Use of COTS Software Components in Safety-Critical Applications – A Defensible Approach*
Current methods for the evaluation and selection of a Commercial-Off-The-Shelf (COTS) software component fail to address emergent system safety properties. This can lead to extreme difficulties in the certification of COTS-based safety-critical system development projects. In this paper, we propose a defensible approach to supporting successful use (i.e. evaluation & selection, integration, cer...
متن کاملSafety Assurance of Commercial-Off-The-Shelf Software
Commercial-Off-The-Shelf (COTS) software is increasingly being suggested for use in systems development, for reasons including cost, functionality, useability, testedness, availability of support and upgrades. At the same time, standards for use of software in safetyrelated systems are becoming increasingly stringent. This paper examines the issue of providing safety assurance for systems invol...

Electronic devices in space applications may be Radiation Tolerant or Commercial off-the Shelf (COTS). Due to cost and unavailability in many applications, the latter is usually used. In applications such as spatial ones, the COTS equipment lacks reliability against threats like heavy ion radiation therefore, some alternatives should be considered to make the equipment resistant against the pro...
متن کاملReliability Analysis of COTS-based Software System
With more emphasis on reuse of software applications, the commercial-off-the-shelf (COTS) based software systems have emerged. As a result, reliability analysis of COTS-based software system has gained prominence. The focus of this paper is to provide an overview for the state of the art of COTS-based software system reliability analysis. In this paper, we first describe the definition of COTS ...
متن کاملCOTS Product Selection for Safety-Critical Systems
There is an increasing interest in acquiring commercial-off-the-shelf (COTS) functionality for safety-critical applications. However, the selection of COTS products for such applications is still carried out in an ad hoc manner. This creates great difficulties for realistic cost and effort estimation, integration of the selected COTS product, and the certification of final COTS-based safetycrit...
