A queueing system has 1 server and two phases. The interarrival time is uniform between 20 and 50 seconds. The service times of the first phase is exponential with an average of 75 seconds, and the second phase exponential with an average of 90 seconds. Use a simulation run length of 1,000 arrivals. Explain what is the point estimate for the total number of customers and the time they will spend in the system?

You are developing a simulation model of a service system and are trying to create an input model of the customer arrival Process, You have the following four observations of the process of interest [86, 24,9, 50] and you are considering either an exponential distribution Of a uniform distribution for the model. Using the data to estimate any necessary distribution Parameters, write the steps to plot Q-Q plots for both cases i.e. exponential and uniform.

1. Suppose you are developing the simulation model of a communication system where the incoming calls are being served by a single service person. Assume the arrival of the calls as well as their service times are random. Identify some entities, attributes, activities, events and states variables for this simulation mode b. Is very necessary to carryout an output analysis of simulation model. Why? Are the output data from simulation normally distributed? Discuss your answer with example
The structure of the FSM can also be interpreted as a model fora specific walking pattern in a square grid. Supplement it by introducing suitablefrequency counters so that it can be used for predicting the player’s movements.What kind of a software client interface should the FSM have? How can it be usedfor producing randomized square grid walks with respect to the model?

Considering the pseudo-code of the wait() and the signal() system calls with NO Busy waiting: a) Make your own UNIQUE and ORIGINAL simulation where 4 processes (Pi, P?, P?? and P???)1 want to enter the same critical section: at every row of the simulation show ALL interesting parameters, e.g. S.value, S.L, and make appropriate comments. The simulation must stores at least 8 rows. b) Assuming that, at time t, the process control block of Pi is in the queue of S.L: 1) Which is the current state of Pi? 2) Does Pi have a partition in Main Memory (MM)? Explain (no point without explanation).
The language must be in python. Neural Network Units weights of [-1.2, -1.1, 3.3, -2.1] two training examples:Example 1: [0.9, 10.0, 3.1, 1]Example 2: [0.9, 2.1, 3.7, 1] Note that you don't have to explicitly include a threshold or bias since the examples include a last element of 1 which means that the last weight effectively operates as a threshold. Create a single ReLU unit and provide the outputs for those examples. Calculate the derivative of the sigmoid with respect to net input for both examples Calculate the derivative of the ReLU with respect to net input for both examples
Write a program to generate the desired output for the model. Use it to estimate the average time that a customer spends in the system and the average amount of overtime put in by the server, in the case where the arrival process is a Poisson process with rate 10, the service time density is g(x) = 20e^−40x (40x)^2, x > 0 and T = 9. First try 100 runs and then 1000.
