Traffic congestion in metropolitan area such as Great Tunis, has become more and more serious. Over the past decades, research in this area has grown and become an ever-increasing problem. Many academic research and public authorities' efforts have been made to alleviate this issue. In this paper, we investigate the application of neural network time series model to predict hourly traffic volumes for a Tunisian national highway (N8). A total 1-year of traffic volume data of 14 stations in both directions, where used in this analysis. The study applies Artificial Neural Network (ANN) for short term forecasting of traffic flow using past traffic data. The model incorporates traffic volume as input variable. The simulation experimental results show that the model is with good stability and the mean square is used as evaluation criteria.
在像大突尼斯这样的大都市区,交通拥堵问题已经变得越来越严重。在过去的几十年里,这一领域的研究不断发展,并成为一个日益严重的问题。许多学术研究和公共当局都在努力缓解这一问题。在本文中,我们研究了应用神经网络时间序列模型来预测突尼斯国道(N8)的每小时交通量。本分析中使用的是两个方向14个站点一年来的交通量数据。本研究将人工神经网络(ANN)应用于基于过往交通数据的短期交通流预测。该模型将交通量作为输入变量。仿真实验结果表明,该模型具有良好的稳定性,并以均方为评价标准。

These last years were marked by the ecological conscience stimulation relating to the negative effects of the human activities on the environment by the actors of stakeholders. Avowedly, to be competitive, any organization of the supply chain tends to be invested more and more in a permanent environment for a Sustainable development on all these levels by seeking not only the environmental but also social and economic aspect. In addition, the food signs are touched by this approach to ensure the harmonious and perennial of their food store. We presented in this study a new multi-criteria method for choice issues based on the main behaviors of Sustainable Development. The Sustainable Development will aim to determine the best strategy to be followed within the food store within “MONOPRIX Sfax Center”. Moreover, we must not neglect the dependency relationships that may link between the different Sustainable Development criteria. We developed a new methodology based on TOPSIS method that integrates the Choquet Integral to model the interactions between the existing criteria. This combination will result on a new TOPSISIC approach that consists of replacing the weighted sum of the TOPSIS method with the Shapley index to outline a better strategy for the food retailers.
最近几年,利益相关者的行为者对人类活动对环境的负面影响产生了生态良知的刺激。显然,为了具有竞争力,供应链上的任何组织都倾向于越来越多地投资于一个永久的环境,以实现所有这些层面上的可持续发展,不仅寻求环境方面,而且寻求社会和经济方面。此外,食品标志也被这种方法所触动,以确保他们的食品商店的和谐和长年累月。本文基于可持续发展的主要行为,提出了一种新的多准则选择问题方法。可持续发展将旨在确定“MONOPRIX Sfax中心”内食品商店应遵循的最佳策略。此外,我们绝不能忽视不同可持续发展标准之间可能存在的依赖关系。我们开发了一种基于TOPSIS方法的新方法,该方法集成了Choquet积分来模拟现有标准之间的相互作用。这种组合将产生一种新的TOPSISIC方法,该方法包括用Shapley指数取代TOPSIS方法的加权和,以概述食品零售商的更好策略。

Open Innovation (OI) has become one of the most popular concepts in Industry and Academia. Over the past decade, an outstanding body of knowledge (BOK) has been accumulated about OI and nowadays, it is one of the most reviewed topic in the field of “Innovation Management”. The concept has swiftly progressed from a restricted circle of high-tech practitioners, to a widely discussed and implemented concept in different industries. The community of researchers have made it an established research field. The primary goal of this article is to explore the concept recent developments in light of new research findings and industry best practices. Thus, we start by analyzing the model of OI, commonly contrasted to “Closed Model”, then we attempt to categorize OI and to analyze strengths and limitations of each class type. Lastly, we address the crucial issue of OI processes, we attempt to assess recent models, to discuss implementation issues and to select best practices. This paper aims to build on past and present studies to provide future directions, also, limitations are presented to point out issues that remain insufficiently documented and require further academic researches. The main theories and authors (practitioners and academics) who deal with OI have been highlighted.
开放式创新(Open Innovation, OI)已经成为工业界和学术界最流行的概念之一。在过去的十年中,关于OI积累了一个杰出的知识体系(BOK),如今它是“创新管理”领域中最受关注的话题之一。这个概念已经从一个有限的高科技从业者圈子迅速发展成为一个在不同行业广泛讨论和实施的概念。研究人员社区已经使它成为一个既定的研究领域。本文的主要目标是根据新的研究成果和行业最佳实践来探索概念的最新发展。因此,我们首先分析OI的模型(通常与“封闭模型”形成对比),然后尝试对OI进行分类,并分析每种类类型的优势和局限性。最后,我们讨论了OI过程的关键问题,我们试图评估最近的模型,讨论实现问题并选择最佳实践。本文旨在建立在过去和现在的研究,以提供未来的方向,也提出了局限性,指出的问题,仍然没有充分的文献,需要进一步的学术研究。重点介绍了治疗成骨不全的主要理论和作者(从业人员和学者)。

