Abstract

In the implementation of a project, three main aspects are indicators of the success of the project: cost, schedule, and quality. If the cost and time of project implementation are in accordance with the planning and quality requirements, then the project can be said to be successful. Time plays a significant role in construction management projects, where time is also a management function. With good and proper time control, obstacles to delays in project implementation can be avoided as much as possible. The purpose of this study was to determine the cause of the achievement or deviation of work between the realization in the field and the planned time schedule for the procurement of a pedestal crane unit for a new platform in the operational area of ​​ block-B-Natuna.

Abstract

One of the activities in the supply chain system in the motorcycle industry is the process of sending components or spare parts from vendors to motorcycle assembly plants. Delivery of spare parts using the respective vendor's fleet. Along with the increase in market demand, demand for components from vendors has also increased. This has an impact on increasing the number and frequency of fleets entering the factory area; besides that, there is also an increase in transportation costs from Vendors. This study aims to improve efficiency in the number, frequency, and cost of fleet transportation by using the VRP (Vehicle Routing Problem) approach. To get optimal results, the PSO (Particle Swarm Optimization) method was used by utilizing the MATLAB 2020 software. This research involved 40 vendors, logistics partners, and motorcycle assembly factories. The results of this study showed better results, namely, before the research was carried out, the number of fleets was 40 units, and the delivery frequency was 40 times, with a total shipping cost of IDR 2,769,330. Meanwhile, after conducting research using the PSO optimization method, it was obtained that the number of delivery frequency fleets was 8 times with a total shipping cost of IDR 2,679,113.
