两台同类机排序问题SPT算法的最坏情况比

本文研究以工件总完工时间为目标函数的两台同类机排序问题, 给出了SPT算法以两台机器速度比为参数的最坏情况比, 使该算法的常数最坏情况比上界与下界的差距由0.430 5减小到0.014 7。     

不同情形下供应链优化决策模型的比较分析

本文提出三种不同情形（制造商与零售商追求各自利润最大化，并且没有价格折扣策略；制造商与零售商共同追求总利润最大化，不实施价格折扣策略；制造商与零售商共同追求总利润最大化，并实施价格折扣策略）下供应链价格和库存补充策略的优化决策模型，并通过具体数例进行比较分析，结果表明，供应链合作并实施价格折扣策略时的供应链总利润最高，而供应链双方利润分配系数的变化对基于供应链总利润最大化的供应链优化决策没有影响．     

两厂商情形下二度价格歧视的需求分段数研究

在线性需求函数条件下,对两寡头厂商实行二度价格歧视进行了静态博弈分析,以确定对需求量区间的合理分段数.研究结果表明:对需求量区间的划分原则和评价标准以及分段数目类似于垄断情形,仍以二至三段为宜.

Finite-dimensional variational inequality and nonlinear complementarity problems: A survey of theory,algorithms and applications

Over the past decade, the field of finite-dimensional variational inequality and complementarity problems has seen a rapid development in its theory of existence, uniqueness and sensitivity of solution(s), in the theory of algorithms, and in the application of these techniques to transportation planning, regional science, socio-economic analysis, energy modeling, and game theory. This paper provides a state-of-the-art review of these developments as well as a summary of some open research topics in this growing field.The research of this author was supported by the National Science Foundation Presidential Young Investigator Award ECE-8552773 and by the AT&T Program in Telecommunications Technology at the University of Pennsylvania.The research of this author was supported by the National Science Foundation under grant ECS-8644098.     

An exact solution procedure for multi-item two-echelon spare parts inventory control problem with batch ordering in the central warehouse

We consider a multi-item two-echelon inventory system in which the central warehouse operates under a (Q,R) policy, and the local warehouses implement basestock policy. An exact solution procedure is proposed to find the inventory control policy parameters that minimize the system-wide inventory holding and fixed ordering cost subject to an aggregate mean response time constraint at each facility.     

城镇土地分等估价法析议及应用

本文在分析测算城镇内部基准地价方法的基础上，提出一种测算城镇之间基准地价水平的方法──分等估价法。此方法从宏观上调控城镇之间的地价水平，迅速建立一个大城市和所属县市城镇的基准地价体系，对目前正在全国范围内开展的城镇土地评估工作具有较好的实践意义和应用参考价值。并应用此方法建立了宁波市各城镇基准地价体系。     

Massively parallel computation of large-scale spatial price equilibrium models with discriminatory ad valorem tariffs

In this paper, we develop a perfectly competitive spatial equilibrium model in price and quantity variables in the presence of discriminatory ad valorem tariffs, a widely used trade policy instrument. We derive the equilibrium conditions and formulate them as a variational inequality problem. An algorithm is then proposed for the computation of the equilibrium pattern and convergence results established. The algorithm resolves the problem into very simple subproblems, each of which can be solved simultaneously and in closed form. Finally, the algorithm is implemented on the massively parallel Thinking Machines CM-2 and CM-5 architectures, known as the Connection Machines, and numerical results presented.

粮食价格补贴政策的理论分析

本文利用经济学原理对我国政府采取的粮食价格补贴政策进行了理论分析和评价，说明这一政策能改变粮食市场需求曲线的弹性，减小粮食价格的波动，提高粮食产量。尽管这一政策会增大社会成本，但总的来说利大于弊，对人口众多的我国来讲尤其具有战略意义。
