The generalized stability indicator of fragment of the network. III Calculating method and experiments

Abstract

In this paper developed a method calculating the generalized stability indicator. Taken into account the classification of critical performance event on the basis of mutual influence within the corporate network. Shows plots of the major dependencies. Complies with the requirements of the model is checked.

The basic approach in designing of the functional safety index for transport infrastructure

“…Here a number of function implemented by subsystem element is denoted by superscript f, a number of investigated economy is m. For example, the following elements can be identified on the current content of path: m = 1 is rails; m = 2 is sleepers and etc. Will then be used approaches previously applied in the works [8][9][10][11][12][13][14][15][16]. Let's introduce an index of functional safety control system of the core defective elements f=1.…”

Mathematical model of sustainability and support of enterprises in organizational networks

“…In order to do this, let's consider the enterprise 0 P without its allocating from the organizational structure of the whole network. The concept of the graded organizational network is introduced in the works [1][2][3][4]. The graded organizational network G is a network which has a homomorphism } ,..., Examples of the graduated networks are networks of the railway subdivisions (distance of a path, departments, major gateways), networks of suppliers of goods and services, required for the transportation process organization, hierarchies of administrative managing authorities.…”

“…The manufacturing situation at the enterprise 0 P will be stable if in this case the enterprise 0 P is provided with required volume of resources to solve the challenges of its manufacturing tasks. Otherwise, when volumes of supplies are less than required by the enterprise 0 P , the manufacturing situation will be critical as in the [3][4][5].…”

Verification of the functional safety index in technical part of transport infrastructure. Railways example

“…where t 1 is a middle time of detecting a defect by monitoring devices (time between adjacent verifications), days. Will then be used approaches previously applied in the works [1][2][3][4][5][6][7][8][9][10].…”
