The problems of choice of enterprises-recipients of scarce investment resources for the projects of production capacities modernization are considered. The enterprises’ management shows their opportunistic behavior, seeking to request the excess investment amount. Investment projects often do not have economic justification, and new-built modern production facility will not be used efficiently. At the same time, more careful selection of recipients leads to delay in modernization projects’ implementation, reducing the potential savings in production costs. In the paper we propose simple methods of assessing losses arising from restricted rationality of the resources’ dispatchers in the allocation of funds to enterprises that are unable to ensure effective capacity utilization, as well as losses due to the time lag in the decision making. This allows you to develop cost-justified recommendations for improving the processes of decision making. All models are designed to use only available statistical information. The calculations are performed taking into account economic specificities of the aviation industry, but the proposed approaches can be adapted to other industries that are experiencing similar management problems.

Abstract Investing is a category of spending that engages the future most, depends on increasing and improving the productive potential of an enterprise (through expansion and modernization), the emergence of new production capacities. Because it is necessary to allocate large resources for the investment process, they are for a long time and the decision making process involves a lot of uncertainties. A decision on investment projects must be based on a careful analysis of all aspects of the context, the variables involved and their dynamics.

The socio-economic objectives of transport projects are generally related to the improvement of travel conditions for goods and passengers as well as the improvement of the quality of the environment and the wellbeing of the served population. Railways infrastructure projects are always complex because of the many variables involved. In railway rehabilitation, in particular, social, economic and environmental variables take on considerable importance. These variables contribute strongly to the selection of the intervention project to be performed. Historically, multicriteria evaluation methods were developed to select the best alternative from a set of competing options. Multicriteria Analysis is applied for comparison of alternative projects, allowing taking into account different criteria simultaneously. It presents a framework in which all the stakeholders can participate actively in the process of decision making and in the explicit resolution of problems. The paper intends to frame the multicriteria analysis with the purpose of its implementation in railway investment projects concerning rehabilitation interventions. In this sense, its importance and potential will be highlighted for several stakeholders in the decision-making process, as well as the objectives and criteria definition for a practical implementation.

Abstract. The construction industry is exposed to high risks, which cannot be ignored in case of large investments. The choice of a reliable investment and construction project is important for the success of the investor. A reliable choice of investment and construction project requires taking into account many uncertainties for decision-making. The investor has to be aware of the risks related to the implementation of investment and construction projects, as well as the level of involvement of all the uncertainties in the overall risk of investing in a particular project. These factors may be related to the economic environment, the public policy, mood of the social environment, the market, etc. Accordingly, factor-based decision-making is a vital process that should be considered when alternative investment and construction projects are being assessed. As the construction industry is characterized by long investment cycles, it is a dynamic, complex system with uncertain, incomplete data, as a consequence of a fundamental practical problem when applying investment-selection models construction projects are to determine the distribution of uncertainties to calculate the reliability of the projects. More recently, most approaches to pre-selection investment and construction projects have been presented using linguistic estimates instead of numerical values. This article presents a multi-criteria decision-making methodology for analysis and selection of the most reliable investment and construction project under the conditions of risk and uncertainty. This approach is based on the theory of fuzzy sets, which has the advantage of using linguistic estimates and precise for qualitative and quantitative assessments respectively.

In today's world, with ever-increasing safety requirements, there is a growing demand to maintain or reduce production costs. In aviation, in addition to factors like weight and related variables such as resistance to vibration, corrosion, temperature and other are also considered. The task of this paper is to analyse unconventional designs of wing beams with respect to the current requirements of the aviation industry. In the article, the authors analyse the possibilities of design modification either by adding ribs to the profile, or by changing the cross-section of the profile itself. In practice, such design changes would increase weight, production time and finances, but also increase strength and thus safety. All proposed changes were subjected to strength analyses by FEM (Finite element method) computer simulations. The article output is the selection of suitable designs for further observation and experimental verification to ensure comprehensive results for the possibility of implementation in practice. Despite the non-traditional shapes of the proposed wing beam cross-sections, the authors assume that traditional beam shapes will be gradually modified more efficiently.

The head of the environment is an extension of the head of the village head in assisting or providing services to the community both in the administration of administration in the village and to other problems. It is natural for a kepling to be appreciated for their performance during their special tenure in the kecamatan field area. Previously, the selection of a dipling in a sub-district was very inefficient and seemed unfair for this exemplary selection to use a system to produce an accurate value, and no intentional element. To overcome the process of selecting an exemplary kepling that experiences these obstacles by using an application called a Decision Support System. Decision Support System (SPK) is a system that can solve a problem, and this system is also assisted with several methods, namely the Rank Order Centroid (ROC) method that can assign weight values to each of the criteria based on their priority level. And to do the ranking or determine an exemplary set using the Additive Ratio Assessment (ARAS) method, this method provides decision making that takes decisions based on ranking or the highest value.Keywords: Head of Medan Area Subdistrict, SPK, Centroid Rank Order, Additive Ratio Assessment (ARAS).

The teacher is a major milestone in the world of education, the ability and achievement of students cannot be separated from the role of a teacher in teaching and guiding students. Based on the Law of the Republic of Indonesia No. 14 of 2005 concerning Teachers and Lecturers, in Article 1 explained that teachers are professional educators with the main task of educating, teaching, guiding, directing, training, evaluating, and evaluating students in early childhood education through formal education, basic education and education medium. Whereas in Article 4 of the Act, it is explained that the position of teachers as professionals serves to enhance the dignity and role of teachers as learning agents to function to improve the quality of national education.Decision making is an election process, among various alternatives that aim to meet one or several targets. The decision-making system has 4 phases, namely intelligence, design, choice and implementation. These phases are the basis for decision making, which ends with a recommendation.The Preferences Selection Index (PSI) method is a rarely used decision support system method. This method is a method developed by stevanie and Bhatt (2010) to solve the Multi Criteria Decision Making (MCDM). With the right consideration, this method can be one of the tools to determine policies in decision-making systems, especially the selection of outstanding teachers. Determination of policies taken as a basis for decision making, must use criteria that can be defined clearly and objectively.Keywords: Decision Support System, PSI, Selection of Achieving Teachers
