The enterprise of the future needs to be flexible, adaptive, and to respond rapidly to market demands and opportunities. This, in turn, demands a flexible, adaptive infrastructure. A plausible way to achieve such an infrastructure is to base its organisation on autonomous agents, where each agent responds locally to the intra- and extra-organisational forces it experiences. Enterprise adaptation then arises as an emergent effect. The theories of Holland, and related work on complex adaptive systems, have a direct bearing on the emergence of system adaptation from the interaction of locally adaptive entities. This paper ties Holland's theory of artificial and natural adaptive systems to autonomous agent systems. To illustrate the use of these theories in this context, the paper presents a system of evolving autonomous agents, interacting in a simulated producer/consumer economic world. The paper presents preliminary results with the producer/consumer, evolving agents system, and discusses the implications of these results for evolving, adaptive enterprise infrastructure systems.

A centralised approach to management of distributed systems works well when applied to relatively small-scale systems. As the scale grows, so do the problems of making appropriate system-wide decisions and co-ordinating their execution. As a result, large centrally managed systems tend to be ponderous and rigid. Devolving decision-making responsibility to local units means that locally appropriate responses to changed circumstances can be made rapidly. However, it is quite possible that local decisions in different elements of the system will interfere adversely. How does one co-ordinate local decisions in large systems without re-introducing central control and its associated problems? The decentralised approach adopted here is to craft the interactions between local decision-making elements (agents), in order that effective management of the overall system is an emergent result of repeated local decisions and interactions. The general solution to this problem is an ambitious long-term research goal. This paper presents some results that offer a way forward within a particular class of problem in which the interactions between agents can be modelled as sale and purchase of commodity items.
