LOGISTIČKI INFORMACIONI SISTEM

Abstract

Logistički automatizovani informacioni sistem treba razvijati kao deo jedinstvenog automatizovanog informacionog sistema (JAIS-a). Da bi se logistički automatizovani informacioni sistem uspešno razvijao i primenjivao u operativnoj praksi, neophodno je slediti globalni koncept razvoja JAIS-a i u razvoju više primenjivati timski rad profesionalnog informatičara i poznavaoca realnog logističkog sistema. Bitan uslov za razvoj kvalitetnog logističkog informacionog sistema jeste definisanje informacionih potreba o pojedinim objektima koje tretira logistički informacioni sistem. Zadatak logističkog automatizovanog informacionog sistema jeste da obezbedi: stalni uvid u stanje logističkog sistema; ukazivanje na potrebne i moguće mere poboljšanja; bolje planiranje i upravljanje radom realnog sistema; informisanje ljudstva o stanju realnog sistema i ukazivanje na pravce daljeg razvoja informacionih sistema. Logistički informacioni sistem treba razvijati vodeći računa i o kompatibilnosti sa budućim saveznicima i partnerima. ; A logistics automated information system should be developed as a part of a unified automated information system (JAIS). In order to develop a logistics automated information system and to apply it successfully in operational use, it is necessary to follow the JAIS global development concept and rely more on teamwork of IT experts and specialists in real logistics systems. An important condition for the development of a high-quality logistics information system is to define information needs for particular objects treated by a logistics information system. The task of such a system is to provide: permanent insight into the logistics system, pointing to the necessary and possible measures for improvement, better real system planning and management activities, personnel information about the state of the real system, pointing to the directions of further system development. A logistics information system should be developed taking also into account compatibility with future allies and partners. Defense systems were among the first to accept the challenge (because they were forced to) to introduce information technology in their management system and, with the help of innovations in this area, to increase the performance effectiveness under the conditions of environment dynamic changes. Information technology development mostly followed development of large military projects aimed at solving management or technology issues within military industry complex and management in the most technologically developed defence systems. These science and defense practice efforts resulted in many new methods and techniques such as the method of system analysis and information system design, methods of operational research and simulation, pattern recognition, expert systems for individual processes in management, as well as those for information retrieval and their implementation in decision making. Over time, partial innovations reached a high level of synthesis, leading to new management systems able to function in most complex task conditions. Mastering the procedure of creating autonomous partial information systemswhere the operational research methods helped to optimally apply some of their particular values – has led to the creation of integrated automated information systems for management support. Our recent defence theory and practice have not concentrated enough on logistics information systems in professional journals, neither from the organizational nor from the technological point of view. Experiences gained from operational practice and knowledge acquired by visiting foreign armies, practical needs as well as modern times demands and current trends in the development of defence systems pointed out that it is necessary to pay more attention to this logistics segment in military journals. Logistics information systems cannot be researched, developed and introduced into operational practice (applied) without knowing the structure of high-quality information systems in general. High-quality information systems for supporting the logistic aspects of decision-making and logisticsdealing authorities cannot be developed without properly defining information needs of specific customer information systems and without most precisely describing objects of interest of the logistics system. It is also not possible to go forward in the development and implementation of logistics information systems after long stagnation unless this important area is considered through a retrospective, identifying and defining problems that accompany the development and introduction of information systems in the military forerunners of the Army of Serbia and the AS now and realizing the current situation in this area in the defense system. In principle, our defense system started the work on the automated collection, processing and distribution of information simultaneously with other developed defense systems in the world. However, in the meantime orientations and concepts changed so that no project focused on the development of integrated automated information system (AIS) and decision support system was brought completely to the end. The development of information systems to support the defense system and particularly the Army faced specific dilemmas and problems which hindered their development: information needs of users which information systems should provide for were never properly defined; disputes occurred between "generalites" and "specialists" on whether the system should be built from the bottom (the base) or from the top, resulting in the development of small-scale applications in the base (where problems needing automation occurred) that could fit into a global concept and the development of global concepts never implemented completely into the defense system operational practice. Due to the low level of their information culture, real system experts were not able to properly express and define their needs and expectations of IT professionals who, because of their low levels of general military knowledge, were not able to fully understand the functioning of the real system and information system needs. The above dilemmas and other problems are still present today so that the present automated decision-mking support in the defense system (not just in logistics) does not match the needs of practice, requirements of time and modern trends. In treating logistics information systems in this paper, we will apply an analogy with other information systems. Particular aspects and segments of the development and implementation of logistics information systems will be processed with a high degree of generalization, using the experience and research the authors participated in as well as available sources of knowledge. The aforementioned approach allows for a wider general aspect of the given views, while, on the other hand, gaining the depth and accuracy if validly applied to each specific case and to each logistics system. After the organizational changes in the defense system, and in logistics in particular, due consideration should be paid to the development of information systems since there possibly lies the answer to the request 'to reduce the system response time' within a framework of constant reducing the workforce and 'scope of logistic resources'. Changes in the organization of the technical, health, infrastructural and financial support of Defense represent an additional reason to approach more seriously the issues of defense logistic support and the logistic aspects of decision-making in the defense.
