Disciplines such as change and configuration management propose methods to maintain system at operational level by incorporating relatively small changes. When major rebuild is required to the system, existing literature proposes to follow the same System Engineering processes as during new system design and development. Systems Engineering, traditionally focused on design and development of new systems, paying limited attention to modernization of existing ones and its processes need to be specially tailored to the modernization of existing system. In the case of straightforward application of Systems Engineering processes, the step of new system formulation is often neglected and considered as something already granted. This paper gives an overview of approaches and methods in the field of system modernization. It proposes a metrics for classification of different types of system modernization. To facilitate system modernization this work introduces a framework based on proposed metrics, Design Structure Matrixes and functional analysis. The framework consists of decomposition and synthesis phases and aims to define new (modified) system, by providing a set of alternatives. The proposed framework anticipates application of traditional System Engineering approach. The paper is illustrated with an example in the field of car retrofitting.","PeriodicalId":192753,"journal":{"name":"2018 IEEE International Systems Engineering Symposium (ISSE)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132857297","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Finite degradation structures are an algebraic framework, recently introduced by the authors, that captures the essential notion of degradation order between the states of a system. They make it possible to describe in a formal way under which conditions a safety model is an abstraction of another one. For this reason, they provide the mathematical ground on which methods to synchronize models designed by systems architects and those designed by safety analysts can be built. We illustrate the proposed approach by means of an example stemmed from industrial practice.","PeriodicalId":192753,"journal":{"name":"2018 IEEE International Systems Engineering Symposium (ISSE)","volume":"115 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131501083","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Such measurements could enable assessing the merits of novel approaches and methods and, ultimately, compare the situations and contexts in which one of them would be preferred over the other ones. Notwithstanding the complexity of such endeavor, this paper presents an elemental decomposition of systems engineering that can be used for characterizing systems engineering methods or approaches. The proposed model builds on understanding systems engineering as the application of strategies to realize systems. The proposed elemental decomposition consists of four elements, which represent the potential effects that any systems engineering activity may have on the system development: set an order on the solution space, change the content of the design space, shape beliefs on the order of the solution space, and shape beliefs on the solution space. Such characterization could eventually be useful to compare the structure and behavior of different systems engineering methods.","PeriodicalId":192753,"journal":{"name":"2018 IEEE International Systems Engineering Symposium (ISSE)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123250102","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We propose TheArchitect, a rule-based system for serverless-microservices based high-level architecture generation. In the process of auto generating serverless-microservices high-level architecture, TheArchitect will preserve the highlighted quality measures. It will also provide a tool based support for the high-level architecture designing process of the software architect. Any software developer will be able to use TheArchitect to generate a proper architecture minimizing the involvement of a software architect. Furthermore, the positives of microservices and serverless technologies have made a significant impact on the software engineering community in terms of shifting from the era of building large monolith applications containing overly complex designs, to microservices and serverless based technologies. Hence TheArchitect focuses on generating best fitted microservices and serverless based high-level architecture for a given application.","PeriodicalId":192753,"journal":{"name":"2018 IEEE International Systems Engineering Symposium (ISSE)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123620187","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The main objective of conducting BIA is to determine the criticality levels of services that are essential to keep the businessup and running. BIA is crucial for business sustainability and failing to define the criticality of the organization’s services and applications leads to improper recovery strategies. However, performing BIA in the traditional way is always associated with several challenges due the nature of business practices and processes that are changing constantly. Automating the data collection of BIA has shown many benefits in capturing the required recovery time objective (RTO) and recovery point objective (RPO) for applications. However, there are numbers of challenges that have been faced during the implementation of such automation. Our approach to conduct BIA exercise consists of seven phases starting with analyzing business need, developing questionnaire, automation implementation, workshops, data gathering, application prioritization, and management approval. This paper describes the importance and challenges of conducting BIA. It shows how an organization could overcome these challenges by automating and centralizing BIA data collection for its applications. Here we illustrate how a BIA exercise is developed and integrated into a centralized data repository for an applications portfolio called MEGA.","PeriodicalId":192753,"journal":{"name":"2018 IEEE International Systems Engineering Symposium (ISSE)","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115899251","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
