One of the new thrusts of quality control management is to examine the process by which a product is produced. This approach also applies to paperwork. In industries where large long- term projects are undertaken, days and even weeks may elapse as a change order makes its way through a maze of approvals before receiving final approval. This process can result in long delays and stretch schedules to the breaking point. Suppose a quality control consulting group claims that it can significantly reduce the number of days required for such paperwork to receive an approval. In an attempt to "prove" its case, the group selects five jobs for which it revises the paperwork system. The following data show the number of days required for a change order to be approved before the group intervened and the number of days required for a change order to be approved after the group instituted a new paperwork system. Before After 12 8 3 10 16 8 8 Use alpha = 0.05 to determine whether there was a significant drop in the number of days required to process paperwork to approve change orders. Assume that the differences in days are normally distributed. The observed value of t for this problem is 4.78 2.05 4.87 -4.78 -2.05

Describe the results of your two graphs as they compare to the movement of demand. Be specific. Choosing between the three-period and the five-period forecasts, which length of averaging would you use as a purchasing manager of Greenfield’s Tannery? Be sure to factor in the cumulative forecast errors in your answer. Also, make sure you include some rationale about why you are picking the method you do for this particular business. So for example, does picking one method over the other have any impact on how much inventory they will have on hand to meet customer demand? What happens when the demand drops? Which method better supports that?
Assume a company reported the following results: Sales Variable expenses Contribution margin Fixed expenses Net operating income $ 400,000 260,000 140,000 40,000 100,000 Average operating assets $ 500,000 If the company's minimum required rate of return on average operating assets is 16%, its residual income would be: Multiple Choice О $20,000. $21,000. $22,000. $23,000.
The company has data on demand and factory capacity for the next 4 months as in the table. Unit cost with regular time $ 24, overtime cost $ 28, on subcontract $ 34. Storage costs $ 2 per unit per month; backorders cost $ 5 per unit per month. Initial inventory is as many as 120 units, and it is expected that by the end of July there will be an inventory of 100 units. April May June July Demand 460 450 480 480 Regular Capacity 370 370 380 380 Overtime Capacity 60 60 60 60 Subcontract Capacity 30 30 30 30 Use the transportation method to optimize the aggregate plan. Determine the production cost each month and the total cost for 4 months
Homework #8 Having the ability to monitor a process is critical in maintaining quality but also managing staff morale and/or fatigue. Please use the information below to answer the questions. Warehouse 36 produces birdhouses for Company X. Due to an illness that swept through the factory, Warehouse 36 is behind in production. In order to "catch up" to their predicted quota, the supervisor plans to work 12 hour shifts for 21 days. Over the course of the three-week period, production was steady and then began to decrease resulting in not meeting the goal of 340 units per day. Based on the information provided below, when did production begin to fall? At what point could a day off have prevented a production decrease? How do you know? Provide a visual display of data that shows the average, upper/lower class limits and daily production. (Hint - statistical process control) How could you have adjusted the schedule to reach the desired result? Days Production 1 2 3 4 5 LN34567 99 6 345 7…

You are the VP, Advertising for “Yo’ Mama” brand, a fashion label that caters to the young, trendy crowd with an urban, hip-hop image. While your customer base has traditionally been largely African-American, you have recognized a tremendous influx of Hispanic consumers into your market. You are preparing for next week’s annual budget meetings and you have decided to recommend an Hispanic-focused advertising campaign if the average monthly per store sales to Hispanic customers are at least the same as the average monthly per store sales to African-American customers in a sample of typical stores (sales data given below). Using an alpha of .05 and the 5-step hypothesis testing process, what will you recommend? Hint: Think about how many data points you actually have.
Two competing companies produce mobile phones. Company A starts production at 1000 phones per week and plans to increase output by 200 each week. Company B starts production with 500 phones per week and plans to increase output by 20% each week. (a) Calculate the weekly production in weeks 1; 5; 10; 15. Plot the graph of weekly output for each producer on the same diagram (use Excel, if available). Estimate the week in which the output is the same for both firms. (b) Calculate the total production during the first 15 weeks for each firm.
