This paper analyses the intent of the IEEE recommendations, and discusses the concept of an engineering information system in support of the SEP application for the engineering of computer based systems. Without integration, the independent tools of requirements analysis and management, design modelling, configuration management etc. may end up removing value from systems engineering work.","PeriodicalId":244671,"journal":{"name":"Proceedings IEEE Symposium and Workshop on Engineering of Computer-Based Systems","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126473738","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}

It promotes automatic reasoning and a concept-oriented domain knowledge representation in computer-based systems engineering. The DD, framework is centred around EDDL/sub DP/, a formal but user-friendly language allowing automatic consistency check and property deduction. EDDL/sub DP/ deals with the external outlook of real-world structural and behavioural domain concepts. It offers an expressively adequate set of data, process and object-like concept constructors for a flexible description of the essential domain model of a computer-based system. The DD framework has been explicitly conceived for the development of a new generation of computer-based systems engineering tools endowed with deductive capabilities.","PeriodicalId":244671,"journal":{"name":"Proceedings IEEE Symposium and Workshop on Engineering of Computer-Based Systems","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132808077","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}

Dynamic performance under varying workloads was optimized in terms of system resource parameters in an absolute time base context. The intent was to establish an exacting yet practical means for setting architecture parameters and tolerances near the outset of system-level development. An existing software-implemented prototype for an on-line transaction processing system (OLTPS) was modified and interfaced with a genetic algorithm (GA). An objective function composed of architecture attributes was used as a fitness metric for the GA. Five architecture parameters encoded in a 24-bit chromosome were manipulated by the GA to furnish instantiation values for the OLTPS prototype. After each prototype execution, four dynamic performance measures were fed to the GA for fitness ranking. Despite some hesitancy in GA convergence, the overall optimization scheme worked well. To achieve more rapid resolution of optima, a multiple mutation operator mechanism was improvised and used to advantage. In all, the effort expended for dynamically quantified system-level optimization is seen as well justified and quite beneficial to overall system design.","PeriodicalId":244671,"journal":{"name":"Proceedings IEEE Symposium and Workshop on Engineering of Computer-Based Systems","volume":"78 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133602771","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}

This paper describes the results of an empirical study of the problems associated with change and the approaches taken for dealing with them. It recognises the need for a method for selecting processes and tools from the viewpoint of handling change. A context-driven approach is taken to developing a method for generating a set of criteria tailored to the specific context. Three main strategies for achieving the goal of minimising the adverse impact of change and maximising the benefits of change are recognised: identifying change early in the lifecycle, facilitating the incorporation of change and reducing change. Examples of tactics that support each of the strategies are presented. This model, together with guidelines for its use, constitutes a method for the assessment of requirements engineering and design methods, processes, tools and techniques within their organisational context.","PeriodicalId":244671,"journal":{"name":"Proceedings IEEE Symposium and Workshop on Engineering of Computer-Based Systems","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131206228","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}

Parameter-based representation for modeling complex systems. 2 基于参数的复杂系统建模方法。2

This paper describes a concept for a parameter-based representation (PER) to model complex systems. The representation combines features from both process and object-oriented representations, including IDEFO, data and control flow diagrams, entity relationship attribute (ERA) diagrams, and parameter dependency diagrams. PER applies and extends many concepts that are widely used in software engineering to system-level design. The parameter-based approach provides enhanced capability over existing representations because it represents the multiple attributes of a system-including the performance, physical, design, and process parameters-and explicitly defines the relationships between them. As part of the system design, the parameters are logically partitioned into input, output, and mechanism objects. The relationships between the parameters are captured by behavioral, structural, and class representations. Because PER can represent explicit mathematical relationships between system parameters, it can also be used to develop an executable model of the system. The PER approach assists the systems designer in performing sensitivity and trade-off analysis, assessing the impact of design decisions and changes on system performance, and maintaining design traceability.","PeriodicalId":244671,"journal":{"name":"Proceedings IEEE Symposium and Workshop on Engineering of Computer-Based Systems","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130918725","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}
