Capabilities

What It Does

▸Gantt chart visualization with color-coded process timelines

▸Comparative analysis across all 9 algorithms on the same input

▸Configurable context switch time and time quantum (Round Robin)

▸I/O burst time support for realistic scheduling scenarios

▸Metrics: waiting time, turnaround time, response time, CPU utilization, throughput

▸Published as IEEE paper — applied to vaccine scheduling at AIMV 2021
