The problem of Supply Chain (SC) bottleneck badly influences the whole value of the SC system. Bottleneck dilatation method and dypass method can only control SC bottleneck when it has come into being. Therefore these two methods cannot solve the problem radically. As an ideal method transformed from the traditional structure of SC, Supply and Demand Network with multi-functional and opening characteristics for enterprise (SDN) is discussed, which can reduce the rate of SC bottleneck question emergence from... The problem of Supply Chain (SC) bottleneck badly influences the whole value of the SC system. Bottleneck dilatation method and dypass method can only control SC bottleneck when it has come into being. Therefore these two methods cannot solve the problem radically. As an ideal method transformed from the traditional structure of SC, Supply and Demand Network with multi-functional and opening characteristics for enterprise (SDN) is discussed, which can reduce the rate of SC bottleneck question emergence from its origin. 任何系统中都存在制约其发展的约束因素 ,供应链中的瓶颈问题则严重影响其系统的整体产出价值。消减供应链瓶颈的瓶颈舒张法和侧路消减法属于事后控制措施 ,虽然具有一定成效 ,但仍无法从根本上解决瓶颈问题。理想的方法是对供应链进行结构和功能上的改造 ,使其转变成多功能开放型企业供需网 ,从而从源头上降低系统产生瓶颈的几率。 Teamwork is a common means of cooperation in the knowledge-related work.But problems also exist in team cooperation,such as how to decide each member' s optimal effort level,how to allot the rewards and how to provide help among members,which will often directly or indirectly affect a team's overall output.Extending the optimal principle arrangement model,this article predicts that members' helping each other will improve team performance and also ascertains the optimal allotment proportion and the relationship... Teamwork is a common means of cooperation in the knowledge-related work.But problems also exist in team cooperation,such as how to decide each member' s optimal effort level,how to allot the rewards and how to provide help among members,which will often directly or indirectly affect a team's overall output.Extending the optimal principle arrangement model,this article predicts that members' helping each other will improve team performance and also ascertains the optimal allotment proportion and the relationship among each member' s importance and the amount of help and to whom such help is provided.Finally,the article discusses the way to realize a team's pareto optimal. 团队工作是知识工作中一种常见的合作方式,但团队工作中存在着如何确定成员的最优努力水平,成果分配比例以及如何提供帮助等问题,这些问题往往会直接或间接地影响团队的整体产出。本文以最优委托权安排模型为基础,对该模型进行扩展,得出成员间互相提供帮助将提高团队产出,并且确定了在此情况下各成员的最优分配比例以及提供帮助的对象和数量与成员重要性之间的关系,最后讨论了团队实现pareto方法。 Electronic marketplace and partner selection of supply chain are two different notions. Appropriate partners of supply chain drastically affect the output value of the system of supply chain. Internet-driven electronic marketplace (IEMP) can provide an effective platform to select the right partners. Through suitable classification of IEMP, and detailed analysis on the effect of IEMP for partner selection of supply chain, a model of procurement strategies for project, as well as the vital factors leading to...
