Modeling of Complex Systems Through in SysML in Italian Navy (ITN) Osvaldo Brogi and Nicola Cariello Italian Navy, Italy Copyright © held by the author. ABSTRACT based on model-based design concepts. The model adopted by In the last two years 2014 - 2015 the General Staff of the the Italian Navy use the “constructs” made available by the Italian Navy has been engaged in the definition of a SysML, which outputs are the “explanatory views” that take modernization of the fleet, which led to the acquisition process into account the analysis of the context (e.g. identification of of the following new ITN Ships: stakeholders , the user's need , the application of operational concepts, ...) and the functional analysis (use case diagrams,  1 type LSS units (Logistic Support Ship); sequence diagrams, architectural diagrams). An example of what has been done will be shown in a “case study” that has  1 type LHD units (Landing Helicopter Deck); been realized with the aim of explaining a preliminary design  7 type PPA units (Patttugliatori Polivalenti Altura). of a particular and innovative subsystem of C/S of the new Naval Ships: the Sensor Management System (SMS). The SMS During the design development phases, that has led to the is a subsystem which main purpose is to become the definition of the ship/system architecture and user requirements "Command and Control" system of the radar sensor’s suite of system acquisition, the “traditional” design methodology the new Naval Ships of the Italian Navy. This subsystem, (based, as usual, on a paper-based approach), has been thanks to the functional integration of new sensors of ITN efficiently supported by a more innovative methodology, based Ships, gives the possibility to increase the functionality of each on “model-based” concepts, derived by Systems’ Engineering sensor and to conduct a cooperative search and tracking action, culture. The model adopted, that has been borrowed from the against some particular targets (such as asymmetric threat) that NAF (Nato Architectural Framework) and derived by the are very difficult to detect using “traditional” searching MDAF (Italian Ministry of Defence Architectural Framework), method. is a standardized process that allows to efficiently develop and manage complex systems of systems (SoS) during the entire The use case will demonstrate that the methodology is life cycle (i.e. starting through the user needs elicitation up to absolutely essential if you want to accomplish complex the systems dismissal). The main aim of the NAF’s method is successful systems of systems. In fact, the use of modeling to represent a SoS as a model in which is possible to highlight tools in the development of a project has given the possibility every different aspect of the System through different point of of extrapolating, starting from generic user needs, the real view. Adopting the “model” is then the better way to develop a requirements of the system to a very deep level, that could also system that is the best compromise between performance, time be used in order to directly drive the production process of the and costs highlighting risks and gaps. The NAF’s method system itself. The modelling tool and the method adopted is allows, at the beginning of the development of every new considered essential both in the design, in the development project, to support the Systems Engineer in the definition of the phase and in the rest of the entire system’s life cycle phases. system requirements inside the model starting from the real However, it should also be stressed the fact that what has been understanding of the user needs through the realization of the analyzed and applied to a real case is just the use of a method so called “use cases”. A “use case” is the way in which the and a tool to carry out project activities of systems engineering system satisfies one or more user needs in a practical way (i.e. in a coherent manner. In fact, the tool and its use, without an operative context) understandable from the final user. The internal structured process from both the user/customer side Italian Navy has adopted the previous method and model in and the supplier/producer side is bound to be ineffective. The particular in the definition of the System requirements of the recommendation is that every complex project of SoS should Combat System (C/S) of the new military ships in which, in be developed by every organization by adopting the method comparison with the past, many technological innovations and and the suitable model tools in order to finally get successful new developments have been introduced (e.g. fixed radar products to be delivered to final users. It should be stressed out sensors, infrared search and track S/S, … ). that the product must also be competitive in an international environment where, especially in the big international As anticipated, the operational and technological organization, these kind of method and tools are being used innovation foreseen in the acquisition process of new military since many years. A successful project means a successful ships has required, in particular for some specific areas of the organization. And the sum of the successful organizations Combat System, the use of a more innovative design approach, represents the success of every nation. AUTHOR BIOGRAPHY with the next European one; (ii) cyber defence matter: i.e. the Osvaldo Brogi, Vice Admiral was born on 13 February definition by engineering methods of an innovative single 1955 in Vinci (Florence), Italy. He attended the Naval secure net, where the cyber community accesses management Academy in Livorno from 1974 to 1978, achieving a master’s and the net efficiency monitoring is guaranteed by an effective degree in Electronic Engineering in April 1981 at Pisa governmental “Computer Emergency Response Team – University. Since October 2010 and until June 2012, he was CERT”; (iii) design activities about the ship new buildings: i.e. appointed Director of Military Shipyard of Augusta. Navy engineering feasibility studies for the technical operational Arsenal in Augusta (Sicily, Italy) is one (out of three) of the requirements and for the preliminary architectures of the naval main Italian Navy Arsenals, in charge of the whole lifecycle operating systems by the “Ministry of Defence Architectural maintenance of the Navy Units assigned in Sicily area. The Framework – MDAF”. Since December the 30th 2013, Vice Arsenal is an autonomous Command, roughly budget 20M€, Admiral Brogi is the Head of the Naval Weapons Corps which equipped with several civil infrastructures like dockyards and main task is the governance of the resources employed for the 500 personnel assigned (both civilian and military). The design of the Naval Operating Systems/Combat Systems and Arsenal has been supporting UNIFIED PROTECTOR sea their logistics support. operations for 5 months. It was a great experience where Nicola Cariello was born in Bitonto (BA) on the 14th of leadership and initiative sense were prevailing. He also the December 1975. He was normal course cadets at the Naval Chairman of Bluemassmed Tech Group (2008÷2012), an Academy (years 1995-1999) and then promoted to Ensign in European Project to develop Common Information Sharing 1999. He graduated from the University of Pisa in Environment/Maritime Situational Awareness (CISE/MSA) Telecommunication Engineering in 2002. He was head of amongst EU States. He managed more than 500 experts Technical Operations component and Weapons Technician one belonging to 37 administrations of 6 Member States and played on board ITS DDG "Durand de la Penne" (August 2002 - the important role in promoting multinational cooperation December 2005) and promoted Lieutenant in 2003. He got • through a concrete exchanging of the Mediterranean MSA master's degree in Systems Engineering from the “Tor using new C3 systems developed in Service Oriented Vergata” University - Roma. Currently he is in service with Architecture (SOA).
