| Abstract: | Technological advances such as global positioning, telematics, RFID, wireless communication, etc. allow to improve near real-time visibility over assets in transit. Despite the technological advances it appears that many global supply chains still suffer from the lack of visibility. While the costs for deploying systems providing visibility can be determined relatively easy, there is only little knowledge about the business value that can be generated with near real-time information on assets in transit. Obviously, the availability of data is not a value by itself and real-time data on assets in transit must be converted into information that can be used to generate business value. This joint research by Deutsche Post World Net, DHL Exel Supply Chain, MIT Center for Transport & Logistics, and the Zaragoza Logistics Center, seeks to assess the value that can be generated with In-Transit Visibility. It begins with describing the concept of In-Transit Visibility and briefly surveys related work, existing visibility systems, and best practices. Achieving In-Transit Visibility in many international supply chains faces various challenges: a) assets in transit may be consolidated and deconsolidated in the supply chain b) various stakeholders in the transportation chain have different interests, business rules, process definitions, and data requirements c) capabilities to react on disruptions in the supply chain differ between the various actors involved and actors in the transportation chain usually do not have exact knowledge about the capabilities of other actors. These challenges make it difficult to identify disruptions and to appreciate their impact on the final customer. This research shows how In-Transit Visibility can be achieved and illustrates the fundamental differences between Tracking & Tracing and In-Transit Visibility. A framework for assessing the value of In-Transit Visibility is developed in this research. This framework links visibility capabilities to actions and values and shows which visibility-enabled actions can generate which values with respect to the specific supply chain characteristics. This mapping of supply chain characteristics, actions, values, and visibility information is illustrated in case studies. Simulation tools are developed in order to quantify the value that can be generated with In-Transit Visibility. These simulation tools are described and the results of our computational experiments are presented in this report. Our experiments clearly show that In-Transit Visibility can significantly improve on-time delivery performance, reduce transportation costs, and improve supply chain performance. |
