Goal: This study aims to review and classify the main methods of criteria weights definition. Design / Methodology / Approach: From a systematized search were articles selected and analyzed, covering a timeline between 1949 and 2020. Results: Fifty sex methods were identified and discussed. Most (49) are subjective, eleven are objectives and three are hybrids. Considering the aggregation procedure, 33 are compensatory and 23 are non-compensatory. Most of the methods are for a single decision maker and just eleven are multidecision makers. The main contributions are published on European Journal of Operational Research journal. Limitations of the investigation: This work does not make a thorough technical analysis of the presented methods and it is not a notebook to indicate to researchers which method is the best for each type of situation. Some methods may not have been included. Practical implications: The selection and the definition of criteria weight is a fundamental question in the Multicriteria Decision Aid (MDCA) approach. The MCDA has a wide application on operation and production management. The diversity of published papers on this subject, the comprehension of its characteristics and applicability is a complex task for researchers and professionals who demand these techniques. Originality / Value: This work contributes to identify the state of the art of the models applied to the weight of the criteria, as well as to identify its characteristics and functionality regarding MCDA modeling.

Goal: This study aimed to identify and describe garment’s post-consumer textile waste management practices and to analyse them according to environmental, economic and social criteria in the circular economy context. Design / Methodology / Approach: A literature review was conducted to identify, collect and organize practices from garment’s post-consumer textile waste management and the environmental, economic and social criteria taken into account for the analysis of such practices in a circular context. Results: There were eleven collection practices, three sorting practices, five reuse practices, and six recycling practices. Additionally, even circularity is presented as a new solution to environmental problems, those practices identified in literature are pulled mainly downstream, promoting shortterm waste management approaches, while the initial production chain’s links continue to extract and use several non-renewable resources from the excessive way. Limitations of the investigation: The limitations of a literature review of this nature is the complete reliance on the defined strings to search the previously published research and the adopted procedures to select and evaluate these studies (data base, search period, exclusion criteria) Practical implications: For researchers and garment’s industry professionals, the identified practices should provide new solutions that could be tested in the current post-consumer textile waste management model. Moreover, this research allowed understanding the way those postconsumer textile waste management’s practices are interpreted under a circular context. Originality/Value: there is almost no detailed study of post-consumer textile waste management’s practices. Furthermore, it is very rare to find those textile waste management practices related in a circular context.

Goal: Today, digital technologies have significant effects on supply chains as companies explore and exploit their opportunities. Digital supply chains promise advantages over traditional ones. A maturity model is a helpful tool to assess the current state of digitalization in supply chains and to guide companies towards implementation. The main goal of this paper is to investigate existing maturity models for digital supply chains and propose possibilities for future research. Design / Methodology / Approach: A structured literature review is conducted to identify relevant maturity models. Those are analyzed regarding their type and emphasis on a specific supply chain function or certain digitalization dimension. Results: Twenty-eight maturity models are identified. Each of them focuses on a particular supply chain function or a specific digital technology. A focus on manufacturing (Industry 4.0) and, consequently, a lack of research regarding other aspects of the supply chain digitalization becomes evident. Moreover, most papers lack coverage of all digitalization dimensions. Besides, more rigorous research regarding the quality of the maturity models, their evaluation, and application is needed. Limitations of the investigation: The conducted review is limited to two databases (Scopus and Web of Science). Two researchers conducted the analysis, which might lead to some bias. Furthermore, the analysis could be broadened and performed more in-depth to derive further insights. Practical implications: Practitioners might use the presented overview of existing maturity models to identify a well-developed one that fits their desired application scenario. Originality / Value: This paper provides suggestions for future research and highlights interesting and relevant topics to investigate.
目标:今天，随着企业探索和利用机会，数字技术对供应链产生了重大影响。数字供应链比传统供应链更有优势。成熟度模型是评估供应链数字化现状并指导企业实施的有用工具。本文的主要目的是研究现有的数字供应链成熟度模型，并提出未来研究的可能性。设计/方法/途径:进行结构化的文献综述，以确定相关的成熟度模型。根据其类型和对特定供应链功能或某些数字化维度的强调进行分析。结果:确定了28个成熟度模型。他们每个人都专注于一个特定的供应链功能或一个特定的数字技术。关注制造业(工业4.0)，因此缺乏对供应链数字化其他方面的研究变得明显。此外，大多数论文缺乏对所有数字化维度的覆盖。此外，还需要对成熟度模型的质量、评价和应用进行更严格的研究。调查的局限性:所进行的综述仅限于两个数据库(Scopus和Web of Science)。两名研究人员进行了分析，这可能会导致一些偏见。此外，可以扩大分析范围并进行更深入的分析，以获得进一步的见解。实际含义:从业者可能会使用所提供的现有成熟度模型的概述来确定适合他们期望的应用程序场景的开发良好的模型。原创性/价值:本文为未来的研究提供了建议，并突出了有趣和相关的研究主题。

