12.2统筹图中有关参数的计算 关键路线(critical path):统筹图中从总开工事项顶点到总完工事项顶点的最长的有向路 华罗庚先生称关键路线为主要矛盾线 关键路线的长度:关键路线上各工序时间之和 关键工序:关键路线上的工序

4.1整数规划 整数规划(IP, integer programming):决策变量的全部或部分取整数值的线性规划

12.1统筹图 统筹方法是利用数学方法和网络图来研究、分析工程项目的合理组织、协调管理的一种科学管 理方法 这一方法于20世纪50年代产生于美国.956年,美国杜邦公司为协调公司不同业务部门的系 统规划,利用网络方法制订了第一套网络计划,称为关键路线法(CPM, Critical Path Method).1958年,美国海军武器局在制订“北极星”导弹研制计划时,同样利用了网络方法,但 更注重于对各项任务安排的评价和审查,称为计划评审技术(pr, Program Evaluation and Review Technique)

2.2.1树 1847年,克希霍夫在研究电网络方程时首次提出了树的概念 树(tree): connected(连通的) and acyclic(无圈的) graph. 平凡树(trivial tree):v=1的树,即K1(平凡图);非平凡树(nontrivial tree): otherwise. 叶(leaf):树的悬挂点(度为1的顶点);分支点(branch vertex:度≥2的顶点 非同构的树

2.1.1图的基本概念 (1) 图(graph):用(顶)点代表对象,顶点之间的边表示对象之间的关系 滨州 “图是关系的数学表达” 注:图和几何图形不同.几何图形描述物体

Eco514Game Theory Lecture 3: Nash Equilibrium Marciano Siniscalchi September 23, 1999 Introduction Nash equilibrium has undoubtedly proved to be the most influential idea in game theory. enabled fundamental breakthroughs in economics and the social sciences. Its development was a major intellectual achievement; what is perhaps more important, it Recent foundational research has emphasized the subtleties in the interpretation of Nash

Our research program involves the design, synthesis, and detailed physical investigation of novel molecular and nanoparticle materials which display unique self-organized hierarchical structures and specific optical, electronic, andor magnetic properties. Emphasis is placed on materials with potential applications in light-emitting devices, optical memory devices, molecular level and single particle level switching devices, and chemosensory devices

Nash equilibrium has undoubtedly proved to be the most influential idea in game theory. enabled fundamental breakthroughs in economics and the social sciences. Its development was a major intellectual achievement; what is perhaps more important, it Recent foundational research has emphasized the subtleties in the interpretation of Nash equilibrium. This lecture deals with the technical details of equilibrium analysis, but also with these interpretational issues. However, a more precise appraisal of the situation must
