Abstract. In this paper we develop a process modeling framework for the evaluation and formal
validation of Panama Canal system operations. Component- and architecture-level processes are
organized into a three level hierarchy and modeled in LTSA. Safety and progress requirements
are formally expressed as processes that can be evaluated through compositional and search
processes, respectively.
Introduction
Problem Statement. The Panama Canal is one of the world's most important waterways.
Initially opened for operation in 1914, the canal is now in the midst of a US $5 billon upgrade
