Question 3. Scheduling

ArtWork is a graphic design company. All jobs it receives must go through sketching (Process X) and then colouring (Process Y) in sequence. Each of the processes is operated by a dedicated designer.

1. The above 10 jobs have just arrived. Use Johnson’s rule to determine the optimal sequence to schedule the jobs. If there is more than one optimal sequence, show them all.

E

2. Draw a Gantt chart for your schedule. If there is more than one optimal sequence, show anyone of them.

3. Calculate the average flow time.

4. If you are allowed to split the last job in the sequence (pay attention, not necessarily the
   1. last job in the table) into two equal halves. For example, a job spends 6 hours in X and 4 hours in Y can be split into two jobs of 3 hours in X and 2 hours in Y. Without changing the sequence, do you think this arrangement is quicker? Why or why not?
5. The company has received four special jobs. These jobs have to go through sketching (Process X), colouring (Process Y) and then printing and coating (Process Z) in sequence. Each of the processes is operated by a dedicated designer. What is the optimal sequence to schedule the jobs? Show your steps. [hint: self-study is required]

You are to prepare a cost estimate for producing 1000 assemblies. Each assembly consists of a cylindrical tube, two identical end covers, and a purchased bracket. The brackets cost $8.25 each. Each tube costs $180 for the casting and requires 2.5 standard hours of machining. It requires 12 hours to set up the machining operations and a setup is good for the machining of 500 castings. The end covers are produced on a punch press that requires 1.2 hours per cover of run time and 4.0 hours for press setup. Press setup is good for producing 400 pieces. Material costs per cover is $.50. The direct labor rate is $16.00 per hour. Manufacturing overhead is 150 percent of direct manufacturing labor. Material overhead is 3 percent of the total material and subcontract amount. General and administrative costs are 15 percent of labor and material with appropriate overhead.

What is the calculated unit cost through general and administrative costs? Show your calculations

You are to prepare a bid for producing 100 brackets. The brackets are made on a punch press and screen printed with a part number. All screen printing is done at one time, but the brackets are made in batches of 40. Punch press set up time is 2 hours per setup and .05 hour per print. Screen printing required is 6 minutes per bracket. Assume no attrition or learning curve on either process. Material cost is $.50 per piece. Direct labor rate is $15.00 and overhead is 200 percent of direct labor. G&A is 30 percent of total material, labor, and overhead costs. A 10 percent profit is expected.

                What is your total bid price for the 100 brackets? Show your calculations.

The John Day Company proposed a general and administrative (G&A) rate of 16.8 percent of total manufacturing costs on a 20x8 proposal. The contractor provided the following data upon the request of the contract negotiator who desired to analyze the rate.

1. Does the proposed 20x8 G&A rate appear to be reasonable for the estimated total manufacturing group? Include your rationale.
2. If not, based on historical information above, what G&A rate appears reasonable? Explain.

