摘要

本研究采用了一种通用的方法来描述和分析需求供应网络，即从公司的供应商到客户的网络。对于一个产品，可能有许多不同物流成本的需求供应网络。因此，我们引入了一种基于Petri网的形式，以及一种基于可达性分析的算法来找到用户指定产品结构的最优需求供应网络。该方法已经实施，目前在生产中使用的所有诺基亚业务集团。它用于网元和手机的需求供应规划。最后给出了该方法在具体诺基亚产品中的应用实例。

Supporting Demand Supply Network Optimization with Petri Nets

The present study implements a generic methodology for describing and analyzing demand supply networks, that is, networks from a companyâ€™s suppliers to its customers. There can be many possible demand supply networks with different logistics costs for a product. Therefore, we introduce a Petri Net-based formalism, and a reachability analysis based algorithm that finds the optimum demand supply network for a user-specified product structure. The method has been implemented and is currently in production use inside all Nokia business groups. It is used in demand supply planning of both network elements and handsets. An example of the methodâ€™s application to a concrete Nokia product is included.
