the goal of this paper is to develop a decision support system (dss) as a journey planner in complex and large multimodal urban network called rahyar. rahyar attempts to identify the most desirable itinerary among all feasible alternatives. the desirability of an itinerary is measured by a disutility function, which is defined as a weighted sum of some criteria. the weights represent travelers’...
• New OP variant with service time dependent profits and travel times. Mathematical formulation possible applications of this problem. Metaheuristic solution approach composed specific local moves. Benchmark instances known optimal solutions to verify the approach. Real data instance evaluate proposed model method. This paper addresses orienteering problem windows (TDOPTW-STP). In TDOPTW-STP, e...
The travel times among demand points are strongly influenced by traffic in a supply chain. Due to this fact, the service times for customers are variable. For this reason, service time is often changes over a time interval in a real environment. In this paper, a time-dependent periodic green vehicle routing problem (VRP) considering the time windows for serving the customers and multiple trip i...
In order to improve service quality and satisfy specific delivery requests from different customers, suppliers are tending to afford more efficient and convenient distribution services rather traditional approaches. For example, customers may change preferred hours of receiving their orders, and due to this, wholesalers must distribute goods in different time windows. In this article, for the f...
