A FUZZY APPROACH TO THE VEHICLE ASSIGNMENT PROBLEM.

Transportation companies receive a great number of requests every day from clients wanting to send goods to different destinations. Their fleets often consist of several different types of vehicles. Dispatchers assign vehicles to transportation requests relying primarily on their experience and intuition. When assigning a certain type of vehicle to a transportation request, the dispatcher must bear in mind a large number of different factors. This paper considers the vehicle assignment problem when vehicle dispatching is done “today for tomorrow”. The paper develops a model based on fuzzy logic that assigns different types of vehicles to planned transportation tasks. The model is tested on a real numerical example. The results of testing the model indicate that it outperforms the work of an experienced dispatcher.

Gender differences in travel behaviour and willingness to adopt sustainable behaviour

ABSTRACT This paper presents pioneering research on gender differences in travel behaviour in southeastern Europe. The study analyses the socio-economic and main travel characteristics (particularly parking) of men and women. Additionally, it examines the influence of parking demand management measures on their behaviour, in terms of the willingness of men and women to reduce car use and to adopt more sustainable behaviour. The results reveal significant differences between genders in most of the characteristics examined. Moreover, it is shown that women are less car dependent and more sensitive to parking pricing and, therefore, more willing to replace a car journey with public transport. These findings suggest that gender should be an essential parameter when user behaviour is examined and modelled. Furthermore, the results indicate that gender differences must be considered when transport policy is created to affect the behaviour of men and women equally. The achievement of social equality is one of the primary objectives of sustainable development.
