MADSYS system will be used in the interface agent （agents） of multi-agent investment management information system. One of the principal tasks of the multi-agent system is to help an investor to make investment decisions and to provide appropriate investment proposals according to the investor＇s profile. From MADSYS depends a lot of things, namely the multi-agent investment management information system accuracy, proposed investment decisions, the right portfolio allocation of financial assets, reliability and investor satisfaction. The usage of MADSYS system in the multi-agent system makes it more intellectual, i.e. the system will be able to adjust automatically to the changing of investor profile.

According to this perspective, the financial earnings resulting from the implementation of transport infrastructure can be captured for its own investment. Given the restrictions of society indebtedness, due to social inequalities, scarcity of resources and insufficient fare collection, with the current financial model for public transport infrastructures, the value capture configures as a strategy to be explored to obtain resources. This paper presents the concept of value capture and its connection and relevance with transport infrastructure financing strategies. Applied to the evaluation of the impacts on the surrounding regions of one of the most significant Brazilian transport projects, the improvement and expansion of Belo Horizonte＇s metro, the provided value capture outcomes open more realistic perspectives for greater engagement of the Public Sector in such projects.展开更多

文摘A transport infrastructure is not only a trip provision system but a public facility that generates value for companies and for the society through expanding markets or developing cities, creating another perspective for new investments, as well as its own financing. According to this perspective, the financial earnings resulting from the implementation of transport infrastructure can be captured for its own investment. Given the restrictions of society indebtedness, due to social inequalities, scarcity of resources and insufficient fare collection, with the current financial model for public transport infrastructures, the value capture configures as a strategy to be explored to obtain resources. This paper presents the concept of value capture and its connection and relevance with transport infrastructure financing strategies. Applied to the evaluation of the impacts on the surrounding regions of one of the most significant Brazilian transport projects, the improvement and expansion of Belo Horizonte＇s metro, the provided value capture outcomes open more realistic perspectives for greater engagement of the Public Sector in such projects.