Emergency departments (EDs) face problems with crowding, delays, cost containment, and patient safety. To address these and other problems, EDs increasingly implement the Lean Six - Sigma approach. This approach has become a business model and a symbol of excellence, with the goal of eliminating waste and reducing defects and variations within an organization's processes. In this approach Lean is focused mainly on waste elimination, using simple and visual techniques whenever possible, and Six Sigma is focused on control and processes variability reduction, using statistical tools for this purpose. The present paper proposes a Lean Six Sigma (LSS) model supported by the DMAIC cycle with an application to the case of Habib Bourguiba's Hospital ED.
急诊科面临着拥挤、延误、成本控制和患者安全等问题。为了解决这些问题和其他问题,EDs越来越多地实施精益六西格玛方法。这种方法已经成为一种商业模式和卓越的象征,其目标是消除浪费,减少组织过程中的缺陷和变化。在这种方法中,精益主要集中在消除浪费上,尽可能使用简单和可视化的技术,而六西格玛则集中在控制和过程可变性的减少上,为此目的使用统计工具。本文提出了一个由DMAIC周期支持的精益六西格玛(LSS)模型,并应用于Habib Bourguiba医院ED的案例。

This paper describes a hybrid approach to size the hospital resources in the cases of a massive influx of victims generated by a disaster situation (natural or made man disaster). This suggested approach based on the genetic algorithm is a blending between the simulation (ARENA) and machine learning (Neural Networks). The first one produces a matrix of theoretical solutions and the second one contributes a solution based on the feedback on experiences. This method provided a reliable and efficient solution based on available resources and on a solutions applied in real cases. The result shows that the genetic algorithm provided a new solution that improves the solutions got by the simulation. Also we made an application as a decision support tool for hospital decision-makers to provide with the needs of resources in the same cases. This work is being carried out in collaboration with the Mohammed 5 hospital center in Casablanca (Morocco).
本文描述了一种混合方法,在灾害情况(自然灾害或人为灾害)造成大量受害者涌入的情况下,确定医院资源的规模。这种基于遗传算法的方法是模拟(ARENA)和机器学习(神经网络)的融合。第一种方法产生理论解决方案矩阵,第二种方法根据经验反馈提供解决方案。该方法基于现有资源和实际应用的解决方案,提供了可靠、高效的解决方案。结果表明,遗传算法提供了一种新的解,改进了仿真得到的解。我们还制作了一个应用程序,作为医院决策者在相同情况下提供资源需求的决策支持工具。这项工作是与卡萨布兰卡(摩洛哥)的穆罕默德第五医院中心合作进行的。

