Quite frequently one has to solve variant synthesis multicriterial selection problems in construction. These problems consist of many technical-organisational solutions interacting with each other. The solution of each problem can be made of two or more alternatives. In each step k according to j, the effectiveness criterion is selected from variants i. Using the entropy method the weights of effectiveness indices in each step are calculated. By the criterion k(1) the effectiveness of variants in each step is determined. From the row of priorities obtained the first two variants are selected and they are repeatedly calculated by the same methods. The selection of variants (branches) synthesised is made by the criterion Ωs (2). A priority row of variants is determined according to the rule that the greater value of Ωsmeans the best variant (3). The second algorithm is used when there are more than two variants in the steps of problem. A joint matrix between separate steps of solutions is determined. Weights of criteria for each step are determined using the entropy method. It is necessary to regulate the values of importance according the number of variants. The weights obtained by the method of entropy are multiplied by the coefficient considering the number of alternatives analysed (4). The final valuation of branch is obtained according to the formula No 5. The best synthesis result is the one, having the largest Ωs value. The values of criteria effectiveness of each step of each net program branch are summed, when priorities are determined using the same coefficients of effectiveness. The weights are summed using formula 6. It is possible to calculate the priorities of alternatives using the ideal point method. The methods mentioned above were used to solve real life construction problems.

Theofogicaffy, Islam is one and absolutely correct. However, historicaffy, after being understood and translated into the real life, Islam is not single, but various or plural that manifests at feast in three schools of thoughts: Traditional Islam, Revivalist Islam (fundamentalism), and Liberal Islam (Progressive). The group of Jaringan Islam Liberal (JIL) represents the fast school of thoughts. Even though it is stiff young (ten years), JIL becomes populer because it frequentfy proposes the new thoughts that often evoke controversions in the community. The reformation of thoughts proposed by JIL covers four areas: first, reformation in politics. In this context, JIL gives a priority to the idea of secularism; Second, reformation in socio-religion. Dealing with this, JIL proposes the concept of pluralism; Third, reformation in individual freedom. In this case, JIL gives a priority to the idea of liberalism both in thoughts and actions;fourth, reformation in women. Regarding this, JIL proposes the idea of gender equaliry. This reformation thought of JIL receives pro and con in the community. On the one hand,some of them panne and fulminate it; on the other hand, the other ones support and give appreciation. In such situation, JIL grows as a thought and Islamic progressive movement in Indonesia. Key Words: Islamic Thought, JIL, Secularism, Pluralism, Liberalism, and Gender Equality.

Supplier selection is one of the critical decision-making problems in supply chain management. The purpose of this research is to investigate the process that is commonly used for calculating a “score” for each supplier when certain attributes are used. In decision making theory, the selection of “best” alternative can be done under three different conditions: certainty, risk, and uncertainty. Most of the current research uses “certainty” conditions. This article suggests that the “uncertainty” condition should be used in supplier selection as it corresponds to real-life more than the certainty or risk condition. “Maximum entropy” method is used to ascertain the probability function of the outcomes. Once the probability functions are known, means and variance can be calculated, and the suppliers can be evaluated.

Different spheres of application of TOPSIS methods are considered by the author based on the literature review. The characteristics of TOPSIS methods for the selection of electricity supplier in Ukrainian energy market, which was launched in 2019, are studied in the article. The proposed methodological approach could be used by the enterprises, which consume electricity, buying it from suppliers on the energy market. The general problem statement for multi-criteria optimization in order to evaluate electricity suppliers is formulated by the author. The main stages of the TOPSIS method procedure are considered in the article, among which are identification of decision matrix, normalization of decision matrix, calculation of weighted normalized decision matrix, identification of “ideal” and “ideal-negative” expected state, distances calculation and calculation of related proximity to the “ideal” state. According to the obtained indicator of proximity the ranking of the researched objects should be conducted. It is highlighted in the article that the cost factor does not have significant influence in the process of the electricity supplier selection. The indicators, according to which the assessment of electricity suppliers is carried out, are given. The author proposes to use the indicators of enterprises’ efficiency, business activity, solvency, as well as financial results and profitability. Among these indicators the author identifies stimulators and destimulators, the maximization or minimization of which serve as criteria for managerial decision-making. The weights of the criteria are identified using the entropy method, which gives objective results comparing to the methods, which use experts’ opinions. The application of the proposed methodological approach is carried out in the article on the example of 43 enterprises. The obtained indicator of relative proximity to the ideal object allowed ranking the researched enterprises. The best and the worst alternative of electricity suppliers are identified, which could be used in the process managerial decision-making.

Abstract.-This article attempts to demonstrate that the work of Piero Sraffa –especially Production of commodities by means of commodities-is the greatest revolution in economic analysis. The novelties introduced by the Italian economist, against all classical and marginalist traditions, such as considering the surplus of reproducible goods as the object of the economy, the intersectoral relations between goods and services on the one hand and processes on the other, the prices formed as a margin on costs, reduction of capital to dated work, the selection of techniques and the considerations about of the joint production support the above statements. To this we can add other more questionable or more or less significant as the standard system, its theory of fixed capital, the considerations on land and mines, the differentiation between basic and non-basic goods. Some of these analyzes have precedents or are contemporaries (physiocracy, Ricardo, Leontief), but the whole of them supposes this revolution made in the economic analysis and supposes for this the ideal model to be candidate to base any economic analysis worthy of such name. Keywords: Sraffa, economic analysis, theoritical revolution Resumen.-En este artículo se intenta demostrar que la obra de Piero Sraffa –en especial Producción de mercancías por medio de mercancías- supone la mayor revolución del análisis económico. Las novedades introducidas por el economista italiano contra toda tradición clásica y marginalista tales como considerar el excedente de los bienes reproducibles como objeto de la economía, las relaciones intersectoriales entre bienes y servicios por un lado y procesos por otro, los precios formados como un margen sobre los costes, la reducción del capital a trabajo fechado, la elección de las técnicas y las consideraciones sobre la producción conjunta avalan las afirmaciones anteriores. A ello le añadimos otras más discutibles o más o menos significativas como el sistema patrón, su teoría del capital fijo, las consideraciones sobre la tierra y las minas, la diferenciación entre bienes básicos y no básicos. Algunos de estos análisis tienen precedentes o son coetáneos (fisiocracia, Ricardo, Leontief), pero el conjunto de ellos supone esa revolución que hace del análisis económico de Sraffa como el modelo idóneo para ser candidato a fundamentar cualquier análisis económico digno de tal nombre.

