The Vehicle Routing Applications Modelling Tool (VAMT) is a software system which: models a specific transportation management application, typically, a decision support system for optimized transportation management; automatically configures and generates a bespoke software application based on the defined application model. VAMT eliminates the software bottleneck in the development and modification of bespoke, versatile, effective, and efficient software decision support tools in the area of transportation logistics management. The VAMT target applications cover a wide variety of business areas. Application types may vary from simulators for optimized transportation network configuration at the strategic and tactical planning levels, to decision-support systems for dynamic dispatching of a fleet of vehicles at the operational level. Common denominators are decision support, and optimization. The VAMT user has large flexibility in selecting the appropriate optimization criteria, constraint types, and business rules for a given target application. The automated application generation includes the development of graphical user interfaces, as well as interfaces to geographical information systems (GIS) and legacy systems. The VAMT needs a Vehicle Routing Problem solver such as Dispatcher 1.1 from ILOG. The modelling process and the subsequent automatic system installation VAMT will typically take only a few hours and does not require IT proficiency. Hence, the software bottleneck will be eliminated, both for system development and modification. The VAMT product is targeted at the following market segments developers of software solutions for optimised transportation logistics; software vendors of solutions for optimised transportation logistics; end users of software systems for transportation management; transportation service users (eg manufacturing companies); transportation service providers; transportation logistics management services providers.
ILOG Dispatcher is a software component that elaborates vehicle routing and technician dispatching plans, known in the trade as vehicle routing problems (VRP). Dispatching staff is assisted in planning service rounds at the lowest cost possible while accommodating business constraints such as customer orders, visit time windows, driver timetables, work-hour regulations, fleet capacity and other characteristics. Efficient vehicle routing has tangible direct and indirect effects: lower costs as fleet use is streamlined; superior quality in customer service due to precise routing plans and immediate reactivity; higher motivation due to less driving time, rationalised routing and driver workloads, personalized working hours, reduced driver fatigue and frustration; less environmental impact and lower density of utilitarian traffic as fewer vehicles are on the road and for shorter periods of time. Major innovations of ILOG Dispatcher are performance, quality and flexibility: the solving engine is world-class, outperforming analogous products on several standard benchmarks; feasible plans are produced that maximize the number of satisfied goals; in the face of evolving situations dynamic rescheduling is immediate, permitting on-the-fly re-application or modification of user-defined strategies, priorities and ordering. Underlying technology is a unique blend of constraint satisfaction and operations research optimization technology. Elaborated as a C++ class library, ILOG Dispatcher is fully-portable (UNIX, Windows 95 and NT), and can easily be integrated into existing information systems and used with any database, geographic information system and management application. New business requirements are taken into account with minimal reconfiguration. ILOG Dispatcher is already being used or is planned for use in package delivery services, intra-enterprise supply chain management, and maintenance technician dispatching.
