Question
Scenario E.1
SimQuick is being used to simulate the following bank process:
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:
| Element Types | Element Names | Statistics | Overall 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 time in buffer | 9.75 | ||
| Work Station | Teller | Work cycles started | 37.83 |
| Fraction time working | 0.94 | ||
| Buffer | Served Customers | Final inventory | 36.85 |
Use the information in Scenario E.1. On average, approximately how many customers were waiting in line during the 2-hour simulation period?
A) 5
B) 4
C) 3

Q:
Jackson Sheds has four different warehouse configurations under study, ranging from four warehouses to seven warehouses (only integer values). Each warehouse has a capacity of 200 units and costs $200 to maintain over the course of a year. Demand can range from 1,000 units per year up to 2,000 units in increments of 250 units. If the system warehouse capacity is sufficient to handle the year's demand, then the per unit cost is $2 per unit, but if the warehouse capacity is insufficient, the per unit cost for each unit in excess of system capacity is $3 per unit. The likelihood for each possible demand is shown in the table. Likelihood

Q:
The VP of Finance studied the printing costs at the university and knew it was time for bold, decisive action. The annual fixed cost of printing at the school was $850,000 and the per-page cost was one cent. Fortunately, his brother-in-law happened to own a company that would lease the printers to the university for only $600,000. The only issue to be decided was what the per-page cost would be for the leased printers. On average, the university had been printing about 10,000,000 pages per year. What would a break-even per-page printing cost be given the average printing volume?

7 Costs associated with operations are as follows:
Wages = $2,000 per worker per month
Hiring cost = $1,000 per worker
Layoff cost = $1,500 per worker
The current workforce level is 10 workers. Use the spreadsheet approach and the preceding data to answer the following questions:
a. What is the total cost of a staffing plan, including the cost of regular wages, hiring, and layoffs using a chase strategy with hiring and layoffs, but no overtime?
b. What is the total cost of the staffing plan, using a level strategy in which no overtime is allowed and the undertime paid for?
c. Suppose that overtime is allowed up to 25% of the regular-time capacity, and that overtime wages are 150% of the regular-time rate. What is the total cost of the level strategy with overtime and undertime that also minimizes undertime?

Q:
The single milling machine at Fred's Manufacturing was severely overloaded last year. The plant operates 8 hours per day, 5 days per week, and 50 weeks per year. Management prefers a capacity cushion of 20 percent. Two major types of products are routed through the milling machine. The annual demand for product A is 4,000 units and 3,000 units for product B. The batch size for A is 20 units and 30 units for B. The standard processing time for A is 0.5 hours/unit and 0.8 for B. The standard setup time for product A is 2 hours and 8 hours for product B. How many new milling machines are required if Fred's does not resort to any short-term capacity options?

Q:
Refer to the bank process model. The bank's process improvement group has developed a number of process and technology changes that will improve the Teller's process rate per customer from a mean of 3.0 minutes to 2.5 minutes (standard deviation remains at 0.5 minutes). The Bank Manager wants to determine if the improved process rate, along with the special promotion for new customers, will allow the "arrive and immediately leave" rate and average customer wait time in line achieved to still be met (12% balk rate, 9.95 minutes in line). If so, the manager will implement the process and technology changes and allow the special promotion to proceed. Using SimQuick, estimate the new arrive and immediately leave rate and average time in line. What decision should the manager make?

Q:
SimQuick is to be used to simulate the following bank process: Customers arrive at the Entrance Door of the bank with an average time between arrivals of 2.5 minutes.

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 flowchart is used to count the number of customers processed during the simulation period. A 2-hour period is to be simulated and the simulation should be repeated 30 times. Determine:
a) The number of customers served during the 2-hour period;
b) The percentage of customers who arrived at the bank and left because the buffer line was full;
c) The utilization of the teller (% of time working) during the 2-hour period;