There seems to be a general agreement amongst practitioners of economic evaluations, including Health Technology Assessment, that the explicit statement of a perspective is a necessary element in designing and reporting research. Moreover, there seems also to be a general presumption that the ideal perspective is “societal”. In this paper we endorse the first principle but dissent from the second. A review of recommended perspectives is presented. The societal perspective is frequently not the one recommended. The societal perspective is shown to be less comprehensive than is commonly supposed, is inappropriate in many contexts and, in any case, is in general not a perspective to be determined independently of the context of a decision problem. Moreover, the selection of a perspective, societal or otherwise, is not the prerogative of analysts.

Owing to the heterogeneity and inherent uncertainty of services, the selection of service suppliers is a complicated multi-attribute group decision-making (MAGDM) problem in which fuzzy criteria and stochastic criteria coexist. During the past few decades, many real-world supplier selection problems have been resolved using MAGDM methods. Nevertheless, extant research on supplier selection considers either fuzzy criteria or stochastic criteria, and hence most of these methods cannot address the complex and unstructured nature of contemporary service supplier selection problems. In this study, a novel technique for order preference by similarity to the ideal solution (TOPSIS) approach, integrating both fuzzy criteria and stochastic criteria, is developed; in this approach, the interval-valued intuitionistic fuzzy (IVIF) cross-entropy for fuzzy criteria and the Euclidean distance for stochastic criteria are used to acquire the rankings of alternatives. Moreover, a sensitivity analysis is conducted for a case study of hoisting service supplier selection, and a comparative analysis with other existing methods is performed to confirm the effectiveness and efficiency of the proposed approach.

The classification of surrounding rock stability is the critical problem in tunneling engineering. In order to decrease engineering disasters, the surrounding rock stability should be accurately evaluated. The ideal point method is applied to the classification of surrounding rock stability. Considering the complexity of surrounding rock classification, some factors such as rock uniaxial compressive strengthen, integrality coefficient of rock mass, the angle between tunnel axis and the main joint, joints condition, and seepage measurement of groundwater are selected as evaluation indices. The weight coefficients of these evaluation indices are determined by the objective and subjective weighting method, consisting with the delphi method and the information entropy theory. The objective and subjective weighting method is exact and reliable to determine the weights of evaluation indices, considering not only the expert’s experiences, but also objectivity of the field test data. A new composite model is established for evaluating the surrounding rock stability based on the ideal point method and the objective and subjective weighting method. The present model is applied to Beigu mountain tunnel in Jiangsu province, China. The result is in good agreement with practical situation of surrounding rock, which proves that the ideal point method used to classify the surrounding rock in tunnels is reasonable and effective. The present model is simple and has very strong operability, which possesses a good prospect of engineering application.

Smartphones are a primary need for all upper class and lower class people. As these needs are many smartphone vendors that offer different prices, features, systems and technologies at competitive prices. Many people want specifications that are capable but limited in financial terms. This causes smartphone users not to be able to make the right choice according to their needs because the frequent selection of smartphones is based on prestige and consumer consumptive behavior. The TOPSIS method is a multicriteria method used to identify solutions from alternative sets based on simultaneous minimization of the ideal point distance and maximizing the distance from the lowest point. The expected results can be input to potential smartphone buyers in accordance with their finances and qualified specifications.Keywords: Decision Support System, Topsis Method, Smartphone.

Modern materials and technologies for strengthening drainage and upland ditches, their advantages and disadvantages are considered. When choosing the type of reinforcement, the railway design engineer must compare the options for the types of reinforcement of ditches in terms of various criteria: reducing labour and resource intensity, duration of construction work, increasing durability, improving environmental friendliness, the need for special equipment, and others. An ideal point method is proposed for solving a multicriteria deterministic problem of choosing the type of ditch reinforcement. A prototype program of the decision support system for choosing the type of reinforcement using the ideal point method has been developed. The program contains four areas: the source data area; the calculation area; the guide to the types of ditch reinforcement, which separately identifies innovative types of ditch reinforcement; the area of calculation results and recommendations. With the help of the program, the test problem of choosing the type of reinforcement is solved. Of the three alternatives, a concrete roadbed is recommended-an innovative strengthening of the ditch.

Selecting the right candidate for the right cause is similar to identifying the most compromising solution of multi-criteria decision making (MCDM) problem. In real life the selection criteriamay involve vague and incomplete data which cannot be expressed in precise mathematical form or numerical values. Apparently fuzzy-based technique can be applied to describe and represent these data in fuzzy numbers. This paper presents a MCDM fuzzy TOPSIS based model designed to solve the selection problemfor allocation of government staff quarters. Result shows that the proposed model is suitable and appropriate. It was also found that the MCDM model which uses single decision maker rating process can also be applied to multiple decision makers. It is recommended that the application of fuzzy TOPSIS can be extended to other selection processes such as vendor selection, training evaluation or group marking of project works.
