Modelling and Analysis of Quantitative Quality Requirements
نویسنده
چکیده
Requirements engineering (RE) is concerned with the identification of stakeholders' needs concerning a future system, the specification of services and constraints that satisfy these needs, and the assignment of the resulting requirements to agents such as humans, hardware devices, and software components. Functional requirements describe what functions must be provided to satisfy the stakeholders' needs, quality requirements describe how well the functions must be provided to satisfy these needs. Examples of quality requirements include concerns such as security, performance, reliability, availability, maintainability, and scalability.

متن کاملModelling of some soil physical quality indicators using hybrid algorithm principal component analysis - artificial neural network
One of the important issues in the analysis of soils is to evaluate their features. In estimation of the hardly available properties, it seems the using of Data mining is appropriate. Therefore, the modelling of some soil quality indicators, using some of the early features of soil which have been proved by some researchers, have been considered. For this purpose, 140 disturbed and 140 undistur...
متن کاملA New Group Data Envelopment Analysis Method for Ranking Design Requirements in Quality Function Deployment
Data envelopment analysis (DEA) is an objective method for priority determination of decision making units (DMUs) with the same multiple inputs and outputs. DEA is an efficiency estimation technique, but it can be used for solving many problems of management such as rankig of DMUs. Many researchers have found similarity between DEA and MCDM techniques. One of the earliest techniques in MCDM is...
متن کاملObject Oriented Notation for Modelling Quantitative Aspects
Nowadays formal methods and analysis techniques in design and modelling of modern computer controlled systems become more and more important. To provide easy-to-use tools for ensuring the overview of complex systems, multi-aspect modelling languages are specified (e.g. the Unified Modeling Language UML). While focusing on best capturing the complex functionality, these languages neglect non-fun...
