- The question of investigation is, What can intelligent artifacts mean to a command system? By means of a theoretical synthesis of previous works, the present work starts with an epistemological discussion focused on systems thinking. With the organization in focus, an extrospective approach is taken in which a global discussion results in some implications for the organizational system design. This system is considered as a sociotechnological system; consequently, the nature of systems (i.e., complexity) and the nature of human beings (i.e., parts of the systems and who are to be served by the artifacts) are discussed. The result argues that intelligent artifacts can extend the intelligent behavior of organizations. Examples of computer system architecture and software architecture are given.

- Leadership requires making decisions and implementing the results by influencing those being lead. The Personal Access to Leadership project, PAL, is constructing tools to assist leaders in creative ways and assisting the development of leaders. The tools are knowledge-based systems employing shallow understanding of the domain. The approaches used provide guidance, but do not generate solutions. One aspect that continues under exploration in PAL is the use of stories for training and guiding leaders. In order to make such support systems work, a representation is needed to enable locating useful stories related to the task of a leader. This article defines a model for story representation for the PAL tools, called the PAL tool IdeaLab. The IdeaLab is the tool to which stories are being added, as a help system to support and extend the user's thinking.

Using reengineering for knowledge-based systems
- 2007

Tidskriftsartikel (refereegranskat)abstract
- Reverse engineering, also called reengineering, is used to modify systems that have functioned for many years, but which can no longer accomplish their intended tasks and, therefore, need to be updated. Reverse engineering can support the modification and extension of the knowledge in an already existing system. However, this can be an intricate task for a large, complex and poorly documented knowledge-based system. The rules in the knowledge base must be gathered, analyzed and understood, but also checked for verification and validation. We introduce an approach that uses reverse engineering for the knowledge in knowledge-based systems. The knowledge is encapsulated in rules, facts and conclusions, and in the relationships between them. Reverse engineering also collects functionality and source code. The outcome of reverse engineering is a model of the knowledge base, the functionality and the source code connected to the rules. These models are presented in diagrams using a graphic representation similar to Unified Modeling Language and employing ontology. Ontology is applied on top of rules, facts and relationships. From the diagrams, test cases are generated during the reverse engineering process and adopted to verify and validate the system.

SENSE4US Policy Modelling and Simulation Tool : Evaluation Use Case: Finland’s 2015 Asylum Seekers Crisis

Tidskriftsartikel (refereegranskat)abstract
- A key challenge for policy planning and risk assessment in governmental institutions is to ensure that relevant information, expertise and knowledge are fully integrated and taken into account during the policy process. A systems thinking approach can help gathering and organizing the necessary policy intelligence and involving a diverse range of stakeholders. This study is done as part of a design-science research (DSR) project to build and evaluate a new systems tool for structuring of public policy problems and the design of policy options to be used by policy makers, analysts and researchers in governmental institutions and parliaments. The study aims at evaluation of the tool to establish its utility and efficacy for achieving its stated purpose and assess the end-user benefits. That is performed through application of the tool to analysis of a real public policy problem, Finnish government’s action in response to the rapidly growing numbers of asylum seekers entering Finland in recent years. The resulting simulation model allows designing a pathway for immigration policy that aims to mitigate the resulting problems.

Elements of a documentation framework for agent-based simulation models

- Sufficient and appropriate documentation of a simulation model forms an essential prerequisite for quality assessment as well as for activities of maintenance, reuse or reproduction of the model and its results. This is true for every simulation paradigm. However, in particular for agent-based simulations with their high degree of freedom in design, their usually complex behavior and interactions, high level of detail and heterogeneity, etc, documentation becomes indispensable, but also problematic.This paper contributes to general advancement of the methodological basis of agent-based simulations by presenting a structured way of documenting agent-based simulation models. We propose a documentation framework that consists of six different categories of model information: metadata, informal model characterization, model contents, expected simulation behavior, experimental frame and passed tests.

Image analysis and fuzzy integration applied to print quality assessment

- We present an image analysis and fuzzy integration based option for the assessment of print quality in rotogravure printing. Values of several print distortion attributes are evaluated employing image analysis procedures and then are aggregated into an overall print quality measure using fuzzy integration. The experimental investigations performed have shown that the print quality evaluations provided by the measure correlate well with the print quality rankings obtained from the expert. The developed tools are successfully used in printing shops for routine print quality control.

Reactive tuning of target estimate accuracy in multisensor data fusion

- Dealing with conflicting and target-specific requirements is an important issue in multisensor and multitarget tracking. This paper aims to allocate sensing resources among various targets in reaction to individual information requests. The proposed approach is to introduce agents for every relevant target responsible for its tracking. Such agents are expected to bargain with each other for a division of resources. A bilateral negotiation model is established for resource allocation in two-target tracking. The applications of agent negotiation to target covariance tuning are illustrated together with simulation results presented. Moreover, we suggest a way of organizing simultaneous one-to-one negotiations, making our negotiation model still applicable in scenarios of tracking more than two targets.

Toward Coherent Matching in Case-Based Classification
- 2011

- Building suitable similarity models presents a key issue in developing case-based classification systems. A good similarity model should reflect the real usefulness of a previous case for solving a new problem. This article proposes a new approach to learning of similarity assessments by optimizing local compatibility functions. The goal is to achieve a set of matching functions that are coherent in the sense of most supportive evidences whereas least inconsistence when applied to the case library. The effectiveness of the presented method has been demonstrated by the evaluation results on a set of data sets in the University of California-Irvine (UCI) Machine Learning Repository.
