RECOMMENDATIONS ON THE NATURE OF THE PASSENGER RESPONSE TIME DISTRIBUTION TO BE USED IN THE MSC 1033 ASSEMBLY TIME ANALYSIS BASED ON DATA DERIVED FROM SEA TRIALS

摘要

The passenger response time distributions adopted by the International Maritime Organisation (IMO) in their assessment of the assembly time for passenger ships involves two key assumptions. The first is that the response time distribution assumes the form of a uniform random distribution and the second concerns the actual range of response times. These two assumptions are core to the validity of the MO analysis but are not based on real data, being the recommendations of an IMO committee. In this paper, response time data collected from assembly trials conducted at sea on a real passenger vessel using actual passengers are presented and discussed. Unlike the IMO specified response time distributions, the data collected from these trials displays a log-normal distribution, similar to that found in land based environments. Based on this data, response time distributions for use in the IMO assembly analysis for the day and night scenarios are suggested.
