The main purpose of this paper is to investigate the application potential of ordered fuzzy numbers (OFN) to support evaluation of\nnegotiation offers.The Simple AdditiveWeighting (SAW) and the Technique for Order of Preference by Similarity to Ideal Solution\n(TOPSIS) methods are extended to the case when linguistic evaluations are represented byOFN.We study the applicability ofOFN\nfor linguistic evaluation negotiation options and also provide the theoretical foundations of SAW and TOPSIS for constructing a\nscoring function for negotiation offers. We show that the proposed framework allows us to represent the negotiation information\nin a more direct and adequate way, especially in ill-structured negotiation problems, allows for holistic evaluation of negotiation\noffers, and produces consistent rankings, even though new packages are added or removed. An example is presented in order to\ndemonstrate the usefulness of presented fuzzy numerical approach in evaluation of negotiation offers.
