Consider the following four-step assembly operation with quality problems. All resources are staffed by one employee.. The first resource has a processing time of 5 minutes per unit.. The second resource has a processing time of 6 minutes per unit.. The third resource has a processing time of 3 minutes per unit. With a 30 percent probability, the flow unit coming out of the thirdresource has to be reworked. In that case, the operations at the first, second, and third resources are repeated. You can assumethat (a) rework always succeeds (.e., a unit going through the rework loop will always work after the third resource) and (b) theprocessing times for units in rework are the same as for regular units.• The fourth resource has a processing time of 4 minutes per unit.a.

Dr. Gulakowicz is an orthodontist. She estimates that adding two new chairs will increase fixed costs by $149,000, including the annual equivalent cost of the capital investment and the salary of one more technician. Each new patient is expected to bring in $3,040 per year in additional revenue, with variable costs estimated at $1,030 per patient. The two new chairs will allow Dr. Gulakowicz to expand her practice by as many as 205 patients annually. How many patients would have to be added for the new process to break even?

company has introduced a process improvement that reduces processing time for each unit;output is increased by 40 percent with less material, but two additional workers are required.Under the old process, five workers could produce 1800 units per hour. Labor costs are $20/hour, and material input was previously $15/unit. For the new process, material is now $12/unit. *Overhead is charged at (1.4XLABOR COST + 500). *Finished units sell for $80 each. QUESTION: What increase in productivity is associated with the process improvement?
Rock View Restaurant is a new fast-food restaurant chain.

3- The first part of description is introduction. The question is related to the second paragraph. Answer the question regarding the flow process chart. Description: Assume that a factory contains a forge shop, machine shop, and finishing department. These departments produce most majority of the parts. Due to this issue, the factory is laid out as three large square rooms. The rectangle runs from north to south, with the forge shop on the south end and the finishing department on the north end. Large doors are located on the south wall for work entering the factory and on the north wall for finished products exiting the factory. In this case, the raw material is a steel billet that is purchased from a steel wholesale supplier. The billets arrive in pallet loads of 50 billets at the shipping and receiving department, which is a building that is located 20 ft from the south wall door of the factory. The shipping and receiving department inspects the parts and sends them by forklift…
