Vehicle routing solutions delivered to companies as packaged applications combine vehicle routing decision-making models and supporting services for data integration, presentation and other functionality. The packaged applications often are tailored to specific needs of their users thought customization methods and mainly focus on the supporting services rather than on modification of the routing models. This paper proposes a method for customization of the routing model as a part of the routing application. The customization method enables companies to incorporate their specific decision-making goals and context into the routing model without redesigning the model itself. The routing model is also capable of adapting its behaviour according to observed interdependences among decision-making goals and routing context. An illustrative example is provided to demonstrate customization of the routing solution and to highlight multi-objective and context-dependent characteristics of the vehicle routing problem
