Embodiment Construction

[0018] Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0019] When this ship performance evaluation method is implemented, a benchmark ship type is first set, and several sample ship types are dynamically selected according to the benchmark ship type. The previous generation ship type is the main one. For each ship type, there is only one reference ship type and it remains unchanged for a certain period of time, so that a fixed relationship is formed between the evaluation ship type and the reference ship type, so that the evaluation results are quite credible and comparable.

[0020] Then, the ship performance evaluation index is divided into five evaluation items: performance advancement, construction economy, operation economy, ship type adaptability and configuration advancement, and then each evaluation item is further decomposed into different groups, and each group is set Grouping can be ...

Abstract

The invention discloses a ship performance evaluation method, which not only adopts direct parameter comparison and relative coefficient comparison, but also carries out comprehensive evaluation on the main performance of the ship by an innovative subjective evaluation method from five different angles of performance advance property, construction economy, operation economy, ship form applicability and arrangement advance property, and can simultaneously evaluate the comprehensive economic technology indexes of the ship from the angles of ship construction party (shipyard) and user party (shipowner). Therefore, the evaluation method is more comprehensive and objective in the ship performance evaluation, has comparability and traceability of credibility in the evaluation result, has popularization and application value in ship industries in China, and is expected to have certain theoretical significance and engineering practical application value in ship design scheme argumentation, ship form optimization, ship scientific research achievement evaluation and the like in China.

Description

technical field [0001] The invention relates to a method for evaluating the performance of a ship, in particular to a multi-angle evaluation method for the performance of a marine transport ship. Background technique [0002] Since the beginning of its entry into the international ship market, the Chinese shipbuilding industry has always regarded the advanced ship products of Japanese and Korean shipyards as its goal of catching up. However, how to evaluate the main performance level of ship products from a quantitative and objective perspective has always been the focus of the Chinese shipbuilding industry. subject. [0003] At present, in the evaluation of ships, a benchmark ship type is generally set according to the ship type, and then several comparison ship types (sample ship types) are dynamically selected. In principle, ships built by shipyards in Japan and South Korea with relatively advanced performance are selected as the benchmark ship type. For each ship type, ...
