对群智感知任务类型中的突发任务资源分配问题进行研究。首先分析突发任务的特点,建立突发任务需求不确定的多阶段随机规划模型,并使用三个指标:效率、效力和公平来衡量资源的分配,提出以最小化成本为目标的非线性优化问题。然后,针对优化问题,提出基于Q学习算法的资源分配方法,并与动态规划算法和启发式算法作对比。实验结果表明,Q学习算法在精度上优于启发式算法,在计算速度上优于动态规划算法。
A Resource Allocation Method for Task with Demand Uncertainty in Crowd Sensing
The problem of resource allocation for sudden tasks in crowd sensing has been studied.Firstly,the characteristics of sudden tasks are analyzed and a multi-period stochastic programming model with uncertain demand for sudden tasks is estab-lished.Three indicators are used to measure the allocation of resources,which are efficiency,effectiveness and fairness.A nonlin-ear optimization problem for minimizing cost is proposed.Then,aiming at the optimization problem,a resource allocation method based on Q learning algorithm has put forward and compare with dynamic programming algorithm and heuristic algorithm.Experi-mental results show that Q learning algorithm is better than heuristic algorithm in accuracy and dynamic programming algorithm in computing speed.
