Abstract: Now a days, city courier service is very popular, especially in Indonesia. This popularity is also boosted by the rise of online motorcycle taxi service. By using city courier service, local shipment can be delivered faster rather than regular courier service. One problem in this service is the combined shipping method has not implemented yet. So, for customer who sends more than one package to more than one destination, the cost is still calculated in regular price without any reduction. The other problem is even there is more than one shipment, customer has to create order one by one and the packages will be delivered by different driver. So, developing combined shipping system will benefit the customer and the driver. In this research, we propose combined shipping model for city courier service by comparing two methods: least effort and random walk algorithm. In this study, we compare the performance of combined shipping that uses least effort or random walk method and conventional one to one shipping model. In this research, we found that combined shipping that implements least effort algorithm produces the best performance both in non financial aspect and financial aspect. By using least effort algorithm, system generates lowest total driver travel distance and highest average driver’s travel distance. The financial consequence is lowest total cost that must be paid by customer and highest average driver’s revenue.
