讲座题目：Dynamic Truckload Hyperpath Model: The Engine for Smart On-Line Freight Logistics
主讲人：聂宇 教授（Yu (Marco) Nie） 美国西北大学
The trucking industry, the backbone of freight transportation in many parts of the world, is highly fragmented. Operating in such an intensely competitive market is challenging, especially for the small carriers who have neither much bargain power nor viable means for consolidation or collaboration. The key to survive thus lies in the ability to discover high-value loads as quickly as possible and the flexibility to follow them wherever they arise. Compared to big players, however, small carriers are also at disadvantage when it comes to accessing load information across the entire network. Not surprisingly, when left to their own devices, these carriers often fail to match their assets to most profitable loads in time, which not only hurts their profitability but also drags down the efficiency of the entire industry.
One of the promising solutions to breaking this information barrier, enabled by mobile computing and communication technologies, is the online freight exchange (OFEX) system, which provides a platform that allows shippers to advertise loads publicly or privately to a large number of freight operators that are looking for loads. The fundamental question for an OFEX platform is how to guide the carriers, who do not usually have a contractual relationship with the platform, to haul most suitable loads, by leveraging on the platform's visibility of network-wide demand and supply information. This question is at the core of OFEX's value-added services, and also the focus of the talk.
In this talk I will describe a novel problem of guiding trucks to match with the most suitable loads in order to maximize expected profit in a shipping tour. Leveraging on OFEX's visibility of network-wide demand and supply information, the underlying optimization problem prescribes a hyperpath-based, joint routing and bidding strategy in an intercity truckload shipping context. The problem has several distinctive features: complete decentralization of decision-making, integration of bidding and routing, and representation of adaptive decision as hyperpath. I will also discuss how this problem may be extended and integrated into the OFEX’s cover business operations.
