- A company is willing to develop their rocket before the end of current financial year which is now 28 weeks away. The chief engineer of the company has decided to use PERT technique in order to plan, schedule and control program of development for the data given in table below. What is the probability that the program will be completed by the end of the current financial year? (all durations are in weeks). (i) G) Optimum Duration Most likely duration Pesimistic duration 1 2 3 8 13 3 2 8 4 3 8 10 4 7 10 3 6. 3 8 4 9 10 4 8. 4 9. 5 7 9. 12 6. 5 11 7 9. 14 8 4. 00 2.Stinnett Transmissions, Incorporated, has the following estimates for its new gear assembly project: Price $1,220 per unit; variable costs = $3.75 million; quantity = 90,000 units. Suppose the company believes all of its estimates are accurate only to within ±15 percent. What values should the company use for the four variables given here when it performs its best-case scenario analysis? What about the worst-case scenario? Pls don't copy answer i give up voteHow Can You Get to a Backlog of over 100 Projects? There are never enough resources to get everything done." Backlogs build over time. Sacred cow projects get included in the selection system. Projects proposed from people who have left the airline stil reside in the project portfolio. Non-value-added projects somehow make their way into the project portfolio. Soon the queue gets longer. With everyone in IT working on too many projects concurrently, project completion and productivity are slow. Which Projects Remain? To cut the number of projects, the steering committee used a weighting scheme that reflected the airline's priorities, which were: fly safe, generate revenue, reduce costs, and customer service. The weighting scheme easily weeded out the fluff. Coady noted that "by the time you get to the 20s the margin of differentiation gets narrower and narrower." Of the remaining projects, project sponsors had to have solid justification why their project is important. Reduction of the…

The different mechanisms have three different setup costs (overheads) and variable costs and, therefore, the profit from the dolls is dependent on the volume of sales. The anticipated payoffs are as follows: Light Demand Moderate Demand Heavy Demand Probability 0.25 0.45 0.3 Wind-up action $325,000 $190,000 $170,000 Pneumatic action $300,000 $420,000 $400,000 Electrical action -$400,000 $240,000 $800,000 What is the ultimate objective in the use of decision trees to product design? How is this objective accomplished? Draw the decision tree. What is the EMV of each decision alternative? Which action should be selected?
- 1. Decision Rules. A company is choosing a motorized mechanism for a new toy, a dancing ballerina (TippiToes) that is currently under development. Demand is uncertain. but the company is confident that demand will be: Light (25,000 units), Moderate (100,000 units) or Heavy (150,000) units. The payoff table for each mechanism (in $) is given below. Action: Choice of Mechanism Event Gears and Levers Spring Weights and Pulleys Pneumatic Light 25,000 -10,000 -125,000 -300,000 Moderate 400,000 440,000 400,000 300,000 Heavy 650,000 740,000 750,000 700,000 Questions: (1) Apply Maximax, Maximin, Minimax Regret, and EMV rules (assuming that the probability of Light demand is 0.1, Moderate demand is 0.7, and Heavy demand is 0.2) to decide what mechanism should the company choose? (2) What is the expected value of perfect information? (3) Draw a decision tree to solve this problem.The following scenario list comprises two different teachers and the marking system each employs. List the advantages and disadvantages of each. Also, identify the approximate weights that you believe should be placed on each part of each system. Mr. Williams is a sixth-grade teacher who is known as a strict grader. 100% of a student’s grades is based upon his or her weekly classroom tests, with only one exception: the student who improves the most in each subject during the grading period automatically receives an “A” for that subject. Ms. Wallace believes that every grade should reflect precisely what a student does or does not know. Therefore, her testing strategy is to administer criterion-referenced tests exclusively, in which the grade given reflects the number and type of concepts mastered. She then uses these grades to provide either remedial or advanced work to those who need it.c. What is the probability of completion in 20, 21, and 22 weeks? Use Appendix A to answer the question. Do not round intermediate calculations. Round your answers to four decimal places. Probability of completion in 20 weeks: Probability of completion in 21 weeks: Probability of completion in 22 weeks:
