Operations Management
- Hudson Corporation is considering three options for managing its data processing operation: continuing with its own staff, hiring an outside vendor to do the managing, or using a combination of its staff and an outside vendor. The profit of the corporation depends on future demand. The annual profit of each option (in thousands of dollars) depends on demand as follows: Demand Staffing Options High Median Low Own staff 650 650 600 Outside vendor 900 600 300 Combination 800 650 500 Recommend a decision based on the use of the optimistic, conservative, and minimax regret approaches. If the demand probabilities are 0.2, 0.5, and 0.3, respectively for High, Median, and Low demands, use the expected value approach to determine the optimal decision(show steps).arrow_forwardCalculating outcomes as equally likely would BEST describe: O a.

- A circus is scheduled to appear in a city on a given date. The profits obtained are heavily dependent on the weather which can be classified as "good" or" bad". The circus owners may choose to setup operations in a large open field that is centrally located or rent a small building to stage a small version of the circus. The small building is not expected to be adversely affected by bad weather – thus will not affect the circus for it is well secure and has covered parking for the guests. The following shows the profits of the options and states of nature: States of nature Decision alternatives Set up in field Rent small building | Probability Good Bad $14,500 $5,000 -$15,000 $4,000 P(G)=0.5 P(B)=0.5 The circus owners may choose to delay the decision until the day before the event is due. At this time they can obtain the one-day weather report (free) which is usually reliable. This delay will however increase their set up cost by $1000.00 or if they choose to rent, the rental cost will…arrow_forwardIn the past, Peter Kelle's tire dealership in Baton Rouge sold an average of 1,000 radials each year. In the past 2 years, 240 and 240, respectively were sold in fall, 350 and 320 in winter,150 and165 in spring, and 340 and 195 in summer. With a major expansion planned, Kelle projects sales next year to increase to 1,200 radials. Based on next year's projected sales, the demand for each season is going to be (enter your responses as whole numbers): Fall: Winter: Spring: Summer:arrow_forwardThe below data is about Weighted population distances between 6 village hamlets, where the local government body plans to open primary health care facilities.

- ChocoTown has a 4,000 square foot outlet store that serves five major customer regions, denoted A, B, C, D and E. The locations of the points representing the customer regions and their weekly demands are shown in the table below. The ChocoTown outlet store is at location (10,20). Customer Region Location Demand ($/week) A (0,10) 4,000 B (0,20) 2,000 C (20,0) 4,000 D (30,20) 3,000 E (40,10) 2,000 CandyTime is a new competitor of ChocoTown and they are considering opening a 4,000 square foot store at location (30,10). Assume the travel time from location i to j in minutes equals the straight line distance from i to j. a) Use the spatial interaction model to estimate the demand that would be captured by the new CandyTime store. Demand captured by CandyTime = ___________ b) Suppose the CandyTime store is located at (30,10), but it is not 4,000 square feet. Use the spatial interaction model to find the size in square feet for…arrow_forwardBenny is the manager of an office-support business that supplies copying, binding, and other services for local companies. He must replace a worn-out copy machine that is used for black- and-white copying. He is considering two machines, and each of these has a monthly lease cost plus a cost for each page that is copied. Machine 1 has a monthly lease cost of $639, and there is a cost of $0.030 per page copied. Machine 2 has a monthly lease cost of $747, and there is a cost of $0.045 per page copied. Customers are charged $.08 per page copied. a. What is the break-even point for each machine? b. If Benny expects to make 75,000 copies per month, what would be the monthly cost for each machine?

- II. + James Scott is considering the possibility of opening a small outfit shop on Sta. Maria District, a few blocks from St. Green Ville College. She has located on a mall that attracts students. To open a small shop, medium sized shop, or no shop at all are her options. The market can be good, average, or bad. The probabilities for these three possibilities are 30% for good market, 50% for an average market, and 20% for bad market. The profit or loss for the said market conditions are given in the table below; ALTERNATIVE Small Shop Medium Sized Shop No Shop GOOD 150,000 200,000 0 AVERAGE 50,000 70,000 0 a) Calculate the Expected Value of Perfect Information (EVPI) b) What do you recommend?
