The automobile industries are more competitive and customer demand is volatile. The customers are willing to buy the product at low cost with high quality. So common principle is created to reduce the wastage and increase the efficiency of the industry. Lean manufacturing is the best principle to adopt the manufacturing industry. The main aim of this project is reduce the wastage, cost and increase the productivity of the industry. Using lean tools just in time (JIT), kanban, value stream mapping (current and future state) and man machine chart (current and future) for reduce wastage and cost. In current state value stream map, the waste area is identified. Finally, non-value added time is reduced to 28.7%. The value added time is reduced to 27.84%. The percentage value addition is increased from 3.25% to 3.29%, the total inventory is reduced to 25.07% and man machine ratio is improved as 1.52: 1.26.

Past and recent disasters, both man made (technological) and natural (non-technological) have produced innumerable casualties and unimaginable harm to life and property. Though the management of factories and the authorities has responded to the challenge and introduced number of measures to minimise the hazards, the real fact is that accident cannot be completely eliminated. For this purpose, it is necessary to prepare an emergency preparedness plan for every administrative or industrial area by the competent authorities. With the help of computer simulation models, knowledge of chemicals'; it's behaviour and availability of input data, it is possible to predict the area affected under different emergency scenarios. Keeping in view the plotting requirement along with linkages of various databases, it has been considered appropriate to use computer aided emergency management system for effective mitigation and response during an industrial disaster. This paper proposes a composition of a computer aided emergency management system.
过去和最近的灾害,无论是人为的(技术的)还是自然的(非技术的),都造成了无数的伤亡,对生命和财产造成了难以想象的损害。尽管工厂的管理和当局已经对这一挑战做出了回应,并采取了一些措施来尽量减少危险,但实际情况是,事故不可能完全消除。为此目的,主管当局有必要为每个行政或工业区域制定应急准备计划。借助计算机模拟模型,对化学品的知识;它的行为和输入数据的可用性,可以预测在不同的紧急情况下受影响的区域。考虑到绘图要求以及与各种数据库的联系,人们认为在工业灾害期间使用计算机辅助应急管理系统进行有效的缓解和反应是适当的。本文提出了一种计算机辅助应急管理系统的组成。

Cement industries are one of the growing large scale industries which play as a backbone for developing countries. This paper discusses the analysis of losses and wastage in cement manufacturing process and its rectification using lean tools and methodology mathematically. Employee's psychology varies with every new management planning, so psychology towards new lean management planning is also analysed through questioner to correlate lean management planning satisfaction to stress, job satisfaction, and safety improvement individually using Karl Pearson correlation in SPSS software. The data has been collected from various cement industries at each stage and analysed. Lean management planning resulted in a reduction of wastage in the transportation of mining, over processing and increase in efficiency of the separator in grinding mills, kiln quality control, packing plant efficiency improvement. The correlation analysis also resulted in stress reduction, improvement in job satisfaction and safety conditions with new lean management planning. Finally the result concludes that new lean management planning has positive correlation with the employee's psychology.
水泥工业是发展中的大型工业之一,是发展中国家的支柱。本文运用精益工具和数学方法,对水泥生产过程中的损耗和损耗进行了分析和纠正。员工的心理随着每一项新的管理计划而变化,因此,通过提问者对新的精益管理计划的心理进行分析,利用SPSS软件中的Karl-Pearson相关性,将精益管理计划满意度与压力、工作满意度和安全改进单独相关。数据是从各个阶段的水泥行业收集并分析的。精益管理计划减少了采矿运输中的浪费、过度加工,提高了磨机分离器的效率、窑炉质量控制、包装厂效率的提高。相关性分析还表明,通过新的精益管理计划,压力减轻,工作满意度和安全条件得到改善。最后得出结论:新的精益管理计划与员工心理呈正相关。

In order to optimise a supply chain, the effective management of suppliers plays a key role. Firms seeking competitive advantage are participating in cooperative supply chain arrangements, such as strategic partnerships, which combine their individual strengths and unique resources. Supplier selection is a multi-criteria decision making problem which includes both qualitative and quantitative factors. In the present scenario environmental criteria should also be given due importance, this further increases the challenge of supplier selection. Generally, decision makers' judgments are often uncertain and cannot be estimated by an exact numerical value. The grey systems theory is a powerful tool to deal with uncertain information. This paper presents a structured model for evaluation and selection of strategic supplier. Stepwise Weight Assessment Ratio Analysis (SWARA) is applied to decision making in order to calculate the relative importance of the criteria. The COmplex PRoportional ASsessment of alternatives with grey relations (COPRAS-G) method is used for supplier evaluation and selection of strategic supplier. A case study is presented to demonstrate the applicability of the proposed model to select a strategic green supplier.
为了优化供应链,供应商的有效管理起着关键作用。寻求竞争优势的企业正在参与合作供应链安排,如战略伙伴关系,这将他们的个人优势和独特资源结合起来。供应商选择是一个包含定性和定量因素的多准则决策问题。在目前的情况下,环境标准也应给予应有的重视,这进一步增加了选择供应商的挑战。一般来说,决策者的判断往往是不确定的,不能用一个精确的数值来估计。灰色系统理论是处理不确定信息的有力工具。本文提出了一个战略供应商评价与选择的结构化模型。逐步权重评估比率分析(SWARA)应用于决策,以计算标准的相对重要性。采用灰色关系复比例评价(COPRAS-G)方法对供应商进行评价,并对战略供应商进行选择。通过一个案例分析,证明了该模型在绿色供应商战略选择中的适用性。

