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.","PeriodicalId":54139,"journal":{"name":"Brazilian Journal of Operations & Production Management","volume":"28 1","pages":""},"PeriodicalIF":1.1,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87087342","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}

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.","PeriodicalId":54139,"journal":{"name":"Brazilian Journal of Operations & Production Management","volume":"7 1","pages":""},"PeriodicalIF":1.1,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86523917","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}

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.

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.","PeriodicalId":54139,"journal":{"name":"Brazilian Journal of Operations & Production Management","volume":"55 1","pages":""},"PeriodicalIF":1.1,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85070206","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}

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.

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.
