Computer simulation and analysis framework for floating caisson construction operations

• A floating caisson fabrication simulation platform (CaissonSim) is developed.
• A valid methodological framework for statistical analysis is founded.
• Critical production parameters are analyzed for sensitivity.
• The slipforming activity is the key driver of the whole production process.
• CaissonSim is a practical tool modeling the stochastic nature of activities.

The aim of the research is twofold; the development and implementation of a floating caisson fabrication process simulation platform (CaissonSim) which will also cater for statistical analyses and the founding of a methodological framework investigating system response variations. A general purpose simulation language (Stroboscope) was used for modeling and the analysis took into consideration variables such as resource deployment strategies, task execution sequence and physical parameters. Following a brief presentation of CaissonSim development process and main components, a real large-scale infrastructure project is examined to ensure the system's applicability and usefulness. In addition, critical production parameters are analyzed for sensitivity. The slipforming activity is the key driver of the whole production process, a fact which may be elusive by using different approaches to the problem. As such, CaissonSim is a practical tool of use to both academics and practitioners in analyzing floating caisson fabrication activities.
