China is one of the most earthquake-prone countries in the world.In resentyears,the losses of lives and property caused by earthquake are disastrous. Earthquakeemergency rescue equipment is the lifeblood and material basis of the earthquakerelief work.So it is an important task to optimize the number of the earthquake rescueequipment and establish a scientific and reasonable comprehensive evaluation systemto evaluate the target.In this thesis,the earthquake emergency rescue equipment isdivided into two parts to launch the research—the conventional earthquake rescueequipment and the special rescue robots.Firstly,multi-objective planning theory is introduced into the field ofpost-earthquake relief.Illustrated by the example of rescue equipment of the heavyearthquake rescue team, a multi-objective mathematical model is constructed.Theconstraint conditions are selected by coordinating the practical significance ofoptimization goals. Then related functions of the Matlab optimization toolbox areused to solve the model and the calculation result is compared with previousexperience. The result shows that the optimization results meet the practical rescue.Developing of earthquake special robots in our country is still in the exploratorystage.It is greatly significant for design and maintenance of the equipment to conducta comprehensive assessment of it. In this thesis,take the “wheel-track seismicexploration robot”and“auxiliary rescue robot” as the object of the research, pervasiveindicator systems are designed. And take the “wheel-track seismic explorationrobot”for example, the evaluation criteria of qualitative and quantitative indicators isconstructed,meanwhile,test standards of the indicators are constituted.Then,a model of AHP-fuzzy comprehensive evaluation is designed.The detaileddescription for the steps of using method of analytic hierarchy process to comfirm theindicator weight and fuzzy comprehensive evaluation is proposed.Thirdly,based on the case of a new type of wheel-track seismic exploration robotwith a variety of sports gesture,the indicator weights are calculated.In succession, thestatistical and testing data is collected and then a comprehensive evaluation isobtained with the model of AHP-fuzzy comprehensive evaluation. By the method ofweighted average, the synthetical performance score of the robot is calculated. Finally,the evaluation results are discussed,including the analysis of the relativeimportance of the various indicators and the results of fuzzy comprehensiveevaluation.The overall situation of the robot is pointed out and a theoretical basis isprovided for further development and improment of the robot.
