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)
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)
This paper outlines the technical and social dimensions to a hypertext tool that has been successfully used in organizational settings to improve meetings, and capture group memory in real time. The approach derives from hypertext research systems from the mid-1980s-90s which sought to manipulate conceptual structures as hypertextual concept maps. However,(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)
In this paper we report results of an informal field study of a software development team conducted during an eight week internship at the NASA/Ames Research Center. The team develops a suite of tools called MVP, and is composed of 31 co-located software engineers, who design , test, document, and maintain the different MVP tools. We describe the formal and(More)
that they will function less like tools and more like teammates. 1–3 Many approaches to designing more team-like cooperation between humans and machines have been proposed, including function allocation, supervisory control, adaptive automation, dynamic task allocation, adjustable autonomy, mixed-initiative interaction—most recently regrouped under the(More)
– In this paper, we outline an approach to policy-based coordination in joint human-agent activity. The approach is grounded in a theory of joint activity originally developed in the context of discourse, and now applied to the broader realm of human-agent interaction. We have been gradually implementing selected aspects of policy-based coordination within(More)
The International Space Station is one the most complex projects ever, with numerous interdependent constraints affecting productivity and crew safety. This requires planning years before crew expeditions, and the use of sophisticated scheduling tools. Human work practices, however, are difficult to study and represent within traditional planning tools. We(More)
Work SySieiii azalysis afid desigii is Coiiipk and fiofi-deieriiiinistic. In this paper we describe Brahrns, a multiagent modeling and simulation environment for designing complex interactions in human-machine systems. Brahms was originally conceived as a business process design tool that simulates work practices, including social systems of work. We(More)