Case Problem 2 Chapter 7 Introduction to Linear Programming Production Strategy

Production Strategy Better Fitness, Inc. (BFI) manufactures exercise equipment at its plant in Freeport, Long Island. It recently designed two universal weight machines for the home exercise market. Both machines use BFI-patented technology that provides the user with an extremely wide range of motion capability for each type of exercise performed. Until now, such capabilities have been available only on expensive weight machines used primarily by physical therapists. At a recent trade show, demonstrations of the machines resulted in significant dealer interest. In fact, the number of orders that BFI received at the trade show far exceeded its manufacturing capabilities for the current production period. As a result, management decided to begin production of the two machines. The two machines, which BFI named the Body- Plus 100 and the BodyPlus 200, require different amounts of resources to produce. The BodyPlus 100 consists of a frame unit, a press station, and a pec-dec station. Each frame produced uses 4 hours of machining and welding time and 2 hours of painting and finishing time. Each press station requires 2 hours of machining and welding time and 1 hour of painting and finishing time, and each pec-dec station uses 2 hours of machining and welding time and 2 hours of painting and finishing time. In addition, 2 hours are spent assembling, testing, and packaging each BodyPlus 100. The raw material costs are $450 for each frame, $300 for each press station, and $250 for each pec-dec station; packaging costs are estimated to be $50 per unit. The BodyPlus 200 consists of a frame unit, a press station, a pec-dec station, and a leg- press station. Each frame produced uses 5 hours of machining and welding time and 4 hours of painting and finishing time. Each press station requires 3 hours machining and welding time and 2 hours of painting and finishing time, each pec-dec station uses 2 hours of machining and welding time and 2 hours of painting and finishing time, and each leg-press station requires 2 hours of machining and welding time and 2 hours of painting and finishing time. In addition, 2 hours are spent assembling, testing, and packaging each BodyPlus 200. The raw material costs are $650 for each frame, $400 for each press station, $250 for each pec-dec station, and $200 for each leg-press station; packaging costs are estimated to be $75 per unit. For the next production period, management estimates that 600 hours of machining and welding time; 450 hours of painting and finishing time; and 140 hours of assembly, testing, and packaging time will be available. Current labor costs are $20 per hour for machining and welding time; $15 per hour for painting and finishing time; and $12 per hour for assembly, testing, and packaging time. The market in which the two machines must compete suggests a retail price of $2400 for the BodyPlus 100 and $3500 for the BodyPlus 200, although some flexibility may be available to BFI because of the unique capabilities of the new machines. Authorized BFI dealers can purchase machines for 70% of the suggested retail price. BFI’s president believes that the unique capabilities of the BodyPlus 200 can help position BFI as one of the leaders in high-end exercise equipment. Consequently, she states that the number of units of the BodyPlus 200 produced must be at least 25% of the total production. Managerial Report Analyze the production problem at Better Fitness, Inc., and prepare a report for BFI’s president presenting your findings and recommendations. Include (but do not limit your discussion to) a consideration of the following items: 1. The recommended number of BodyPlus 100 and BodyPlus 200 machines to produce 2. The effect on profits of the requirement that the number of units of the BodyPlus 200 produced must be at least 25% of the total production 3. Where efforts should be expended in order to increase contribution to profits Include a copy of your linear programming model and graphical solution in an appendix to your report.

A large firm employing tens of thousands of workers has been accused of discriminating against its female managers. The accusation is based on a random sample of 40 managers. The mean annual salary of the 20 female managers is $79,500 while the mean annual salary of the 20 male managers is $103,250. The president of the firm points out that the company has a strict policy of equal pay for equal work and that the difference may be due to other variables. Accordingly, he found and recorded the number of years of education and the number of years of experience for each of the 40 managers in the sample. Also recorded are the salary and gender (1 = female and 0 = male). The data are in attached Excel document. The president wanted to know whether a regression analysis would shed some light on the issue.

A boy standing on top of a building throws a small ball from a height of H₁ = 45.0 m. (See figure.) The ball leaves with a speed of 26.9 m/s, at an angle of 61.0 degrees from the horizontal, and lands on a building with a height of H₂ = 12.0 m. Calculate for how long the ball is in the air. (Neglect air friction, and use g = 9.81 m/s².)

Problem 1. A boy has a fever after coming home in the afternoon. His mother thinks that it could be related to the following three possible reasons: A : He plays football in the rain, B : He takes a cold water shower after playing, C : He eats too many ice creams.

(iii) The mother has 80% confidence that her son’s fever is caused by at least one of the three reasons. She further estimates that the probabilities of the three individual reasons are 0.5, 0.5, 0.2 respectively, and she believes that they are pair- wisely independent. Are the three reasons mutually independent?

(iv) Suppose that the mother is 100% sure that her son’s fever is caused by at least one of the three reasons. Moreover, she believes that they are mutually inde- pendent although she doesn’t know the exact probabilities of any of the individual reasons. After a moment’s thought, she tells her son that one of the three reasons must be certain (that is, one of P(A) = 1 or P(B) = 1 or P(C) = 1 must be true)! Should the boy believe his mother’s assertion?
