Verification and validation of the comparative vendor score

Abstract

This paper analyzes the components of the linear form that defines the method for evaluating supplier companies. The paper discusses the applicability of the developed linear form to compare suppliers. We present plots of the companies score with the main factors.

The generalized stability indicator of fragment of the network. I. Modeling of the corporate network fragments

“…In [1][2][3][4][5][6] defined stability of a single node based on its interaction with only vendors of various types of resources. It is one of the elements of the complex reference system enterprises [7,8].…”

The generalized stability indicator of fragment of the network. II Critical performance event

“…Critical elementary event is the possible scenarios of work situations that arise due to the impact on the network nodes corporations force majeure, policy-exposure, or nodes suppliers [1][2][3][4][5][6].…”

“…1) in a common network somehow affecting the stability of the nodes [1][2][3][4][5][6], divided into four groups: direct vendors of ܲ , component group Н subnet with priority higher than the priority of the node ܲ , node group H subnet with a lower priority and a group of nodes with equal priority.…”

Mathematical model of the local stability of the enterprise to its vendors. II Research of the node stability

“…The method of calculation the ‫ܭ‬ ௨௧ factor is proposed and substantiated below [1][2][3][4], where ‫ܭ‬ ௨௧ is the instability factor of outside environment of the network model G=(N, A) node j using theory. Research in dependence on suppliers carried out for example in [5][6][7].…”
