In logistics management, information systems are part-and-parcel of the business. Some of the information systems used are Logistics Information System (LIS), Warehouse Management System (WMS) and Transportation Management System (TMS). In a recent paper by Mason, Ribera, Farris and Kirk [57], they claimed that “Companies are not suitably equipped to make informed, effective decisions based on the data collected separately by … WMS… and TMS…”, and “Today’s supply chain management systems must not only be able to provide real-time data but also to integrate data across the supply chain and to support real-time decision making in response to changing conditions.” They addressed some of the open questions pertaining to the integration of WMS and TMS, and highlighted the potential benefits of the integration. Also, simulation analysis was used to examine the benefits gained. To benefit the 3PL companies, more research work can be done in this area to address the challenges which are unique being the middle man in the supply chain.
