Agent-based modelling of product invention
This study describes a novel simulation model of the process of product invention. Invention is conceptualized as a process of directed evolutionary adaptation, on a landscape of product design possibilities, by a population of profit-seeking agents (inventors). The simulation experiments examine the sensitivity of the rate of advance in product fitness to the choice of search heuristics employed by inventors. The key finding of the experiments is that if search heuristics are confined to those which are rooted in past experience, or to heuristics which merely generate variety, limited product advance occurs. Notable product fitness advance only occurs when inventor's expectations as to the relative fitness of potential product inventions are incorporated into the model of invention. The results demonstrate the importance of human direction and expectations in invention. They also support the importance of formal product / project evaluation procedures in organizations, and the importance of market information when inventing new products.

OrgSwarm - A Particle Swarm Model of Organizational Adaptation
This study extends the particle swarm metaphor to include the domain of organizational adaptation. A simulation model, OrgSwarm, is constructed in order to examine the impact of strategic inertia on the adaptive potential of a population of organizations. The key finding is that a degree of strategic inertia, in the presence of an election mechanism, can assist rather than hamper adaption of the population.

MEGICO: An Intelligent Knowledge Management Methodology
In this paper, we describe a knowledge management system (KMS) design and construction methodology. For this purpose, section 1 gives a brief introduction that justifies the need for a genuine KMS methodology, like MEGICO. Section 2 very briefly presents MEGICO and section 3 discusses the results and conclusions of its use.

Computer-Assisted Discrepancy Management - A Case Study in Research Transfer to Industry
This paper reports on the “repackaging” and transfer to industry of research results in ViewpointBased Requirements Engineering (VBRE). Our experience, as indicated here, is a particular case of the problems and solutions that small research groups can find in their transfer from theoretical work to practical application. In particular, starting with a formal approach for discrepancy management, we first developed a “light-weight version” of VBRE and empirically validated their most important claims. Then we developed a software tool (discRman) that encapsulates the main points of the approach and, finally, partner organizations used it in small projects. We think that this “theoretical-empirical-light-weight-tool” sequence can be applied in similar situations, especially by small research groups seeking for transfer of their results to industry.

Authorization and Access Control in Adaptive Workflows
In recent years we have witnessed the development of adaptive workflow management systems. These systems offer an extended set of features to support both ad-hoc and evolutionary changes, while ensuring correctness of process definition and their running instances. Ad-hoc and evolutionary changes impose new access control requirements, which have been neglected by adaptive workflow research and are not met by existing models for traditional workflow management systems (WfMSs). In this paper, we extend the role-based access control model for adaptive workflows. This extension is done by defining authorizations for adaptive WfMSs and adaptive authorizations.

A Quality Design Solution for Object Synchronization
This paper presents a quality design solution, the Customizable Object Synchronization pattern, for object synchronization which decouples object synchronization from object concurrency and object functionality (sequential part). The solution described by this pattern provides encapsulation, extensibility, modularity and reuse of synchronization policies.

Workflow Access Control from a Business Perspective
Workflow management systems are increasingly being used to support business processes. Methodologies have been proposed in order to derive workflow process definitions from business models. However, these methodologies do not comprise access control aspects. In this paper we propose an extension to the Work Analysis Refinement Modelling (WARM) methodology, which also enables to determine workflow access control information from the business process model. This is done by identifying useful information from business process models and showing how it can be refined to derive access control information. Our approach reduces the effort required to define the workflow access control, ensures that authorization rules are directly related to the business and aligns access control with the information system architecture that implements the business process.
