Consider a three-units system presented bythe cost function as:C1 = 0.03 P12 + 8.2P1 + 452C2 = 0.025 P22 + 8.3P2+ 500C3 = 0.0035 P32 + 7.44P3 + 612Where P1, P2 and P3 are in MW and thetotal load demand, PD is 952 (in MW).(a) Compare these three-units system withand without the economic dispatch bydrawing the bar graphs for the power ofeach plants and the total cost in RM/h.(b) Determine the percentage of saving,with and without the optimal economicdispatch. Discuss the answer.(c) Now, P1, P2 and P3 are subjected to thefollowing limits:50 MW < P1 < 300 MW100 MW < P2 < 400 MW100 MW < P3 < 350 MWCompare with the costs in (a). Justify theanswer.

Given cost function, C1 = 0.03 P12 + 8.2P1 + 452C2 = 0.025 P22 + 8.3P2+ 500C3 = 0.0035 P32 + 7.44P3…

Use the following information for the next 3 problems: ABC Company plans to construct a 60,000 sq. ft private warehouse and rent public warehouse as needed. Warehouse inventory turns at the rate of 2 times per month. One pound of merchandise occupies 0.2 cubic feet of warehouse space and can be stacked 10 feet high. Given aisles, and normal operating efficiency, only 50 percent of the total warehouse space is actually used for storage. Assume the facility is being built to size so no additional space is allowed for future product growth. A private warehouse can be constructed for $36 per sq. ft. and can be amortized over 20 years. Annual fixed costs amount to $20 per sq. ft. of total space. The cost of operation is $0.03 per pound of throughput. Space may also be rented for a storage charge on inventory of $0.06 per pound per month and a handling charge of $0.05 per pound of throughput. Monthly demands for a typical year are as follows: Month Demand (lb) Jan 2,000,000…
A new shoe production line is being designed at a cost of $293,000 and operating costs are expected to be $61,000 per year. Planned annual production is 2800 pairs and the price of a pair of shoes is $77. The line's service life is 12 years, the depreciation rate is 20%. Use a 8% annual interest rate for the base case. Using the interval [-20%, -10%, +10%, +20%], perform a present worth sensitivity analysis using a sensitivity graph with respect to the following variables in terms of their impact on the Present worth. a) First Cost b) Operative cost c) Annual Production d) Salvage Value

Evaluate an alternative that involves consolidating all 20-foot container volumes and using only a single consolidation center in Shanghai/Ningbo. Assume that all the existing 20-foot container volumes and the existing consolidation center volumes are sent to this single consolidation center by suppliers. This new consolidation center volume would be packed into 40-foot containers, filled to 96 percent, and shipped to the United States. The existing 40-foot volume would still be shipped direc t from the suppliers at 85 percent capacity utilization.
A toy manufacturer uses 51,920 rubber wheels per year for its popular dump truck series. The firm makes its own wheels, which it can produce at a rate of 800 per day. The toy trucks are assembled uniformly over the entire year. Carrying cost is $1.30 per wheel per year. Setup cost for a production run is $44. The firm operates 236 days per year. Determine the following: a. Optimal run size (Round your answer to a whole number, following normal rules of rounding.) b. Use your final answer from part a to determine minimum total annual cost for carrying and setup. (Round your answer to a whole number.) c. Cycle time for the optimal run size (Round your answer to two decimal points.) d. Run time (Round your answer to two decimal points.)
Knott's Berry Farm is contemplating buying a new van for its operations. The farm's engineering staff has researched the market and found 2 units that appear to meet their requirements. Truck # 1 has a cost of $37,000 and requires an annual maintenance cost of $2,700. At the end of its useful life (3 years), it is projected to have a salvage value of $5,000. On the other hand, Truck #2 has an initial cost of $40,000 and requires only $2,000 in annual operating costs because the manufacturer is claiming that some routine maintenance is covered in the price of the truck. Truck # 2 has an estimated salvage value of $8,000 at the end of its 4 year service life. The CEO has determined that the farm's MARR is 12%. The trucks are needed for 12 years according to the 2024 Strategic Plan. The Engineering Department has determined that no significant changes are needed in the future that would change prices and functional characteristics of each truck. As a member of the Engineering Department,…

Another approach that might be used relates to the time before a breakdown occurs. Suppose that the average time before breakdown is normally distributed and has a mean of3 weeks and a standard deviation of .60 week. If breakdown cost averages $1,000 and preventive maintenance costs $250, what is the optimal maintenance interval?
Assume that a production line operates such that the production lot size model is applicable. Assume that D = 4,900 units per year, Co = $100, and C₁ = $2 per unit per year. (a) Compute the minimum cost production lot size for each of the following production rates. (Round your answers to the nearest integer.) (i) 8,000 units per year Q* (ii) 10,000 units per year Q* (iii) 32,000 units per year Q* = (iv) 100,000 units per year Q* = (b) Compute the EOQ recommended lot size using equation Q* = Q* = 2DC Ch Comparing the EOQ lot size to the various production lot sizes in part (a), what observations can you make about the relationship between the EOQ model and the production lot size model? (Select all that apply.) As production rate P increases, production lot size Q* increases. O EOQ Q* is greater than production lot size Q*. O Production lot size Q* and EOQ Q* are equal. O Increasing production rate P does not affect production lot size Q*. Production lot size Q* is greater than EOQ Q*.…
