This paper presents an agile approach for managing ferry terminals. We propose a double-stage model that forecasts traffic. The hybrid model is based on quantitative tools. First, we search for associations in data and then, we develop a time series analysis. The specific objectives of the study are firstly to survey and collect data at a disaggregated level in terms of passenger and vehicle flows and time periods; and secondly, to develop forecasts on short-term using a combination of the proposed techniques. We think that the simultaneous application of historical analogy and time series forecasting is a powerful tool to predict the future traffic. Additionally, the methodological procedure proposed in this paper is general enough to be applied to other traffics and ports.
本文提出了一种管理轮渡码头的敏捷方法。我们提出了一个预测交通量的双阶段模型。混合模型基于定量工具。首先,我们在数据中搜索关联,然后,我们开发了一个时间序列分析。该研究的具体目标首先是在乘客和车辆流量以及时间段方面进行分类调查和收集数据;第二,结合所提出的技术进行短期预测。我们认为,同时应用历史类比和时间序列预测是预测未来交通的有力工具。此外,本文提出的方法论程序足够通用,可以应用于其他交通和港口。

Surface roughness is reduced by optimising the machining parameters. This research analyses the effect of machining parameters on surface quality of aluminium 2024 T351 in milling of semi-circular pocket with carbide tool on 5-axis hybrid parallel kinematic machine (HPKM). Three different segmented surfaces were selected on semi-circular pocket and investigated the influence of machining parameters. The selected parameters are spindle speed, feed rate and depth of cut. Investigation of this study results in the optimum parameters that could produce good surface finish. The effect of these cutting parameters is evaluated using L9 Taguchi orthogonal array, s/n ratio, analysis of variance (ANOVA). Based on the result analysis, good surface finish can be obtained at high cutting speed, low feed rate, and low depth of cut. Also, the maximum influence of feed rate among the selected surface segments was ascertained.
通过优化加工参数,降低了表面粗糙度。研究了在五轴混合并联机床(HPKM)上用硬质合金刀具铣削2024 T351铝合金半圆袋时,加工参数对其表面质量的影响。选取了三种不同的半圆弧口袋曲面,研究了加工参数对其加工的影响。所选参数为主轴转速、进给速度和切削深度。通过研究,确定了能产生良好表面光洁度的最佳工艺参数。采用L9田口正交法、信噪比、方差分析(ANOVA)对各切削参数的影响进行评价。结果分析表明,在高切削速度、低进给速度和低切削深度条件下,可获得良好的表面光洁度。同时,确定了进给量对所选曲面段的最大影响。

Transdisciplinary processes have been the subject of research since several decades already. Transdisciplinary processes are aimed at solving ill-defined and socially relevant problems. Many researchers have studied transdisciplinary processes and have tried to understand the essentials of transdisciplinarity. Many engineering problems can be characterised as ill-defined and socially relevant, too. Although transdisciplinary engineering cannot widely be found in the literature yet, a transdisciplinary approach is deemed relevant for many engineering problems. With this paper we aim to present an overview of the literature on research into transdisciplinary processes and investigate the relevance of a transdisciplinary approach in engineering domains. After a brief description of past research on transdisciplinarity, implications for engineering research, engineering practice, and engineering education are identified. In all three areas, the current situation is described, while challenges are identified that still exist. The paper ends with a research agenda for transdisciplinary engineering.
跨学科过程自几十年以来一直是研究的主题。跨学科程序旨在解决定义不清和与社会相关的问题。许多研究人员研究了跨学科的过程,并试图理解跨学科的本质。许多工程问题也可以被描述为定义不清和与社会相关。尽管跨学科工程尚未在文献中广泛找到,但跨学科方法被认为与许多工程问题相关。本文旨在概述跨学科过程研究的文献,并研究跨学科方法在工程领域的相关性。在简要描述了过去对跨学科的研究之后,确定了对工程研究、工程实践和工程教育的启示。在这三个领域,都描述了目前的局势,同时确定了仍然存在的挑战。论文最后提出了跨学科工程的研究议程。

