In this work, we study the evolution of the noise generated by a great road in the agglomeration of Sousse and its impact on an urban in vicinity. The objective is to develop a reliable strategic noise map to quantify the sound levels produced by the road and to compare them with the regulatory limits. To do this, we make use of the method NMPB- noise prediction to estimate the nuisances emitted by such traffic. The results show that the residents are exposed to significant noise power levels and a confinement caused by building amplifies it. These high noise levels can threat the quality of the environment and to impact the health of citizens.
在这项工作中,我们研究了苏斯城市群中一条主干道产生的噪音的演变及其对附近城市的影响。目标是制定一个可靠的战略噪音地图,量化道路产生的声音水平,并将其与监管限制进行比较。为了做到这一点,我们使用NMPB-噪声预测方法来估计这种交通所发出的滋扰。结果表明,居民暴露在显著的噪声功率水平,而建筑造成的限制放大了它。这些高噪音水平会威胁环境质量,并影响公民的健康。

We investigate in this paper a cooperative schema for the ordering problem in a two-level Supply Chain involving two suppliers and multiple retailers. Each supplier aims to maximize its product sales by offering attractive quantity discounts; and conversely, the retailers aim to minimize their supply costs through coalition's formation in order to benefit from these discounts. To tackle this ordering problem, we propose a game theory-based model and a solution approach that leads to an equilibrium state in the cooperation process by forming coalitions. The exact method proposed to solve the problem provides stable coalitions of retailers helping them minimizing their supply costs. An illustrative example and preliminary experiments are provided to show the applicability and usefulness of the approach.
本文研究了一个涉及两个供应商和多个零售商的两级供应链订货问题的合作模式。每个供应商的目标是通过提供有吸引力的数量折扣来最大化其产品销售;相反,零售商的目标是通过联盟的形成来最小化他们的供应成本,从而从这些折扣中获益。为了解决这一排序问题,我们提出了一个基于博弈论的模型和解决方法,该模型和解决方法通过形成联盟在合作过程中导致均衡状态。解决这个问题的确切方法是提供稳定的零售商联盟,帮助他们最小化他们的供应成本。最后给出了一个实例和初步实验,证明了该方法的适用性和有效性。

Environmental impact of any kind of business activity is one of the major issues according to the green logistics concept. The global logistics tends to reduce pollution and energy consumption in the purpose of saving natural resources for future generations and optimize different kinds of activities to achieve this goal. In this paper we analyse the energy market in Poland with the aim to present the energy indicators and their evolution during years, what allows for generalized interference within the scope of green logistics. According to the conclusions from forecasting and analytic works presented in the document "Polityka energetyczna Polski do 2030 r." [The energy policy in Poland until 2030], it is assumed that the national consumption of electric energy will increase by 80-93 %. Thus, it is assumed that the society's dependence on the electric energy will increase and this emphasizes the significance of electrical power engineering in the energy infrastructure of the country. The article constitutes an attempt to assess selected elements characterising the Polish energy market. For that purpose, selected quantitative methods which assess the dynamics and correlation were used, and dynamic econometric models were constructed which described these elements both in cause and effect and autoregressive terms. On the basis of the constructed models, forecasts for next years were prepared, assessing at the same time the errors in these forecasts. The information received as a result of the applied methods may constitute a basis for assessing the situation in the energy market in Poland and at the same time for assessing whether the signals transmitted by the environment were properly analyzed by the entities pursuing the objects of the energy policy.
根据绿色物流概念,任何一种商业活动对环境的影响都是主要问题之一。全球物流倾向于减少污染和能源消耗,为子孙后代节约自然资源,并优化各种活动来实现这一目标。在本文中,我们分析了波兰的能源市场,目的是提出能源指标及其多年来的演变,这允许在绿色物流范围内进行广义干扰。根据“Polityka energetyczna Polski do 2030 r”文件中提出的预测和分析工作的结论。[波兰到2030年的能源政策],假设全国电力消耗将增加80- 93%。因此,假设社会对电能的依赖将会增加,这强调了电力工程在国家能源基础设施中的重要性。这篇文章试图评估波兰能源市场的某些特征。为此,使用了评估动态和相关性的选定定量方法,并构建了动态计量经济模型,以因果关系和自回归术语描述这些要素。在建立的模型的基础上,对未来几年进行了预测,同时对这些预测的误差进行了评估。采用这些方法所收到的资料可作为评估波兰能源市场情况的基础,同时也可作为评估追求能源政策目标的实体是否对环境所传递的信号进行了适当分析的基础。

