Multimodal processes driven distribution of customers’ ordered services

Le résumé fourni par la source

This paper presents a reference model for the Vehicle Routing Problem with Time Windows and Limited Resources (VRP-TR) imposed by fleet size and vehicle passenger capacity when transporting service teams (STs) to customers at the start of a time window and collecting them at its end. The proposed VRP-TR problem jointly addresses resource feasibility and routing optimization for transporting STs, allowing flexible pickup by different vehicles and prioritizing customer coverage before cost minimization. The adopted model first checked whether the contractor’s limited resources can meet all customer requests within the time horizon, then finds routes minimizing costs. Its hierarchical objective, capacity-driven feasibility, and declarative character enable adaptation to varying operational constraints, yielding solutions and flexibility beyond existing approaches. The model supports both planning service delivery for geographically dispersed customers and designing resource structures for service providers, including home healthcare and maintenance services. Experimental results demonstrate its applicability to real-scale scenarios.
