Optimizing Project Duration and Cost of Support Ship through Time-Cost Trade-Off Analysis and Microsoft Project Application: A Case Study at PT XYZ
Abstract
The construction of a ship project requires time control to avoid delays because late fines will be imposed. This control can be carried out using project management control tools, namely project scheduling. This research aims to optimize project duration and costs by finding the critical path using the help of Microsoft Project Software and accelerating to avoid project delays using the time cost trade off method. The data collection method was carried out by interviews and direct observation at the project location and obtained through PT XYZ internal parties. The research results showed that there was a delay of 12 days on the Support Ship construction project with 10 critical activities on the production floor. Alternative acceleration is done by adding working hours (overtime) by 2 hours, 3 hours and 4 hours. After calculating the acceleration for critical activities that have the lowest cost slope values, The optimal duration and costs were obtained by adding 3 hours of overtime so that the processing time could be accelerated from 236 days to 228 days with a total acceleration cost of IDR 53,295,000.
