  • The shipyard is a key facility determining the quality and performance of ships in the shipbuilding industry. A well-designed ship requires skilled shipbuilders who can deliver on parameters such as quality, timeline, budget, and environmental considerations. Evaluating shipyard performance, including shipbuilding, ship repair, and ship conversion, is crucial for strategic advancement. This thesis proposes a new performance measurement framework, the integrated Value Engineering and Risk Assessment (VENRA), to enhance shipyard performance. The framework introduces a conceptual and multi-dimensional criteria framework that considers criteria prioritisation and the evaluated shipyard conditions score. It suggests integrating five criteria groups, namely Technical, Business, External, Personnel Safety, and Environment, which include a number of criteria and sub-criteria. These criteria are intended to be used for shipyard assessment and identifying areas for improvement. In order to achieve the above framework, fuzzy Decision-Making Trial and Evaluation Laboratory (DEMATEL)-Weighting Evaluation Technique (WET) and fuzzy DEMATEL-Analytical Hierarchy Process (AHP) methods are employed. These methodologies assess the VENRA criteria by analysing interrelationships and assigning weight rankings to criteria and sub-criteria. An objective grading system is developed with fuzzy multi-attribute group decision-making (FMAGDM) approach to evaluate the shipyard’s condition score based on the VENRA criteria framework. By integrating criteria analysis and the shipyard score, a comprehensive analysis is conducted to determine the prioritisation of criteria, considering causal relationships, weight rankings, and the shipyard’s assessment score. The proposed framework has been applied and tested in case studies involving three different shipyards: a small shipyard specialising in aluminium ship production, a medium-sized shipyard focused on merchant ship production and a shipyard specialising in cruise ship production. The outcomes of this study include identifying the most influential criteria and sub-criteria, analysing shipyard performance measurements, prioritising enhancement tasks, and providing specific recommendations to improve shipyard performance.
