- Assign nine automobile service departments to bays in a 3 × 3 grid so that the closeness ratings Problem 2 in the following matrix are satisfied. (The unimportant and ordinary-importance ratings have been omitted to simplify the example.) The location of department 4 must be in the upper right-hand corner of the grid to satisfy a town ordinance.arrow_forwardA firm that has recently experienced enormous growth is seeking to lease a small plant in Memphis,TN; Biloxi, MS; or Birmingham, AL. Prepare an economic analysis of the three locations given thefollowing information: Annual costs for building, equipment, and administration would be $40,000for Memphis, $60,000 for Biloxi, and $100,000 for Birmingham. Labor and materials are expected tobe $8 per unit in Memphis, $4 per unit in Biloxi, and $5 per unit in Birmingham. The Memphis location would increase system transportation costs by $50,000 per year, the Biloxi location by $60,000per year, and the Birmingham location by $25,000 per year. Expected annual volume is 10,000 units.arrow_forwardFormulate the following as a linear programmingproblem: A greenhouse operator plans to bid for the job ofproviding flowers for city parks.

The company anticipates nationwide demand for the year 2010 to be 180,000 units in the South; 120,000 units in the Midwest; 110,000 units in the East; and 100,000 units in the West. Managers at DryIce are designing the manufacturing network and have selected four potential sites – New York, Atlanta, Chicago, and San Diego. Plants could have a capacity of either 200,000 or 400,000 units. The annual fixed costs at the four locations are shown in the table below, along with the cost of producing and shipping an air conditioner to each of the four markets. Where should DryIce build its factories and how large should they be?

Prepare a cost benefit study for each of the three locations using the following data: The annual construction, facilities, and administration expenses for Memphis, Biloxi, and Birmingham will be $40,000, $60,000, and $100,000, respectively. In Memphis, labour and materials are estimated to cost $8 per month, $4 in Biloxi, and $5 in Birmingham. The Memphis site would add $50,000 a year to device transportation expenses, the Biloxi location would add $60,000 per year, and the Birmingham location would add $25,000 per year.

- The Martin-Beck Company operates a plant in St. Louis with an annual capacity of 30,000 units. Product is shipped to regional distribution centers located in Boston, Atlanta, and Houston. Because of an anticipated increase in demand, Martin-Beck plans to increase capacity by constructing a new plant in one or more of the following cities: Detroit, Toledo, Denver, or Kansas City. The estimated annual fixed cost and the annual capacity for the four proposed plants are as follows: Plant Number Proposed Plant Annual Fixed Cost Annual Capacity 1 Detroit $150,000 10,000 2 Toledo $275,000 20,000 3 Denver $400,000 30,000 4 Kansas City $475,000 40,000 The company's long-range planning group developed forecasts of the anticipated annual demand at the distribution centers as follows.

Sarah is planning on operating a small factory to build the bird feeders. She is looking at two possible locations, A and B. If she chooses location A, the lease on the building will be higher than location B, thus leading to higher fixed costs than what she would have with location B. However, if she makes more than 20,000 units, both locations will likely have to be expanded, both the physical buildings and the manufacturing equipment. Variable costs to produce each unit will vary by location as well as by product. For example, the first design will have variable costs of $10 and $15 in locations A and B respectively, while the second bird feeder design will have variable costs of $20 and $25 respectively depending on location. However, she thinks that variable costs will decrease if she sells more than 5,000 units, as she will receive discounts from her suppliers at that point. She is unsure of…arrow_forwardThere are five machines located at the points (0, 0), (2, 0), (0, 2), (2, 3) and (4,3) respectively. A repair shop is planned in the facility.
