Multi entity perspective freight demand modeling technique: Varying objectives and outcomes

Agent and Multi-Entity Systems Modeling

This paper describes a method for studying the functional and temporal performance of systems controlled by distributed autonomous agents through simulation of the agents within larger systems. There are many challenges to developing successful agent systems. Although there are multiple agent architectures or approaches for a given application, it is difficult to predict which is best. The beha...

Understand and Calibrate Urban Freight Demand

Increases in population and economic growth in urban areas have led to a growing demand for goods and services by commercial and domestic users. This paper reviewed the analytical architecture of urban freight demand (UFD), and summarized two approaches to collecting and calibrating UFD, namely from macro and micro level. With time-access regulations and vehicle restrictions are increasingly us...

Entity Relationship modeling from an ORM perspective: Part 2

This article is the second in a series of articles dealing with Entity Relationship (ER) modeling from the perspective of Object Role Modeling (ORM). Part 1 provided a brief overview of the ER approach, and then covered the basics of the Barker ER notation [1], that has long been supported in CASE tools from vendors such as Oracle Corporation. In this notation, entity types are depicted as name...

Multi Entity Perspective Transportation Infrastructure Investment Decision Making

Investment in new large transportation infrastructure is capital-intensive and irreversible in nature. Private sector participation in infrastructure investment has gained popularity in recent times because of scarcity of resources at the public sector, and because of the ability of the private sector to build, operate, maintain such facilities, and share future uncertainties.
