To increase the assurance with which agents can be deployed in operational settings, we have been developing the KAoS policy and domain services. In conjunction with Nomads strong mobility and safe execution features, KAoS services and tools allow for the specification, management, conflict resolution, and enforcement of DAML-based policies within the(More)

SUMMARY Many organizations spend a lot of time and effort analyzing the knowledge people within the organization use to perform their work. This is often done to make the work process more efficient, or to manage the knowledge resources (man, machine, or other) better. To do this, the first thing that is often done is to model the current state of the work(More)
In this paper, we describe the Compendium methodology and suite of tools. Compendium is the result of over a decade's research and development at the intersection of collaborative modeling, organizational memory, computer-supported argumentation and meeting facilitation. We claim that Compendium offers innovative strategies for tackling several of the key(More)
W ork systems involve people engaging in activities over time—not just with each other, but also with machines, tools, documents, and other artifacts. 1 These activities often produce goods, services, or—as is the case in the work system described in this article—scientific data. Work systems and work practice evolve slowly over time. The integration and(More)
We identify four methodologies that need to be present for modeling and simulation in a collaborative analysis or design project. The first of the four, methodology M1, refers to how participants perceive their problem situation and create static, or descriptive models. This paper describes the requirements for a successful methodology M1. It then describes(More)
A continuing problem in business today is the design of human-computer systems that respect how work actually gets done. The overarching context of work consists of activities, which people conceive as ways of organizing their daily life and especially their interactions with each other. Activities include reading mail, going to workshops, meeting with(More)
We have developed a model-based, distributed architecture that integrates diverse components in a system designed for lunar and planetary surface operations: an astronaut's space suit, cameras, all-terrain vehicles, robotic assistant, crew in a local habitat, and mission support team. Software processes (" agents ") implemented in the Brahms language, run(More)
