Conceptual provisions on the directions of cost optimization of energy industry enterprises on the basis of system, information and project approaches are proposed, which provide for the implementation of procedures for diagnosis and optimization of suboptimal costs and control of the implementation of relevant projects. Diagnosis of suboptimal costs of energy companies is proposed to be carried out using a comprehensive approach to the diagnosis of suboptimal costs based on a combination of information-logical, descriptive-analytical and economic-mathematical models of enterprise analysis, as well as full analysis (vertical and horizontal) of financial statements including P&L, analysis of Cash Flow and financial balance of the enterprise. Applying the appropriate approach allows you to identify the costs that the company can optimize without affecting the quality of electricity and without violating other aspects of the company, which frees up the company to upgrade equipment, additional logistics, reduce electricity costs and implement other projects in within the portfolio. To optimize the costs of energy companies, an appropriate project-oriented approach is proposed, which is based on the use of the method of forming a portfolio of optimization projects using a combination of WSJF model and 6 sigma matrix. The uniqueness of the approach lies in the synergy of the proposed tools and methods and their implementation for energy companies. The proposed approach allows to form a portfolio of interconnected projects, which allows to achieve better financial results through synergies between projects and saves energy companies through more efficient use of its financial resources. Implementation of conceptual provisions on the areas of cost optimization of energy companies allows to reduce the cost of electricity, losses of enterprises and increase their profitability by reinvesting savings in cost optimization projects. Optimization is achieved by diagnosing those costs that can be reduced without affecting quality and in which it makes sense to invest from an economic point of view.

ABSTRACT The use of pre-sprouted seedlings in the implantation of sugarcane crops not only reduces the establishment period and production costs, but also has other advantages, such as a lesser requirement of propagules (stems) and greater phytosanitary control of the seedlings, when compared to conventional planting. Commercial substrates are also expensive and their use increases the cost of seedlings. This study aimed to evaluate the quality of sugarcane pre-sprouted seedlings grown on substrates with different proportions of decomposed babassu palm stem (DBPS), as well as to recommend the substrate formulation that provides the most favorable environment for the growth and development of sugarcane pre-sprouted seedlings. For preparation of the substrate (S), DBPS and soil were used in the following proportions: S1: 0 % of DBPS + 100 % of soil; S2: 20 % of DBPS + 80 % of soil; S3: 40 % of DBPS + 60 % of soil; S4: 60 % of DBPS + 40 % of soil; S5: 80 % of DBPS + 20 % of soil; S6: 100 % of DBPS + 0 % of soil. The use of S2 and S3 considerably improved the seedling quality parameters, such as sprout diameter and length, number of leaves and total, shoot and root dry mass. However, from an economic point of view, S2 is recommended for use.

Objective: To gather and synthesize current evidence that evaluates Pharmaceutical Services in hypertension, from an economic point of view. Methods: A systematic review of articles published from 2009 to September 2020 in PubMed, Scopus, Lilacs and Cochrane was carried out, following PRISMA guideline. Two reviewers screened and selected independently of the studies, extracted the data and assessed the risk of bias. Results: 2,223 articles excluding duplicates were found in the databases. After analyzing the inclusion and exclusion criteria, 12 studies were included, 8 were experimental and 4 were observational. The PS was performed in community pharmacies, outpatient clinics and hospitals, with interventions performed only by pharmacists or in collaboration with other professionals. Most of the interventions were cost-effective, improving clinical parameters and improving the quality of life. Only one intervention did not show significant results in relation to usual care. Conclusion: PS have been associated with positive economic impacts and interventions have significantly reduced direct medical costs. However, there is a need to develop more robust research, such as randomized and controlled studies, in order to allow a more assertive assessment regarding the cost-effectiveness of pharmaceutical services

Perioperative bleeding occupies a leading place among all surgical complications and, despite the rapid development of surgery, remains relevant to this day. In addition to an increase in mortality, bleeding can cause the development of other postoperative complications, which lead to disability of patients and to a decrease in the quality of life in all age groups. Most perioperative bleeding are caused by technical errors. This article reviews the problem of perioperative bleeding from the point of view of impaired coagulation capabilities of the body. The main etiopathogenetic features of hemostasis during the development of this complication are considered. The analysis of postoperative complications, which were directly or indirectly caused by bleeding during or after surgery, is presented. The prevalence of these complications in various areas of surgery has been demonstrated. More detailed study of the hemostasis system and the identification of predictors of hemostasis difficulties before the surgery may cause an improvement in the results of surgical treatment and reduce the number of postoperative complications and the duration of hospital stay. Accordingly, this will lead to a decrease in the cost of treatment and an increase in patient satisfaction with the medical care. In connection with the above, there is a great interest among surgeons and anesthesiologists in preventing the development of perioperative bleeding.

