Модель оцінювання ефективності та вибору автоматизованих інформаційних систем при нечітких умовах

Abstract

Розроблено модель оцінювання ефективності та вибору автоматизованих інформаційних систем (АІС) прийняття рішень у нечітких умовах та запроектовано її програмну реалізацію. Дана модель враховує невизначеність вхідних даних, специфіку функціонування області АІС та оцінює ефективність по фіксованих критеріях згідно міжнародному стандарту ISO 25010:2011. Розроблена модель базується на дворівневій структурі множини критеріїв та їх під критеріїв і відноситься до задачі багатокритеріального вибору альтернатив. У статті розглянуто приклад роботи моделі для оцінювання АІС управління фінансами підприємств. Ключові слова: оцінювання, багатокритеріальний вибір, автоматизовані інформаційні системи, ефективність АІС, міжнародний стандарт оцінювання, управління фінансами.

Modern technologies allowed to simplify the development and operation of automated information systems (AIS) and made possible the creation of complex corporate systems worldwide. Every day the IT industry increasingly develops, by producing a large number of modern technological solutions, which are presented in the form of automated information management systems and decision-making. Nowadays the right choice among the large number of existing automated informational systems is a very urgent problem for any sphere of application. The right choice of effective AIS relies on the security of the company and its successful performance in different spheres.In the article the evaluation model of the efficiency and choice of automated information systems for decision making under fuzzy conditions has been created and its software implementation has been projected. This model accounts for the uncertainty of the input data, the specifics of functioning of area of operation of automated information system of solutions and evaluates effectiveness of fixed criteria according to the international standard ISO 25010:2011. The model is based on a two-tier structure of the set of criteria and relates to the problem of multi choice alternatives. The set of evaluation criteria are classified into two groups: a general, fixed criteria group for assessing ISO 25010: 2011 standards for all areas of operation of AIS decision-making; a set of criteria for assessing, which depends on the area of operation of AIS decision. The set problem of selection can be solved in 3 stages: on the first stage of problem solution, we have to find the aggregated assessments of alternatives including the specifics of AIS decision-making area functioning; on the second stage we have to find the aggregated assessments of each fixed criteria group; on the third stage, having all the evaluations of alternatives by criteria, we build a ranking range for the decision matrix.The method was tested to assess the effectiveness and selection of automated information systems of financial analysis of undertakings in the six products. Evaluations of alternatives by criteria are defined by the experts and are introduced as input data in projected software developed model. The result of this research is the evaluation model of efficiency development and the choice of automated informational systems of decision-making for quality increase in the company functioning (activity). The creation of software, based on created mathematical model will allow companies to improve their own security when purchasing and implementing AIS decision-making (solutions).
