A Simheuristic for the Stochastic Two-Echelon Capacitated Vehicle Routing Problem
2020 Winter Simulation Conference (WSC), 2020Two-echelon distribution systems are very common in last-mile supply chains and urban logistics systems. The problem consists of delivering goods from one depot to a set of satellites usually located outside urban areas and from there to a set of geographically dispersed customers.

Sustainable urban freight transport: A simheuristic approach
2017 Winter Simulation Conference (WSC), 2017In modern society, sustainable transportation practices in smart cities are becoming increasingly important for both companies and citizens. This paper addresses a rich extension of the capacitated vehicle routing problem, which considers sustainability indicators and stochastic traveling times.

2020 Winter Simulation Conference (WSC), 2020
In this paper, we consider the stochastic team orienteering problem with dynamic rewards (STOPDR) and stochastic travel times. In the STOPDR, the goal is to generate routes for a fixed set of vehicles such that the sum of the rewards collected is maximized while ensuring that nodes are visited before a fixed time limit expires.

A Simheuristic for the Heterogeneous Site-Dependent Asymmetric VRP with Stochastic Demands
2016Rich Vehicle Routing Problems (RVRPs) refer to complex and realistic extensions of the classical Vehicle Routing Problem. They constitute a hot topic in logistics due to their high number of relevant applications. This work focuses on a RVRP with the following characteristics: (a) heterogeneous fleet of vehicles, (b) site-dependency, i.e., not all ...

Smart Simheuristic Approach for Stochastic Single-Machine Scheduling
Scheduling decisions in Industry 4.0 environments are increasingly exposed to uncertainty arising from dynamic shop-floor conditions, making deterministic plans prone to performance loss during execution. This study focuses on a stochastic single-machine scheduling problem with sequence-dependent setup times and proposes a smart simheuristic that ...Beyza Gunesen Akansu, Muzaffer Kapanoglu
