a.

Summary Introduction

Interpretation: The expected numbers of jobs which are in queue with steady status along with number of jobs in the system have to be computed.

Concept Introduction:

FCFS basis- Normally, there is a process in attending the jobs or, customers. FCFS basis means attending a job or customer on First come first serve basis. In other words, the job/customer which/who comes first is attended first.

B.

Summary Introduction

Interpretation: The expected flow time along with the time spent in a queue with steady status have to be computed.

Concept Introduction:

Flow time: The time spent in a business process right from beginning to end is called the flow time. It is also called total processing time.

C.

Summary Introduction

Interpretation: The probability about the system being empty needs to be computed.

Concept Introduction:

Probability: Probability is the chance of an event occurring. Number of favorable outcomes must be divided by total number of possible outcomes to get the probability factor.

D.

Summary Introduction

Interpretation: The probability about the queue being empty needs to be computed.

Concept Introduction:

Probability: Probability is the chance of an event occurring. Number of favorable outcomes must be divided by total number of possible outcomes to get the probability factor.

e.

Summary Introduction

Interpretation: The probability about the flow time exceeding 10 minutes needs to be computed.

Concept Introduction:

Probability: Probability is the chance of an event occurring. Number of favorable outcomes must be divided by total number of possible outcomes to get the probability factor.

Suppose a coffee shop order and fulfillment process is configured simply as a single queue with two steps: wait and service. Customers enter, wait their turn, and then are served, by placing and receiving their order all at once. Suppose that an average of 10 customers per hour enter the coffee shop while the shop is open. On average, there are two customers waiting in line to place their orders. It takes an average of 2 minutes to go through the service step, that is, it takes 2 minutes to complete the second step of placing and receiving the order. In steady state, O The average wait time before placing an order is 12 minutes. O The average time between customer arrivals is 5 minutes. O None of the answers are correct. There is an average of one customer being served at a time. O The average total time to wait and be served is 15 minutes.
Suppose i am going to build a digital model for all 4 different products coming to awarehouse. All products first move to a temporary waiting area and then to inspectionmachines. There are 4 inspection machines to process each product respectively. Afterinspection, all products must move to next station for scanning before they are finallytransported to 4 racks.Products arrives exponentially with an average of 12 seconds. Processing times of inspectionmachines ars exponentially distributed with an average 6 seconds. Scanning time is fixed 4seconds.Simulation time is 50000s, Queue capacity is 10000.Suppose i need to redesign this process. How would it be possible to improve this system.Maybe identify the bottleneck by output analysis and propose improvement solution byadding additional object(s) or new automated resource to the original model will be possible?