Goal: The goal of this paper is to investigate 15 Brazilian companies, which execute S&OP cycles periodically, in order to characterize the processes implemented and discuss challenges and improvement opportunities. Design / Methodology / Approach: Initially, a multiple-case study approach is applied embracing 15 Brazilian companies. Then, a survey is conducted in the same organizations to deepen the investigation. Two recognized S&OP frameworks from the literature are used to structure the research. Results: Some of the main research findings include: some companies consider “Data Gathering” a normal task and no longer a S&OP cycle step; some organizations include a new step one named “Portfolio Management”, preceding “Demand Planning” to leverage step two’s outcomes; there are improvement opportunities identified in “Pre-meeting” and “Executive Meeting” steps regarding capacity to simulate different scenarios from a financial perspective; and most of the studied companies do not adopt a S&OP software facing limitations to manage information and perform what-if analysis. Limitations of the investigation: Only companies located in Brazil are investigated. Practical implications: The study provides useful information for practitioners on the characterization of the S&OP process, implementation challenges, and improvement opportunities. Originality / Value: The paper applies different research methods (multiple-case study and survey) and two recognized frameworks from the literature in the study of the S&OP process performed by 15 companies, providing a broad characterization of the processes implemented and valuable findings about challenges and improvement opportunities. Although all the researched companies are Brazilian, evidences indicate the results are generalizable.

Goal: Although card-based systems are a mature topic in literature, studies have focused mainly on how to optimize parameter of each system. The influential of human factors in the implementation of those systems have rarely been evaluated. Therefore, this study aims to understand what are the critical soft factors for a successful card-based systems implementation. Design / Methodology / Approach: A multi-method study is used in this research, combining systematic literature review, longitudinal case study, content analysis, interviews with experts and validations with two different groups. Results: The paper proposes a list of 15 soft factors critical to a successful implementation of cardbased systems categorized in a “house framework” according to the level of analysis each factor is included. Limitations of the investigation: A single case study, although longitudinal, was conducted to proposed the list of factors. Therefore, further studies should be conducted to adapt the list to other organizations and contexts. Practical implications: Following the proposed list of factors, managers can increase the success in implementing a card-based system in their organizations. Originality / Value: This study combines different research methods in a unique way, since in the researchers' view, an individual method was not sufficient to answer the proposed research question. Moreover, the case study reported a failure implementation of a card-based system, a rare addition to literature which mainly presented success cases.

Goal: Industry 4.0 has the main purpose of turning the company into an agile organization and adapting continuously to the market's dynamicity. Thus, to reach this target, the business should be aware of its current readiness level and establish digital strategies to reach higher levels. This research aims to explore how improvements in industry 4.0 can improve companies' business processes. Design / Methodology / Approach: The present study is action research that initially identified the most suitable maturity model in Industry 4.0 in the scientific and practitioner literature. Furthermore, the chosen model was applied to a beverage manufacturer to evaluate its current maturity level. Some Industry 4.0 improvements were implemented on the warehouse as part of the company's digital strategy into which it was integrated the inventory management system with new digital solutions. Finally, interviews were conducted, and data was gathered from company indicators. Results: The action research’s conduct revealed its current status and how storage management contributed to its digital transformation process. A phenomenon of islands of improvement is discussed at the end. Limitations of the investigation: Our main limitation is our case study approach. Additionally, more interviews crossing functional areas could bring additional elements about the perception of improvements that each functional group had at the implementation process. Practical implications: The case study suggests that maturity models' applications can generate the phenomena of islands of improvements. Managers must take this situation into account to plan digital transformation in the whole company. Originality / Value: The phenomena of the island of improvement is suggested to be a side effect of implementing industry 4.0 based on maturity models.

