I seek to define rigorously the concept of an emergent phenomenon in a complex system, together with its implications for explanation, understanding and prediction in such systems. I argue that in a certain fundamental sense, emergent systems are those in which even perfect knowledge and understanding may give us no predictive information. In them the… (More)

I seek an understanding of the collective dynamics of systems of agents operating under an optimising dynamic. An autonomous agent has independent agency and decision-making capability. Placed in a system of such agents, however, the consequences of its actions, and hence its preferred choice of action (since it strives to behave optimally) are influenced… (More)
This paper presents the results of our research into the behavior of a dealer-mediated stock market, similar to Nasdaq, by using an agent-based model of the market. We modeled on an individual level the decision-making process of market ma kers (dealers) and investors, as well as explicitly mo deling market i nfrastructure and rules. The model allows… (More)
Strong competition and the high demands of consumergoods companies for just-in-time delivery together with high standards of product and service quality are turning the top end of the corrugated-board box market into a very tough place to be.

In this paper we present the integration of an ant-based algorithm with a greedy algorithm for solving the scheduling of a multi-stage plant. A multi-stage manufacturing plant is comprised of different stages: mixing, storage, packing and finished goods storage, and is an extension of the classic Flow Shop Scheduling Problem (FSP). The algorithmic details… (More)
