Software cost estimation

In software engineering, cost estimation defines the calculation of the amount spent on software development and testing. This includes maintenance, managing, buying equipment, user requirement reviews, software, training, and servers. Many methods are developed to estimate the software project cost. Software cost estimation has a major impact on planning and managing a project. The software cost estimation has three estimates like project duration(time), effort(person-month), and cost(dollars).

Let the processes P1, P2, P3, P4, and P5 be given. They arrive in the system at the same time in this order. The processes have the attached service times (in time units) and priorities. For each of the scheduling methods (First Come, first served (FIFO), Shortest Job First, Round Robin, and Priority Scheduling), specify the execution order of the processes and the average execution time (average turnaround time) for all processes. First, determine and state the execution times of the individual processes and then calculate the average value. Note: • For Shortest Job First, If the required service time (CPU time) is the same for two or more processes, use First Come, first served to resolve the conflict. • For Round Robin, the time quantum q = one time unit. • For Priority Scheduling, low integer priority values signify high priorities, with O being the highest possible priority. If multiple processes have the same priority, use First Come, first served to resolve the conflict. Also,…
