Global decision-making system with dynamically generated clusters

Pawlak's Conflict Model: Directions of Development

“…CONFLICT MODEL PROPOSED BY WAKULICZ-DEJA AND PRZYBYŁA-KASPEREK Around 2009, Wakulicz-Deja and Przybyła-Kasperek proposed conflict model, which is also an extension of the Pawlak model. This concept is described in the papers [26], [27], [28], [29], [30], [31], [40], [41], [42], [43]. Motivation to propose a new model was that, the authors wanted to use conflict model for making decisions based on dispersed knowledge that is stored in many local decision tables.…”

“…The third approach was proposed in the papers [28], [30]. The main modification, compared to the first approach, was conducted within the process of creating a system's structure.…”

“…In the paper [28] the approach is proposed in which not disjoint clusters are created. The cluster due to the classification of object x is the maximum, due to the inclusion relation, subset of resource agents X ⊆ Ag such that ∀ agi,ag k ∈X R + (ag i , ag k ).…”

Dispersed decision-making system with selected fusion methods from the measurement level - case study with medical data

“…An important problem that occurs is to eliminate inconsistencies in the knowledge stored in different knowledge bases. In previous papers the approximated method of the aggregation of decision tables have been used to eliminate inconsistencies in the knowledge [9], [10]. In this paper, we also use this method.…”

“…The use of dispersed knowledge was investigated by the author in the earlier papers [9], [10], [12], [13], [14]. In the paper [10] a dispersed decision-making system with dynamic structure was proposed.…”
