Abstract

In the transportation process is closely related to the route, the route is the path through which a mode / vehicle to arrive at a destination. The route is related to the number of vehicles and the location where it goes. PT XYZ is a company engaged in fast moving consumer goods (FMCG), with the field makes the flow of goods speed will be high until the goods distribution process becomes fast and often. In the process of distribution is done by using 1 fleet in each customer. Currently in the process of distributing goods, the company still ignores the utility of the vehicles used, so the availability of empty space in capacity is still occurring and this makes the cost of transportation is high. Consolidation of multiple customers becomes possible, keeping in mind the time window, capacity and multiple products. This study designs a route by considering the limits to get the route, the number of vehicles, the utility increase of each vehicle and the optimal distance so that it can minimize transportation costs. The use of a genetic algorithm preceded by the nearest neighbor algorithm is used to solve this problem. Later the route will be formed and get the number of vehicles, the increase in vehicle utility and the optimal distance. This resulted in average vehicle utility improvement of 35,317%, vehicle repairs amounted to 34.05%, and distance of 10.075% so as to reduce transportation costs by 26.56% from initial conditions. Keywords— Transportation, FMCG, Vehicle Routing Problem, Time Window, Heterogeneous Fleet, Utility, Vehicle Number Determination.

Abstract

To provide internet network, one of public Telecommunication provider in Indonesia conduct several project related to fiber optic cable installation such as the STO Modernization Feeder project. In every project implementation, the company is concerned with quality in order to remain competitive with competitors. Deliverable which meets the project quality will produce the product in accordance with the requirements. STO Garut Feeder Modernization Project was experiencing delays which is caused by the non-conformity project deliverable to project specification during monitoring & controlling phase. At project planning, the quality metric was not designed, which can be used as a guideline for vendor in carrying out the project task and to assist the process of quality control. Quality metric design is carried out using internal control methods that can identify possible errors in each project activity and critical success criteria that define a successful activity that will be performed. Result shows that only 67.1% statement (critical success criteria) form critical activity is implemented. This result can answer why the project delay because the activity on critical path is mostly re-worked due to non-conformity issues. Keywords—Quality, quality metric, internal control, control quality, telecommunication project
