Lithium battery has been employed widely in many industrial applications. Parameter mismatches between lithium batteries along a series string is the critical limits of the large-scale applications in high power situation. Maintaining equalization between batteries is the key technique in lithium batteries application. This paper summarizes normal equalization techniques and proposed a new type of lithium Battery Equalization and Management System (BEMS) employing the isolated DC-DC converter structure. The system is integrated both equalization functions and management functions by using distributed 3-level controlled structure and digital control technique. With this control method the flexibility of the balance control strategy and the compatibility for different battery strings are both improved dramatically. The experimental results show optimizing equalization, efficiency and the battery string life span has been extended.

Green Management System (GMS) is an effort to protect the environment. With the depletion of natural resources, the protection of the environment is not only limited to a small part of its corporate social responsibility, but it must be a model in business organizations. Model GMS-oriented environment, will systematically affect the company in reducing waste, reducing the use of natural resources, reduce pollution and continuously monitoring the purpose of creating business results that were positive for all stakeholders. Modern business travel will continue to come under pressure from the environment and the realization of the company's sustainability strategy, the managers began to review the possibility of implementation of GMS in the management system of the organization; directs the management of the organization, developing technologies to reduce adverse environmental impact and develop the production of green (green production) more rational and cost-effective. Development and implementation of green policies in environmental management become an important part of the transformation of business management functions in optimizing the use of GMS to improve corporate performance and benefits for environmental sustainability. Direct implications for the development and implementation of environmental protection in the modern business organization in accordance with modern green standards and the principles of environmental sustainability and a company associated with the creation of the organization, program and structure, education and training of human resources will enable the transfer and dissemination of knowledge for environmental protection

One of the reasons that at present in research and production associations and industrial enterprises, according to the degree of implementation, analysis is almost the most backward management function, in our opinion, is still insufficient attention on the part of economic services of these production links to issues of formation of analytical information processing. Having overcome, in principle, the psychological barrier of misunderstanding the advantages of using modern computer technology in production management, the economic services of enterprises in a number of cases have not yet realized that they should be both initiators of the functional development of the management system and direct participants in the new technology for the implementation of management functions, including and analysis function. The use of electronic digital machines in economic analysis is one of the indispensable conditions for achieving its efficiency and complexity. The problem of improving the function of economic analysis is becoming the subject of increasing attention, both from a large number of specialists, and from higher education institutions and various research organizations. The increasing attention to the problem of improving integrated economic analysis is evidenced by the fact that it is the subject of consideration at International, All-Ukrainian, Regional scientific and practical conferences, seminars and is significantly reflected in the recommendations of these forums. At the same time, it should be noted that the methodology of the approach, the breadth of coverage in solving the problem, the focus and depth of development in many cases by different authors are far from the same and not equivalent. Therefore, when conducting an analytical review of scientific publications, in our opinion, it is advisable to evaluate existing developments in a certain order, namely: firstly, works that emphasize the importance and need to improve the function of economic analysis without indicating specific ways to solve this problem; secondly, works examining specific forms of organizing economic analysis in management systems. The latter, in particular, include: works in which the dispersal and implementation of individual analysis tasks are proposed as part of various functional subsystems of the control system; works whose authors consider it possible to combine the tasks of economic analysis with the tasks of other management functions in one of the generally accepted subsystems of the management system; works in which the allocation of analysis tasks to an independent functional subsystem of the control system is justified.

The author?s approach is based on three premises: 1. that Gajo Petrovic?s Praxis was an outstanding phenomenon in Croatian, Yugoslav and European culture, a challenge of freedom in a repressive society; 2. that there has never been such a thing as "Praxis group", "philosophers of practice" or "Praxis philosophers" with a unified philosophical and socio-theoretical orientation; and 3. that political and ideological attacks on Praxis were part of the repressive system that targeted every instance of cultural and scientific dissent. The political leadership of Tito?s regime, its ideological and propaganda apparatus systematically disseminated allegations, denunciations and accusations against Praxis and Gajo Petrovic. The same style has survived through radical historical changes from the appearance of Praxis until today. The attackers have often been the same persons, with the difference that in earlier times they denounced Praxis and Gajo Petrovic as enemies of "socialism" and the "socialist self-management system", and in the changed political fashion as "servants" of Tito?s authoritarian rule. The fate of Praxis in the former regime has been triumphantly interpreted as a "family quarrel". This paper attempts a sociological analysis of the political destiny of Praxis. The analysis is essentially determined not by old and new political and ideological questionings of Praxis, but by Gajo Petrovic?s fundamental belief that there is no freedom without the human or humanity without freedom. .

The enterprise resource planning (ERP) system can integrate the major business management functions of the enterprise with a single common database to allow sharing of all information and achieve efficient communications between management functions. Based on the needs of running a construction enterprise, ERP shows potential applicability to the construction industry. This paper sought to quantify the benefits of ERP systems when applied to construction materials procurement. Specifically, this paper briefly described the business processes involved in construction materials procurement and illustrated how ERP systems could be implemented and the efficiency of the construction materials management system consequently enhanced. The transformation from a non-ERP system into an ERP system through application integration, internal integration, external integration, and automation were simulated. Results show that the individual task improvements of models can increase the productivity of the materials management cycle by up to 5.2%, 18.2%, 27.8%, 13.5%, and 79.2% through internal integration, external integration, application integration, automation, and ERP system, respectively, by automating most of the repeated transactions and reducing manpower required to perform the tasks.Key words: enterprise resource planning, materials management system, productivity, simulation.
