现今维修创新的困难在于创新理论过于依赖从业者个体悟性,可操作性、可培训性不强,使得常人不易获得成功.针对维修创新的困难,介绍技术创新理论,该理论源自对百万记的专利文献的收集整理、归纳提炼,否定了发明创新是灵感爆发和千百次失败的结果,发现了开发创新的町循规律.并结合维修实例说明如何使得普通维修从业人员能够创新工作. 相似文献

This paper investigates the gap between qualitative and quantitative constraints in spare parts stock control, with specific reference to warship spare parts support projects. A critical literature review of theoretical contributions about qualitative or quantitative factors for warship spare parts warehouse management is firstly provided, which allows to analyze the reasons for this qualitative-quantitative gap by addressing the limitations of spare parts models developed in the literature. Therefore a model including cloud model, marginal analysis and Lagrange multiplier method (CML) for study is proposed in this paper to bridge the gap. The model is used to solve the mix-constraints (both qualitative and quantitative constraints are considered) problem in a logic decision diagram particularly at the different decision nodes of the diagram. Finally, verifying test results show that the algorithm is feasible and its optimal support project meets the needs of engineering practices. 相似文献

基于双分布函数-浅水Lattice Boltzmann方法,建立了过饱和总溶解气体(TDG)输移模型,研究某电站下游航道整治建筑物对河道内TDG输移规律的影响。结果显示,整治建筑物的修建对主流区流态和TDG变化影响较小;航道整治建筑物对河道过饱和TDG时空分布的影响主要表征于整治建筑物局部区域范围内,整治建筑物坝田回流区流速降低,水体传质减弱,从而导致TDG浓度降低且低浓度区域面积增加,可以为鱼类提供一定避难空间。该研究为水体中TDG输移扩散的研究提供了一种新的方法,同时为改善电站泄水导致TDG过饱和对鱼类的不良影响和建设生态水道提供科学依据。 相似文献
