Question

4. KraftyCity is a large retailer that sells power tools and other hardware supplies. One of its
products is the KraftyMan workbench. Information on the workbench is as follows:
1,200
$15 per year
=
: $200 per order
Annual demand =
Holding cost
Ordering cost
=
a. (*) What is the economic order quantity for the workbench?
b. (**) Suppose that KraftyCity has to pay $50 per workbench for orders under
200 but only $42 per workbench for orders of 201 or more. Using the
information provided in problem 30-40, what order quantity should
KraftyCity use?
c. (*) The lead time for KraftyCity workbenches is 3 weeks, with a standard
deviation of 1.2 weeks, and the average weekly demand is 24, with a standard
deviation of 8 workbenches. What should the reorder point be if KraftyCity
wants to provide a 95% service level?
d. (**) Now suppose the supplier of workbenches guarantees KraftyCity that the
lead time will be a constant 3 weeks, with no variability (i.e., standard
deviation of lead time = 0). Recalculate the reorder point, using the demand
and service level information in problem 3-6. Is the reorder point higher or
lower? Explain why.

A local firm is planning its workforce and production levels over the next year. The firm makes a variety of microprocessors and uses sales dollars as its aggregate production unit. Based on orders received and sales forecasts provided by the marketing department, the estimate of dollar sales for the next year by month is as follows: Month Production Days Predicted Demand(in $10,000) Month Production Days Predicted Demand(in $10,000) January 20 595 July 20 410 February 19 225 August 21 130 March 22 565 September 19 405 April 18 205 October 23 315 May 21 230 November 21 355 June 22 120 December 18 350 Inventory holding costs are based on a 25% annual interest charge. It is anticipated that there will be 675 workers on the payroll at the end of the current year and inventories will amount to $120,000. The firm would like to have at least $100,000 of inventory at the end of December…
In 1997 Fuller and coworkers at Texas A&M University estimated the operating costs of cotton gin plants of various sizes. The operating costs of the next to the smallest plant is shown in the following table. x 2000 4000 6000 8000 10000 12000 y 163,200 230,480 301,500 376,160 454,400 536,400 Here x is the annual number of bales produced, and y is the dollar total cost. (Use 4 decimal places in your answer.)A. Determine the best fitting line using least squares. Also determine the square of the correlation coefficient.The best fitting line is C(x) = .The square of the correlation coefficient is r2 = .B. The study noted that revenue was $63.25 per bale. At what level of production will this plant break even?The revenue equation is R(x) = The profit equation is P(x) = The production will break even when bales are produced.C. What are the profits or losses when production is 3000 bales? 4000 bales? (Round to the nearest cent.)When…
An entrepreneur who owns and operates two businesses (A and B) would like to analyze their profitability. They would like your help in the analysis. They give you the annual net profit (in thousands of $) for each business from 2008-2020. Table 1: Annual Net Profits for Businesses A and B Business Year Profit Business Year Profit 2008 -50 2008 -10 2009 57 2009 30 2010 71 2010 27 2011 64 2011 22 2012 60 2012 21 2013 50 2013 20 A 2014 41 2014 24 2015 59 2015 24 2016 71 2016 32 2017 71 2017 36 2018 74 2018 37 019 81 20 40 2020 97 2020 49 a. Suppose you want to graph the distribution of profits. Explain why using only one stem- plot might not be optimal for the analysis. b. Describe the correct stemplot to use. Generate this stemplot. Explain your steps. What can you say about the distribution from this stemplot? c. When are stemplots useful? And why is that? d. Suppose that instead of having 26 observations you have 200 observations. What graph should you generate? e. What other type of…
Given the Information in the below table's, calculate the total cost if you choose the: i) Level Strategy with average production per day. ii) Chase strategy for the production. Month Expected Demand Production Days Jan 600 22 Feb 800 18 March 900 21 April 1000 21 Inventory carrying cost $5 per unit per month Subcontracting cost per unit $20 per unit Average Pay rate $10 per hour ($80 per day) Over time Pay rate $17 per hour (above 8 hours) Labour-hours to produce a unit 1.6 hours per unit Cost of increasing daily production rate $300 per unit Cost of decreasing daily production rate $600 per unit
Replace the March demand forecast 510 by C. During a 46-day period when there were 120 workers, the firm produced 1,700,000 cookies. Assume that there are 100 workers employed, and C cookies in inventory at the beginning of month 1 (January). Further assume that the inventory carrying cost cI = $0.10/cookie/month, employee hiring cost cH = $100/work, and cost of firing one worker cF = $200/worker. It is required that the inventory level at the end of month 12 (December) is 2C. use the Constant workforce plan (level strategy): Find the minimum constant workforce needed to meet all monthly demands (i.e, back order not allowed). Computer the total cost including employee hiring or firing cost (which occurs only at the beginning of month 1), and inventory carrying cost.
