ABC Algorithm for VRP

2014
Vehicle routing problem(VRP) has the same mathematical model with many combinatorial optimization problems, they are typical NP- hard problems in combinatorial optimization problem. In this paper, artificial bee colony (ABC) algorithm is applied to solve VRP. We propose a method to keep the colony diversity and improve the search efficiency of ABC.

Complexity of the VRP and SDVRP

Transportation Research Part C: Emerging Technologies, 2011
Abstract In this paper we study the computational complexity of the vehicle routing problem (VRP) and of the split delivery vehicle routing problem (SDVRP) on some special classes of instances, characterized by special structures of the underlying graph, namely a line, a star, a tree and a circle.

The VRP with Time-Window Constraints

2013
In many distribution systems, in addition to the load that has to be delivered to it, each customer specifies a period of time, called a time window, in which this delivery must occur. The objective is to find a set of routes for the vehicles, where each route begins and ends at the depot, that serves a subset of the customers without violating the ...

Cumulative Capacitated VRP optimization

Η παρούσα διπλωματική εργασία εξετάζει το NP-hard Cumulative Capacitated Vehicle Routing Problem (CCVRP), το οποίο αποτελεί επέκταση του κλασικού Vehicle Routing Problem (VRP). Το CCVRP επικεντρώνεται στην ικανοποίηση της ζήτησης των πελατών, ενώ ταυτόχρονα στοχεύει στην ελαχιστοποίηση του χρόνου αναμονής τους, υπό περιορισμούς όπως η χωρητικότητα των ...

Solving VRP Using Ant Colony Optimization Algorithm

2012 Fifth International Conference on Information and Computing Science, 2012
Provides a novel hybrid ant colony algorithm combining genetic algorithm with implicit parallel function to make up the shortcomings of common ant colony alogrithm in the vehicle routing problem including slow convergence in the early stages. Introducing the encoding and mutation operation can improve the efficiency of solving the optimal distribution ...

Predictability of VRP: Hongkong Evidence

2018
Volatility modeling is one of the central issues for theoretical studies and practical applications. In the literature, the conditional volatility model family, i.e. GARCH type model proposed by Engle (1982) (Econometrica 50(4), 987–1007, 1982) and Bollerslev (1986) (J Econom 31, 307–327, 1986) is used to model the fat-tail and the volatility ...
