Human Performance in Vessel Passages Based on Improved TOPSIS Method

To deal with the lack of design basis of passages during the initial vessel design, an evaluation index system of accessibility that is based on human factors engineering was built according to the feature of interaction between passage design and crew operation. An improved TOPSIS method was proposed by combining TOPSIS (technique for order preference by similarity to ideal solution) and grey relational method. Then, a human performance evaluation method was presented on the basis of accessibility and space resource. The changes of human performance of two single-passage alternatives and two double-passage alternatives with different crew numbers (100, 150, and 200 persons) were analyzed after the calculation of accessibility of four alternatives. The results show that when the crew number rises from 150 to 200 persons, the human performance of the single-passage alternative declines obviously, but the double-passage alternative begins to show its superiority. To optimize the accessibility and utilization of space resource for a high human performance, the passages design should be simulated and evaluated based on crew numbers.
