Tabu Search for Vehicle Routing Problems (VRPs)

International Journal of Computer Mathematics, 2002
Vehicle Routing Problems (VRPs) considered in this paper involve a set of engineers operating from one base and a set of geographically distributed jobs or services to be performed by them under the given technological and temporal constraints. All engineers have different time-windows for their working and the technological constraints specify their ...

A comparison between ZOP and VRP techniques: emphasis on possible guided waves in the vrp configuration

2011
Ground penetrating radar (GPR) is a well-established geophysical technique, that has been applied for about two decades. In particular GPR is used, via specific relationships, to estimate hydrological parameters in vadose zone, i.e. moisture content, both from the surface and in boreholes.

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 ...

Predictability of VRP: A Comparison Study

2018
The intertemporal CAPM model of Merton (Econometrica, 41:867–887, 1973) demonstrates that the aggregate market risk is determined by the uncertainty of the underlying return, quantified by the return variance. When holding the market portfolio, however, an investor is also bearing the uncertainty of the variance itself.

Analysing risk orientation in a stochastic VRP

European J. of Industrial Engineering, 2007
In this paper, the value of correctly addressing uncertainty and risk in operational planning is studied in the context of the Vehicle Routing Problem with Stochastic Demands (VRPSD). The main issues analysed in this paper concern (1) the evaluation of different risk attitudes in planning vehicle routes, (2) the value of considering the uncertainty for

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 ...
