Variable Neighbourhood Decent for Parking Allocation Problem
Résumé
Searching for available parking lots presents a mayor problem in urban areas.
Massive unorganized pursuit for parking provokes traffic congestion, financial losses, negative
environmental effects, among others. Most studies on this topic base their research on simulations due to the large set of non-deterministic input. In this paper we propose an approach
where each vehicle that is looking for a parking lot is equipped with GPS device. Based on this
assumption, the static Parking allocation problem (PAP) can be modeled as a variant of Generalized assignment problem (GAP). Here we also discuss inclusion of the static model into a
dynamic real-world circumstances. Moreover, we developed a heuristic based on sequential Variable Neighborhood Decent (VND) to solve static PAP. It uses two neighborhood structures :
reallocation and interchange. It appears that the deviation of VND based heuristic, compared
with the optimal solutions, are always less than 0.1%.
