MAS infrastructures
To support the development and execution of MASs, tools andsoftware infrastructures are needed.During the years, various tools have been proposed to transformstandard MAS specifications (i.e., AUML specifications) into actualagent code, and a variety of middleware infrastructures have beendeployed to provide proper services supporting the execution ofdistributed MASs.In order to be interoperable, such infrastructures should becompliant with the FIPA abstract architecture.

JADE is one of the most well-known and widely usedFIPA-compliant architectures.Fabio Luigi Bellifemine, Giovanni Caire, Dominic Greenwood.Developing Multi-Agent Systems with JADE. ISBN:978-0-470-05747-6, February 2007, Wiley.The JADE home page: http://jade.tilab.com/

JADE
JADE (Java Agent DEvelopment Framework) is a softwareframework fully implemented in Java language.It simplifies the implementation of MASs through a middlewarethat complies with the FIPA specifications and through a set oftools that supports the debugging and deployment phases.The agent platform can be distributed across machines (which donot even need to share the same OS) and the configuration canbe controlled via a remote GUI.The configuration can be changed at run-time by moving agentsfrom one machine to another one, as and when required.JADE is completely implemented in Java language and theminimal system requirement for running the latest version (version4.5.0 released on 08/06/2017) is JAVA 5.

Beyond Jade
Besides JADE, other agent-based development tools exist, but theyare not commercial projects supported by large and solid companies.This is one of the reasons for the limited adoption of this technology byindustries.
But, what about using existing technologies that are not officiallytagged as “agent-oriented”, but that are very suitable for implementingsoftware agents, for the implementation stage, and a “pure” agentapproach for the modeling and design stages?
