Assuming your company is producing Apple and Samsung phone cases. It is required to process in the assembly and paint shops to make either phone case. It takes 1/60 of a day and 1/40 of a day to paint an Apple case and a Samsung case in the paint shop, respectively. It takes 1/50 of a day to assemble either type of case in the assembly shop. An Apple phone case and a Samsung phone case yield profits of $300 and $220, respectively, per case sold. What is a maximum-profit daily production plan for your company?

Justin is a carpenter and makes furniture which he sells via the internet. He needs a new machine with steel attachments to speed up the drilling process for his work. He contacts Fixing and Building Machines Ltd who recommends a machine which they claim is more than 10 times quicker and stronger than his old machine. Justin goes into Fixing and Building Machines Ltd. Before paying for the machine, he sees a sign on the wall behind the counter that has the words “Important Information: READ BEFORE PURCHASE! Fixing and Building Machines Ltd accepts no liability.....” in bold, red print at the top. However, the sign is falling down from the wall and the rest of the words are obscured by a large plant. Had Justin been able to read the rest of the sign, he would have read “....for loss howsoever caused.” Justin signs a document, buys this machine and takes it with him. When he tried it he found it to be no quicker than his old one and the attachments broke. He also found that it started…
Syntech makes digital cameras for drones. Their basic digital camera uses $80 in variable costs and requires $1,400 per month in fixed costs. Syntech sells 100 cameras per month. If they process the camera further to enhance its functionality, it will require an additional $50 per unit of variable costs, plus an increase in fixed costs of $1,000 per month. The current price of the camera is $150. The marketing manager is positive that they can sell more and charge a higher price for the improved version. At what price level would the upgraded camera begin to improve operational earnings? Price to be charged $fill in the blank 1

Spartan Castings must implement a manufacturing process that reduces the amount of particulates emitted into the atmosphere. Two processes have been identified that provide the same level of particulate reduction. The first process is expected to incur $350,000 of fixed cost and add $50 of variable cost to each casting Spartan produces. The second process has fixed costs of $150,000 and adds $90 of variable cost per casting.a. What is the break-even quantity beyond which the first process is more attractive?b. What is the difference in total cost if the quantity produced is 10,000?
A firm has redesigned its production process so that it now takes 10 hours for a unit to be made. Using the old process, it took 15 hours to make a unit. If the process makes one unit each hour on average and each unit is worth $1,500, what is the reduction in work-inprocess value?

A bicycle component manufacturer produces hubs for bike wheels. Two processes are possible for manufacturing, and the parameters of each process are as follows: Process 1 Production rate Daily production time Process 2 35 parts/hour 4 hours/day 20% 15 parts/hour 7 hours/day 9% Percent parts rejected Assume that the daily demand for hubs allows all defect-free hubs to be sold. Select the process that maximizes profit per day if each part is made from $4 worth of material and can be sold for $30. Both processes are fully automated, and variable overhead cost is charged at the rate of $40 per hour.
A firm has redesigned its production process so that it now takes 10 hours for a unit to be made. Using the old process, it took 15 hours to make a unit. If the process makes one unit each hour, on average, and each unit is worth $1,500, what is the reduction in working process value?
Digital Controls, Inc. (DCI), manufactures two models of a radar gun used by police to monitor the speed of automobiles. Model A has an accuracy of plus or minus 1 mile per hour, whereas the smaller model B has an accuracy of plus or minus miles per hour. For the next week, the company has orders for 100 units of model A and 150 units of model B. Although DCI purchases all the electronic components used in both models, the plastic cases for both models are manufactured at a DCI plant in Newark, New Jersey. Each model A case requires 4 minutes of injection-molding time and 6 minutes of assembly time. Each model B case requires 3 minutes of injection-molding time and 8 minutes of assembly time. For next week, the Newark plant has 600 minutes of injection-molding time available and 1,080 minutes of assembly time available. The manufacturing cost is $10 per case for model A and $6 per case for model B. Depending upon demand and the time available at the Newark plant, DCI occasionally…
The one in bold, I already sold. Spartan Castings must implement a manufacturing process that reduces the amount of particulates emitted into the atmosphere. Two processes have been identified that provide the same level of particulate reduction. The first process is expected to incur $340,000 of fixed cost and add $40 of variable cost to each casting Spartan produces. The second process has fixed costs of $100,000 and adds $70 of variable cost per casting. a. What is the break-even quantity beyond which the first process is more attractive? The break-even quantity is 8000 castings. b. What is the difference in total cost if the quantity produced is 5,000? The total cost of process 1 is greater. Find the difference in total cost?
Can you do the calculations in Excel file showing all the work? You are a planner at a small distribution warehouse. Historically, the warehouse has targeted fulfilling 10 orders per hour for planning purposes. However, as the diversity of products has expanded, as well as the size of orders, this target has proven to be unreliable, as the orders are continually behind schedule and customers are complaining about late deliveries. Your supervisor has tasked you with determining a better target so that the warehouse may provide better delivery estimates to customers for their orders. Over the past week you gathered data for the number of orders fulfilled each day. This data is shown in the following table. Day Monday Tuesday Wednesday Thursday Friday Orders 88 64 72 56 80 A. Assuming 8 hours of operations each day, what is the mean and standard deviation for orders fulfilled per hour? The following table may help with these calculations. N is the total…
You are in charge of a large assembly shop that specializes in contract assignments. One of your customers has promised to award you a large contract for the assembly of 1,000 units of a new product. The suggested bid price in the contract is based on an average of 20 hours of direct labor per unit. You conduct a couple of test assemblies and find that, although the first unit took 50 hours, the second unit could be completed in just 40 hours. a. How many hours do you expect the assembly of the third unit to take? b. How many hours do you expect the assembly of the 100th unit to take? c. Is the contract’s assumption about the average labor hours per unit valid or should the price be revised?
