Latest trends in hardware and software design run contrary to the drive toward response time predictability of safety-critical systems. As a result, sound methods and tools are increasingly important for precise and reliable verification. This article introduces this problem by matching classic control theory concepts to typical marine automated processes with the goal of clarifying the notion of response time in the context of onboard digital control. It also attempts to explore the design space of integrated marine automation by using a select number of design choices that affect the response time of such systems as a starting point for further discussion. The paper concludes with an introduction of the combined solutions provided under the ABS traditional design review and the services of the Data Management and Analytics Team for the required Response Time Analysis studies.