Leagile manufacturing has emerged as an innovative strategy in the last two decades. In this paper, critical success factors (CSFs), affecting leagile manufacturing, have been identified through literature review and discussion with industrialists and academics. Fuzzy decision making trial and evaluation laboratory (DEMATEL) technique have been applied to divide the CSF's into cause and effect categories. It has been found that critical success factors 1 (collaborative relationship), 3 (strategic management), 5 (customer and market sensitiveness), 7 (human resource management), 11 (flexible manufacturing system), 12 (knowledge and IT management), 14 (availability of funds), and 15 (benchmarking) falls under cause group while critical success factors like 2 (management support towards implementation of policy), 4 (training and development programs), 6 (design and engineering), 8 (virtual enterprises), 9 (use of advance manufacturing technologies), 10 (supply chain management), and 13 (rapid reconfiguration) falls under effect group. The research will help the managers to identify the key factors and work accordingly in proper directions to implement leagile system in their organisations. Leagile system results in increased profitability, better quality of products, better customer satisfaction, better sales, increased productivity, increased sales, reduced manufacturing lead time, etc.
在过去的二十年里,敏捷制造已经成为一种创新战略。本文通过与工业家和学者的文献回顾和讨论,确定了影响敏捷制造的关键成功因素(CSFs)。应用模糊决策试验与评价实验室(DEMATEL)技术对脑脊液进行因果分类。研究发现,关键成功因素1(协作关系)、3(战略管理)、5(客户和市场敏感性)、7(人力资源管理)、11(柔性制造系统)、12(知识和It管理)、14(资金可用性)和15(标杆管理)属于事业组,而关键成功因素2(对政策实施的管理支持)、4(培训和发展计划)、6(设计和工程)、8(虚拟企业)、9(先进制造技术的使用)、10(供应链管理)和13(快速重构)属于有效组。该研究将帮助管理者确定关键因素,并在适当的方向上相应地工作,以在其组织中实施敏捷系统。敏捷系统可以提高盈利能力、提高产品质量、提高客户满意度、提高销售、提高生产率、增加销售、减少制造前置时间等。

The performance of untreated/uncoated, wiper, deep cryogenically treated, and coated (TiN, TiAlN and TiCN) carbide inserts using response surface methodology in turning of AISI 52100 steel, was evaluated in this study. Type of insert, cutting speed, feed and depth of cut were the factors investigated. The response variables analysed were tool flank wear and surface roughness. Basing on RSM central composite design, an experimental plan (L18 OA) was developed. The ANOVA results signify that the suggested mathematical models could adequately elucidate the performance indicators within the range. The generated regression equation reveals that the flank wear is mainly influenced by the type of insert followed by cutting speed. The surface roughness was majorly affected by the type of insert followed by feed rate. Machined surface topographies and tool flank wear mechanism were analysed by examining the SEM micrographs. RSM multi-response optimisation was executed so as to optimise the turning parameters.
在本研究中,使用响应面方法对AISI52100钢车削中未处理/未涂覆、擦拭、深低温处理和涂覆(TiN、TiAlN和TiCN)碳化物刀片的性能进行了评估。刀片类型、切削速度、进给量和切削深度是研究的因素。分析的响应变量为刀具侧面磨损和表面粗糙度。在RSM中心复合材料设计的基础上,开发了实验方案(L18OA)。方差分析结果表明,所提出的数学模型可以充分阐明该范围内的绩效指标。生成的回归方程表明,刀面磨损主要受刀片类型和切削速度的影响。表面粗糙度主要受刀片类型和进给速度的影响。通过扫描电镜分析了加工表面形貌和刀具侧面磨损机理。执行RSM多响应优化,以优化转弯参数。

A systemic approach to applying asset orchestration theory 应用资产编排理论的系统方法

The paper proposes and uses a reference model of asset orchestration which characterises common organising relationships observed between the 'resource-based view' and the 'dynamic capabilities view' of firms. This reference model helps to visualise and communicate alternative common decision-making contexts needed to sustain competitive responses in firms through their lifetime, and thereby through the lifetime of the products and the services they realise. Little present literature describes the practical application of emergent asset orchestration (AO) concepts. Hence, the present authors use their reference model to capture actual AO data within two case study firms. The captured data shows how AO theory can be deployed to direct strategic decision making towards sustainable configuration and deployments of a firms resource portfolio. Essential characteristics of the new reference model and of how it can be applied are reported in this paper.
本文提出并使用了一个资产编排的参考模型,该模型描述了在企业的“基于资源的视角”和“动态能力视角”之间观察到的共同组织关系。该参考模型有助于可视化和传达企业在其整个生命周期内,从而在其实现的产品和服务的生命周期内维持竞争反应所需的替代通用决策环境。目前很少有文献描述紧急资产编排(AO)概念的实际应用。因此,本作者使用他们的参考模型来获取两家案例研究公司的实际AO数据。捕获的数据显示了AO理论如何被部署来指导企业资源组合的可持续配置和部署的战略决策。本文报告了新参考模型的基本特征以及如何应用它。

