dealing with life-threatening situations requires the quickest, most effective response. each time the emergency phone number 115 is dialed, ems is ready to act and dispatch the rescue services needed. whether it is a fire, road accident, crime or medical crisis, the caller in distress should receive support from emergency services and lives should be saved. to be able to meet the required resp...

SoS Models used for SoS design and requirements elicitation. At runtime operations SoS is under failure risk that resulted from its emergent behavior due to its constituent systems autonomy and system complexity. In order to mitigate SoS failure effects and prevent SoS failure we propose SoS model extensions and system failure prediction and prevention framework that enhance the usage of SoS st...

One of the principal value propositions for the creation of Systems of Systems (SoS) is the ability to generate stakeholder value beyond that which can be delivered by a single system or even a collection of systems. The dynamic interactions among the component systems in a SoS make conceptual design decisions for SoS more complex compared to traditional system design. There are several heurist...

Model Based Systems Engineering (MBSE) follows a model centric approach in contrast to the traditional document centric approach. The complexity of SoS development lends itself nicely to a model centric approach, especially a model that can represent the independence of the systems that comprise the SoS. An agent-based model provides a framework where the SoS and each system are independent ent...

Previous papers have described a computational approach to System of Systems (SoS) development using an Agent-Based Model (ABM). This paper describes the Fuzzy Decision Analysis used in the negotiation between the SoS agent and a System agent in the ABM of an Acknowledged SoS development. An Acknowledged SoS has by definition a limited influence on the development of the individual Systems. The...

System of Systems (SoS) is a subject of interest for many researchers from different research lines. System of Systems Engineering (SoSE) deals with many challenges mainly in the activities related to requirements. In order to explore studies related to Requirements Engineering (RE) for SoS, this Systematic Literature Review, using the Snowballing approach, aims to answer four research question...

Today’s need for more complex, more capable systems in a short timeframe is leading more organizations towards the integration of existing systems into network-centric, knowledge-based system-of-systems (SoS). Software and system cost model tools to date have focused on the software and system development activities of a single software system, but none to date adequately estimate the integrati...

Chromosomal DNA is exposed to continuous damage and repair. Cells contain a number of proteins and specific DNA repair systems that help maintain its correct structure. The SOS response was the first DNA repair system described in Escherichia coli induced upon treatment of bacteria with DNA damaging agents arrest DNA replication and cell division. Induction of the SOS response involves more tha...

The SOS system and SOS mutagenesis are frequently studied, or exploited to obtain an increase in mutagenicity of bacteria. Here a short survey is made of the phenomenon of SOS response with special attention to latest and less discussed data, especially the induction of the SOS system in response to cell starvation or mutation of certain genes and the role of inducible DNA polymerases.

Systems of Systems (SoS) are a current focus of many organizations interested in integrating assets and utilizing new technology to create multi-component systems that deliver value over time. The dynamic composition of SoS along with the managerial independence of their component systems necessitates systems engineering considerations and methods beyond those of traditional systems engineering...
