There is little difference in the production time required for the various models; the plant is designed to produce 160 frying pans per eight-hour shift, and there are two shifts per working day. However, the plant does not operate for the full eight hours: the employees take two 15minute breaks in each shift, one in the first four hours and one in the second four hours; two hours per week are devoted to cleaning the factory and performing maintenance on the machines; one four-hour period every four weeks is devoted to the meeting of the quality circle. The plant usually produces about 3,500 frying pans per four-week period. You may ignore holidays in solving this problem. Answer the following questions by adjusting the data to a four-week time period. a. What is the design capacity in frying pans? b. What is the effective capacity in frying pans? As a percent? c. What is the actual output? d. What is the efficiency? e. What is the utilization? PROBLEM NO# 2 (15%) Owns Company manufacturer’s tennis racquets. The selling price per racquet average $320 and variable cost per racquet are $190. The sales volume in dollars which produces a net income of $403,000 is 3,104,000. a. What is the total fixed cost? b. What is the total variable cost? c. What is the break even in units? d. Compute the quantity of units above break even that reach the above net income? e. What is the quantity sold if the net income is 15% of total sale? PROBLEM NO# 3 (20%) Kenneth Brown is the principal owner of Brown oil Inc. After quitting his university teaching job, Ken has been able to increase his annual salary by a factor over 100. At the present time, Ken is forced to consider purchasing some more equipment for Brown Oil because of competition. Ken is planning to purchase one of the three equipment: i. Sub 100: If there is a favorable market, he will realize a profit of $ 300,000 on one hand, if the market is unfavorable; ken will suffer a loss of $ 200,000. ii. Oiler J: If there is a favorable market, he will realize a profit of $250,000 on one hand, if the market is unfavorable, Ken will suffer a loss of $ 100,000 iii. Texan: If there is a favorable market, he will realize a profit of $ 75,000 on one hand, if the market is unfavorable; Ken will suffer a loss of $ 18,000. 1) Construct a decision Table 2) Construct Decision Tree 3) Which Equipment you will recommend to Ken to purchase under the following criterion:a) Optimistic b) Pessimistic c) Equally Likely 4) If the probability of Favorable market is 0.35 which equipment will recommend to Ken based in Expected Monetary Value Criteria. EXERCISE NO#4 (15%) Fall has come, and the department manager of the Purple Pentagon Discount Store must decide how many snow blowers to order for the winter season. He believes there is an association between the weather and the demand for snow blowers: a winter with heavy snow should produce a high demand, and a winter with light snow should produce a low demand. However, if he guesses wrong and orders a large number of snow blowers when the weather turns out to have light snow, he will suffer a loss. Here is his payoff matrix. States of Nature Heavy Medium Light snow snow snow Alternatives a. b. c. d. Large Order $5,000 $1,000 $(4,000) Medium Order 2,000 3,000 (2,000) Small Order 500 500 1,000 Which alternative should be selected under the maximax criterion? Which alternative should be selected under the maximin criterion? Which alternative should be selected under the Laplace criterion? if the probability of heavy snow is 30% Medium snow is 50% what is the value of expected monetary value? EXERCISE NO#5 (15%) A fabric firm has received an order for cloth specified to contain at least 45 pounds of cotton and 25 pounds of silk. The cloth can be woven out of any suitable mix of two yarns A and B. They contain the proportions of cotton and silk (by weight) as shown in the following table: A B Cotton Silk 30% 60% 50% 10% Material A costs $3 per pound, and B costs $2 per pound. What quantities (pounds) of A and B yarns should be used to minimize the cost of this order? EXERCISE NO#6 (15%) A toy workshop makes doll houses and rocking horses. The warehouse can store materials for up to 800 doll houses and 600 rocking horses. The workshop only has 3800 hours per week available for assembling toys and 3300 hours per week for painting toys. It takes 3 hours to assemble and 1 hour to paint each rocking horse. It takes 4 hours to assemble and 4 hours to paint each doll house. If the profit for each rocking horse is $15 and the profit for each doll house is $30, how many of each should they make to maximize profits within the workshop limitations?
