Key research themes

1. How can Problem Structuring Methods be effectively integrated to manage complexity and uncertainty in multi-actor public decision-making contexts?

This research area focuses on the integration of multiple Problem Structuring Methods (PSMs) to address the high complexity, conflicting objectives, and uncertainties inherent in public projects involving numerous stakeholders. It emphasizes developing methodologies that create comprehensive knowledge frameworks of project contexts, enabling decision-makers to reduce uncertainty and manage the potential impacts of the projects prior to engaging directly with stakeholders. This theme is crucial because it advances the practical application of PSMs to real-world, large-scale governance problems where direct actor involvement at early stages may be counterproductive or infeasible.

Key finding: This paper proposes an integrated approach combining Strategic Choice Approach (SCA) and Community Impact Analysis (CIA) as complementary PSMs to create a knowledge framework for complex public project contexts. The... Read more

2. What are the epistemological and methodological foundations distinguishing Problem Structuring Methods (PSMs) within Operational Research and their relationship to participatory and critical systems thinking?

This research theme examines the underlying philosophical and methodological bases of PSMs, situating them within the broader context of Operational Research (OR). It considers how PSMs incorporate constructivist epistemologies, democratic and participatory values, and critical systems thinking principles. Understanding this foundation clarifies PSMs’ role in enabling stakeholders, including marginalized groups, to co-create knowledge about complex problem situations and supports claims for legitimacy, ethics, and empowerment in OR practice.

Key finding: This article argues that Structured Dialogical Design (SDD) qualifies as a PSM by aligning with constructivist epistemologies that emphasize democratic, participatory knowledge co-creation and empowerment of disempowered... Read more
Key finding: Beyond methodological contributions, this paper conceptualizes decision-making as comprising problem-solving, decision development, and decision implementation stages, emphasizing the epistemological need to differentiate... Read more
Key finding: Focusing on conceptual clarity in research methodology, this paper distinguishes between mixed methods (integration of qualitative and quantitative approaches) and multimethods (use of multiple methods possibly within a... Read more

3. How can formal methods and object-oriented programming concepts support methodological rigor and software development processes related to implementing Problem Structuring Methods?

While not PSMs per se, this research theme investigates how formal methods, design-by-contract approaches, and object-oriented software engineering methodologies contribute to the development of robust, reliable, and extensible software systems that can implement PSMs. It includes examination of software modularity, cohesive design (e.g., LCOM metric), inheritance strategies, and integration of code and formal specifications. These elements are critical to creating computational tools that support complex PSM processes and ensure methodological integrity in computer-assisted problem structuring.

Key finding: This work implements refactoring techniques that interoperate with design-by-contract specifications, ensuring class invariants and method pre/postconditions co-evolve with code changes. It demonstrates that preserving... Read more
Key finding: The report establishes the role of formal methods—grounded in discrete mathematics and mathematical logic—in computing education and software engineering, emphasizing their value in verifying software artifacts, including... Read more
Key finding: Evaluating the LCOM metric across three industrial systems, the study confirms its effectiveness in measuring class cohesiveness and identifying well- vs. poorly-designed classes. Since software supporting PSM often requires... Read more

Key finding: This paper discusses unresolved challenges in object-oriented programming including abstraction mechanisms, concurrency, and the need for language-independent conceptual frameworks. The exploration of these issues is relevant... Read more
