Paper aims: Extending the AHP abilities to new areas from explaining the famous Two-Envelope paradox to finding priorities as functions of auxiliary variables is suggested. Originality: The proposed innovative and advantageous approach permits to find the non-constant priorities via regression modeling for the exponential or Cobb-Douglas production functions. Research method: Transforming the ratio scale into the additive or logarithmic scales, which correspond to the multiplicative utility function, opens new possibilities in the multiple-criteria decision making. Main findings: Two-Envelop problem is resolved, priority vectors are presented as functions by auxiliary variables, preferences are predicted and profiled by predictors. Implications for theory and practice: The suggested techniques open novel possibilities of multiple-criteria decisions helping to researchers and managers to discover useful features of priority behavior due to the demographic, socio-economic, or technical properties of the compared alternatives, and to find optimal solutions for individual customers.
本文的目的是:将AHP的能力扩展到新的领域,从解释著名的双包络悖论到寻找作为辅助变量函数的优先级。独创性:提出的创新和有利的方法允许通过指数或柯布-道格拉斯生产函数的回归建模来找到非恒定优先级。研究方法:将比例尺度转化为与乘法效用函数相对应的加性尺度或对数尺度,为多准则决策开辟了新的可能性。主要发现:解决了双包络问题,优先向量通过辅助变量表示为函数,预测者对偏好进行了预测和描述。对理论和实践的启示:建议的技术为多标准决策提供了新的可能性,帮助研究人员和管理人员发现由于比较方案的人口、社会经济或技术特性而导致的优先行为的有用特征,并为个人客户找到最佳解决方案。

Paper aims: This work presents a multi-objective method based on goal programming associated with non-Archimedean infinitesimal (NAI) (Improved Weighted Goal Programming method, input-oriented IWGP-MCDEA-BCC). Originality: The MCDEA is applied for the first time in a large agricultural company (over 11 hectares). A new method is proposed which consists of an improvement on input-oriented WGP-MCDEA-BCC approaches. Research method: The performance of the proposed method was compared to the classic Data Envelopment Analysis and the Weighted sum Goal Programming methods. The case study comprises an agricultural company located in the São Francisco Valley (Brazil). Main findings: The proposed method can help decision makers to improve efficiency in the production of different types of fruits. Implications for theory and practice: The proposed model is capable of overcoming the deficiencies associated with classical DEA and allows the company to identify effective ways to increase productivity by reducing input costs.

Paper aims : This article presents the development and results of research carried out to know the modus agendi of a Regional Triple Helix and measure the intensity of the presence of a set of factors proposed as determinants of its existence and consolidation. Originality : This is an unprecedented contribution to research in TH, as it investigates how much an established regional reality matches the pattern of a modus agendi and a set of determining factors of its existence and consolidation. Research method : The inductive basic research method was adopted, with qualitative and quantitative approach, exploratory and descriptive objective and field research, applying the e-Delphi method. Main findings : A high degree of misalignment of perceptions was identified among respondents and the existence of a Triple Helix that is still consolidating. Implications for theory and practice : The relevance of this article is corroborated by the unprecedented application of the calculation of three statistical indicators (CVI-h; CV; IR) in the e-Delphi method. Another important contribution of this research lies in the fact that it investigates the level of alignment of the modus agendi of a TH, with a set of determinant factors that indicate the existence and consolidation of this development.
论文目的:本文介绍了研究的发展和结果,以了解区域三螺旋的模式议程,并测量作为其存在和巩固的决定因素的一组因素的存在强度。原创性:这是对TH研究的一个前所未有的贡献,因为它调查了一个既定的区域现实在多大程度上与议程模式的模式相匹配,以及其存在和巩固的一系列决定因素。研究方法:采用归纳基础研究方法,采用定性与定量相结合、探索性与描述性的客观调查和实地调查相结合,采用e-Delphi法。主要发现:在受访者中发现了高度的观念偏差,三螺旋结构的存在仍在巩固。对理论和实践的影响:本文的相关性得到了三个统计指标(CVI-h;简历;e-Delphi法中的IR)。本研究的另一个重要贡献在于,它调查了TH模式议程的对齐水平,以及表明这一发展存在和巩固的一组决定因素。

