Study programme requirements engineering system‘s: from automated document‘s management to model-based development process

Summary/Abstract: The Unified Modeling Language (UML) is a modeling language from this field. It has established itself as a worldwide standard. The situation will change with the new Systems Modeling Language (SysMLTM). SysML, which is based on UML, is being increasingly used by systems engineers to model systems. As well as providing system requirements, SysML models can be used to define the system architecture to be used by the software engineers. This article has spelled out how SysML to UML can be used together in the newly developed study program requirements engineering system. SysML provides a general purpose modeling language to support specification, analysis, design and verification of complex systems. These systems may include hardware, software, information, processes, personnel and facilities. SysML reuses a subset of UML 2 and provides additional extensions to satisfy the requirements of the language. The static and structural constructs used in SysML structure diagrams, including the package diagram, block definition diagram, internal block diagram, and parametric diagram. The dynamic, behavioral constructs used in SysML behavioral diagrams, including the activity diagram, sequence diagram, state machine diagram, and use case diagram. Two new diagram types have been added to SysML including the requirement diagram and the parametric diagram. A requirement diagram provides a modeling construct for text-based requirements, and the relationship between requirements and other model elements that satisfy or verify them. In this article in order to familiarize with the models based Model-Driven System Engineering (MDSE) analyzed models based on systems engineering techniques. Systems engineering concentrates on the definition and documentation of system requirements in the early development phase, the preparation of a system design, and the verification of the system as to compliance with the requirements, taking the overall problem into account: operation, time, test, creation, cost and planning, training and support, and disposal. Systems engineering integrates all disciplines and describes a structured development process, from the concept to the production to the operation phase and finally to putting the system out of operation. It looks at both technical and economic aspects to develop a system that meets the users’ needs. This article is devoted to the formulation and implementation of quite novel and interdisciplinary approach to curriculum development that is based on application of systems engineering methods and modern CASE tools. The future improvement of a created system is associated with knowledge-based applications. The presented approach uses the modified Value Chain Model (VCM) to describe the refinement procedure of the problem domain knowledge. Thus, study process parameters derived from VCM can be stored in knowledge databases and later used for solving the problems of expected application areas.
