A comparison of trajectory granular based algorithms for the location-routing problem with heterogeneous fleet (LRPH)
(Universidad Nacional de Colombia, 2017)
We consider the Location-Routing Problem with Heterogeneous Fleet (LRPH) in which the goal is to determine the depots to be opened, the customers to be assigned to each open depot, and the corresponding routes fulfilling ...
Efficient heuristic algorithms for location of charging stations in electric vehicle routing problems
(National Institute for R and D in Informatics, 2018)
Eco-responsible transportation contributes at making a difference for companies devoted to product delivery operations. Two specific problems related to operations are the location of charging stations and the routing of ...
A flexible mathematical model for the planning and designing of a sporting fixture by considering the assignment of referees
(Growing Science, 2019-04)
This paper deals with the problems faced with the designing and planning of a sporting fixture considering correct referee assignments. A non-linear binary program model is proposed to solve the problems, which aims to ...
Simplified mathematical model for computing draining operations in pipelines of undulating profiles with vacuum air valves
(MDPI AG, 2020-09)
The draining operation involves the presence of entrapped air pockets, which are expanded during the phenomenon occurrence generating drops of sub-atmospheric pressure pulses. Vacuum air valves should inject enough air to ...
Multimodal Capacitated Hub Location Problems with Multi-Commodities: An Application in Freight Transport
(Hindawi Limited, 2020)
Hub location problems (HLPs) support decision making on multimodal transport strategic planning. It is related to the location of hubs and the allocation of origin/destination (O/D) flow in a system. Classical formulations ...
A practical methodology of design of off-line reservoirs for reducing maximum water levels in urban channels
(Elsevier B.V., 2020-08)
Flooding can often occur in many places due to the increasing trend of rainfall events (climate change), the urbanization process of a catchment area, or by an undersized urban channel. Reservoirs are used for limiting ...
