The results show that the proposed method could reflect the judgements of decision makers more precisely, and make use of evaluation information more comprehensively.
The main contribution of the presented methodology is that it enables to determine the relative importance of the factors used in performance evaluation based on the subjective judgements of decision-makers, which is one of the most important steps of performance evaluation studies.
Focal element set (FES) S m is a subset S m ⊂ U, in which the number of elements is denoted by m, e.g. S1 = {s α } or S2 = {s α, s β } or S3 = {s α, s β, s γ }..., where α ≠ β ≠ γ and α, β, γ = 1, 2,..., M. Set S m reflects the uncertainty of decision judgements.
SDT has been applied to many areas of judgement and decision making [ 28] since its initial application to communication and psychology [ 29].
We report on the role of task difficulty elsewhere [ 26].> This exploratory study revealed that time pressure had little effect on the quality of judgement outcomes in a simulated acute care setting; a finding that contradicted results from other psychological studies [ 27– 29] where time pressure was shown to produce a significant reduction in the quality of judgement and decision making.
This approach has been used successfully to investigate the cognitive bases of judgement and decision-making of an individual in naturalistic settings in environments from system development to intensive care units [ 16, 17].
It is also one of the most challenging areas of professional judgement and decision making in social care [ 4].
Additionally, SC is the consciousness of one's own projects [ 39] and so it is, at once, an instance of anticipation, judgement, and decision.
After this analysis, it is possible to analyse different elements of the judgement and decision process (e.g. the information used to inform the decision) and to map the order in which elements of the decision process occur [ 36].
Such sociometric relationships [8] can be revealed through various data collection methods, ranging from prescribed communication lines, and subjective judgements of reputation, to the observation of decision or general interaction processes [9].