There has been significant interest in integration of internet of things (IOT) and healthcare both in academic and the corporate world. This can be seen from the fact by the number of conferences held and number of special issues in journals that have been published. To establish further in this domain, the purpose of this research is two-fold. First it does literature review in healthcare and IOT from 151 papers published from 1998 to 2016. Second, it summarises findings from literature review in two parts. In the first part, it identifies the antecedents that impact both affordable quality healthcare and developing an enterprise network for IOT. In the second part, it integrates factors that affect both affordable healthcares with IOT. The results of this research will be useful for both practitioners and academicians as the paper discusses how to design a IOT based healthcare network that will reduce cost of healthcare while preventing chronic diseases. The paper also shows the limitations of the present research while describing stimuli for further research.
学术界和企业界都对物联网(IOT)和医疗保健的整合产生了浓厚的兴趣。这一点可以从举办的会议数量和在期刊上发表的特刊数量中看出。为了在这一领域进一步建立,本研究的目的是双重的。首先,对1998年至2016年发表的151篇医疗保健和物联网论文进行了文献综述。其次,将文献综述的发现分为两部分进行总结。在第一部分中,它确定了影响可负担的高质量医疗保健和为物联网开发企业网络的前因。在第二部分中,它整合了影响可负担医疗保健与物联网的因素。这项研究的结果将对从业者和学者都有用,因为本文讨论了如何设计一个基于物联网的医疗网络,以降低医疗成本,同时预防慢性疾病。本文还指出了目前研究的局限性,同时描述了进一步研究的刺激因素。

The problem of deciding the contribution of each generator in a power system is complex. Where some generators are more cost effective, others have cleaner operation. Right choice of generators could save thousands of dollars in operating cost or prevent release of several tons of noxious fumes like NO2 and SO2 annually. Rising complexity of modern power systems and special efficiency improvement methods like valve point loading, demand newer means to find this vital balance between cost and emission. This paper aims to find a solution to this problem by the use of an algorithm inspired by the flight pattern of moths. Like a moth drawn to a flame, this algorithm seeks to minimise both cost as well as emission. The standard IEEE 30 bus test system is considered as the control case and the results obtained are compared with other such algorithms to demonstrate the effectiveness of MFO.
确定电力系统中每台发电机的贡献是一个复杂的问题。有些发电机更具成本效益,有些则运行更清洁。选择正确的发电机可以节省数千美元的运营成本,或每年防止释放数吨有毒烟雾,如二氧化氮和二氧化硫。现代电力系统的复杂性和特殊的效率提高方法,如阀点加载,需要新的方法来找到成本和排放之间的重要平衡。本文旨在利用一种受飞蛾飞行模式启发的算法来解决这一问题。就像飞蛾扑火一样,这个算法寻求最小化成本和排放量。以标准的ieee30总线测试系统为控制例,并将所得结果与其他同类算法进行了比较,验证了该算法的有效性。

Cloud computing is a kind of architecture deals with the principles of virtualisation and also promote online computing platform as well as services. Tools of the information technology such as monitor, printers, databases, other applications and packages come under the preview of cloud computing. It is also considered as a cloud platform along with cloud architecture. This helps cost saving due to less software, hardware, and IT packages in the in-house settings. Cloud computing also promotes side by side the online availability. Moreover cloud computing saves initial cost as it is offered by third party and thus seeks no need to connect to the service or cloud provider. In cloud computing, internet plays an important role for converged hardware, software and IT applications. Cloud computing has healthy potentialities in iSchools as such academic units are offered academic programs on information and computing related domains. The paper presented the overview on cloud computing and its features with potentialities of the domain in iSchools and allied branches.
云计算是一种处理虚拟化原理的架构,同时也促进了在线计算平台和服务。显示器、打印机、数据库、其他应用程序和软件包等信息技术工具都属于云计算的预览范围。它也被认为是一个云平台和云架构。这有助于节省成本,因为内部环境中的软件、硬件和IT包更少。云计算同时也促进了在线可用性。此外,云计算节省了由第三方提供的初始成本,因此无需连接到服务或云提供商。在云计算中,互联网在融合硬件、软件和IT应用方面发挥着重要作用。云计算在iSchool中具有健康的潜力,因为这些学术单位提供信息和计算相关领域的学术课程。本文在iSchools及其相关分支机构中介绍了云计算及其特点和该领域的潜力。

Supply chain is a network of facilities with varying conflicting objectives and decision making is a complex process. The uncertainty in demand increases complexity in inventory control mechanism. Backordering, partial backordering and lost-sales are considered in the inventory management to characterise the excess demand. In the present competitive scenario, mostly consumers have no patience to wait and show urgency to buy their goods failing which the management has to meet a huge loss of supply chain members and hence the profit. There are very few research works regarding lost-sales parameter in the area of multi-echelon inventory systems. It is felt that the proposed modified gene-wise genetic algorithm (MGGA) supply chain model which so far not applied in this process may help to determine best base stock levels and review periods with lost sales particularly at retailer end which minimised total supply chain cost.
供应链是一个具有不同冲突目标的设施网络,决策是一个复杂的过程。需求的不确定性增加了库存控制机制的复杂性。库存管理中考虑了延期交货、部分延期交货和销售损失,以表征超额需求。在目前的竞争环境中,大多数消费者没有耐心等待并表现出购买商品的紧迫性,否则管理层不得不承受供应链成员的巨大损失,从而获得利润。在多级库存系统中,关于损失销售参数的研究很少。人们认为,迄今为止尚未在该过程中应用的所提出的改进基因遗传算法(MGGA)供应链模型可能有助于确定最佳基本库存水平和审查期,尤其是在零售商端,这将使总供应链成本降至最低。
