1 Problem : Interarrival Time and Service Time in a simulation study for a bank system are shown in the following table: Interarrival Time (min) 2 1 6 3 6 4 2 4 1 Service Time (min) 4 3 4 5 1 5 3 2 4 If the simulation runs for 1 hour, build the simulation table and the scheduling table for first 20mins. You need to perform, FEL, Service Time, Idle/Busy Status, Queue Length, and so on.

a) Complete the simulation table accordingly. b) Assume a M/M/1 queue configuration, define the following:i). The average time a voter spends waiting to vote. c) Definei). A reasonable voter arrival rate.

Suppose there are five processes, their arrival time and running time are listed as follows. Adopt FCFS and SJF, respectively, give the schedule order and average waiting time. Give the schedule order of SJF.  Compute the average waiting time of SJF.  Process Arrival time Running time P1 P2 P3 P4 0 3 4 5 3 10 6 1

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).

Draw a model in BPMN that can produce every possible execution sequence that includes tasks {p, q, r,s, t}. Discuss the fitness and precision of this model with respect to the workflow log {<p, q, r, s, t>,<p, r, q, s, t>}. Draw a process model that would have perfect fitness and perfect precision with respectto this workflow log. Would the alpha-Algorithm produce this model with perfect fitness and precision? (Business 2710 - Modeling and Implementing Business Processes question.)

Consider the following processes:Process Arrival Time Service Time A 0 4 B 1 3 C 2 3 D 2 2 E 3 1 F 5 3 Show (draw the schedule, x-axis is time, and one row for each CPU) how the aboveprocesses execute over time on a system with 2 CPUs. Compute the average turnaroundtime for all processes and the average utilization for each CPU under each of the following schedulers: (a) FCFS with a single Ready Queue. A process gets scheduled once one of the CPUsis available. When both CPUs are available, we select CPU1. (b) FCFS with a Ready Queue per CPU. Processes A, B, and C go to CPU1 and processesD, E, and F go to CPU2. (c) HRRN with a single Ready Queue. A process gets scheduled once one of the CPUsis available. When both CPUs are available, we select CPU1.

In question b, the difference between processing delay and queue time is discussed in full. Think about the following example:

For the interactive system in Figure, suppose that we are given the following information:mean user think time = 5 secondsexpected service time at device i = 0.01 secondsutilization of device i = 0.3utilization of CPU =0 .5expected number of visits to device i per visit to CPU = 10.expected number of jobs in the central subsystem (the cloud shape) = 20.expected total time in system (including think time) per job = 50 seconds.How many jobs are there in the queue portion of the CPU on average. E[NQcpu]??

A service has five tasks, performed in sequence.  In the instance when there is more than one worker assigned to a task, each worker performs the entire task and they both can be working on different “items” at the same time. What is the throughput time (assuming no wait time)? Please provide details as to how this is calculated.    Task Task time per worker Number of workers 1 2 minutes 1 2 6 minutes 1 3 14 minutes 2 4 4 minutes 1 5 15   minutes 3

Suppose the manufacturing and assembling of an object goes through the following different stages. By using the following assembly lines, you have to calculate the shortest path and minimum time required to manufacture the whole object. Draw the proper number of tables and highlight the shortest path also.
