When evaluating or ordering alternatives concerning given multiple criteria, decision-makers often use aspiration and reservation levels for criteria, which allows them to define some reference alterna-tives that build a common framework for the evaluation. In this paper, new multiple criteria approach, called distances to aspiration reference points (DARP), is presented, which can be implemented in a specific evaluation or ranking problem when many different aspiration levels should be taken into consideration. One example of such problem is measuring sustainable development of countries or states within the Union. In DARP, to measure the performance of alternative (state), the notion of dis-tances between alternative and individual or common aspiration reference points is used. To manage the problem of different reference points, a modified max-min normalisation technique is proposed. DARP application for measuring smart growth of the EU countries is conducted to demonstrate the effectiveness of the proposed method.

Scoring the negotiation template and building a scoring system for negotiation offers is a starting point for analysis of negotiation. It is usually done by means of a classical additive scoring model. Recent research confirms, however, that TOPSIS may be a good alternative to SAW-based models, since it significantly facilitates the processes of template definition and elicitation of negotiator’s preferences. Fundamental ideas of the TOPSIS, VIKOR and BIPOLAR methods have been analysed and attempts were made to hybridize some of their notions to propose an alternative method for evaluating negotiation offers.
