The publication describes how the use of C4ISR architectures in the definition of requirements and analysis of complex systems provides for a conventional description of the domain and for detailed study of the processes in the investigated system. The steps and stages in the description of operational, systems, and technical views of the simulation system are presented. The requirements for the system’s software development are defined on that basis. </style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Todor Tagarev</style></author><author><style face="normal" font="default" size="100%">Petya Ivanova</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Developing an Architecture for Naval Sovereignty Operations Center</style></title><secondary-title><style face="normal" font="default" size="100%">Information &amp; Security: An International Journal</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">C2</style></keyword><keyword><style  face="normal" font="default" size="100%">C4ISR</style></keyword><keyword><style  face="normal" font="default" size="100%">DoD Architecture Framework</style></keyword><keyword><style  face="normal" font="default" size="100%">Enterprise Architecture</style></keyword><keyword><style  face="normal" font="default" size="100%">Environmental Protection</style></keyword><keyword><style  face="normal" font="default" size="100%">Maritime Security</style></keyword><keyword><style  face="normal" font="default" size="100%">Safety of Shipping</style></keyword><keyword><style  face="normal" font="default" size="100%">Sea Surveillance</style></keyword><keyword><style  face="normal" font="default" size="100%">Search and Rescue</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2005</style></year><pub-dates><date><style  face="normal" font="default" size="100%">2005</style></date></pub-dates></dates><volume><style face="normal" font="default" size="100%">16</style></volume><pages><style face="normal" font="default" size="100%">29-37</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">The article summarizes the results of a comprehensive study in support of the acquisition of an advanced C4ISR system for the Navy of the Republic of Bulgaria. A small interdisciplinary team in six months has designed the essential operational views of the architecture of a complex system that provides for maritime sovereignty operations and control of sea traffic. Main challenges, such as lack of development standards, adequate procedures, and doctrinal documents, are briefly described. The approach may be used by NATO and partner countries that envision joint development and acquisition of C2 and surveillance systems.</style></abstract></record></records></xml>
