The times (in minutes)required on each machine are as follows:MachineComponentShaperGrinder6.4.The shaper is available for 120 hours, and the grinder is available for 110 hours. No more than200 units of component 3 can be sold, but up to 1000 units of each of the other components canbe sold. In fact, the company already has orders for 600 units of component 1 that must besatisfied.

4. CWD Business systems maintains a successful Telecom sales department for Top up call credit in which a clerk takes orders by telephone. If the clerk is occupied on one line, incoming phone calls to the department are answered automatically by an answering machine and asked to wait. As soon as the clerk is free, the party that has waited the longest is transferred and answered first. Calls come in at a rate of about 15 per hour. The clerk is capable of taking an order in an average of 3 minutes. Calls tend to follow a Poisson distribution, and service times tend to be exponential. The clerk is paid $15 per hour, but because of lost goodwill and sales, CWD loses about $30 per hour of customer time spent waiting for the clerk to take an order. Part B CWD is considering adding a second clerk to take calls. The store would pay that person the same $15 per hour. Using appropriate formula for the multiple channel model, answer the following questions: a. What is the probability that no…

14. Digital Controls, Inc. (DCI) manufactures two models of a radar gun used by police to mon- itor 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 3 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 re- quires 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 1080 min- utes 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…
19-33 Waiting times, manufacturing cycle times. The IVplast Corporation uses an injection molding ma- chine to make a plastic product, Z39, after receiving firm orders from its customers. IVplast estimates that it will receive 40 orders for Z39 during the coming year. Each order of Z39 will take 120 hours of machine time. The annual machine capacity is 6,800 hours. 1. Calculate (a) the average amount of time that an order for Z39 will wait in line before it is processed and (b) the average manufacturing cycle time per order for Z39.
HW1 Q1 Consider the emergency department of a hospital that operates as follows: Upon arrival, patients first wait in line for registration. Then, after registration, patients wait to see a triage nurse who classifies them as either critical or non-critical. After the triage nurse, critical patients go to the emergency care area waiting to be seen by a doctor while non-critical patients go to the routine care area where they wait to see a doctor. It is determined that there are, on average, 20 patients registering or waiting to be registered, 5 patients being seen or waiting to be seen by the triage nurse, 15 critical patients being seen or waiting to be seen by a doctor in the emergency area, and 20 non-critical patients being seen or waiting to be seen by a doctor in the routine care area, Assuming that 20 patients arrive every hour and that 75% of the patients are non-critical, how many minutes does a patient spend on average in the emergency department of the hospital? Average time…

17-36 Weighted-average method. Larsen Company manufactures car seats in its San Antonio plant. Each car seat passes through the assembly department and the testing department. This problem focuses on the assembly department. The process-costing system at Larsen Company has a single direct-cost cat- egory (direct materials) and a single indirect-cost category (conversion costs). Direct materials are added at the beginning of the process. Conversion costs are added evenly during the process. When the assembly department finishes work on each car seat, it is immediately transferred to testing. Larsen Company uses the weighted-average method of process costing. Data for the assembly depart- ment for October 2017 are as follows: Physical Units (Car Seats) Direct Conversion Materials $1,250,000 Costs $ 402,750 Work in process, October 1 Started during October 2017 Completed during October 2017 Work in process, October 31b Total costs added during October 2017 5,000 20,000 22,500 2,500…
