Open Access: World leading research into plasma physics...

Strathprints makes available scholarly Open Access content by researchers in the Department of Physics, including those researching plasma physics.

Plasma physics explores the '4th' state of matter known as 'plasma'. Profound new insights are being made by Strathclyde researchers in their attempts to better understand plasma, its behaviour and applications. Areas of focus include plasma wave propagation, non-linear wave interactions in the ionosphere, magnetospheric cyclotron instabilities, the parametric instabilities in plasmas, and much more.

Based on the REF 2014 GPA Scores, Times Higher Education ranked Strathclyde as number one in the UK for physics research.

Abstract

Multi-criteria decision analysis (MCDA) is well equipped to deal with conflicting, qualitative objectives when evaluating strategic options. Scenario planning provides a framework for confronting uncertainty, which MCDA lacks. Integration of these methods offers various advantages, yet its effective application in evaluating strategic options would benefit from scenarios that reflect a larger number of wide-ranging scenarios developed in a time-efficient manner, as well as incorporation of MCDA measures that inform within and across scenario comparison of options. The main contribution of this paper is to illustrate how a more diverse set of scenarios could be developed quickly, and to investigate how regret could be used to facilitate comparison of options. First, the reasons for these two areas of development are elaborated with respect to existing techniques. The impacts of applying the proposed method in practice are then assessed through a case study involving food security in Trinidad and Tobago. The paper concludes with a discussion of findings and areas for further research.
