Evaluation Approaches And Application On Warship Collaborative Demonstration

The urgent need for the change of demonstration mode is produced with the development of the combat thinking and design manners.However,warship demonstration still depends on qualitative analysis from experts at present.How to use fruit of basic research,enrich warship demonstration approaches and improve demonstration means become very important on the background of warship integrated collaborative demonstration.Collaborative demonstration mode can overcome the disadvantages of traditional demonstration mode to optimize demonstration resources and share demonstration knowledge.Demonstration factors such as demonstrators,methods,software and datum are effectively managed and orderly involved by digital demonstration process.Evaluation is very important for warship demonstration.Those better alternatives chosen by comprehensive evaluation will directly become reference for management department to make decision and guideline to design warship in detail.Therefore,beginning with alternatives evaluation and considering some practical problems in warship demonstration,evaluation methods and application on warship collaborative demonstration are studied in this dissertation.The main contents of the dissertation are the following:(1)Aiming at the disadvantage of the traditional weights analysis methods,the weights analysis model based on integrated QFD is proposed and established.The model depicts the interrelationship between user requirements and evaluation criteria by a graphic style.The model is to use house of quality as computation framework,and then evaluates the user requirements importance and requirements satisfaction on the same type of equipment respectively by Kano model and multivariate connection number.The accuracy of applying QFD method into warship demonstration is improved by the provided model.Furthermore,the graphic method is clear so that the weights are traceable.(2)Aiming at much less research on comparison between different evaluation methods,stability analysis approaches based on MCS/WSI is proposed.The approaches take ordering matching rate,ordering mean-square deviation and stability intervals of weights as feature parameters to analyze the stability of evaluation method under the change of alternatives number and criteria weights.The approaches help to overcome the disadvantages of traditional qualitative analysis and acquire quantitative comparison results between different evaluation methods.(3)Aiming at the inconsistency of evaluation results in warship comprehensive evaluation,a combination evaluation model based on fuzzy borda number is established.The model uses Kendall—W correlation to check up the compatibility consistency of individual method.Then fuzzy-borda number method is used to get the comprehensive results.Finally,the model employs Spearman correlation to make sure the coherence between results from the combination evaluation and individual evaluation.By this model,the idea of combination is introduced into warship demonstration and the disadvantage of borda number method is also overcome.(4)With the case of warship power system alternatives evaluation,the provided approaches are applied to empirical study.The application results show the feasibility and effectiveness of the approaches.In addition,an approach based on sustained speed required power to analyze feasible alternatives is proposed considering the shortage of feasibility analysis method.The approach computes the required power for sustained speed by resistance superposition calculation and then compares calculation result with the total power provided by configuration alternatives.The approach overcomes the shortage of traditional qualitative method and decreases the subjective uncertainty influence of demonstrators.It provides demonstrators a new thinking to analyze feasible configuration alternatives(5)Process experiment of alternatives evaluation on warship collaborative demonstration is finished,Evaluation approaches proposed in the dissertation taken as model basis,process model and knowledge base of warship powersystem collaborative demonstration are designed in the experiment.Demonstration factors such as demonstrators,methods,software and datum are effectively integrated and orderly involved.Technology feasibility of process management and knowledge management in warship collaborative demonstration are also verified in the dissertation.
