Software Configuration Management for Rail Transit Operations

Software Configuration Management (SCM) is essential and critical throughout the life cycle of any rail- transit system since it directly supports and assures a high-level of Hazard Management, System Safety and System Assurance. Improperly baselined, validated, verified or incorrectly configured or interfaced softwares will: (1) lead to improper hardware performance, (i.e., improper performance of components of a rail transit system); (2) result in softwares that are unable to respond to hardware failures and handle rail-transit system emergency situations; (3) not be unable to act on hazard control requirements of the hardware; and (4) be unable to detect failures resulting from software control errors. This paper describes the requirements for SCM for rail transit and methods for preparing a SCM Plan. These include the establishment of the following elements: (1) software configuration baseline; (2) configuration identification; (3) evaluating and implementing software changes and configuration control configuration status accounting; (4) configuration audits and reviews; (5) interface management; and (6) control of vendor supplied/acquired softwares.
