Abstract

Understanding tradeoffs among stakeholder requirements regarding liveness (something good happens) and safety (nothing bad happens) is crucial for designing sociotechnical systems (STSs). Safety-focused specifications restrict agents' actions to avoid undesired executions. However, such restrictions hinder liveness. We formalize such tradeoffs using the elements of an STS specification to understand how much a specification promotes liveness or safety. We propose metrics to measure liveness and safety, and demonstrate how constraint logic programming is used to compute such metrics.
