- A lab provides ultrasound service to patients. The service process consists of two steps: 1. Registration. Performed by a receptionist (Salary rate = $25/hr; Process time = 6 minutes/patient) 2. Ultrasound scan. Performed by a technician (Salary rate = $30/hr; Process time = 20 minutes/patient) Note that the ultrasound images need to be read by radiologists, but we assume that they have an ample capacity and thus will not model the role in the service process. Currently, the lab has 2 receptionists and 3 technicians. The manager anticipates demand to grow to 14 patients/hr in the near future. Thus, he plans to hire more receptionists and/or technicians to increase the service capacity to at least 14 patients/hr. What would be the extra payroll cost (in dollars per hr)?C&A Candy produces two kinds of gumdrops: regular and sugar-free. The data on these gumdrops are given below: Regular Sugar-Free 30 10 60 30 80 80 Demand (lbs per hour) Changeover time (min) Production rate (lbs per hour) C&A first makes 60 pounds of regular gumdrops, then 20 pounds of sugar-free gumdrops, and then repeats this sequence. What is the utilization of the production process? Multiple Choice O O O 25% 20% 50% 40%The OR is available for 12 hours a day; the hospital has decided to not perform any procedures between 7pm and 7am. This time is equally divided across three surgeons. The standard procedure time for the knee surgery done at the clinic is 1h. The cleaning and housekeeping that needs to happen after each procedure takes 20 minutes. Almost all of this time could be saved if the cleaning crew were notified earlier on. 10 minutes are spent on patient preparation / anesthesia work before each procedure. (Note: this is not part of the 60-minute procedure time). Proposals have been evaluated to move these 10 minutes to outside the OR, and there exists no medical reason that would prohibit doing this.) A surgeon only starts a case if all of the work associated with the case (preparation, procedure, and cleaning) can be completed in the 4h allotted to each surgeon. Surgeons never start BEFORE their allotted time. Though the clinic aims to operate 7 days a week, holidays, vacation, and…
- Additional Algo 4-9 Add N workers Drivers are trained in a process with two resources (workers in each resource work independently). The processing time (per worker) of the first resource is 38 hours. The processing time (per worker) of the second resource is 71 hours. The first resource has 4 workers and the second resource has 7 workers. Assume 4 workers are added to the bottlenck resource. Instruction: Round your answer to three decimal places. What would be the capacity of this process? drivers per hourWhich of the following most directly expresses the motivation behind the expression "Do not block the bottleneck"? Multiple Choice O O O If the bottleneck has nothing to work on, the overall capacity of the process will be lower than it could be. If the bottleneck is prevented from working (e.g., it has nowhere to put its output), the overall capacity will be reduced. Blocking the bottleneck will increase the coefficient of variations of the arrival process, which decreases capacity. Blocking the bottleneck increases inventory turns, which increases the annual holding costs. It is not good to block the bottleneck because there are economies of scale in inventory management.Wally's Widget Warehouse takes orders from 7 A.M. to 7 P.M. The manager wants to analyze the process and has provided the following process flow diagram. There are three steps required to ship a customer order. The first step is to take the order from a customer. The second step is to pick the order for the customer, and then they have to pack the order to ready it for shipping. The order-taking step works at a maximum rate of 100 customer orders per hour. Order picking works at a maximum of 75 per hour, and packing works at 60 per hour. Customers Order Taker 100 Customers/ hour Current maximum output Pick orders Pack orders Customer Orders Pick Orders 75 Customers/ hour hours hours Picked Orders Wally wants to figure out the following. a.
