City logistics for mega city: A conceptual model (Case study: DKI Jakarta)

As one of the mega cities in the world, to meet the needs of its population, DKI Jakarta not only faces logistics problem which is low availability, but also transportation problem which is traffic congestion. Those problems show that DKI Jakarta needs an urban logistics system that is not only effective and efficient, but also that does not add its transportation problem. Urban logistics system that takes into account traffic congestion is known as city logistics. Therefore, to address these needs, city logistics needs to be developed in DKI Jakarta. The importance of considering traffic congestion in developing urban logistics systems is due to traffic conditions that are getting worse lately in many cities in the world. This research is trying to develop city logistics that is able to solve low availability and traffic congestion problems as well. City logistics that is able to solve the problems has never been developed before. To develop city logistics for the problems, it needs to determine city logistics system, fundamental concept of city logistics, and initiatives of city logistics that are able to solve the problems.

Single-tier city logistics model for single product

This research develops single-tier city logistics model which consists of suppliers, UCCs, and retailers. The problem that will be answered in this research is how to determine the location of UCCs, to allocate retailers to opened UCCs, to assign suppliers to opened UCCs, to control inventory in the three entities involved, and to determine the route of the vehicles from opened UCCs to retailers. This model has never been developed before. All the decisions will be simultaneously optimized. Characteristic of the demand is probabilistic following a normal distribution, and the number of product is single.
