环境资源问题日益凸显、人们环保意识的增强以及经济利益的驱动,促使社会进行废旧产品回收再利用,以发展绿色经济。拆卸作为回收再利用过程中的核心环节,采用流水线的方式组织产品精细化拆卸,可实现资源最大化价值。然而,零部件作业任务在流水线上分配排序过程复杂,各工作站上的作业负荷需保持相对均衡,才能保证拆卸线高效运行。为此,本文在拆卸线工作站数量固定的情况下,以最短节拍时间和均衡任务在工作站上的分配为目标,建立第Ⅱ类拆卸线平衡问题优化模型,并提出一种并行动态邻域深度搜索算法进行求解。所提算法采用动态搜索机制实现解在各邻域结构集内的并行深度搜索;通过设置扰动阈值对解实施干扰,以加快跳出局部最优;在节拍时间调整过程中,采用基于二分法的定界策略,以实现向最优节拍时间的快速靠拢。最后,通过不同规模算例验证了模型的有效性以及算法的高效性。  相似文献

In this study, we introduced a method for building a Bayesian nomogram and proposed an appropriate nomogram for type 2 diabetes (T2D) using data from 13,474 subjects collected from the 2013–2015 Korean National Health and Nutrition Examination Survey (KNHANES) data. We identified risk factors related to T2D, proposed a visual nomogram for T2D from a naïve Bayesian classifier model, and predicted incidence rates. Additionally, we computed confidence intervals for the influence of risk factors (attributes) and verified the proposed Bayesian nomogram using a receiver operating characteristic curve. Finally, we compared logistic regression and the Bayesian nomogram for T2D. The results of the analysis of the T2D data showed that the most influential factor among all attributes in the Bayesian nomogram was age group, and the highest risk factor for T2D incidence was cardiovascular disease. Dyslipidemia and hypertension also had significant impacts on T2D incidence while the effects of sex, smoking status, and employment status were relatively small compared to those of other variables. Using the proposed Bayesian nomogram, we can easily predict the incidence rate of T2D in an individual, and treatment plans can be established based on this information.  相似文献

Understanding of the harmfulness of game types is needed when planning harm minimization and prevention strategies. Adult data (N = 3555) from the Finnish Gambling 2015 survey was used to investigate the associations between different game types and gambling-related harms. A negative binomial regression model was used to analyse the effects of demographics, gambling involvement factors, and engaging in different game types on the number of gambling-related harms, which were evaluated by PGSI and SOGS. Age of 18–24, gambling several times a week, high relative expenditure, online gambling and engaging weekly either in scratch games, betting games or slot machine gambling were associated with a higher number of gambling harms. Chasing losses was the most typical harm among online poker players and fast-paced daily lottery game players, while poor self-control was the most typical harm with other game types, although some of the results were not statistically significant. Multiple factors were associated with gambling harms, including young age and gambling intensity. Games that provide a possibility for high-frequency gambling are more linked to harms. Recommendations should be implemented to incorporate effective harm-minimizing strategies in the regulation of specific game types both at the legislative level (provision and supply) and at the public health level.  相似文献

Functional neurological symptom disorder, alternatively termed conversion disorder (FNSD-CD) (Although the DSM-5 utilises the term 'conversion disorder', practitioners and consumers consider this to be an outdated, unsubstantiated and often stigmatising term. In accordance with this, the current terminology used in the field is 'functional neurological symptom disorder'), involves symptoms of altered voluntary motor or sensory functions without identifiable nervous system disease or pathology. It is considered a psychiatric disorder and is, thus, listed in the Diagnostic and Statistical Manual of Mental Disorders (5th Ed.; DSM-5). As per the nosology of the DSM-5, the discrete behavioural or psychological syndrome or pattern observed in FNSD-CD is assumed to be a function of a problem of, or a disorder within, the individual. Accordingly, the psychiatric approach to FNSD-CD, as set out in the DSM-5, invokes an assumption common to the medical model which is that of lineal (i.e., straight-line) causality, namely, causal events are arranged in a lineal sequence. The interactional approach, however, which is a development of general system theory in the field of family therapy, offers an alternative approach to understanding psychiatric disorders. Specifically, this approach places the emphasis on the relationships between individuals and their reciprocal influences on – including their psychological and emotional wellbeing with – one another. It draws on the assumption of nonlineal (i.e., circular) causality, namely, causal events are arranged in a circular sequence. From an interactional approach, therefore, FNSD-CD is thought to be a function of a problem of, or a deficit within, the individuals’ relationship/s, rather than within an individual, per se. This article utilises a composite case study to investigate FNSD-CD from an interactional approach.  相似文献

西方国家和文化思想内涵的演变走过了一条由对自然、社会的认识逐渐转变到对政治制度的和谐探讨的道路,实现和谐社会的途径偏重于和谐制度的设计,及其对整个社会和谐发展的影响,逐渐形成了五种和文化社会理想模式。和文化社会实践主要通过民主体制、法律体系、福利制度三方面体现。  相似文献

Experimental findings suggest limited effects for corporate social responsibility (CSR) to inoculate a company prior to a crisis. CSR may be viewed as accommodative window dressing that diminishes resources to assure corporate competence. When an accident occurs, emphasis in crisis communication on corporate ability (CA) may be more effective than CSR, especially when corporate culpability is low.  相似文献

<九歌>文体性质问题历来争议较大,学者各执一端,讫无定论.根据祭祀仪式"仪式诗歌"在文体上多表现为"混合性艺术"的一般规律,对<楚辞·九歌>文体进行新的界定,认为<九歌>为"大文体",其中包孕"小文体".而且将<九歌>认定为"混合性艺术",对深入探讨楚辞体的发展形成过程、屈原<离骚><九章>等作与<九歌>在文体上的渊源关系等重大学术命题,具有重要意义.  相似文献
