Bringing to bear the algorithm based on artificial life, this present paper makes an analysis on the dynamic action of the whole environment according to the emerging assembly of the artificial life arising in the home range. Zoology food chain is also an existent phenomenon both important and widely. The present paper advances an artificial life algorithm provided with food chain modality, via defining the rule by which all levels artificial life is in local action, which is distinguished as food chain algorithm. When the food chain algorithm is applied to the problem solving of the site-selection—distribution in the distribution network in supply chain management to optimize the designed distribution network and minimize the supply chain cost, this present algorithm acquires a better solution, which can be used as a reference in enterprise’s distribution network design and also as optimization problem in materials circulation and electronic commerce. At the same time, uncertain factors in supply chain needs adequately considering in practical application, that is the urban quantity demand is considered as dynamical variable to establish uncertain distribution model based on the supply chain so as to be able to supply enterprises with a set of information demanded according to the dynamic variation in the market for them to decide their theory and methods for the dynamic optimized business strategy. 原文不够流畅，斗胆做了一些修改（括号中是添加的词语，修改的标点没有标出），不知道是否符合作者的意图，附录于下： 本文运用基于人工生命的算法，根据人工生命在活动范围会出现的突现集群，对整个环境进行动态作用（分析）。生态食物链也是生态系统中重要而又有广泛存在的现象。（本文）通过定义各级人工生命的局部活动规则，提出一种具有食物链形式的人工生命算法，并称之为食物链算法。（如果）把食物链算法应用于供应链管理中分销网络的选址—分配问题的求解（以）优化设计分销网络结构并最小化供应链成本，该算法取得了较好的解，（该解）可以作为企业分销网络设计的参考，也可应用于物流、电子商务中的优化问题。同时，在实际应用中，需要充分考虑供应链中的不确定因素，把销售城市的需求量看作是动态的变量，建立基于供应链的不确定性的分销模型，为企业提供一套根据市场动态变化的需求信息做出动态优化经营策略的理论和方法。
