The article is aimed at researching the digitalization of business, which will significantly reduce costs, increase both profits and the pace of development of companies. Only digitized companies will be able to promote their goods or services in various spheres of the economy, to develop at the junction of industries at lower costs of finance and effort, because the digitalization allows to erase the so-called «sectoral barriers», creating a completely new segment of the economy. The article examined the essence of the concept of «digitalization» and diagnostics of its possible impact on the development and improvement of accounting systems, analysis, taxation. The analysis of changes and their impact on the development and improvement of accounting-analytical information is carried out, allowing to justify the need for rapid dynamic digitalization processes in various spheres. In addition, the digitalization of accounting-analytical systems will significantly save money by transforming and expanding the duties of relevant officials. Technologically, digitalization allows optimizing a significant number of accounting processes and freeing up accountance workers to perform more important tasks. The research groups the principles of development of accounting and audit systems based on the latest information systems and technologies. Accountants need to go beyond the formation of financial reports that produce information of previous periods, and use technologies of present and future time in order to predict efficient actions and development of the enterprise. In the process of researching the process of digitalization as an inevitable phenomenon in the organization of the accounting process, the authors proved that one of the most promising factors in today’s market is the use of blockchain technologies. Moreover, in the near future, leading firms will introduce blockchain technologies into the accounting and taxation system. The authors present an example of technological application of blockchain in accounting processes, describe the main advantages of using blockchain in the accounting system, which will improve the accounting system, scale it in order to create additional value of the enterprise in the long term.

A unified framework for aerocapture systems analysis studies is presented, taking into account the interconnected nature of interplanetary trajectory design and vehicle design. One of the limitations of previous aerocapture systems studies is their focus on a single interplanetary trajectory for detailed subsystem level analysis. The proposed framework and aerocapture feasibility charts enable a mission designer to perform rapid trajectory and vehicle design trade-offs, and is illustrated with its application to a Neptune mission. The approach can be applied to other atmosphere-bearing Solar System destinations. The framework can be be implemented in an aerocapture software suite to enable rapid mission design studies.

AbstractMany lessons in long-term cropping systems experiments are learned from practical experience. I have conducted large-scale, long-term, multidisciplinary dryland and irrigated cropping systems experiments with numerous colleagues at university and government research stations and in farmers' fields in the USA and in developing countries for 25 years. Several practical lessons learned through the years are outlined in this short commentary. While some of these lessons learned may be intrinsically obvious, results of many cropping systems experiments have not been published in scientific journals due to fatal flaws in experimental design, improper transitioning between phases of the experiment and many other reasons. Ongoing active support by stakeholders is critical to maintain funding for long-term cropping systems studies. Problems and unexpected challenges will occur, but scientists can often parlay these into opportunities for discovery and testing of new hypotheses. Better understanding and advancement of stable, profitable and sustainable cropping systems will be critical for feeding the world's projected 10 billion people by the mid-21st century.

Oil Spill Cleanup

ABSTRACT After four years, significant progress has been achieved in the development of new equipment and techniques for the Navy oil spill program. Utilizing the systems analysis approach, the Navy has undertaken both intermediate and long-term efforts. The intermediate effort developed systems utilizing the best commercially available equipment with Navy-developed techniques. The long-range effort is refining and optimizing the intermediate systems. The intermediate systems and cleanup techniques developed are now operational. Experience, to date, reveals that commercially available equipment is effective when properly applied to a well-defined spill problem. Significant progress is reported which should be of interest to others involved in research and development efforts, those involved in complex port facilities operation, and those involved in development of an effective oil spill cleanup capability.

Wild Life

An organization as big as Unilever (1975 sales were £7000 million) needs to consider the balance of interest between shareholders, employees, customers, government and the environment. Many routine decisions are computerized and no longer of scientific interest. The talk will be concerned with some more complex problems. Decision trees are being used on investment and withdrawal problems. Systems analysis helps us to study the long-term effects of effluents on wild life in rivers. We have the world’s largest private telecommunications network so that managers can have access to current information and we have computer based financial models to enable us to explore the effects of decisions on cash and profit flows.

The paper presents the results of a systems analysis of the reform of Russia’s electric power industry. The analysis has revealed the main problems of the industry and the causes behind them. It has also shown that many of the negative outcomes of the reform are due to the lack of a systems approach to the formulation of the reform goals and objectives and the assessment of their implementation consequences. The lack of a systems approach to crucial problems of the electric power industry in the context of the actual situation and the lack of reasonable development forecasts have led to directive management methods. This significantly reduces the efficiency of the development of the electric power industry in Russia in the medium and long term. The analysis allowed us to propose some priority measures that will not require fundamental changes in the electric power industry but can improve the situation in the medium term.

Selection Of

This paper provides guidelines on how decision-makers can choose capital projects on the basis of economic and financial criteria by applying a systems-analysis approach. Project appraisal, selection and prioritisation criteria are listed, followed by a description of the way in which the result of each appraisal technique should be interpreted. Criteria that should be adhered to in the selection of mutually exclusive projects and the prioritisation of functionally independent projects in order to maximise net output in the long run are supplied. Applications of the proposed investment decision rules are illustrated by examples. Two techniques are proposed that may be used as additional decision-making instruments when evaluated projects show similar degrees of long-term financial viability. Five performance areas that collectively best represent successful organisational logistics performance are detailed.
