Comparison of dispersed decision systems with pawlak model and with negotiation stage in terms of five selected fusion methods

Abstract

The article considers the approach in which global decisions are made based on dispersed knowledge. Two approaches that were proposed in the previous papers are considered in this article. One of them consists in direct application of Pawlak conflict analysis model. The second is to use a system with two stages of the process of local models coalitions creation. In both systems, the same fusion methods are used, in order to combine local decisions that were generated by coalitions. The following methods are applied: maximum rule, minimum rule, median rule, sum rule and product rule. The obtained results are compared and conclusions are drawn.
