Time and Cost Optimization in Feasibility Test of CCTV Project using CPM and PERT

Abstract

Completing a closed-circuit television (CCTV) project on time and within budget is not an easy thing. Scheduling and planning in the CCTV project hold an essential role in predicting the aspects of time and project costs. The success or failure of a project can be viewed on the initial process of CCTV planning, including projecting the crash because of the absence of optimization in terms of plan which led to the in the effectively of the project. This research aims to find the trade-off between cost and optimal time required to complete the project of CCTV by using Critical Path Method (CPM) and Project Evaluation and Review Technique (PERT). CPM and PERT are used to make working time and cost of the project more effective and efficient. The evaluation of this research uses data about the project time and expenses from computer vision (CV) Aditya IT Consultant, a software house based in Kediri, East Java. The expected duration is 73 days, and the normal cost is IDR 207,858,300. However, by using CPM and PERT, the optimal time is 48 days with the price IDR 168,608,300. The conclusion is CPM and PERT make the working time and cost of a project effective and efficient by reducing the completion time and cost up to 25 days and IDR 39,250,000.
