摘要
市场需求预测问题具有多因素、离散、动态和并发等特点，尤其是并发性始终影响预测结果的稳定性和精度。本文利用Ｐｅｔｒｉ网良好的离散事件动态表达和计算能力以及图形表示的直观性，建立市场需求预测问题的Ｐｅｔｒｉ网模型，并对模型的动态。
Multi factors,discreteness,dynamic and concurrency are the characteristics of the market demand prediction system.Concurrency especially affects,from beginning to end,stability and precision of the predicted results.Petrinet is known for its fine description of discrete and dynamic events,Parallel computation ability,and direct graphics representation.In this paper,we adopt Petrinet to model the market demand prediction system,and analyse the dynamic and concurrent behaviors of the model.
