- In short, define three cases in which the first-in, first-out (FIFO) concept in queuing analytics is not valid.What is the theoretical distribution which describes the service time in queuing theory? A. Negative exponential B. Six sigma limits C. Bell curve D. PoissonPlease do not give solution in image format thanku A bank has an average of 10 customers per hour arriving into the system, and it takes an average of 30 minutes for the clerk to complete a transaction with a customer. What is the average length of the queue in the bank? And A store open 24 hours per day is interested in determining store traffic. It found that customers arrive uniformly at the rate of 10 customers per hour. The store has a single worker to process customers. The worker takes an average of 5 minutes to process a customer. If we assume that every customer must be processed, what is the average number of customers in the store?
- In queuing theory and modeling, if 1/μ represents mean service time. Whatdoes μ represent? Service rateInterarrival time Arrival rate NoneWhat effect will decreasing the variability of the service rate have on the performance of the queuing system (all else being the same)? reduce customer average waiting time in the system cannot be determined without additional information while more customers, they arrive at separate times & create a shorter queue the queue moves faster thanks to a faster arrival rateLet a queuing system have the Kendall model (M/M/1) : (GD/infinity/infinity). Assume A < µ. Does W, for the service discipline FIFO equal W, for the service discipline SIRO? O I have no idea. no yes It cannot be determined.