Paper aims: This paper presents the results of technological analysis on wind energy based on patent documents classified with code F03D – “Wind Motors.” Originality: Despite several studies on wind energy, this paper follows a different approach, presenting an overview that brings together technical and market information through social network analysis methods. Research method: The study covered data from 55,223 documents filed in the principal patent offices of the world, obtained from the Derwent Innovations Index. The publications were organized and analyzed through correlation and technology transfer networks. Main findings: General Electric (GE) and European companies have dominated the wind energy industry. However, in the last years, companies from emerging countries are also penetrating and becoming major players. Emphasis can be given to China, which has a deposit pattern detached from the rest of the world. Implications for theory and practice: This study indicates that these companies became important turbine manufacturers and started to invest in developing new technologies and seek patent protection. Companies from emerging countries are new entrants, and their performance is still restricted to few markets compared to traditional companies.
论文目的:本文根据分类代码为F03D -“风力发电机”的专利文献,对风能进行了技术分析。原创性:尽管对风能进行了几项研究,但本文采用了不同的方法,通过社会网络分析方法,将技术和市场信息结合在一起,给出了一个概述。研究方法:该研究涵盖了世界主要专利局提交的55223份文件的数据,这些数据来自德文特创新指数。通过相关和技术转让网络对出版物进行组织和分析。主要发现:通用电气(GE)和欧洲公司主导了风能行业。然而,在过去的几年里,来自新兴国家的公司也在渗透并成为主要参与者。我们可以把重点放在中国,因为中国的稀土储备模式与世界其他地区截然不同。理论与实践启示:本研究表明,这些公司已成为重要的涡轮机制造商,并开始投资开发新技术并寻求专利保护。新兴国家的公司是新进入者,与传统公司相比,它们的业绩仍局限于少数几个市场。

Paper aims: Work design is being constantly transformed by technology and requirements for polyvalent workers piloting the work system instead of operating it. This paper investigates self-management teams’ implementation and its effects on performance. A Brazilian cosmetics company case study of team development was used as a guidance for this investigation. Originality: Consistent connection between team development theory and practice, exploring sociotechnical approach and empowerment best practices. Research method: Boxplot analysis is performed over team building stages along with One-way Variance Analysis to test average performance differences among stages’ transitions. Tukey test was sequentially applied to identify its statistic differences in pairs. Descriptive analysis and Analysis of Means are complementarily applied for shop-floor accidents performance assessment. Main findings: Team development reached the expected performance over team stages. Forming to storming, though, was the only transition with no performance average gains. Storming to norming was the highest improvement, which meets sociotechnical principles. Moreover, mean of accidents was inferior at performing stage comparing to the overall mean of accidents during the whole project, highlighting additional shop-floor safety improvements enhanced by the new work design. Implications for theory and practice: This paper is restricted to a single sociotechnical environment. Therefore, generic conclusions imply further investigation.
论文目的:工作设计正不断被技术和需求所改变,多价工人正在试行而不是操作工作系统。本文研究了自我管理团队的实施及其对绩效的影响。一个巴西化妆品公司的团队发展案例研究被用作本调查的指导。独创性:团队发展理论与实践之间的一致联系,探索社会技术方法和授权最佳实践。研究方法:对团队建设阶段进行箱线图分析,并进行单向方差分析,检验各阶段过渡之间的平均绩效差异。序贯Tukey检验确定其对间的统计差异。描述分析法和方法分析法在车间事故绩效评价中相辅相成。主要发现:团队开发在团队阶段达到了预期的绩效。然而,形成到风暴是唯一一个没有平均性能提升的转变。风暴到规范是最高的改进,它符合社会技术原则。此外,与整个项目期间的总体事故平均值相比,执行阶段的事故平均值较低,突出了新工作设计增强的额外车间安全改进。对理论和实践的启示:本文仅限于单一的社会技术环境。因此,一般性结论意味着进一步的研究。

Paper aims: the paper aims to demonstrate the advantages of several modifications of combinatorial method of expert judgment aggregation in AHP. Modifications are based on 1) weighting of spanning trees; 2) sorting of spanning trees by graph diameter during aggregation. Originality: Both the method and its modifications are developed and improved by the authors. We propose to 1) weight spanning trees, based on quality of respective expert estimates, and 2) sort them by diameter in order to reduce the impact of expert errors and the method’s computational complexity. Research method: we focus on theoretical and empirical studies of several modifications of combinatorial method of aggregation of expert judgments within AHP. Main findings: modified combinatorial method has several conceptual advantages over ordinary method. It is also less sensitive to perturbations of initial data. Additionally, selection of spanning trees with smaller diameters allows us to reduce computational complexity of the method and minimize the impact of expert errors. Implications for theory and practice: Combinatorial method is a universal instrument of expert judgment aggregation, applicable to additive/multiplicative, complete/incomplete, individual/group pair-wise comparisons, provided in different scales. It is used in the original strategic planning technology, which has recently found several important applications.