Traffic management solutions are increasingly called to address problems of transport and mobility and nowadays event to address the environmental impact. This is possible adding the constraints related to the reduction of gases emissions. In particular, traffic control uses strategy to reduce bottlenecks, travel time and coasts. Although it is usually assumed that an improved traffic flow will result in lower vehicle emissions, little scientific research has been spent on the effects of traffic control on emissions. Moreover, because changes in traffic flow do not necessarily influence travel times, noise and air quality in the same way, there is a clear need for a combined approach. This paper reports on a computational study in which a macroscopic traffic simulation model is combined with model of CO2 emission model. Through the simulation the model is used to investigate the influence of traffic intensity, and parameters on the gases emission. It was found that the introduction of a traffic control, lower the emissions depending on traffic flow and velocity constraints.
交通管理解决方案越来越多地被要求解决交通和流动性问题,现在的事件是解决环境影响。加上与减少气体排放有关的限制,这是可能的。特别是,交通管制使用策略来减少瓶颈、旅行时间和海岸。虽然人们通常认为交通流量的改善会导致车辆排放的降低,但很少有科学研究用于交通管制对排放的影响。此外,由于交通流量的变化不一定以同样的方式影响旅行时间、噪音和空气质量,因此显然需要采取综合办法。本文报道了将宏观交通模拟模型与CO2排放模型相结合的计算研究。通过仿真,研究了交通强度和交通参数对尾气排放的影响。研究发现,引入交通管制,降低排放取决于交通流量和速度的约束。

System dynamics simulation to determine safety stock for a single-stage inventory system 单级库存系统安全库存确定的系统动力学仿真

In this paper, a single-stage inventory system, which analytical method results exist in previous literature is considered. This case is one of an adaptive base-stock policy for a single-item inventory system, where the demand process is no-stationary. The demand process is modeled as an integrated moving average process for which an exponential-weighted moving average provides the optimal forecast. The case study objective is about how characterize the required inventory and how identify the safety stock requirements. For this purpose, a system dynamics approach is developed through a flow diagram model and simulated using Vensim® software. The results of the comparative study show that system dynamics approach is very useful. The system dynamics models can provide increased comprehension of, and improved insight into, the performance of an inventory system. The extension of system dynamics seems very interesting for the analysis of complex supply chain problems. In fact, analytical methods are perceived to be unhelpful by management or may require oversimplification.
本文考虑了以往文献中存在的分析方法结果的单阶段库存系统。本案例是单项目库存系统的自适应基本库存策略之一,其中需求过程是非平稳的。需求过程建模为一个综合移动平均过程,其中指数加权移动平均提供了最优预测。案例研究的目标是关于如何描述所需库存以及如何确定安全库存需求。为此,通过流程图模型开发了系统动力学方法,并使用Vensim®软件进行了仿真。对比研究结果表明,系统动力学方法是非常有用的。系统动力学模型可以提高对库存系统性能的理解和洞察。系统动力学的扩展对于分析复杂的供应链问题显得非常有趣。事实上,分析方法被认为对管理没有帮助,或者可能需要过度简化。

In this paper we propose a model of decision support to optimize the physical flow of the supply chain port. The physical flow, considered here, is a group of containers. To optimize these flows, we have developed a mathematical model proposing an allocation of incoming vessels on the waterfront in a way to minimize the total distance traveled by containers loaded / unloaded in the port area. This model was solved by using a genetic algorithm. Calculation results are presented and compared with those obtained by a commercial solver (CPLEX).

One of the most difficult question to treat, is how to evaluate, build and maintain a sustainable Ambient intelligence (AmI) service? how it can enable society to enjoy a sufficiently high level of life without destroying its natural and environmental support? To conduct this research, the researcher should cover a variety of technological fields that cooperate together to establish an AmI service. In this work we propose a Framework assessment services in the field of ambient mobility. First of all, we introduce a systematic literature review in order to evaluate ambient intelligence services by presenting a full research related to ubiquitous and ambient intelligence evaluation. In our research we focus to extract metric and methodology then we enumerate the sub-criteria following the sustainability definition. Next, we define the sub-criteria for the assessment of sustainability while justifying the choice of these criteria is always based on previous systematic review methodology. Finally, we summarize a method for evaluating uncertain approaching based on human reasoning; fuzzy logic.

