Machine breakdowns have been recognised in flexible manufacturing systems (FMS) as the most undesirable characteristic adversely affecting the overall efficiency. In order to ameliorate product quality and productivity of FMS, it is necessary to analyse, as well as to minimise the effect of breakdowns on the objective measures of various decision problems. This paper addresses the machine loading problem of FMS with a view to maximise the throughput and minimise the system unbalance and makespan. Moreover, insufficient work has been done in the domain of machine loading problem that considers effect of breakdowns. This motivation resulted in a potential model in this paper that minimises the effect of breakdowns so that profitability can be augmented. The present work employs an on-line machine monitoring scheme and an off-line machine monitoring scheme in conjunction with reloading of part types to cope with the breakdowns. The proposed model bears similarity with the dynamic environment of FMS, hence, termed as the dynamic machine loading problem. Furthermore, to examine the effectiveness of the proposed model, results for throughput, system unbalance and makespan on different dataset from previous literature has been investigated with application of intelligence techniques such as genetic algorithms (GA), simulated annealing (SA) and artificial immune systems (AIS). The results incurred under breakdowns validate the robustness of the developed model for dynamic ambient of FMS. 相似文献

In the field of natural language processing (NLP), the advancement of neural machine translation has paved the way for cross-lingual research. Yet, most studies in NLP have evaluated the proposed language models on well-refined datasets. We investigate whether a machine translation approach is suitable for multilingual analysis of unrefined datasets, particularly, chat messages in Twitch. In order to address it, we collected the dataset, which included 7,066,854 and 3,365,569 chat messages from English and Korean streams, respectively. We employed several machine learning classifiers and neural networks with two different types of embedding: word-sequence embedding and the final layer of a pre-trained language model. The results of the employed models indicate that the accuracy difference between English, and English to Korean was relatively high, ranging from 3% to 12%. For Korean data (Korean, and Korean to English), it ranged from 0% to 2%. Therefore, the results imply that translation from a low-resource language (e.g., Korean) into a high-resource language (e.g., English) shows higher performance, in contrast to vice versa. Several implications and limitations of the presented results are also discussed. For instance, we suggest the feasibility of translation from resource-poor languages for using the tools of resource-rich languages in further analysis. 相似文献

The majority of machine scheduling literature assumes that machines are available at all times. However, this assumption is inappropriate in certain real world situations. This study addresses the single machine and parallel machine scheduling problems, where machines are flexibly maintained and total tardiness is used as a performance measure. Machine M k should be scheduled for maintenance for a constant time, w k . It is assumed that the maintenance period [u k , v k ] is set in advance and that the maintenance time, w k , does not exceed the maintenance period (i.e., w k ≤v k ?u k ). The time u k (v k ) is the earliest (or latest) time at which machine M k starts (or stops) its maintenance. Two cases, resumable and unresumable, are considered in the single machine and parallel machine problems. Eight mixed binary integer programming models are developed to derive the optimal schedule for the problem, and size complexity and computer solution times are provided to demonstrate the models' efficiency. 相似文献

针对基于短语的统计机器翻译(SMT)模型中由于采用精确匹配策略导致的短语稀疏问题,提出了一种基于短语相似度的统计机器翻译模型.该模型将基于实例的翻译方法引入到统计机器翻译中.翻译时,对于训练语料库中未出现过的短语,通过计算源语言短语之间的相似度,采用模糊匹配策略从短语表中查找相似的实例短语,并根据实例短语为其构造翻译.与精确匹配策略相比,利用相似度进行模糊匹配增加了对短语表的利用程度,缓解了短语稀疏问题.实验表明,该模型能够明显地提高统计机器翻译的质量,效果超过了当前最好的短语系统"摩西(Moses)". 相似文献

The conventional Close circuit television (CCTV) cameras-based surveillance and control systems require human resource supervision. Almost all the criminal activities take place using weapons mostly a handheld gun, revolver, pistol, swords etc. Therefore, automatic weapons detection is a vital requirement now a day. The current research is concerned about the real-time detection of weapons for the surveillance cameras with an implementation of weapon detection using Efficient–Net. Real time datasets, from local surveillance department's test sessions are used for model training and testing. Datasets consist of local environment images and videos from different type and resolution cameras that minimize the idealism. This research also contributes in the making of Efficient-Net that is experimented and results in a positive dimension. The results are also been represented in graphs and in calculations for the representation of results during training and results after training are also shown to represent our research contribution. Efficient-Net algorithm gives better results than existing algorithms. By using Efficient-Net algorithms the accuracy achieved 98.12% when epochs increase as compared to other algorithms. 相似文献