Dynamic dimensioning of logistics resources : Case of production workshop: Analogy with the problem of bin-packing Moroccan multinational company 物流资源的动态量纲化:以生产车间为例:与摩洛哥跨国公司装箱问题的类比
Pub Date : 2019-06-01 DOI: 10.1109/LOGISTIQUA.2019.8907270
Arias Laassiri, A. Sedqui
The present work deals with a complex topic of physical flow; it includes the dimensioning of logistics human resources in the productions lines. This involves modeling then measuring and optimizing its handling workload in order to improve physical flow. This problem can be formalized by mathematic equations, and seen as a bin packing problem; two cases are defined, the core model of bin packing with 1 dimension, and the bin packing with conflicts (incompatibilities). All of this, by applying a variety of industrial and scientific knowledge tools such as SMB, Chrono-analysis, and Bin-Packing. In order to solve the bin packing problem, we have to select simple and strong heuristics, after adapting them to our case, and validate all the constraints. Besides, we can use the sequential coupling (Heuristic - list algorithm). Finally, we will apply our method in a real industrial context.
目前的工作涉及物理流的一个复杂的主题;它包括生产线中物流人力资源的量纲化。这包括建模、测量和优化其处理工作负载,以改进物理流程。这个问题可以用数学方程形式化,可以看作是一个装箱问题;定义了两种情况,一种是一维装箱的核心模型,另一种是有冲突(不兼容)的装箱。所有这一切,通过应用各种工业和科学知识工具,如SMB、Chrono-analysis和Bin-Packing。为了解决装箱问题,我们必须选择简单而强大的启发式方法,并将其适应于我们的情况,并验证所有约束。此外,我们可以使用顺序耦合(启发式列表算法)。最后,我们将把我们的方法应用到一个真实的工业环境中。

Reverse supply chain management (RSC) enables companies to integrate sustainability in ecological, economic and social terms. Research has rarely investigated the impacts of RSC on business performance. Regarding Morocco, the literature on RSC is very rare. Most companies are not sufficiently aware of their reverse supply chain and miss out on many competitive advantages and opportunities. This article explores the current situation, using a qualitative approach through semi-structured interviews with the objective of describing the practices of the RSC, the decision-making factors that lead to the implementation of RSC and finally the impacts of the RSC on performance in the Moroccan automotive sector.
逆向供应链管理(RSC)使企业能够在生态、经济和社会方面整合可持续性。很少有研究调查RSC对企业绩效的影响。关于摩洛哥,关于RSC的文献很少。大多数公司没有充分认识到他们的逆向供应链,错过了许多竞争优势和机会。本文通过半结构化访谈,采用定性方法探讨了现状,目的是描述RSC的实践,导致RSC实施的决策因素,最后是RSC对摩洛哥汽车行业绩效的影响。

In order to make medical information fluid for health professionals and to cope with the ever-worsening complexity of care processes, information and communication technologies come to promote the coordination of health professionals, the optimization of health expenditure through a good organization of care processes and close cooperation to enable better patient care. The aim of this paper is to give a clue of the current worldwide situation of the healthcare information systems (HIS) through a Systematic literature review and how can an efficient information system improve the hospital logistics chain. Method: The authors systematically establish the research through efficient data sources in IEEE, Springer, Elsevier, Taylor and Francis, Sprouts, Google Books, we also used studies of experts of the domain from 2000 until 2018. Results: After Data synthesis, 197 studies met the inclusion criteria and we have defined three main axis of the subject which are: Implementation of healthcare information systems, methodology for evaluating Healthcare information systems, constraints and advantages related to healthcare information systems. Conclusion: Our study takes us to conclude the most relevant points that could a healthcare institution benefits from HIS. Furthermore, we find that most of the research focus on demonstrating the capabilities of HIS and how to implement a HIS, but we observed a limitation in how to evaluate a HIS and how to conduct a success of HIS in non-developed countries such as Morocco in order to improve hospital Supply chain.
为了使医疗专业人员的医疗信息更加流畅,并应对日益复杂的护理过程,信息和通信技术开始促进卫生专业人员的协调,通过良好的护理过程组织和密切合作来优化卫生支出,从而实现更好的患者护理。本文的目的是通过系统的文献综述,对全球医疗信息系统(HIS)的现状进行梳理,以及一个高效的信息系统如何改善医院物流链。方法:作者通过IEEE、b施普林格、Elsevier、Taylor and Francis、Sprouts、谷歌Books等高效数据源系统地建立了研究,并使用了2000 - 2018年该领域专家的研究成果。结果:经过数据综合,197项研究符合纳入标准,我们定义了主题的三个主轴:医疗信息系统的实施,评估医疗信息系统的方法,与医疗信息系统相关的限制和优势。结论:我们的研究让我们总结出医疗机构可以从HIS中获益的最相关的点。此外,我们发现,大多数研究都集中在展示医疗卫生系统的能力以及如何实施医疗卫生系统,但我们发现,在如何评估医疗卫生系统以及如何在摩洛哥等非发达国家成功实施医疗卫生系统以改善医院供应链方面存在局限性。