Goal: This study seeks to examine project success in relation to project managers’ factors. Pertaining to research questions, we highlighted: “do project manager’s technical, conceptual, political and human skills are significantly related to project success?, and does project manager’s age play a significant role in achieving project success? Design / Methodology / Approach: This research employed a quantitative research method using survey questionnaires to collect data from 400 project managers working in five well-known construction companies in Cairo, Egypt. Descriptive statistics using Relative Importance Index (RII) were employed to rank the dimensions of project manager’s skills: conceptual, technical, human and political skills; and project success dimensions: cost, schedule and quality. Multiple regression analysis was used to identify the impact of project managers’ skills on project success while simple linear regression was used to examine the relationship between project manager’s age and project success Results: The results of RII revealed that project managers maintain a competitive level of technical, conceptual, political and human skills, and emphasize on specific aspects of cost, schedule, and quality dimensions of project success. The regression analysis revealed that 49.2% of the explained variation in project success can be accounted for technical, political, human and conceptual skills at coefficient of determination values of 0.611, 0.506, 0.431 and 0.407 respectively while the project manager’s age had no association with project success with a P value 0.694 at alpha level of 0.05. Limitations of the investigation: Generalizing research findings might be challenged because sample size was randomly selected due lack of identifying the exact size target population. Practical implications: The managerial implication of this study lies in the need for construction companies not to consider project manager’s age as a significant factor for project success, instead they need to ensure that project managers possess a competitive level of conceptual, technical, political and human skills. Originality / Value: Pertaining to contribution to academia, this research argues that project success subject to a set of comprehensive set of project managerial skills namely conceptual, technical, political and human. Further, it is essential to distinguish between project manager’s age and experience and not to consider project manager’s age as a determinant of a project success.

目的:本研究旨在考察项目成功与项目经理因素的关系。关于研究问题，我们强调了:“项目经理的技术、概念、政治和人际关系技能是否与项目成功有重大关系?”项目经理的年龄是否对项目的成功起到重要作用?设计/方法/方法:本研究采用定量研究方法，采用问卷调查法，对埃及开罗五家知名建筑公司的400名项目经理进行数据收集。采用相对重要性指数(RII)进行描述性统计，对项目经理的技能维度进行排名:概念、技术、人际和政治技能;项目成功的维度:成本、进度和质量。多元回归分析用于确定项目经理技能对项目成功的影响，而简单线性回归用于检验项目经理年龄与项目成功之间的关系。结果:RII的结果显示，项目经理在技术、概念、政治和人际技能方面保持竞争水平，并强调项目成功的成本、进度和质量维度的特定方面。回归分析表明，49.2%的项目成功变异可以解释为技术、政治、人际和概念技能，决定系数分别为0.611、0.506、0.431和0.407，而项目经理的年龄与项目成功没有关联，P值为0.694，α水平为0.05。调查的局限性:由于样本大小是随机选择的，缺乏确定目标人群的确切大小，因此概括研究结果可能受到挑战。实际意义:本研究的管理意义在于建筑公司不需要将项目经理的年龄视为项目成功的重要因素，相反，他们需要确保项目经理拥有具有竞争力的概念，技术，政治和人际技能水平。原创性/价值:关于对学术界的贡献，本研究认为项目的成功取决于一系列综合的项目管理技能，即概念、技术、政治和人力。此外，区分项目经理的年龄和经验，而不是将项目经理的年龄视为项目成功的决定因素，这是至关重要的。关键词:项目经理技能;项目经理年龄;项目的成功;建筑行业。许多组织依靠项目来运行运营并维持其业务成功。《项目经理的技能和年龄对项目成功的影响》，《巴西运营与生产管理杂志》，Vol. 18, No. 4, e2021950, 2021 /16客户。建设企业在经营活动中，建设住宅、公寓、公寓、别墅、学校、医院、桥梁、机场、商店、商场、道路等，都离不开项目管理。在处理具体的建筑项目时，建筑公司需要指派具有相关技能的项目经理，以确保项目的成功。研究承认项目经理的技能在实现项目成功中的重要作用(Hwang and Ng, 2013;Sunindijo, 2015)。建筑业是埃及的基础产业之一，对经济发展和创造就业机会有着显著的影响。埃及政府强调基础设施和建设作为金融稳定和城市发展的主要驱动力的重要作用。尽管新冠肺炎疫情对建筑业产生了负面影响，但随着该国人口的持续增长，对基础设施、住房和基础设施的需求保持稳定。根据牛津商业集团(Oxford Business Group)的一份报告(2020)，到2052年，在城市化和政府支持的不断增长趋势的推动下，埃及建筑业有望实现长期增长，埃及的城市面积将从7%增加到14%。根据最近的惠誉评级报告，埃及建筑业将在未来十年继续保持强势地位，2020-2024年期间的年增长率为9% (Refaat, 2020)。此外，Refaat(2020)报告称，目前埃及建筑业的价值约为250亿美元，预计到2029年将达到890亿美元以上，约占中东和北非地区建筑业价值的30%。研究人员和专业人士认为，项目经理是建设项目成功的一个非常重要的因素，并在建设项目的每个阶段产生影响，如Ali和Chileshe(2009)所认为的那样。
