Abstract

The delivery route for the Bandung 40400 Mail Processing Center is determined based on estimates using a zoning system that can trigger delays. Where each vehicle can only make deliveries to one designated distribution center (DC) in one go. This makes the load factor level of vehicle capacity utilization not optimal, which is still in the range below 20%. This study aims to obtain optimal routes and delivery schedules to improve distribution efficiency and increase the load factor of vehicle capacity utilization. This quantitative research method uses the Saving Matrix algorithm on all distribution routes in the office. The results obtained indicate that the optimal delivery route is to form 5 to 6 clusters where each cluster consists of several service areas. With this shipping route, you can save an average of 8 routes/vehicle, save mileage from 143 to 144 km, and save distribution costs of Rp. 38,798.34 up to Rp. 39,146,50 for one delivery. In addition, there was an increase in the load factor of 18.37% and 16.49% for dropping I and II. Using the proposed route, a resume of the delivery schedule is obtained with clearer departure and arrival times and provides a travel timesaving of 273 to 275 minutes. Expanding the scope of research and comparing the level of effectiveness between distribution centers in various regions can carry out as further research.
