Optimizing the Strategic Decisions for One-Way Station-Based Carsharing Systems: A Mean-CVaR Approach

open access: yesIEEE Access, 2021
The study focuses on the strategic decisions including on the location and capacity of stations and the fleet size for designing the one-way station-based carsharing systems. Under demand uncertainty, we introduce a two-stage risk-averse stochastic model

A branch‐and‐cut algorithm for partition coloring [PDF]

open access: yesNetworks, 2009
AbstractLet G = (V, E, Q) be a undirected graph, where V is the set of vertices, E is the set of edges, and Q = {Q1,…,Qq} is a partition of V into q subsets. We refer to Q1,…,Qq as the components of the partition. The partition coloring problem (PCP) consists of finding a subset V′ of V with exactly one vertex from each component Q1,…,Qq and such that ...

Multi-Objective Trip Planning With Solution Ranking Based on User Preference and Restaurant Selection

open access: yesIEEE Access, 2022
The tourist trip design problem (TTDP) helps the trip planners, such as tourists, tour companies, and government agencies, automate their trip planning. TTDP solver chooses and sequences an optimal subset of point of interest (POIs), which adhere to the ...

A Branch-and-Cut Algorithm for Submodular Interdiction Games

open access: yesINFORMS Journal on Computing, 2022
Many relevant applications from diverse areas such as marketing, wildlife conservation, and defending critical infrastructure can be modeled as interdiction games. In this work, we introduce interdiction games whose objective is a monotone and submodular set function.

Separating valid odd-cycle and odd-set inequalities for the multiple depot vehicle scheduling problem

open access: yesEURO Journal on Computational Optimization, 2013
We consider the multicommodity network flow formulation of the multiple depot vehicle scheduling problem (MDVSP) and investigate several strategies within a branch-and-cut framework for solving the MDVSP.
