Abstract:Mobile crowdsourcing platform is a location-based crowdsourcing operation mode. Optimizing the task pricing strategy for mobile crowdsourcing platform can help alleviate the problem of low task accomplishment. This article establishes an initial pricing model based on location, by using back propagation neural networks. What’s more, based on the factors affecting the completion of tasks, the incentive function, the probability distribution function of task snatching and the proportion integration differentiation negative feedback network are introduced to adjust the pricing model. Eventually, a final pricing adjustment scheme is proposed. Experimental results contrast shows that the optimized task pricing model effectively reduces the task publisher's cost expenditure, while increasing members' engagement and, at the same time, guaranteeing the overall task accomplishment.
