The markets in which organizations currently operate require them to use behaviour based on both exploitation strategy and exploration strategy, each of which contributes fundamental benefits for the firm’s success. Exploitation strategy attempts to obtain the maximum advantage from existing abilities, whereas exploration strategy searches for new ways for the organization to adapt. Further, since manufacturing markets are characterized by short product life, they require a high level of manufacturing flexibility, which can play a crucial role in the development of the exploitation and exploration strategies. This study analyses the relationship of manufacturing flexibility to exploitation and exploration strategies, taking into account an issue of maximum international scope: the implementation of ISO standards. In many international markets, ISO implementation is crucial in enabling organizations to be competitive. However, no consensus has been reached concerning the real benefits that these systems provide to the organizations that implement them. The main goal of our study is to analyse whether there are significant differences in the relationship of manufacturing flexibility to exploitation and exploration strategies in ISO 9001:2000 certified organizations and non-certified organizations. Our results show that most of the relationships analysed are only significant in ISO certified organizations. As an added value, the study analyses the relationship of exploitation and exploration strategies to organizational learning orientation and finds this relationship to be significant in all cases. 相似文献

We consider the exploration process associated to the continuous random tree (CRT) built using a Lévy process with no negative
jumps. This process has been studied by Duquesne, Le Gall and Le Jan. This measure-valued Markov process is a useful tool
to study CRT as well as super-Brownian motion with general branching mechanism. In this paper we prove this process is Feller,
and we compute its infinitesimal generator on exponential functionals and give the corresponding martingale.

中国紫BaCuSi2O6是中国古代人工颜料硅酸铜钡的一种,是中国古代科技史中独树一帜的文明成果,代表了当时中国的科技水平和科技成就。水热合成法通过高温高压的水蒸气使那些在大气条件下不溶或难溶的物质溶解,并且重结晶来进行无机合成与材料处理,是近年来比较新兴的方法。参考前人研究,采用水热合成法,选择BaCl2·2H2O,CuO,Na2SiO3·9H2O为原料,按照目标产物化学计量比称取,调控溶液pH、合成温度和保温时间等影响因素,制备出高纯度的中国紫。产物的物相与纯度使用XRD表征。实验结果表明,当10≤pH≤12时可生成纯度较高的中国紫,160 ℃时生成的中国紫纯度较180 ℃更高,且随着水热时间的延长,中国紫的纯度提高。考虑到绿色安全、能耗低、操作简便等因素,最终得出水热制备中国紫的最佳制备条件是pH 12,温度为160 ℃,保温时间48 h。中间产物BaSi2O5和Ba4Si6O16的发现,表明在硅酸铜钡晶体的生长过程中Ba与Si先与O以不同形式结合,Cu最后参与构筑硅酸铜钡晶体。该工作提供了一种新方法用于合成纯净中国紫,可用来做文物保护修复材料;同时在中国紫的合成机理研究方面提供依据和线索,对中国古代科技史研究具有促进作用。 相似文献

It is a powerful tool of talent development to reinforce the nation's power. For educating comprehensive talents, teaching of chemistry laboratory for undergraduate is of great significance. In the light of college chemistry experiment, we propose a teaching mode named "3 factors & 1 choice", that is teaching in accordance with majors, teaching in accordance with local condition, teaching in accordance with general trends, and optional experiments. It aims to combine the characteristics of each major with specific experiments, to enhance students' conscious activity, and to strengthen students' creative thought and practical innovation ability. 相似文献
