基于协调发展度的重大工程团队免疫系统健康评价研究

为评价重大工程团队免疫系统的健康和协调发展状况，本文提出了一种基于协调发展度的评价模型。首先通过文献查询和深度访谈，构建能够体现重大工程团队免疫系统特征的健康评价指标体系；其次利用改进的DEMATEL确定指标权重，然后采用多层次模糊综合评价将相关指标定量化，最终得出重大工程团队免疫系统的健康指数和协调发展度；再次确立重大工程团队免疫系统健康等级和协调发展度划分标准，同时提出免疫系统健康的跟踪评价策略；最后，利用本文模型对某跨国输气管道工程团队的免疫系统进行实证研究。结果表明，协调发展度模型既能反映重大工程团队免疫系统的整体健康程度，又能衡量固有性免疫和适应性免疫的协调发展状况，同时对免疫系统健康的跟踪评价也取得了良好效果。     

集体行动视角下的制度逻辑演化机制研究

通过对我国专车服务市场制度变革过程的纵向案例研究，探讨了组织场域中的集体行动如何推动制度逻辑演化的内在机制问题。研究发现：制度逻辑的演化过程主要经历了分离、冲突和共存三种状态，不同的制度逻辑的演化是由行动主体能动性策略和资源利用所构建的集体行动模式差异性驱动的。制度变革机会的涌现促使场域中的行动主体采用协调性的集体行动模式，促成了新制度逻辑的生成，并导致了新、旧两种制度逻辑的分离；在制度变革机会变得模糊的场域中，行动主体非协调的集体行动促使新、旧两种制度逻辑之间的激烈冲突；而在制度变革机会沉没的情境下，行动主体再协调性的集体行动最终促成了新、旧两种制度逻辑的共存。研究结论对我国当前复杂制度环境下新兴业态的发展以及传统业态的协同治理提供了重要的借鉴和启示。     

National culture and organisational culture in lean organisations: a systematic review

Despite the extensive literature suggesting that culture plays a key role in lean implementations, no previous review has focused on the topic. This study is a systematic review of the literature that synthesises over two decades of publications according to the levels of national culture (NC) and organisational culture (OC) and maps which cultural dimensions foster or hinder lean implementation. In terms of NC, this study shows that Japanese cultural traits might hinder lean, such as masculinity and power distance, hence avoiding the over simplification that lean is a country-specific management approach. In terms of OC, the literature review unveils a lack of consensus and underlines two paradoxes, namely the co-existence of both process and result-focused orientations and both normative and pragmatic approaches. This review ultimately offers a relevant agenda for lean research as well as a guide for managers who face the challenge of implementing and sustaining lean in their organisations.     

互联网医疗服务法律监管研究

随着互联网技术的进步以及医疗改革的深入,互联网医疗服务成为新生业态.然而,我国互联网医疗服务法律监管体系还不够完善,缺乏统一规范的监管体系,多头监管、个人隐私隐患大、纠纷处理解决机制不健全等现实困境尚未解决,不利于互联网医疗服务行业的发展和人民群众身心健康.为解决上述问题,通过梳理发达国家的成功经验,如美国的移动医疗应用程序监管和个人隐私保护、欧盟的互联医疗数据管理、英国的行业协会监管等,结合我国现有国情,建议从完善立法体系、建设隐私保护机制、构建行业监管、明晰医疗服务主体责任等方面健全互联网医疗法律监管制度,以期推动互联网医疗服务行业发展,保障医患双方的合法权益.     

Spatial Risk Analysis of Power Systems Resilience During Extreme Events

The increased frequency of extreme events in recent years highlights the emerging need for the development of methods that could contribute to the mitigation of the impact of such events on critical infrastructures, as well as boost their resilience against them. This article proposes an online spatial risk analysis capable of providing an indication of the evolving risk of power systems regions subject to extreme events. A Severity Risk Index (SRI) with the support of real‐time monitoring assesses the impact of the extreme events on the power system resilience, with application to the effect of windstorms on transmission networks. The index considers the spatial and temporal evolution of the extreme event, system operating conditions, and the degraded system performance during the event. SRI is based on probabilistic risk by condensing the probability and impact of possible failure scenarios while the event is spatially moving across a power system. Due to the large number of possible failures during an extreme event, a scenario generation and reduction algorithm is applied in order to reduce the computation time. SRI provides the operator with a probabilistic assessment that could lead to effective resilience‐based decisions for risk mitigation. The IEEE 24‐bus Reliability Test System has been used to demonstrate the effectiveness of the proposed online risk analysis, which was embedded in a sequential Monte Carlo simulation for capturing the spatiotemporal effects of extreme events and evaluating the effectiveness of the proposed method.     

