System Measurement and Architectures Techniques

Objetivo

The aim of the SMART project was to support the efficient production of cost-effective fault-tolerant information systems to stated design specifications. Its objective was to define techniques and to provide tools to support the design and development ofsuch systems throughout their life-cycle. This involved:
-identifying the parameters to be measured and processed
-formalising and modelling performance within the reference systems for single components and for structured fault-tolerant systems
-validating the models on existing projects.
The aim of the system measurement and architectures techniques (SMART) project was to support the efficient production of cost effective fault tolerant information systems to stated design specifications. Its objective was to define techniques and to provide tools to support the design and development of such systems throughout their life cycle.

The results were as follows:
A survey of 3 metrics reference systems concerning product, project and process was achieved. The Tools Directory, the Metrics Directory and the Data Directory for the support of the design and development of fault tolerant systems were finished.
A characterisation of fault tolerant architectures (eg in regard to hardware dependability, software design, hardware/software physical description, etc) was made, based on studies of existing information systems for a space shuttle, a nuclear power plant and an airbus.
Performance modelling and quantification were examined.
3 tools were inplemented and are included in the SMART environment, which is a frame server that provides the infrastructure. The frame concept provides a method of describing objects and classes. It manages a set of independent context of clients applications, and its use minimises access to the disk. The tools are:
dependability evaluation tool (MetFac +);
Petri net simulators of real time system functionalities;
fault tree analysis.
The toolkit is open and extensible so that other tools can be added to the SMART environment. Tools and user documents are currently available within the consortium.
The results were as follows:
-A survey of three metrics reference systems concerning product, project and process was achieved. The Tools Directory, the Metrics Directory and the Data Directory for the support of the design and development of fault-tolerant systems were finished. Th e Tools Directory describes currently available reliability and cost estimation tools. The Metrics Directory lists metrics of fault-tolerant architectures with their definitions. The Data Directory defines the entities and relationships which constitute the data model.
-A characterisation of fault-tolerant architectures (e.g. in regard to hardware dependability, software design, hardware/software physical description etc.) was made, based on studies of existing information systems for a space shuttle, a nuclear power-p lant and an airbus.

The frame concept provides a method of describing objects and classes. It manages a set of independent context of clientsapplications, and its use minimises access to the disk. The tools are:
.dependability evaluation tool (MetFac +)
.Petri-Net simulators of real time system functionalities
.fault-tree analysis.
The tool-kit is open and extensible so that other tools can be added to the SMART environment. Tools and user documents are currently available within the consortium.
The demonstrators shown (on dependability safety simulation, fault-trees and Petri-nets), were sufficiently convincing to envisage further industrial cooperation for further tests and dissemination within industry.
Exploitation
The validation of the proposed approach is promoting architecture techniques and associated performance recommendations for the next generation of fault-tolerant systems.
The application of the models and tools that the project is providing has led to increased efficiency in the European fault-tolerant data-processing industry by strengthening project monitoring processes. Improvements in other industries using fault-tolerant software will follow.
Several partners are making internal use of the SMART environment after the end of the project.
