A method for assessing the resource intensity of changing the requirements of the purpose when the description of reconfigurable infocommunication systems is incomplete

The increase in the structural and functional complexity of infocommunication systems as a result of scientific and technological progress has led to the formation of multifunctional systems. Under contemporary conditions such systems are characterized by the dynamics of requirements and reconfiguration for these changes. Continuous reconfiguration requires the necessary resources in the planning process to perform the assessments. The aim of the article is to develop an approach to assessing the resource intensity of implementing changes in the requirements of the assignment with incomplete description of the reconfigurable infocommunication system. The main idea of the work is to form estimates of the resource intensity of reconfiguration based on the values of the coefficient of change in requirements. The assessment is performed on the basis of available data on the performance of particular indicators of the requirement system - existing functional components with known resource intensity values. At the same time, correction factors depending on the type of change in requirements and the type of resource, which are specified in the process of changing the multifunctional system according to the criterion of the minimum estimation error, are introduced. The practical significance of the work is to develop a methodology for approximate estimation of resource intensity based on a fuzzy approach in order to take into account the uncertainty of the initial data describing the infocommunication system.
