Ship manufacturability is one of the most important works for modern shipbuilding industry. The basic concept of ship manufacturability and its evaluation system are discussed first. Then the characteristics of ship manufacturability are analyzed. One kind of ship manufacturability evaluation (SME) strategy is put forward. Two evaluation methods of ship manufacturability (knowledge-based manufacturability evaluation and simulation-based manufacturability evaluation) are proposed too. With the proposed methods, the ship manufacturability can be evaluated reasonably.
