Workflows are increasingly used in scientific disciplines for modelling, enacting and sharing in silico experiments. However, the reuse of an existing workflow is frequently hampered by the volatility of its constituent service operations. To deal with this issue, we propose in this paper a set of criteria for characterising service replaceability using which substitute operations can be automatically located for replacing unavailable ones in workflows.
