Always Rain Irrigation, Inc., would like to determine capacity requirements for the next four years to make three types of bronze sprinklers: 90-degree nozzle sprinklers, 180-degree nozzle sprinklers, and 360-degree nozzle sprinklers. Management has forecast demand for the next 4 years as follows: Yearly Demand in 000's: Year 1, Year 2, Year 3, Year 4: Bronze 90: 7, 8, 9, 10 Bronze 190: 3, 4, 5, 6 Bronze 360: 11, 12, 15, 18 The machines needed for the bronze sprinklers require two operators, and can produce up to 12,000 sprinklers. Three bronze machines and only one injection molding machine are available. What are the capacity requirements for the next four years, assume that there is no learning? Capacity: Year 1, Year 2, Year 3, Year 4: Demand for bronze sprinklers: Percentage of capacity used: Machine requirements: Labor requirements:
Small City currently has 1,020,000 square feet of office space, of which 765,000 square feet is occupied by 3,000 employees who are mainly involved in professional services such as finance, insurance, and real estate. Small City’s economy has been fairly strong in recent years, but employment growth is expected to be somewhat lower during the next few years, with projections of an increase of just 130 additional employees per year for the next three years. The amount of space per employee is expected to remain the same. However, a new 153,000 square foot office building was started before the recession and its space is expected to become available at the end of the current year (one year from now). No more space is expected to become available after that for quite some time. Required: a. What is the current occupancy rate for office space in Small City? b. How much office space will be absorbed each year for the next three years? c. What will the occupancy rate be at the end of each…
The Gulf Coast Foundry is developing a long-range strategic plan for buying scrap metal for its foundry operations. The foundry can buy scrap metal in unlimited quantities from two sources, Atlanta (A) and Birmingham (B), and it receives the scrap daily in railroad cars. The scrap is melted down, and lead and copper are extracted for use in the foundry processes. Each railroad car of scrap from source A yields 1 ton of copper and 1 ton of lead and costs $10,000. Each railroad car of scrap from source B yields 1 ton of copper and 2 tons of lead and costs $15,000. If the foundry needs at least 21/2 tons of copper and at least 4 tons of lead per day for the foreseeable future, how many railroad cars of scrap should be purchased per day from Source A and Source B to minimize the long-range scrap metal cost?
Carson Trucking is considering whether to expand its regional service center in Mohab, UT. The expansion requires the expenditure of $10,000,000 on new service equipment and would generate annual net cash inflows from reduced costs of operations equal to $2,500,000 per year for each of the next 8 years. In year 8 the firm will also get back a cash flow equal to the salvage value of the equipment, which is valued at $1 million. Thus, in year 8 the investment cash inflow totals $3, 500, 000. Calculate the project's NPV using a discount rate of 9 percent.
A farmers' cooperative association plans to build a new sugar mill in Georgetown. Theprimary objective of the mill is to provide the farmers with a place to take their crop forprocessing that will reduce their transportation costs. The members of the co-op believe thatthe center-of-gravity method is appropriate for this objective. While there are over 200 sugarcane farms in the region, they are tightly clustered around six villages. Using the data below,use the center-of-gravity method to calculate the coordinates of the best location for this mill.All mileage references use Browns Town as (0,0).VillageMiles East ofBrowns TownMiles North ofBrowns TownSugar CanetonnageBarney Valley 90 10 240,000Blue Pasture 140 60 320,000Congo Valley 20 70 450,000Bower 50 20 120,000Rabacca 100 80 60,000Salem 10 120 140,000

The Scottville "Mill" produces five different fabrics. Each fabric can be woven on one or more of the mill's 38 looms. The sales department has forecast demand for the next month. The demand data are shown in Table 1.0 below along with data on the selling price per yard, variable cost per yard, and purchase price per yard. The mill operates 24 hours a day and is scheduled for 30 days during the coming month. The Mill has two types of looms: dobbie and regular. The dobbie looms are more versatile and can be used for all five fabrics. The regular looms can produce only three of the fabrics. The Mill has a total of 38 looms: 8 are dobbie and 30 are regular. The rate of production for each fabric on each type of loom is given in Table 1.1. The time to change over from producing one fabric to another is negligible and does not have to be considered. The Scottsville Mill satisfies all demand with either its own fabric or fabric purchased from another mill. Fabrics that cannot be woven at…
A semiconductor manufacturer produces a particular solid-state module that it supplies to four different television manufacturers. The module can be produced at each of the corporation's three plants, although the costs vary because of differing production efficiencies at the plants. Specifically, it costs 110 units to produce a module at plant A, 95 units at plant B and 103 units at plant C. Monthly production capacities of the plants are 7500, 10000, and 8100 modules, respectively. Sales forecasts project monthly demand at 4200, 8300,6300 and 2700 modules for television manufacturers I, II, III and IV respectively. If the cost for shipping a module from a factory to a manufacturer is as shown below, find a production schedule that will meet all needs at minimum total cost.

A firm has established a distribution network for the supply of a raw material critical to itsmanufacturing. Currently there are two origins for this material, which must be shipped to threemanufacturing plants. The current network has the following characteristics: COSTS PLANT 1 PLANT 2 PLANT 3 SUPPLY Raw Material source 1 $6 $8 $9 400 Raw Material source 2 $4 $7 $3 600 Demand 500 500 500 Supply < Demand The firm has identified two potential sites for a third raw material source; these are identified asCandidate A and Candidate B. From A, the costs to ship would be $9 to Plant 1, $10 to Plant 2,and $12 to Plant 3. From B, these costs would be $11, $14, and $8. The new source, wherever itis located, will have a capacity of 500 units. Solve with the transportation method. Which siteshould be selected?