Chinese government recently launched one belt one road to reform and speed up the development of Chinese economic in the world. One Belt One Road (OBOR) strategy heavily relied on the traditional logistical trade routes including terrestrial and oceanic Silk Road. Logistics performance may play a vital role for implementing the One Belt One Road plan. Especially, third party logistics providers as supporting members to carry out value-adding supply chain activities in one belt one road. According to literature review, supply chain risk is an issue to obstruct the development of logistics performance. The purpose of this paper is to present a conceptual framework for managing supply chain risks and improving logistics performance under the OBOR initiative in Chinese third party logistics service providers. There are very few studies on risk management in the OBOR initiative. We focus on the innovation, customer response and flexibility in the third-party logistics providers. This would provide a guide for both academics and practitioners to manage supply chain risks and improve logistics performance and enlighten them to pay attention to supply chain risk management in the Chinese third party logistics sector. In addition, this contributes to the supply chain and logistics management in One Belt One Road literature.
中国政府最近启动了“一带一路”改革,加快了中国经济在世界范围内的发展。一带一路战略在很大程度上依赖于包括陆上和海上丝绸之路在内的传统物流贸易路线。物流绩效可能对“一带一路”计划的实施起着至关重要的作用。特别是第三方物流供应商作为支持成员,在一带一路开展增值供应链活动。根据文献综述,供应链风险是阻碍物流绩效发展的一个问题。本文的目的是为中国第三方物流服务提供商在OBOR倡议下管理供应链风险和提高物流绩效提供一个概念框架。OBOR倡议中关于风险管理的研究很少。我们专注于第三方物流供应商的创新、客户响应和灵活性。这将为学术界和实务界管理供应链风险、提高物流绩效提供指导,并启发他们关注中国第三方物流行业的供应链风险管理。此外,这有助于“一带一路”文献中的供应链和物流管理。

Home healthcare service provides daily medical services at patients' homes. The service aims to satisfy the patients' requirements which must be done by qualified staff visiting them at the right time. This paper proposes a new framework integrating the heuristic search and fuzzy logic with knowledge acquisition to develop reliable and effective decision to match qualified staff to offer the service with the minimum cost, under preference consideration and feasible time-slots. The framework is designed based on the hierarchical approach dividing the system into two layers: high and low level. The high level is responsible for retrieving information, such as patients' locations and operation cost while the lower level with fuzzy logic to estimate a set of the level of staff selection to create the service plan. Our empirical study of 40 medical tasks with eight carers shows that the framework has a potential to provide improved solutions than the original.
家庭医疗服务在患者家中提供日常医疗服务。这项服务旨在满足患者的要求,必须由合格的工作人员在适当的时间探访患者。本文提出了一种新的框架,将启发式搜索和模糊逻辑与知识获取相结合,以制定可靠有效的决策,在偏好考虑和可行的时间段内,匹配合格的员工以最低成本提供服务。该框架是基于分层方法设计的,将系统分为两层:高层和底层。高层负责检索信息,如患者的位置和手术费用,而下层则用模糊逻辑来估计一组人员的选择水平,以创建服务计划。我们对8名护理人员的40项医疗任务进行的实证研究表明,该框架有可能提供比原来更好的解决方案。

Sophisticated medical treatment often requires a multidisciplinary approach and a number of follow ups. This can limit the opportunity of patients who live in remote areas to access quality and proper treatment due to the fact that healthcare services in Thailand are relatively centralised. The study proposes a collaborative framework to empower local healthcare clusters to service patients in their area of residence more effectively to minimise patient referral to their hub hospital. Several common features and constraints are identified. The investigation is to develop a practical ICT solution based on a case study of cleft-lip/palate treatment using a network in Northern Thailand. Initial implementation of this enterprising project is outlined in this paper. The current progress includes two applications that have been developed to address the high priority issues of collaborative networking. One is to support data sharing for medical teams and the other is to facilitate patients to access better medical services.
复杂的医疗通常需要多学科的方法和大量的随访。由于泰国的医疗服务相对集中,这可能会限制生活在偏远地区的患者获得优质和适当治疗的机会。该研究提出了一个合作框架,使当地医疗保健集群能够更有效地为居住区的患者提供服务,以最大限度地减少患者转诊到其中心医院的情况。确定了几个常见的特征和约束条件。该调查旨在根据泰国北部使用网络进行唇腭裂治疗的案例研究,开发一种实用的ICT解决方案。本文概述了这一创新项目的初步实施情况。目前的进展包括为解决协作联网的高度优先问题而开发的两个应用程序。一个是支持医疗团队的数据共享,另一个是方便患者获得更好的医疗服务。

Enterprise information systems (EIS) are directly implied in the global performance of an organisation. Nevertheless, their potential rigidity in comparison with the required fast evolution of the supported organisation remains an important open research question. The proposed research work aims to define and evaluate the agility of an EIS, in order to assist both software engineers and business managers in EIS improvement projects. In particular, a framework is proposed to structure the different existing metrics on agility according to the improvements needs and the intrinsic characteristics of an information system.
企业信息系统(EIS)直接隐含在一个组织的整体绩效中。然而,与支持组织所需的快速发展相比,它们的潜在刚性仍然是一个重要的开放研究问题。拟议的研究工作旨在定义和评估环境影响信息系统的敏捷性,以便在环境影响信息系统改进项目中帮助软件工程师和业务经理。特别地,根据改进需求和信息系统的内在特征,提出了一个框架来组织现有的不同敏捷性度量。
