Scenario E.1 SimQuick is being used to simulate the following bank process: Entrance Door Buffer Line Work Station Teller Buffer Served Customers Customer arrivals at the Entrance Door of the bank with an average time between arrivals of 2.5 minutes. The Line Buffer holds 6 customers. If a customer arrives and the buffer line is filled, the customer leaves. The Work Station Teller's processing time per customer is normally distributed, with a mean of 3.0 minutes and a standard deviation of 0.5 minutes. The Served Customer Buffer in the flow chart is used to count the number of customers processed during the period simulated. A 2-hour period was simulated. The SimQuick simulation is run, and the results are as follows: Overall Element Types Element Names Statistics Means Entrance Door Objects entering process 41.80 Objects unable to enter 6.23 Service level 0.87 Buffer Line Objects leaving 37.83 Final inventory 3.98 Minimum inventory 0.00 Maximum inventory 5.85 Mean inventory 3.08 Mean…
A customer visits a restaurant and experienced good service. Next week again he visited the same restaurant with his family and finds a difference in service rendered by the waiter in the restaurant. In this situation which characteristic of service is observed? of O a. Inseparability O b. Intangibility Oc Perishability O d. Heterogeneity tion
An average of 1200 parts arrive to the EP chamber during an 8-hour workday. Each part goes through two stages of processing. At each stage, a single product is processed at a time, and processing takes an average of 15 seconds at the first station and 12 seconds at the second station. Inter-arrival times and service times are exponentially distributed. At the end of the second step, the product goes through a quality check. 5% of the parts fail the quality check and are sent back to the second stage of service. Parts exit the system only after they pass the quality check. Ignoring the time required to perform the quality check or in moving the part through the facility, what is the average cycle time for parts?

Safety regulations require that the time between airplane takeoffs (on the same runway) will be at least 3 minutes. When taking off, the run time of an airplane on the runway is 33 seconds. Planes are on average waiting 6 minutes and 48 seconds for takeoff. On average there are 16 planes taking off per hour. How many planes are either on the runway or waiting to take off? Round your answer to 2 decimal places.
Failsafe Textiles employs three highly skilled maintenanceworkers who are responsible for repairing the numerous in-dustrial robots used in its manufacturing process. A workercan fix one robot every 8 hours on average, with an exponen-tial distribution. An average of one robot fails every 3 hours,according to a Poisson distribution. Each down robot coststhe company $100.00 per hour in lost production. A newmaintenance worker costs the company $80.00 per hour insalary, benefits, and equipment. Should the manager hireany new personnel? If so, how many people? What would yourecommend to the manager, based on your analysis?
