This vehicle routing problem involves finding a set of trips, one for each vehicle and to pick up known quantities of perishable goods from a set of geographically dispersed suppliers to the cargo terminal of an international airport in south India. The pickup time is based on the deterministic departure time of the flights. The objective of this Vehicle routing problem with Pickup and Delivery...

Vehicle Routing Problem (VRP) is a hot issue in the field of logistics. Furthermore, the Vehicle Routing Problem with Time-Windows (VRPTW) is an additional constraint of the customer access time windows based on the VRP. It becomes a noticeable problem with the development of logistics distribution and the just-intime distribution demand from customers, which increases a visiting window to trad...

Abstract In this paper, we propose a vehicle routing problem with time windows (TWVRP). problem, consider hard constraint that the fleet can only serve customers within specific window. To solve hybrid ant colony (HACO) algorithm is proposed based on and mutation operation. The HACO has three innovations: first to update pheromones new method; second introduction of adaptive parameters; third a...

This paper addresses a new vehicle routing problem that simultaneously involves time windows, split collection and linear weightrelated cost, which is a generalization of the split delivery vehicle routing problem with time windows (SDVRPTW). This problem consists of determining least-cost vehicle routes to serve a set of customers while respecting the restrictions of vehicle capacity and time ...

the heterogeneous fixed fleet open vehicle routing problem (hffovrp) is one of the most significant extension problems of the open vehicle routing problem (ovrp). the hffovrp is the problem of designing collection routes to a number of predefined nodes by a fixed fleet number of vehicles with various capacities and related costs. in this problem, the vehicle doesn’t return to the depot after se...

The multiple vehicle routing problem with time windows (VRPTW) is a hard and extensively studied combinatorial optimization problem. This paper considers a dynamic VRPTW with stochastic customers, where the goal is to maximize the number of serviced customers. It presents a multiple scenario approach (MSA) that continuously generates routing plans for scenarios including known and future reques...

Industrial growth and expanding employment opportunities have led to the urban-oriented economic development in many countries. Demand of transportation, both in terms of passengers as well as for freight is also increasing in and around these big urban conurbations. A high proportion of total goods movement occurs within cities 1) , and most of this movement is based on road transport. Traffic...

In this study, we consider a tactical problem where a time slot combination for delivery service over a given planning horizon must be selected in each zone of a geographical area. Based on the selected time slot combinations, routes are then constructed for the fleet of delivery vehicles for each period of the planning horizon. The routing plan serves as a blueprint for the following operation...
