Systems Analysis

Systems analysis deals with the study of complex systems  - dynamic systems where people have to make good decisions, sometimes under uncertainty and time pressure. Developing an environmental policy and risk analysis for Stockholm City or investigating how Gotland would be affected by an epidemic flu are two examples of practical problems that can be approached with system analytic methods. 

We conduct research in several branches of systems analysis with roots in many subjects such as mathematics, statistics, philosophy, psychology, and economics. Currently, our main activities are within the areas decision and risk analysis, data mining, and simulation of complex systems.

We study models and computational methods for decision and risk analysis, i.e., tools for making rational decisions by exploring alternatives and consequences in decision situations. The research is conducted within the research network DECIDE Research Group  which consists of nodes at several universities.

Often, even experts have difficulties in formulating models for how probable different outcomes are, something which often is a prerequisite for making rational decisions. Our research within data mining deals with techniques for analysing databases with previously known cases to discover connections that can be used to make decisions in new situations.

Instead of only studying events that have really occurred, you can learn a lot by also studying possible events. Our research aims at generating new methods for simulating complex systems that can be the basis for developing policies and strategies.
