Establishment Of Intelligent Layout Design Method For Passenger Cabins On Large Cruise Ship

The large cruise ship is a complex and unfamiliar research object,what’s more,there are few researches on the characteristics of it at home and abroad.So to study on the layout of cabins on cruise ship,there is a need to analyze and summarize the characteristics of them.And it is difficult to carry out the research on layout of cabins on lager cruise ship for it involves various types and great number of cabins,besides,the layout methods of general ships cannot be directly applied to cruise ships.In order to simplify the issue,this paper focuses on the layout of “passenger cabins” that provides services to passengers on cruise ships,and in the process of research,knowledge engineering techniques and intelligent optimization methods are respectively introduced to solve the problems.First of all,based on the analysis of characteristics of passenger cabins from the perspective of functions,the passenger cabins can be classified into living cabins,catering cabins and entertainment cabins,of which the entertainment cabins are highly customized,so not only the cabin varied from one to another,but the layout characteristics are also ambiguous.On the other hand,the layout characteristics of the living cabins and catering cabins are relatively clear,whose layout is similar on different cruise ships.Based on the statistical analysis of the frequency of cabin locations,the layout characteristics of passenger cabins are summarized,and then the knowledge management model is applied to organize and manage the summary of experience,relevant rules,and the collected cases.With experience and rules represented in production representation,the cases are represented by the general layout drawing of deck area,in which way the process of using knowledge is simplified.Then,to figure out the layout of cabins on deck areas,the key attributes of deck area and cabin are defined.And among the attributes,it is defined for the first time that landscape value,material distribution difficulty,frequency,and the suitability of large cabin,based on which an evaluation function is established to guide the layout of catering cabins and entertainment cabins among the deck areas.Through the rule-based reasoning(RBR)technique,the layout constraint is searched from the knowledge base.With the constraint and evaluation function above,a layout model is established whose validity is verified by example.On the analysis of the model’s output,we can see that the model can effectively guide the layout of catering cabin,and shopping cabins and sports cabins which are a part of entertainment cabins.And case-based reasoning(CBR)technology is used to search the similar layout drawing in the knowledge base to provide a reference for the layout of the cabin in the deck area.Aiming at the problem of cabins layout in deck area,an improved energy method is put forward,based on which,another layout model is established,and a deck area with a pool is taken as an example to validate it.Furthermore,to realize the intelligent layout,the genetic algorithm is applied to to popularize the model and the process of population initialization in genetic algorithm is modified by game analysis method,so that it can be more adapted to the model.Finally,the interior layout of the balcony room is used as an example to verify the validity of the model for the balcony room has similar layout characteristics with the deck area,and the layout in it is compact,so that it can get a better verification.In this paper,by studying the layout methods of passenger cabins on large cruise ships,a layout model is estabilished on knowledge base to solve the problem of “arranging cabins layouts on different deck areas” and anohter model is built with an intelligent optimization algorithm to solve the problem of “the layout of different cabins within the deck area”.There is certain innovation and reference value in the research idea.