Integrating risk and performance management in quality management systems for the development of complex bespoke systems (CBSs)

Abstract

Risk and performance management are at the core of complex bespoke systems (CBSs). CBSs are developed to customer–specified requirements in terms of structure, functionality and conformance. This article examines how risk and performance management are integrated as essential systems in the successful development of projects across multi-organizational functions in complex bespoke system (CBS) organizations. The article argues for the development of a quality management system that consists of two sub-processes: quality control and quality development. Using three case studies from engineering companies, we provide evidence and insights of the way change control, quality development and quality performance are developed in innovating business solutions.     

基于多目标加权灰靶决策模型的节能服务公司选择研究

用能方对节能服务公司（Energy Service Company，ESCO）的选择关系到合同能源管理（Energy Performance Contracting，EPC）能否顺利实施。从用能方的角度，采用灰色系统理论中的多目标加权灰靶决策模型，对存在多决策目标的ESCO选择问题进行研究。通过层次分析法确定ESCO的11个决策目标的决策权数，根据综合效果测度值的比较，最终实现最优对策的选择。本文为用能方的ESCO选择问题提供了一种新的思路。     

基于违约鉴别能力组合赋权的小企业信用评级——基于小型工业企业样本数据的实证分析

信用评级是衡量债务违约的可能性,因此评级体系要有违约风险识别能力,能够将违约客户和非违约客户显著地区分开.通过逼近理想点的思路,构建多目标规划模型求解最优的组合权重,并对中国某区域性商业银行1 814笔小型工业企业贷款进行实证分析.本文的创新与特色一是以非违约企业的数据到正理想点的距离代数和最小为第一个目标函数,以违约企业的数据到负理想点的距离代数和最小为第二个目标函数,构建多目标非线性规划模型进行组合赋权,在满足了“非违约企业的评价得分越高、违约企业的评价得分越低”要求的目标下得到最优的组合赋权的权重系数,使赋权结果保证了评级模型能够将违约企业与非违约企业最大地区分开.改变了现有研究的组合赋权脱离评价目的的弊端,改变了现有研究中违约与非违约企业的评价得分存在大量重叠、对两类企业的区分能力低的弊端.二是通过检验“违约企业的信用得分是否显著小于非违约企业的信用得分”的J-T非参数检验,验证信用评价模型的合理性.改变现有研究忽略对信用评价模型的合理性进行验证的弊端.三是经过实证,发现本研究建立的组合赋权模型的违约鉴别能力(Z=5.546)要高于现有研究的两种常用组合赋权模型、即基于方差最大的组合赋权(Z=4.298)和基于偏差最小的组合赋权(Z=5.182)     

随机需求环境下联产品系统价格与产量决策研究

基于固定比例生产技术和多产品随机需求的情形,研究了联产品制造商的两阶段产量和价格联合优化模型。通过反向倒推的优化求解,得到了联产品制造商的最优产量和价格决策以及变化规律。同时研究了需求服从均匀分布时,需求波动对均衡的影响。研究结果表明,在订货成本较低和一种产品的需求波动性较大时,当另外一种产品的波动增大,则该产品的最优订货量增大,同时价格下降。借助数值仿真,分析了价格敏感度和产出比例对最优决策和利润的影响。结果表明,在给定一种产品的价格敏感度时,另外一种的价格敏感度越大,那么该产品的价格就越低,制造商的订货量就下降。当一种产品的产出比例固定时,另一种产品的产出比例上升时,则该产品的价格下降,制造商的订货量下降,总利润上升。
