Reducing incompatibility in a local AHP-group decision making context

Abstract In the context of local analytic hierarchy process-group decision making (AHP-GDM), this paper presents a theoretical framework and semi-automatic procedure for reducing incompatibility between actors involved in process collective position. The row geometric mean is employed as prioritisation compatibility index ( $$\textrm{GCOMPI}$$ GCOMPI ) measure; individual pairwise comparison matrices are considered input reduction process, whilst vector output. attained by slightly modifying, relative terms, judgements matrix, irrespective method used to obtain it, that further improve . resulting matrix associated priorities close initial values. does not modify simplifies reaching consensus. A simulation analysis utilised study performance algorithm along with an illustrative numerical example. proves proposed easy implement efficient, it provides mathematically closed results significantly reduces precise consistency consensus which one AHP-GDM tools. allows be adapted specific interests.
