over last 5 months, eroding her margin. In addition, there has been increased of employee turnover. Additional cost was incurred to rehire and retrain all these employees where she wanted them to specialize in the inspection process. There has been a cost of quality with all the additional effort.

Question 1 - Evaluate Mazlina’s options on the quality certification.

Question 2 - What are the categories of cost of quality? Did Mazlina approach in managing quality appropriate and optimal? Provide recommendations.

In his attempt to become “the professor”, he has to present the following discussion points to the committee of referees. Present your answers with an organized, detailed and clear way.

  1. Discuss in what situations one should use Largest Candidate Rule, knowing that Kilbridge and Wester Method and Ranked Positional Weights usually bring solutions that are more accurate.
  2. What should be done in the case of a single work element’s value is greater than  value?
  3. In mixed model line balancing systems, why are we taking AT (available time) as the maximum station time?

The College of Business and Public Administration at Benton University has a copy machine on each floor for faculty use. Heavy use of the five copy machines causes frequent failures. Maintenance records show that a machine fails every 2.5 days (or l = 0.40 failure/day). The college has a maintenance contract with the authorized dealer of the copy machines. Because the copy machines fail so frequently, the dealer has assigned one person to the college to repair them. The person can repair an average of 2.5 machines per day. Using the finite-source model, answer the following questions:

a. What is the average utilization of the maintenance person?

b. On average, how many copy machines are being repaired or waiting to be repaired?

c. What is the average time spent by a copy machine in the repair system (waiting and being repaired)?
