In the workload control literature, the Load-Oriented Order Release (LOOR) approach has been neglected since its robustness was questioned at the end of the 1990s. This paper revisits LOOR and evaluates whether its performance can be improved in two ways. First, an intermediate pull release mechanism is added to avoid starvation between periodic release events. This mechanism was recently shown to be effective at improving the performance of a state-of-the-art release method known as LUMS COR. Second, an integer linear programming model is used to manage the trade-off between the timing and load balancing functions of order release. The two refinements are assessed using simulations of different shop configurations, which allow us to evaluate robustness. Results demonstrate that the refinements contribute to improving the performance of LOOR such that it can even outperform LUMS COR. Perhaps counter-intuitively, putting more emphasis on load balancing than on the urgency of individual orders is shown to lead to a lower percentage of tardy orders. Overall, the improvements mean that concerns about LOOR’s robustness are no longer valid – it now appears suitable for a wide range of shops found in practice. 相似文献

在意义增值和意义消失同时进行也即所谓的"能指的狂欢"时代,人们对女性主义的发展给予了更多的乐观。文章以"网络红人"现象为突破口,提出"能指的狂欢"并不能带来女性更多的解放,甚至会倒退,网络时代的女性拥有了更多的自由,但并不能改变男性主掌的"话语权"。而任由自恋、价值虚无和性开放泛滥也不会给女性带来尊严与价值,而是离女性主义者最初的理想更加遥远。 相似文献

Affiliation network is one kind of two-mode social network with two different sets of nodes (namely, a set of actors and a set of social events) and edges representing the affiliation of the actors with the social events. Although a number of statistical models are proposed to analyze affiliation networks, the asymptotic behaviors of the estimator are still unknown or have not been properly explored. In this article, we study an affiliation model with the degree sequence as the exclusively natural sufficient statistic in the exponential family distributions. We establish the uniform consistency and asymptotic normality of the maximum likelihood estimator when the numbers of actors and events both go to infinity. Simulation studies and a real data example demonstrate our theoretical results. 相似文献

After the Asian Financial Crisis, the government of Hong Kong embraced the model of work-integration social enterprise (WISE) to sustain its facilitative and productivist welfare regime. Using the WISE of Pro-Love for marginalized women as a case study, the article examines the meaning of employment and social disadvantage in the organization. The ethnographic data reveal that while the WISE encourages women to participate in the paid labor market, it constructs employment in the social enterprise as part-time jobs for supplementary family income, restricts the extension of social networks for the female workers, and reinforces the cultural stereotypes of marginalized women. The study reflects on the mechanisms of the project of WISE in the welfare contexts of Hong Kong, and argues that programs targeted at labor participation cannot be automatically translated into reduction of exclusion in other domains. Long-term planning, policy coordination, and social advocacy are necessary to achieve social integration. 相似文献

The change-point detection problem is determining whether a change has taken place. Two non parametric methods based on empirical likelihood and the likelihood ratio are proposed for detecting a change-point problem in distributions for independent observations. Numerical studies are carried out to evaluate the performance of the proposed methods. The simulation results demonstrate that the proposed methods are robust, that is, they perform well regardless of whether the observations are from the same distribution family. 相似文献

通过影视作品揭示日本幼儿健康教育中健康行为方面的特点,使用内容分析法对一部日本儿童影片中幼儿健康行为进行取样并编码,并使用SPSS16.0进行数据的处理。日本幼儿健康行为中积极行为(76.69%)、指向他人行为(57.14%)、心理健康行为(48.50%)与安全生活行为(35.71%)等发生频率较高;日常健康行为、饮食健康行为、安全生活行为、身体锻炼行为、心理健康行为、关于身体疾病行为等六个方面的成绩差异具有统计学意义(P<0.01);日本幼儿健康行为成绩的性别差异具有统计学意义((P<0.001))。中日幼儿健康行为存在一定的文化差异,日本幼儿健康教育某些内容值得学习与借鉴。 相似文献
