For the production of part R-193, two operations are being considered. The capital investment associated witheach operation is identical.Operation 1 produces 2,100 parts per hour. After each hour, the tooling must be adjusted by the machineoperator. This adjustment takes 15 minutes. The machine operator for Operation 1 is paid $24 per hour (thisincludes fringe benefits).Operation 2 produces 2,350 parts per hour, but the tooling needs to be adjusted by the operator only onceevery two hours. This adjustment takes 45 minutes. The machine operator for Operation 2 is paid $13 perhour (this includes fringe benefits).Assume an 8-hour workday. Further assume that all parts produced can be sold for $0.35 each.a. Should Operation 1 or Operation 2 be recommended?b. What is the basic tradeoff in this problem?

Answered: For the production of part R-193, two…

Cablesplice, Inc.'s manufacturing process consists of five steps: making con- ductors, adding insulation, adding sheathing, irradiation, and printing and coil cuttingUnits are measured in meters. In 970,000 meters of cable, 700 defects were found in the conductors, and 75,000 defects were found in the insulation. In 440,000 meters of cable, 8,930 defects were found in the sheathing, and no defects were found in the remaining two steps. (a) Find DPU and the dpmo, and (b) the sigma level for each process step.
A machine makes two components; call them types A and B. It takes 630 seconds to switch production between the component types. During that time, no production occurs. When in production, each unit of A or B requires 0.5 second to be completed. The two components, A and B, are combined in an assembly process to make a final product; call it C. The assembly step can combine the two components into 1 unit every 4 seconds, or 15 units per minute. Suppose the machine rotates between one batch of 2,520 units of A and 2,520 units of B. In that case, what is the capacity of the machine in component pairs per minute, where a component pair is one unit of A and one unit of B?

A startup company is considering making a part by injection molding. The part is moderately complex and the volume of the part is about 10 cubic centimeters. Assume that the part is designed for injection molding and can be made with a two part mold. The company needs to make 250,000 parts made from ABS plastic. Once the mold is made it will take a worker 1 minute to make one part using the injection molding machine. The company will use contract manufacturing to produce the parts. Estimate the cost per part and explain how you came up with the number. (If you are stuck look at the Contract Manufacturing Cost per Unit section. Also keep in mind that there is no exact right answer, the goal is to come up with a reasonable estimate.) Contract Manufacturing Cost per Unit: It’s not uncommon to hire another company to perform some or all the manufacturing for a product. To estimate the cost use ((Cost of Parts and Materials) + (man hours) × $40)/.75
Hammond Inc. has analyzed the setup time on its computer-controlled lathe. The setup requires changing the type of fixture that holds a part. The average setup time has been 135 minutes, consisting of the following steps: Step Time (in minutes) Turn off machine and remove fixture from lathe 13 Go to tool room with fixture 15 Record replacement of fixture to tool room 18 Return to lathe 20 Clean lathe 17 Return to tool room 20 Record withdrawal of new fixture from tool room 12 Return to lathe 15 Install new fixture and turn on machine 8 Total setup time 138 Why should management be concerned about improving setup time? What do you recommend to Hammond Inc. for improving setup time? How much time would be required for a setup, using your suggestion in (b)?
A cell-phone repair shop consists of three processes. Step 1 requires 4 minutes per unit, step 2 requires 6 minutes per unit and step 3 requires 2 minutes per unit. 40% of units that complete the third step require rework, which means those units must start the process over at step 2 (processing times are the same for units being reworked) and rework is always successful. Demand at the shop is 0.8 units per minute. Instruction: Round your answer to three decimal places. What is the capacity of the shop (in units per units per minute)? units per minute

Sturgill Manufacturing Inc. needs to predict the numbers of machines and employees required to produce its planned production for the coming year. The plant runs three shifts continuously during the workweek, for a total of 120 hours of capacity per week. The shop efficiency (the percent of total time available for production), which accounts for setups, changeovers, and maintenance, averages 70% with a standard deviation of 5%, which reduces the weekly capacity. Six key parts are produced, and the plant has three different types of machines to produce each part. The machines are not interchangeable as they each have a specific function. The time to produce each part on each machine varies. The mean time and standard deviation (in hours) to produce each part on each machine are shown below: Mean Time Part Type Machine A Machine B Machine C 1 3.5 2.6 8.9 2 3.4 2.5 8 3 1.8 3.5 12.6 4 2.4 5.8 12.5 5 4.2 4.3 28 6…
