Survey of Requirement Management Techniques for Safety Critical Systems

摘要

Safety Critical Systems (SCS) are critical in organizing requirements and that's why needs appropriate requirement engineering. Requirements that are not completely understood and defined are the primary cause for safety related problems. In order to accomplish the task of eliminating chances of mismanaged requirement engineering. We have sorted out approaches of improvised communication between Requirement Engineering (RE) and SCS in Safety Engineering. We have analyzed activities and techniques that should be performed by RE during safety analysis. Moreover, specified tools are explored that are used for analysis. We have focuses on systematic literature review for SCS where main focus is on mandatory safety concerns. Schemes are analyzed as per research questions to identify that which schemes consider these questions in three conditions including satisfactory, partial or not handled. We have selected a large number of articles from different publishers and then identified the articles with duplicate features. Finally we have selected a set of articles after eliminating duplicate ones and then evaluated these schemes as per research questions. We have concluded that requirement completeness, strong need for standard safety analysis tool and compliance with safety standards are mandatory to meet safety requirements during RE process.
