Abstract: For reflecting the uncertain in the product conceptual alternatives development based on the sensor of unmanned aerial vehicles,a technology based on multi-granular hesitant fuzzy linguistic and cumulative prospect theory was proposed.The developers used their preference hesitant fuzzy linguistic sets to express the relative importance of customer requirements,and the relative importance ratings of each customer requirement were determined based onmultiple attribute decision making model,thus the product conceptual alternatives could be developed.Secondly,the idea of cumulative prospect theory was introduced to analyze the cost,loss scene and profit scene of each alternative,and the cost perceived values,the loss perceived values and the profit perceived values could be calculated.Thirdly,the best product conceptual alternativecould be determined according to comprehensive values of each alternative.Finally,the sensor of unmanned aerial vehicles was taken as an example to prove the feasibility of the development technology.

Key words: unmanned aerial vehicles, sensor, product conceptual alternative, multi-granularity hesitant fuzzy linguistic, cumulative prospect theory
