In the context of increasing demands for home delivery fresh food, this article addresses terminal distribution problem in an urban environment, which is called vehicle routing probl...

Vehicle Routing Problem is a well-known problem in logistics and transportation, and the variety of such problems is explained by the fact that it occurs in many real-life situations. It is an NP-hard combinatorial optimization problem and finding an exact optimal solution is practically impossible. In this work, SiteDependent Truck and Trailer Routing Problem with hard and soft Time Windows an...

We present a modification of the vehicle routing problem with the additional restriction that time windows are associated with each customer by defining an interval wherein the customer has to be supplied. We introduce a two phase strategy of this vehicle routing and scheduling problem with time windows using fuzzy logic to realize inference steps in fuzzy if-then rule bases.

Most time-dependent vehicle routing problems are based on a similar modeling paradigm: travel time information is represented by functions between pairs of points interest (e.g., depot or customers). Only few papers investigate how these can be computed using the available information. Furthermore, most them neglect possibility that different paths could selected in road network depending compr...

customer service level is of prime importance in today competitive world and has various dimensions with delivery quality being one of the most important ones. delivery quality has several parameters such as deliver time window options, time window size, etc. in this paper we focus on one of these parameters, namely time window setting. it has a direct impact upon customer satisfaction and busi...
