Development Verification

One of the ideas under investigation concerns a reasonable use of formal methods. Experience of using the formal way of systems development, verification and its quality assurance is extending. Formal methods, in general, are used for ... 

Considering the continued development, verification and improvement of these aerial spray modeling techniques and their acceptance by the U. S. Army and U. S. Forest Service, we believe the concepts deserve wider use in civil spray operations, pesticide development programs and environmental assessment studies. We therefore welcome the opportunity presented by this symposium for discussing the mathematical framework of the models and to illustrate their applications. 

In design and development, verification concerns the process of examining the result of a given activity to determine conformity with the stated requirements for that activity. 

R D of hydrogen production is also successfully proceeded improvement of system efficiency, and development, verification of system analysis code etc. Also, a pilot test program to produce hydrogen at a rate of 30m /h by using the IS process (6) will be started in tlie 2nd half fiscal year of 2005.

System dependability is an important research issue especially if applied to critical domains. Systems are verified through tools that check the compliance of their properties with the design specifications. Formal methods provide an interesting way to study and develop verification tools thanks to their precise characterization of the modelled system. It is in this context that the presented work applies a formal method approach to system modelling and analysis.

Furthermore, test vehicles equipped with data loggers deliver important data for development, verification and validation on public roads in the United States, Europe and Dubai. Available real-world data confirms how significtmtly the Voltec propulsion concept can replace gasoline as an energy carrier by electricity. Application of electric energy from renewable sources is reducing the tank-to-wheels (TTW) greenhouse gas emissions further substantially. 

Other procedures, such as Radiation Contamination and Control procedures. Special and Reactor Special procedures, and Security procedures are provided to support operation. These are as important as operating procedures and follow similar development, verification, authorization, and implementarion requirements. 

NOTE 2 Capability Maturity Model (CMM) was developed by the Software Engineering Institute (SEI) at Carnegie Mellon University in Pittsburg, PA, USA. The SEI developed a set of best practices and an assessment method for the development, verification, and validation of complex software models. 

ANSI/ISA-84.01-1996 requires that the application software be developed in accordance with the Safety Requirements Specification (SRS). ANSI/ISA-84.00.01-2004-1 also requires this, but discusses the development of the application software with relation to the safety lifecycle. Where hardware is prone to random failures, the software is more prone to systematic failures. The safety lifecycle is important, because it is the primary mechanism for reducing systematic failure. The inclusion of the lifecycle discussion in the software section does result in repetition of the design process described in ANSI/ISA-84.00.01-2004-1 Clause 11. This repetition is intended to highlight the importance of the lifecycle in the development, verification and validation of application software. ISA-TR84.00.04-1 Annex O provides a discussion of the evolution of application software development. 

Any intervention in the automatic logic by the operators during the accident situation is permitted only as a result of EOF instructions, which have been appropriately justified during the development, verification and validation of the EOFs. ...

The guidance relates primarily to the software nsed in computer based systems important to safety. Guidance on the other aspects of computer based systems, such as those concerned with the design of the computer based system itself and its hardware, is limited to the issues raised by the development, verification and validation of software. 

By using a semi-formal approach, we could derive relevant requirements for our safety goals. The results are promising, approximately one third of the annotated requirements were involved in the call trace of the critical scenario. This has a significant impact on the development/verification effort. 

Introduction to the Safecomp 2014 Workshop DEvelopment, Verification and VAlidation of cRiTical Systems (DEWARTS T4)... 

We are grateful to the SAFECOMP organization committee and collaborators for their precious help in handling all the issues related to the workshop. We also thank all the authors of the submitted papers who manifested their interest in the workshop. With their participation the First SAFECOMP Workshop on Development, Verification and Validation of Critical Systems provides an excellent venue for cooperation and discussion for the experts in this field. Special thanks are finally due to Program Committee members and additional reviewers for the high quality and objective reviews they provided.