The processes of optimization of the production plan according to certain criteria by modeling were investigated. Achieving effective results directly depends on the optimal production plan. The most important thing in determining the optimal production plan is the choice of modeling criteria. For the most part, the quality of decisions is characterized not by one but by many incomparable criteria. Therefore, it is necessary to make decisions based not on one but on many criteria. This so-called multi-objective optimization problem. For solving such problems is widely used mathematical methods. Mathematical approach can be used to solve problems in any particular activity as mathematics abstracted from specific features characteristic of a particular solution. Therefore, from the point of view of mathematics, the optimal result can be obtained with various established criteria, but from the economic point of view it is important to choose the ones that are of decisive importance. That is, their weight is important for the consumer when making a purchase decision, and for the manufacturer – in terms of production capabilities of certain types and results (production efficiency). The basis of the operation of any enterprise is a production program (production and sales plan). The main task of the production plan is to meet the needs of consumers in high-quality products, which are produced with the best use of resources, on the one hand, and the enterprise to get the maximum profit, on the other. With this in mind, a two-criteria optimization model that allows to make a production plan was proposed. The plan ensures that products are produced with the best use of available resources and at the same time ensures maximum quality of manufactured products and maximum profit from sales of these products. The solution of the problem with two objective functions and linear constraints is achieved by step-by-step solution of the proposed mathematical model of optimization of the production plan using the method of sequential restrictions. The simplex method was also used. An example shows an algorithm for solving the optimization problem.

The study was carried out during summer of 2012 with BARI hybrid tomato 4, planted in the Olericulture farm of Bangladesh Agriculture Research Institute, Joydebpur, Gazipur, Bangladesh to find out the response of plants to some staking and pruning treatments on yield, fruit quality and cost of production. A two factor experiment consisting of three staking methods and four level of pruning, laid out in complete block design with three repetitions. Plants were staked on inverted „V? shaped staking, high platform and string. The plants were pruned to two stem, three stem, four stem and no pruning as control. Results showed that significantly the highest total number of fruits per plant (37.1), marketable fruits per plant (33.7), yield per plant (1.68 kg) and total yield (44.6 t/ha) were produced by the plants having the treatment string staking with four stem. The highest fruit set (43.50%) was found in the plants staking with string having three stems. Plants grown on string staking allowing two stem gave the maximum length (4.71 cm), diameter (4.83 cm) and weight (53.4g) of single fruit as well as maximum fruit firmness (3.43 kg-f cm-2). From the economic point of view, it was apparent that summer tomato produced by string staking with four stem pruning exhibited better performance compared to other treatment combinations in relation to net return and BCR (2.10).Bangladesh J.

The goal of civil engineering has always been the research and implementation of methods, technologies, and infrastructures to improve the community’s quality of life. One of the branches of civil engineering that has the strongest effect on progress is transport. The quality of transport has a profound economic and social impact on our communities regarding trade (freight transport) and city livability (public transport systems). However, innovation is not the only way to improve the features above-mentioned, especially public transport, considering that it is usually beneficial to enhance and repurpose vehicles with appropriate adjustments to offer more efficient services. Other perspectives that influence public transport systems are the costs and times of design and construction, maintenance, operating costs, and environmental impact, especially concerning CO2 emissions. Considering these issues, among the various types of existing public transport systems, those of the so-called Bus Rapid Transit (BRT) offer worthwhile results. The BRT system is a type of public road transport operated by bus on reserved lanes, and it is significantly profitable, especially from an economic point of view, in areas where there are existing bus routes. Nonetheless, for the construction of works minimization, it is closely linked to other features that improve its usefulness, depending on the vehicles’ quality such as capacity, but above all, the propulsion or driving autonomy that would guarantee high efficiency. This paper introduces an analysis of some BRT systems operating worldwide, presenting the background, general technical features, and the correlation with autonomous vehicles.

Although the European rules on water, which are mainly based on the Water Framework Directive (WFD 2000/60/EC), have been in force for many years, the quality of waters in Europe still have huge room for improvement before they can fulfil the objectives set by the WFD and by its “daughters Directive”. Two questions are key here: Are the European rules adequate for this challenging goal? If yes, are the rules applied homogeneously and correctly in European Union Countries or do many issues remain which prevent their full implementation? This article provides a broad overview of water issues in Europe, focusing on the level of fulfillment of requisites from EU legislation and the level of its implementation in Member States. This point of view has been adopted because an uneven implementation of EU laws prevents several European citizens from fulfillment of their right to a healthy environment and a good water resource quality and, furthermore, endangers the level playing field across Europe, from a social and economic point of view.

Regional Solutions

Economic data from 40 years of operation of three regional wastewater treatment companies have been compiled and analysed. The transport systems consist mainly of gravity flow tunnels with lengths of 55–120 km. In spite of the heavy initial investments <20% of the cumulative total costs can be allocated to the transport systems. The treatment plants all remove 90% or more of the influent Biological Oxygen Demand (BOD) and phosphorus and 65–80% of the nitrogen. The wastewater treatment is responsible for about 90% of the cumulative operation costs while the transport system is responsible for 20–40% of the cumulative capital costs. Over time the cost of the transport systems has decreased considerably and is after 40 years of operation only 4–13% of the total costs. Although the main benefit of the regional solutions has been the transfer of wastewater from sensitive inland streams and lakes, the data presented give strong evidence that the regional solutions also has been advantageous from an economic point of view.

Fire resistance of building structures is important not only in terms of prevention of hazards to human health, but also from the economic point of view. The choice of method of fire protection of steel structures depends on the responsible choice of finish or cladding material and suitable technology implementation. Although the assessment of fire risk is a priority, when selecting the decisive criteria we must not also forget the cost of fire protection measures. This article aims at economic comparison of the two fire protection measures for the steel column of rolled profiles.
