A multi-scale agent-based modelling framework for urban freight distribution

Modelo de simulação baseada em agentes para avaliar política de distribuição de cargas urbanas do e-commerce

“…Isso se deve ao fato de a MSBA utilizar em sua construção os objetivos e comportamentos individuais dos agentes (Elbert e Friedrich, 2018;Firdausiyah et al, 2019). Alguns estudos tem obtido tal feito ao utilizar este tipo de simulação em logıśtica urbana (Alho et al, 2017;Roorda et al, 2010;Teo et al, 2012). Nestes trabalhos, os stakeholders envolvidos na logıśtica urbana são modelados como agentes capazes de tomar de-cisões e interagir entre si e com o meio, ao se deparar com uma situação pré-determinada (Davidsson et al, 2005).…”

“…A maior parte dos trabalhos que utiliza MAS como um sistema de decisão multi-agente e lidam com polıticas que buscam de alguma forma restringir a circulação de veıćulos (Alho et al, 2017;Davidsson et al, 2005;Roorda et al, 2010) ou estudam algum caso especi9ico (Elbert e Friedrich, 2018;Firdausiyah et al, 2019;van Heeswijk et al, 2019). Nenhum desses trabalhos analisa os impactos da aplicação das EEAs no ambiente urbano por meio de MSBA, que é o foco desse trabalho.…”

Commodity flow estimation for a metropolitan scale freight modeling system: supplier selection considering distribution channel using an error component logit mixture model

“…The connections between the receivers and suppliers established by the model are to be used for generating shipments. A carrier operation model, which is included in Sim-Mobility (Alho et al 2017) (and, also, in other disaggregate urban freight simulators), takes these shipments as inputs and generates goods vehicle tours and trips, which are, in turn, the inputs for a traffic simulation. The type of the distribution channel can be considered at each of the steps that follows the commodity flow estimation.…”

“…Several urban freight modeling systems have been proposed in the literature (e.g. Boerkamps et al 2000;Fischer et al 2005;Wisetjindawat et al 2005Wisetjindawat et al , 2006Hunt and Stefan 2007;Nuzzolo and Comi 2014;Moeckel and Donnelly 2016;Alho et al 2017) and, overall, freight modeling has been advanced significantly during the last few decades. However, the models for the commodity flows within a metropolitan area are underdeveloped (Comi et al 2012).…”

“…business characteristics and overnight parking locations for goods vehicles, to those relevant to daily logistics operations, e.g. vehicle touring, route choice, and delivery/pick-up parking (Alho et al 2017). The proposed approach is also applicable to the commodity flow estimation in other existing urban freight modeling systems.…”
