Question 20. The process map below shows the security process through an airport. Times are in minutes. The table shows the results of 50 SimQuick simulations for a two hour period. Review the process map and the simulation output. How many customers are expected to enter the process during the two hour period?
Question 21. In the airport security simulation, on average how long does it take for a customer to pass through the security if no additional security is needed?
Question 22. In the airport security simulation, on average how long does it take for a customer to pass through the security if additional security is needed?
Question 23. In the airport security simulation, on average how long does it take for a typical customer to pass through the security (this is a weighted average)?
Question 24. Management wants to study the drive-thru at a number of Burger Queen (BQ) restaurants during the peak hours of 11 A.M. to 2 P.M. The process works as follows. Cars arrive and line up to place an order. It's been observed that the time between car arrivals can be approximated by an exponential distribution with a mean of 2.3 minutes. The time to place an order is also roughly exponentially distributed and takes a mean of 2 minutes per car. Cars then move forward to a single window, at which they pay and pick up their order. The amount of time a car sits at the pay/pick-up window can be approximated by an exponential distribution with a mean of 2.2 minutes. The process map and SimQuick® simulation table are shown below. What is the average arrival rate per hour to the process?
Question 25. In the Burger Queen restaurant simulation, what is the service level for this process?
Question 26. In the Burger Queen restaurant simulation, on average how long does it take for a car (customer) to drive through the process?
Question 27. A simple project listing of five activities and their respective time estimates are presented below:
Using CPM, which activities make up the critical path?
Question 28. A company must perform a maintenance project consisting of seven activities. The activities, their predecessors, and their respective time estimates are presented below:
Using CPM, which activities make up the critical path?
Question 29. In the project network presented below, numbers on each arrow refer to the expected time and standard deviation in weeks for that particular activity. For example, "8,2" indicates an activity with an expected time of 8 and a standard deviation of two weeks.
What is the expected project duration?
Question 30. For the project network shown above, what is the probability that the project will be completed in 29 weeks?
