TL;DR: In this paper, a convex cell subdivision of the multiplier simplex is proposed to resolve the ambiguity in the virtual multipliers in the polyhedral cone-ratio method when some efficient DMU s' multipliers are employed as the admissible directions of the cone.
Abstract: In this paper, we will discuss subjects related to virtual multipliers in the cone-rati'o model in DEA. Usually, there exists ambiguity in the virtual multipliers in the polyhedral cone-ratio method when some exemplary efficient DMU s' multipliers are employed as the admissible directions of the cone. Firstly, we ,;,ill show a convex cell subdivision of the multiplier simplex. Then, three practical methods for resolving this ambiguity will be presented ·with an example.
