Multi-criteria Evaluation Of Alternatives Research Articles

Alternative technologies of composite highly loaded of aircraft structures: a qualitative method of making multi-criteria decisions. Part II. Modeling in multi-criteria evaluation of alternatives

The second part of the article is based on the starting points in the decision-making problem (DPR) indicated at the first stage of research [1, point 2.]. Here, the comparison of alternative autoclaved and non-autoclaved technologies for the production of carbon-plastic aircraft structures (AK) of the highly loaded type is continued wing caisson stringer panels (VSP) of B787, A350, MC-21, CSeries mainline aircraft. The main provisions of decision-making theory and a system-process approach with the involvement of practice results are taken as the methodological basis. From the beginning, the following are presented: a scheme for assessing the relative quality of technological process objects; a block-type conceptual model of the subject area of ​​decision-making and its basis; composition of selection criteria and indicators. Based on the above and with the involvement of autonomous dynamic systems (ADS) with discrete time, as well as the theory of the parabola (quadratic function), a formalized model of systemically grouped processes in the evaluation of alternatives is given. On this basis, the study of the essential differences of alternatives with the interpretation of topology ideas (homology groups) was continued to support the adoption of a reasoned final decision in the future, as the goal of modeling this separate side of the functioning of the technical system.

Development of a method of fuzzy evaluation of information and analytical support of strategic management

The method of fuzzy evaluation of information and analytical support of strategic management is developed. A distinctive feature of the proposed method a flexible hierarchical structure of indicators. This allows reducing the task of multicriteria evaluation of alternatives to a single criterion or using the vector of indicators for selection and it provides an opportunity of fuzzy presentation of indicators and compatibility relations between them, which can realize the different nature of relationships. Also, this method allows implementing forward and backward fuzzy evaluation and takes into account the different significance of individual indicators by using the weight of the indicator. The development of the proposed method is due to the need for processing more information and moderate computational complexity.The research found that the proposed method has a computational complexity 10–15 % less than the methods used to evaluate the effectiveness of strategic management decisions. This method will allow evaluating the state of information and analytical support and identifying effective measures to improve the effectiveness of information and analytical support of strategic management. The method allows increasing the speed of evaluating the state of information and analytical support, reducing the use of computing resources of support and decision-making systems, developing measures aimed at improving the effectiveness of information and analytical support. It is advisable to use this method in decision support systems to evaluate strategic management issues

Two-step procedure for multi-criteria choice of generating-capacity structure in remote areas

The paper dwells upon the problem of multi-criteria choice of ways to develop generating capacities to supply power to remote consumers. We herein propose a two-step multi-criteria analysis method: choosing promising power-generation technology first, and then specifying the generating-capacity structure. The paper describes the structure of the proposed multi-criteria methods: the interval TOPSIS method for Step 1; for Step 2, an upgraded analytic hierarchy process based on identifying the structure of the decision maker’s preferences. We demonstrate the use of this method with evidence from the Penzhinsky District, Kamchatka Krai. Thermal power plants, hydroelectric power plants, diesel power plants, as well as solar and wind power are analyzed as power sources. Step 1 includes: analyzing the potential power-supply loads in a specific area; formulating alternative power-generation technology; formulating goals and criteria; criterion-based evaluation of alternative options using objective and subjective models; multi-criteria evaluation of alternatives; analyzing the sensitivity of results and the selection of promising technology. Step 2 includes: formulating goals and criteria on the basis of the selected power-generation technologies; formulating the available alternatives; criterion-based evaluation of alternatives; multi-criteria evaluation and final decision-making.

Determination of the Appropriate Vehicle Operating in Particular Urban Traffic Conditions

This paper presents selection of the most appropriate vehicle intended to operate on a particular urban territory, using the specific methods of multi-criteria analysis. For selecting the suitable vehicle, it is necessary to determine a number of specific criteria. In the paper, the desired vehicle is selected from five vehicles, while, each of them has a different product brand. To determine the weights of criteria, the Saaty pairwise comparison method is applied, and subsequently, the multi-criteria evaluation of alternatives is utilized for a research problem.
