Innovation for Systems Information and Decision: Second International Meeting, INSID 2020, Recife, Brazil, December 2–4, 2020, Proceedings

How should complex choices be made when evidence is uncertain, priorities compete, or several people must reach a decision together? Innovation for Systems Information and Decision brings research on these challenges into conversation through eight peer-reviewed studies grounded in practical applications.

Edited by Adiel Teixeira de Almeida and Danielle Costa Morais, these proceedings gather work from INSID 2020 on multicriteria decision-making and decision-aid methods. The papers range from decision models and group support to health systems, renewable energy, conflict analysis, and public-sector priorities—showing how rigorous methods can be adapted to very different settings.

Decision methods tested against real questions

The opening contributions examine how to generate criteria weights under uncertainty and how a decision-support system can also help users strengthen their decision-making skills. Another study combines operational-research approaches to analyze a complex health system, while a set of multicultural experiments considers how people work with shared preferences in group decisions.

From quality of life to energy choices

Other papers develop a proposed synthetic quality-of-life index for OECD countries and investigate Stackelberg stability in graph models for conflict resolution. Sustainability enters the discussion through a measurement model for comparing renewable energy sources for a port in southern Brazil. The collection also includes an application of the FITradeoff method to help prioritize special operations of the Brazilian Federal Police.

Eight contributions, one broad field of inquiry

Rather than treating decision analysis as an abstract exercise, the volume connects methods to questions involving health, energy, public safety, quality of life, and strategic conflict. Readers can follow a range of approaches and see how decision models support analysis across disciplines and types of problem.

For researchers and decision-analysis practitioners

This proceedings volume will interest researchers, graduate students, and practitioners working in operations research, multicriteria decision analysis, management engineering, information systems, and related fields. Its varied case settings make it a useful point of reference for readers exploring how decision-support methods are developed and applied.