Evaluating emergency lateral transshipment policies using simulation-based approaches 使用基于模拟的方法评估紧急横向转运政策
Pub Date : 2013-05-29 DOI: 10.1109/ICADLT.2013.6568504

This paper deals with a lateral transshipment models involving two-echelon supply chain network, with a single supplier at the higher echelon and two retail locations at the lower. Lateral transshipment is considered as an option at each reorder decision under the periodic review standard (R, s, S) replenishment policy. The purpose of this paper is twofold. Firstly, a metamodel-based simulation optimization approach is applied to find the optimal values of s and S, for each retailer. Secondly, a series of simulation experiments are performed to find the best transshipment policy, in terms of smallest total cost and disservice rate. The tested policies are no pooling, complete pooling and various partial pooling policies according to what the threshold levels of physical stock are selected. An important finding is that each tested transshipment policy is considerably superior to a policy of no such transshipments, although at the expense of increased transportation activity. The best transshipment policy is such partial pooling with exactly s as the well-chosen value of the threshold level. Partial pooling is very interesting transshipment policy and should be further addressed in future research.
本文研究了一个包含两层供应链网络的横向转运模型,其中上层有一个供应商,下层有两个零售点。在定期审查标准(R, s, s)补充政策下,横向转运被认为是每个再订货决策的一种选择。本文的目的是双重的。首先,采用基于元模型的仿真优化方法,找出每个零售商s和s的最优值。其次,进行了一系列的仿真实验,从总成本和损失率最小的角度寻找最佳转运策略。根据选择的物理库存阈值级别,测试的策略是无池化、完全池化和各种部分池化策略。一项重要的发现是,每一项经过检验的转运政策都比不进行这种转运的政策优越得多,尽管代价是增加运输活动。最好的转运策略是这样的部分池化,它恰好是阈值水平的精心选择值。部分集运是一种非常有趣的转运策略,值得在今后的研究中进一步探讨。

Partial pooling is very interesting transshipment policy and should be further addressed in future research.","PeriodicalId":269509,"journal":{"name":"2013 International Conference on Advanced Logistics and Transport","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2013-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134046290","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Road safety in France has a history that explains the latest developments that can be observed today. This example is rich in lessons that can be used by other countries, including the Maghreb. Road safety is first of all a national concern. This means it is a top-down process. In 1972, a road safety public policy has been decided leading to a significant reduction in the number of victims. Policy today is mainly focused on the control of driver behavior, explaining the transfer of the jurisdiction on this policy, from Department in charge of Transportation to the Department of the Interior. The local institutional levels have now an ever more important role in prevention strategies due to the decentralization and transfer of national road networks to local communities. In the countryside the safety issue remains very high but the capacity for action remains low because of road network length and the increase in traffic generated by suburbanization. In urban areas, the organizational safety — as it unfolds for work safety — is too often overlooked when it comes to preventing road accidents. In particular, the design of a real strategy focused locally on the steering action by safety, is not developed in France. It is as if the slogan of sustainability pays no attention to road safety.
法国的道路安全有一段历史,可以解释今天可以观察到的最新发展。这个例子具有丰富的经验教训,可供包括马格里布在内的其他国家借鉴。道路安全首先是一个全国性的问题。这意味着这是一个自上而下的过程。1972年,通过了一项道路安全公共政策,大大减少了受害者人数。今天的政策主要集中在驾驶员行为的控制上,解释了这一政策的管辖权从负责交通的部门转移到内政部的原因。由于国家道路网络的权力下放和向地方社区的转移,地方机构一级现在在预防战略中发挥着越来越重要的作用。在农村,安全问题仍然非常严重,但由于道路网络长度和郊区化造成的交通增加,采取行动的能力仍然很低。在城市地区,当涉及到预防道路交通事故时,组织安全——正如它所展现的安全生产——往往被忽视。特别是,真正的战略设计集中在当地的安全转向行动,没有在法国发展。可持续发展的口号似乎没有注意到道路安全。
