Competition among companies is growing globally, with the need to increase productivity and efficiency in the product sector. However, there is also a growing concern about global warming and the depletion of natural resources, as well as their effects on human health. In this context, all human activities that involve intense usage of resources must take into account sustainability as one of the decision criteria. This work presents the application of decision-making methods to define the best product mix in the agricultural machinery industry. With this objective, the current schedule of the production line was identified, along with the production flow, by performing an inventory analysis and an environmental impact study (endpoint). A total of seven alternatives for the production mix of grain trailers were defined, considering different materials and production processes. The selection of the best schedule according to the different criteria was performed through the analytic hierarchy process (AHP) and data envelopment analysis (DEA) to evaluate the managerial implications for decision making. The results obtained through AHP identified a single alternative as being the best, which facilitates the decision making. The DEA method identified two alternatives as the most efficient, and in this case the manager can choose between a product mix that generates lesser environmental impact or greater profitability. Although applied to agricultural industry, the presented methodology can be easily adapted to other activities related to the built environment, such as construction industry.

<p>There is a relation between the environmental impacts to the high emissions in the environment and the natural resources depletion, which can be measured with the useful life of the products, affected by the manufacturing technologies and the sustainable development. In this background, the present article aims to evaluate the environmental impact generated by the manufacturing technology in an agricultural machinery industry, in the grain trailer production, regarding the lifecycle from the cradle to the gate. The study consists in a practical adoption in the industry, where the product and the production flow were identified, the inventory analysis was performed and later the environmental impact was evaluated, considering three categories of ending damage (endpoint): human health, ecosystem and the scarcity of resources, in addition to twenty-two environmental impact categories (midpoint). There is a strong correlation among the use of carbon steel and stainless, the laser machining process and the environmental impact, where the human health damage category is the most impacted in the carbon dioxide element, gas associated to the greenhouse effect. The consumerism of the natural resources for the energy generation is the category which most affected in the scarcity of the fossil resources.</p>

AbstractOver the years considerable research has been conducted on masonry mortars regarding their compatibility with under restoration structures. The environmental dimension of these materials may sometimes be a prohibitive factor in the selection of these materials. Life Cycle Assessment (LCA) is a tool that can be used to assess the environmental impact of the materials. LCA can be a very useful tool in the decision making for the selection of appropriate restoration structural material. In this work, a comparison between traditional type of mortars and modern ones (cement-based) is attempted. Two mortars of traditional type are investigated: with aerial lime binder, with aerial lime and artificial pozzolanic additive and one with cement binder. The LCA results indicate that the traditional types of mortars are more sustainable compared to cementbased mortars. For the impact assessment, the method used is Eco-indicator 95

Theoretical Foundations

In Ukraine, taking into account the constant changes in the economy and policy, the enterprises need to improve management decision-making systems for efficient and well-established production process. Thus it is especially important for the state economy to establish a system of management of the machine-building industry in the field of agricultural production as they: provide the main share of revenues to GDP in Ukraine; are the main source for ensuring the food and agricultural products development. The objective of the paper is to investigate more thoroughly the theoretical foundations of the management decision-making system formation, to develop the direction for optimization under the conditions of uncertainty and risk on the example of agricultural machinery industry enterprise. The theoretical foundations of management decisions at the enterprise as a process for developing and selecting the most effective solution to achieve the best results in the enterprise are outlined in this paper. The factors influencing management decisions such as: degree of risk; information; time; personal qualities of the leader are considered. Methods for application contributing to the most optimal decisions such as: traditional, systematic, economic-analytical, systemic and targeted are identified. Analysis of the current state of agricultural machinery industry development in Ukraine, which shows the dynamics in the direction of deteriorating their condition is carried out. Therefore, there is the need to make management decisions concerning the establishment of their system in management. For example, the agricultural machinery company JSC «Elvorti» is considered. The problem of effective management which requires optimization of directions in the process of making managerial decisions in order to improve its activities is determined. The following factors of the influence on crisis phenomena in the given industry: external factors (political, economic) and internal factors (lack of working capital) significantly affecting the activities results are considered. On the basis of JSC «Elvorti» activity analysis, it is proved that it is necessary to take optimization measures and certain directions in the management decision-making process in order to ensure effective operation. The directions for control, simplification of decision-making process due to automation of document circulation on the basis of 1C, motivation of the personnel which will be able to improve organizational structure of the enterprise and production process are proposed.

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
