At the beginning of each week, a machine is in one of four conditions: 1 = excellent; 2 = good; 3 = average; 4 = bad. The weekly revenue earned by a machine in state 1, 2, 3, or 4 is 100, 90, 50, or 10, respectively. After observing the condition of the machine at the beginning of the week, the company has the option, for a cost of 200, of instantaneously replacing the machine with an excellent machine. The quality of the machine deteriorates over time, as shown in the file P10 41.xlsx. Four maintenance policies are under consideration: Policy 1: Never replace a machine. Policy 2: Immediately replace a bad machine. Policy 3: Immediately replace a bad or average machine. Policy 4: Immediately replace a bad, average, or good machine. Simulate each of these policies for 50 weeks (using at least 250 iterations each) to determine the policy that maximizes expected weekly profit. Assume that the machine at the beginning of week 1 is excellent.

Management of Mittel Rhein AG of Köln, Germany, would like to reduce the amount of time between when a customer places an order and when the order is shipped. For the first quarter of operations during the current year the following data were reported: Inspection time- 0.7 daysWait time (from order to start of production) -16.6 daysProcess time -2.7 daysMove time -1.3 daysQueue time- 4.5 daysRequired:1. Compute the throughput time. (Round your answer to 1 decimal place.) 2. Compute the manufacturing cycle efficiency (MCE) for the quarter. (Round your answer to the nearest whole percentage (i.e., 0.12 should be entered as 12).) 3. What percentage of the throughput time was spent in non–value-added activities? (Round your answer to the nearest whole percentage (i.e., 0.12 should be entered as 12).) 4. Compute the delivery cycle time. (Round your intermediate calculations and final answer to 1 decimal place.) 5. If by using Lean Production all queue…
Employees at Precision Engine Parts Company produce parts according to exact design specifications. The employees are paid according to a piece-rate system, wherein the faster they work and the more parts they produce, the greater their chances for monthly bonuses. Management suspects that this method of pay may contribute to an increased number of defective parts. A specific part requires a normal, standard time of 23 minutes to produce. The quality control manager has checked the actual average times to produce this part for 10 different employees during 20 days selected at random during the past month and determined the corresponding percentage of defective parts, as follows: Develop a linear regression model relating average production time to percentage defects to determine whether a relationship exists and the percentage of defective items that would be expected with a normal production time of 23 minutes.
Patrick is a quality control inspector at a pharmaceutical plant. He and his team are bound by strict quality standards to ensure that each unit is produced in a way that guarantees safety and effectiveness for the consumer. Recently, Patrick has been criticized for rejecting too many samples of the pharmaceuticals being produced. His manager has warned him that his inspection failure rate is negatively affecting the plant's productivity and that he should "reexamine" his inspection methods. Patrick does not want to be responsible for allowing an ineffective or dangerous medication to be sold to a patient, but he also does not want to lose his job. How can technology help Patrick ensure the quality of the products he is inspecting while at the same time protecting his job?
Vilfredo Pareto was a famous engineer/economist in the 19th and early 20th centuries. He reportedly expressed this 80/20 Rule: 80% of all progress results from 20% of the actions taken. The Pareto Diagram, also called a Juran Diagram, depicts a variant 80/20 Rule: 80% of all production problems come from 20% of the problem areas. a. What kind of statistical chart is the Pareto Diagram? ____ (enter H for histogram, P for probability distribution, T for a Taguchi chart, A for all three of these. N for none of these. b. The value of the Pareto Diagram is its highlighting the areas causing 80% of quality problems. ____ (enter T for true or F for false)
Aspen Plastics produces plastic bottles to customer order. The quality inspector randomly selects four bottles from the bottle machine and measures the outside diameter of the bottleneck, a critical quality dimension that determines whether the bottle cap will fit properly. The dimensions (inch) from the last six samples are: BOTTLE Sample 1 2 3 4 1 0.694 0.622 0.698 0.69 2 0.687 0.611 0.697 0.613 3 0.671 0.680 0.695 0.602 4 0.610 0.615 0.685 0.678 5 0.680 0.624 0.618 0.614 6 0.685 0.693 0.607 0.669 What would be the center line of a 3-sigma S chart?

You are a food specialist in a company that specializes inrefrigerated delicacies, and one of your brands requires beingmaintained at a temperature of 5°C. You determine averagewater activity (aw) at this temperature to be 0.2. One day, you are informed that the cooling systems onone of the delivery trucks carrying your company’s productsmalfunctioned while en route to its destination and it would notbe fixed until the next delivery. The driver has informed you thatthe temperature in the delivery bay of the truck is averaging55°C. You estimate a heat of sorption (Q) of 19 kJ/mol. Calculate the water activity of the brand at this elevatedtemperature and comment on it’s integrity. Should the deliverystill push through? Or should the products be recalled anddisposed
Using traditional methods, it takes 101 hours to receive a basic driving license. A new license training method using Computer Aided Instruction (CAI) has been proposed. A researcher used the technique with 100 students and observed that they had a mean of 102 hours. Assume the variance is known to be 16. A level of significance of 0.05 will be used to determine if the technique performs differently than the traditional method. Find the value of the test statistic. Round your answer to 2 decimal places. Enter the value of the test statistic.
XYZ Rural Bank implemented its initial attempts to manage the performances of its 150 employees. XYZ Rural Bank has 10 branches all over Zamboanga Peninsula and each branch is supervised by a branch manager and has 10-15 employees working directly under his supervision.
