CPU Scheduling Simulator – Multi-Algorithm Analysis Tool

Developed a desktop-based CPU Scheduling Simulator to implement, analyze, and compare multiple scheduling algorithms used in Operating Systems.

Technologies Used:

C# – .NET Framework – Windows Forms

The simulator implements:

FCFS

Shortest Job First (Preemptive & Non-Preemptive)

Priority (Preemptive & Non-Preemptive)

Round Robin

Key Features:

Input process ID, arrival time, and burst time

Toggle between preemptive and non-preemptive modes

Automatic calculation of:

Waiting Time

Turnaround Time

Average Waiting Time

Average Turnaround Time

Gantt Chart visualization of process execution

Pie chart for CPU distribution

Histogram comparing average waiting time across algorithms

Automatic detection of the best-performing algorithm

Import and export functionality for process data

I was responsible for:

Implementing scheduling algorithms from scratch

Handling process state transitions and timing calculations

Designing the UI using Windows Forms

Developing data structures for accurate simulation

Building visualization components for performance comparison

This project strengthened my understanding of Operating Systems concepts, algorithm efficiency, time complexity, and performance analysis through practical implementation.
