•We propose a transparent system for comparing scenarios on multiple indicators.•Acceptability is based on unacceptable, reasonable and desirable indicator values.•Multi-criteria decision making uses importance weights and compromising between criteria.•A software tool integrates to overall acceptability based on the chosen settings.•A simple example on the sustainability of egg production systems is given.
Choosing between different scenarios commonly requires decision making based on multiple criteria. For example finding the most sustainable agricultural production system requires evaluation of many indicators in fields as diverse as environment, animal welfare and economics. A new and transparent method to such problems based on piecewise linear functions is described, and compared to other approaches. This paper presents a decision support tool which allows to (1) group indicators in a hierarchy, (2) define the acceptability of indicator values between unacceptable and desirable values, (3) define the relative importance of indicators, and (4) combine the individual indicators’ acceptabilities using various degrees of compromising into a final acceptability score for each of the investigated scenarios. The tool contains a visual module to study the comparison of scenarios in the bivariate case, which allows to get familiar with the concepts behind the balancing of indicators. The developed method and software tool are useful for decision support in processes where policy makers and scientists are interacting to arrive at optimal decisions.
