Analisis Penjadwalan Ulang Proyek Pembangunan Jembatan Savanna Sumatera dengan Menggunakan Metode Pert & Simulasi Monte Carlo

Abstract

In general, project schedules are typically created manually, which can lead to delays during implementation in the field. This is because uncertainties are not included in planning the project schedule. Delays in completing one task will result in the postponement of the next task. This research aims to reschedule to minimize delays in implementing the Savanna Sumatra Bridge Construction Project. This research uses the PERT Method & Monte Carlo Simulation in rescheduling, which involves using 3 time assumptions for each project work item: optimistic duration, most likely duration, and pessimistic duration. The research results using the PERT method obtained a project completion schedule of 162 working days with a 99.9% probability of project completion, 34 days faster than the project target duration of 196 working days. In the Monte Carlo Simulation with 3000 iterations using Oracle Crystal Ball software, the Mean project completion duration obtained was 162.77 days with a 50% probability and a Mean Std.Error of 0.11. To achieve a 99.9% probability in the Monte Carlo simulation with 3000 iterations, the project completion duration is 184 days, which is longer compared to the duration using the PERT method, which is greater than the duration using the PERT method, but still faster than the schedule plan of 196 days.