Paper aims: This study aims to analyze the travel behaviors changings and the emissions reduction of CO2, CO, NOx and Particulate Matter (PM) promoted by the bicycle sharing system in the city of Rio de Janeiro. Originality: The bicycle sharing systems have been experiencing rapid development in recent years, however, few empirical studies explore comprehensively the externalities of bicycle sharing, seeking to quantify the impacts of this travel system type on urban transport. Research method: The research method used a modal distribution model calibrated with stated preference interviews and travel data provided by Tembici company. Main findings: Results indicated a reduction in 2018 CO2 emissions compared to the existing system in 2014, not only because of the increase in the bicycle sharing system offer, but also due to a higher transfer rates from motorized transport to bicycle, particularly those originated from public transport and Transportation Network Company (TNC) services. Implications for theory and practice: Results reveal the bicycle sharing in the city of Rio de Janeiro should be understood as a part of a process of adopting multimodality, with effective reductions achieved by the incentive to change passenger’s travel behavior.
论文目的:本研究旨在分析巴西里约热内卢市共享单车系统对出行行为的改变以及对二氧化碳、一氧化碳、氮氧化物和颗粒物(PM)排放量的减少。独创性:近年来,共享单车系统发展迅速,但很少有实证研究全面探讨共享单车的外部性,试图量化这种出行系统类型对城市交通的影响。研究方法:采用Tembici公司提供的偏好访谈和旅行数据校准的模态分布模型。结果表明,与2014年现有系统相比,2018年的二氧化碳排放量有所减少,这不仅是因为自行车共享系统提供的增加,还因为从机动交通工具到自行车的转换率更高,特别是那些来自公共交通和交通网络公司(TNC)服务的转换率。对理论和实践的启示:研究结果表明,巴西里约热内卢市的自行车共享应被理解为采用多模式的过程的一部分,通过激励乘客改变出行行为来有效减少。

Implications for theory and practice: Results reveal the bicycle sharing in the city of Rio de Janeiro should be understood as a part of a process of adopting multimodality, with effective reductions achieved by the incentive to change passenger’s travel behavior.","PeriodicalId":34960,"journal":{"name":"Production","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67575604","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}

SP, Brasil *sacomanoneto@gmail.com Abstract Paper aims: This paper aims to understand how the social skill of managers influence the diffusion of operational capabilities in food and auto parts manufacturing networks. Originality: There are taken-for-granted beliefs that its diffusion is based on replicating or transferring resources and practices from one site to another. This study is one of the first ones to discuss operational capability and socially skilled actors. Research method: Two polar cases were analyzed through the Strategic Action Fields perspective based on a qualitative perspective and 17 in-depth interviews. Main findings: Results demonstrate that diffusion of capability among various actors in subsidiaries will depend on a series of multidimensional factors that influence this process as the stability, state, and relationship between fields. Moreover, members tend to adopt a logic (perception of the world) that reflects the point of view of the group, and from this, the actors construct their narratives, recognize the legitimacy and justify their actions. Implications for theory and practice: These perspectives have scarcely been explored in Operations management till today and shall open a new dialogue between Operations Strategy and Organization Studies. It offers practical guidance for diffusing and
摘要论文目的:本文旨在了解管理者的社交技能如何影响食品和汽车零部件制造网络中运营能力的扩散。独创性:有一种想当然的信念,认为它的传播是基于复制或将资源和实践从一个地点转移到另一个地点。本研究是第一个探讨行动能力与社会技能演员关系的研究。研究方法:在定性视角和17次深度访谈的基础上,通过战略行动领域视角对两个极端案例进行分析。主要发现:研究结果表明,子公司中不同行为者之间的能力扩散取决于一系列多维因素,如领域之间的稳定性、状态和关系。此外,成员倾向于采用一种反映群体观点的逻辑(对世界的感知),行动者以此构建自己的叙事,承认其合法性,并为自己的行为辩护。对理论和实践的启示:直到今天,这些观点在运营管理中还很少被探索,并将在运营战略和组织研究之间开启新的对话。它为扩散和扩散提供了实用的指导
