Please solve all and explain each step For the production of part R-193, two operations are being considered. The capital investment associated witheach operation is identical.Operation 1 produces 1,600 parts per hour. After each hour, the tooling must be adjusted by the machineoperator. This adjustment takes 10 minutes. The machine operator for Operation 1 is paid $19 per hour (thisincludes fringe benefits).Operation 2 produces 1,850 parts per hour, but the tooling needs to be adjusted by the operator only onceevery two hours. This adjustment takes 30 minutes. The machine operator for Operation 2 is paid $11 perhour (this includes fringe benefits).Assume an 8-hour workday. Further assume that all parts produced can be sold for $0.40 each.a. Should Operation 1 or Operation 2 be recommended?b. What is the basic tradeoff in this problem?a. The profit using Operation 1 is $ 4,237 per day. (Round to the nearest dollar.)The profit using Operation 2 is $ 4,648 per day. (Round to the nearest dollar.)Operation 2 should be chosen.b. Choose the correct answer below.A. A higher production for Operation 2 is being traded off for a higher tool changing time (downtime).B. A higher production for Operation 1 is being traded off for a lower tool changing time (downtime).OC. A higher production for Operation 2 is being traded off for a lower tool changing time (downtime).D. A higher production for Operation 1 is being traded off for a higher tool changing time (downtime).

Answered: operator. This adjustment takes 10…

A recurring maintenance job in a factory is being done by a three-man crew. Due to the nature of the job and space limitations, it was observed that two of the men were idle 37% of the time; one of the men was also idle an additional of the time, and at any given time only one man was required. The men were each paid P24.00 per hour. Each time the job was performed a set of tools and equipment with a value equivalent to P36.00 per hour was used. If the three-men crew could complete the work in 5 hours, which crew size would be the most economical
3.Consider the following three-stage production process of glass ceramics. The process is experiencing severe quality problems related to insufficiently trained workers. Specifically, 20 percent of the parts going through operation 1 are badly processed by the operator. Rather than scrapping the unit, it is moved to a highly skilled rework operator, who can correct the mistake and finish up the unit completely within 15 minutes. The same problem occurs at station 2, where 10 percent of the parts are badly processed, requiring 10 minutes of rework. Station 3 also has a 10 percent ratio of badly processed parts, each of them requiring 5 minutes by the rework operator. a)What is the utilization of station 2 if work is released into the process at a rate of 5 units per hour? b)Where in the process is the bottleneck? Why? (Remember, the bottleneck is the resource with the lowest capacity, independent of demand.)
A process has seven elements composed of combination of worker and machine. Elements A, B, D, and F are worker-controlled while elements C and E are machine controlled. Element G is a worker-controlled irregular element performed every five cycles Machines are idle during elements A, D, and G. Two units are produced every cycle. Below are the observed time (in minutes) and performance rating of each element. Work Element Observed Time (in minutes) Performance Rating A 0.75 115% B 1.20 120% C 1.40 N.A. D 1.05 90% E 1.25 N.A.

The Tesla Model S, one of the most sought-after luxury cars, is produced in Tesla’s Freemont factory in California. The production process can be broken up into the following subprocesses. Stamping: In the stamping process, coils of aluminum are unwound, cut into level pieces of sheet metal, and then inserted into stamping presses that shape the metal according to the geometry of the Model S. The presses can shape a sheet of metal in roughly 6 seconds. Subassembly: The various pieces of metal are put together using a combination of joining techniques,including welding and adhesion. This creates the body of the vehicle.Paint: The body of the vehicle is then moved to the paint shop. After painting is completed, the body moves through a 350° oven to cure the paint, followed by a sanding operation that ensures a clean surface. General assembly: After painting, the vehicle body is moved to the final assembly area. Here, assembly workers and assembly robots insert the various subassemblies,…
Data Products, Inc., packages and distributes a variety ofpersonal computer-related products. A time study hasbeen conducted for a job packaging 3.5-inch personalcomputer diskettes for shipment to customers. The jobrequires a packager to place 20 diskettes in a rectangularplastic bag, close the bag with a twist tie, and place thefilled bag into a bin, which is replaced by another workerwhen it is filled. The job can be broken into four basic elements. The elemental times (in minutes) were ob-tained from the time study for 10 job cycles shown in the following table. a. Using an allowance factor of 16%, determine the stan-dard time for this job. b. Determine the number of cycles for this time studysuch that the company would be 95% confident that theaverage time from the time study is within 4% of thetrue average cycle time.
Assume that General Dynamics, which manufactures high-technology instruments for spacecraft, is considering the sale of a navigational unit to a government agency in India that wishes to launch its own communications satellite. The government agency plans to purchase 8 units, although it would also consider buying 16 units. General Dynamics has started a chart relating labor time required to units produced. Unit Produced (X) Time Required toProduce the Xth Unit 1 10,000 hours 2 8,000 hours 4 6,400 hours 8 ? 16 ? Required: a. Compute the labor time required to produce 8 and 16 units.b. Assume that labor time costs $125 per hour. Compare the cost of producing the 1st unit to the cost of producing the 16th unit. What is the percentage of the cost of the 16th unit to the cost of the 1st unit?
William Beebe owns a small shoe store. He has 10 pairs of shoes that requireresoling and polishing. He has a machine that can resole one pair of shoes at atime, and the time required for the operation varies with the type and condition of theshoe and the type of sole that is used. Shoes are polished on a machine dedi-cated tothis purpose as well, and polishing is always done after resoling. His assistant generally does the polishing while Mr. Beebe does the resoling.

Charles Lackey operates a bakery in Idaho Falls, Idaho. Because of its excellent product and excellent location, demand has increased by 25% in the last year. On far too many occasions, customers have not been able to purchase the bread of their choice. Because of this size of the store, no new ovens can be added. At a staff meeting, one employee suggested ways to load the ovens differently so that more loaves of bread can be baked at one time. This new process will requrie that the ovens be, loaded by hand, requiring additional manpower. This is the only production change that will be made in order to meet the increased demand. The bakery currently makes 1,600 loaves per month. Employees are paid $8 per hour. In addition to the labor cost, Charles also has a constant utility cost per month of $700 and a per loaf ingredient cost of $0.50. Current multifactor productivity for 640 work hours per month= .242 loaves/dollar (round your response to three decimal places). After increasing…
