本文从产业内贸易理论的产生和发展出发,从供给和需求两方面分析了产业内贸易理论对于我国这样的发展中国家的适用性,并且分析了以产业内贸易指标作为发展中国家工业化水平标志的局限性。

博物馆展览团队的优化组合——以成都第21届国际木偶节《偶·影·戏皮影木偶特展》为例

博物馆展览工作团队的建设,是一个庞大的工程,是博物馆人应该思考和努力的方向。以成都第21届国际木偶节《偶·影·戏皮影木偶特展》为例,从展览的文案策划、陈列设计、安全工作及团队任务分配的交叉转换等方面来探讨博物馆展览团队在人员知识结构、年龄阅历等方面的优化组合。

An improved cross entropy algorithm for steelmaking-continuous casting production scheduling with complicated technological routes

In order to increase productivity and reduce energy consumption of steelmaking-continuous casting(SCC) production process, especially with complicated technological routes, the cross entropy(CE) method was adopted to optimize the SCC production scheduling(SCCPS) problem. Based on the CE method, a matrix encoding scheme was proposed and a backward decoding method was used to generate a reasonable schedule. To describe the distribution of the solution space, a probability distribution model was built and used to generate individuals. In addition, the probability updating mechanism of the probability distribution model was proposed which helps to find the optimal individual gradually. Because of the poor stability and premature convergence of the standard cross entropy(SCE) algorithm, the improved cross entropy(ICE) algorithm was proposed with the following improvements: individual generation mechanism combined with heuristic rules, retention mechanism of the optimal individual, local search mechanism and dynamic parameters of the algorithm. Simulation experiments validate that the CE method is effective in solving the SCCPS problem with complicated technological routes and the ICE algorithm proposed has superior performance to the SCE algorithm and the genetic algorithm(GA).

合体——合心——合力——我对思想政治工作的一种参与和思考

我作为一名行政领导干部——兖矿集团唐村实业公司副总经理,在公司主要分管企业改革、企业管理及企业后勤服务工作。多年来的工作实践使我深深体会到:无论是企业的改革、经营管理或其它各项工作要顺利地完成任务就离不开思想政治工作。略举几例。 实例一:推动企业改革必须有思想政治工作做保证。近几年我们企业改革的力度是大的,企业从“工厂制”的唐村煤矿改革为“公司制”的唐村实业公司,而且是由职工参股30％的多元投资的有限责任公司。
