abstract: The heterogeneity and the volume of solid urban waste generated daily cause difficulties in their management, which causes environmental impacts, health and public safety problems. Among all waste management activities, collection is one of the most relevant from an occupational point of view because employees are subject to physical, chemical, biological, ergonomic risks as well as suffering accident. This article aims to instruct companies to apply multidisciplinary management tools that conciliate and serve as a basis for decision making related to environmental and occupational safety management. Therefore, the Ad Hoc Environmental Impact Assessment techniques and the RMT Risk Management Tool were used to identify the environmental impacts generated and the risks to which employees in the urban solid waste collection sector are exposed. It happened through the collection of operational, environmental information and work safety data, in 2017, of companies operating in 7 (seven) municipalities in the state of Rio Grande do Sul. The Ad Hoc report showed that the environmental aspects of surface water, groundwater, soil, odor and air pollution, generate negative and irreversible environmental impacts. Furthermore, the analysis of accidents at work, the identification of the major agents that cause accidents at work and the nature of injuries, showed their high frequency and severity. In total 60 accidents were recorded and all occurred with garbage collectors. Among these, 13 had as causative agents “glassware, fiberglass, blade, except vial, bottle” and the most recurrent types of injuries were “excoriation and abrasion (superficial wound)” and “by cutting, laceration, blunt wound, puncture (open wound)”, both with 22% of occurrence, which generate work leave. Furthermore, the elaboration of Action Plans and application of the 5W2H Quality Management tool proved to be excellent tools for assessments regarding the minimization of environmental impacts and the control of accidents at work.

Abstract: This paper investigates the existence of uncertainties in different wind power commercialization contracts in Brazil and their correlation with the Real Options associated with unmitigated risks in the Back up Energy and New Energy contracts. From a documentary review of existing contracts from 2009 to 2018, it was found that the Real Options on New Energy contracts are more susceptible to market uncertainties related to energy price in the short-term market. The Real Options associated with risks not mitigated in Back up Energy contracts are more linked to uncertainties regarding the power generation efficiency and the project plant expansion capacity in order to generate the anticipation of its supply.

Abstract: Knowledge management is a key resource for enabling projects and organizations to address the current challenges of competitive environment. This article aims to investigate the central themes of knowledge management in the project context, exploring the relationship between knowledge management and project performance. For this purpose, a literature review was carried out, adopting bibliometric analysis, codification and content analysis. The search and sampling process was conducted in the Web of Knowledge (Web of Science Core Collection) database. First, the results identified the main strategies to deal with tacit and explicit knowledge, which are experts’ knowledge acquisition and project documentation through coded forms, respectively. Both types of knowledge, tacit and explicit, are strongly related to two of the project success dimensions: GP efficiency, and success of the product/service. The literature pointed out that organizations recognize the importance of knowledge management but they still face many barriers to implement it in practice. The publications allowed verifying that the subjects are still little related, making it a challenging field for future studies.
摘要:知识管理是项目和组织应对当前竞争环境挑战的关键资源。本文旨在探讨项目背景下知识管理的核心主题，探讨知识管理与项目绩效之间的关系。为此，本文采用文献计量学分析、编撰法和内容分析法进行文献综述。在Web of Knowledge (Web of Science Core Collection)数据库中进行检索和抽样。首先，研究结果确定了处理隐性知识和显性知识的主要策略，分别是通过编码形式获取专家知识和编制项目文档。这两种类型的知识，无论是隐性的还是显性的，都与项目成功的两个维度密切相关:GP效率和产品/服务的成功。文献指出，组织认识到知识管理的重要性，但在实践中实施知识管理仍面临许多障碍。这些出版物允许验证这些主题仍然很少相关，使其成为未来研究的一个具有挑战性的领域。

abstract: The purpose of the research was to determine the sequencing of the production of n jobs in m operations in a small footwear company in an environment of flow shop machine characteristics, which optimizes the total time of completion of the job in the production system (Makespan). We used heuristic algorithms that were applied through Lekin and WinQSB softwares, and for the optimization algorithm we designed a mathematical model that was solved by Juliabox software. Results show that the integer linear programming and local search minimize the makespan with 3807 minutes, and different production sequences for each algorithm, which consider permutation, which improves the traditional way of programming the production in 97 minutes, however, the optimization presents better results in the performance measures of average waiting time, average time of flow, and average job in process. Application of heuristic algorithms proves to be simple and fast, but the mathematical model of optimization designed and encoded in the software is a flexible and valuable tool for decision making in production programming, which could be applied in other footwear companies, and in other productive sectors whose companies have the same characteristics of the case study, reducing costs and improving delivery times.

Abstract: Theory of Constraints (TOC) states that every system has a single constraint that limits its performance, on which improvement efforts should be concentrated. This paper compared, through computer simulation, several methods of identifying the capacity-constrained resource in the perspective of a process of continuous improvement. Six make-to-stock (MTS) production line configurations managed by the Simplified Drum-Buffer-Rope (S-DBR) system were simulated, in which six improvement methods were applied, three of them based on the TOC literature, and their performance measured and compared in terms of cycle time and order fill rate. The results showed that, in balanced systems, improvements spread over all resources allowed better results, because, in this case, it is necessary to improve everything to benefit the overall performance. In unbalanced environments, on the other hand, the three methods recommended by TOC, which recommend efforts concentrated on the weakest point of the system, achieved superior performance, with emphasis on the strategy based on the level of utilization. In addition to advancing the frontiers of knowledge in continuous improvement and TOC, the research results show that managers should focus their attention on the resource with the highest degree of utilization to get better and faster performance gains.

Abstract Sensing networks provide nowadays massive amounts of data that in many applications provide information about curves, surfaces and vary over a continuum, usually time, and thus, can be suitably modelled as functional data. Their proper modelling by means of functional data analysis approaches naturally addresses new challenges also arising in the statistical process monitoring (SPM). Motivated by an industrial application, the objective of the present paper is to provide the reader with a very transparent set of steps for the SPM of functional data in real-world case studies: i) identifying a finite dimensional model for the functional data, based on functional principal component analysis; ii) estimating the unknown parameters; iii) designing control charts on the estimated parameters, in a nonparametric framework. The proposed SPM procedure is applied to a real-case study from the maritime field in monitoring CO2 emissions from real navigation data of a roll-on/roll-off passenger cruise ship, i.e., a ship designed to carry both passengers and wheeled vehicles that are driven on and off the ship on their own wheels. We show different scenarios highlighting clear and interpretable indications that can be extracted from the data set and support the detection of anomalous voyages.

Abstract: The management of waste from health services is considered an extremely controversial topic and widely discussed because it is mainly about contaminated materials. This study aims to analyze the waste management of health services in hospitals in a southern region of Brazil, identifying the final disposal processes, in accordance with the National Solid Waste Policy, describing the management and practices in each link of the final destination chains and estimation of the volume of post-consumer waste generated. For this, it was necessary to describe the management and practices in each link of the chains, estimate the volume of waste generated, identify the reverse logistics chains and the final destination of the post-consumer waste from the health services. In addition to evaluating the feasibility of reusing hospital waste, taking into account the technical standards and legislation present in the National Solid Waste Policy and in organizations such as the National Agency for Health Surveillance, the Brazilian Association of Technical Standards, the National Council of the Environment and the National Nuclear Energy Commission. The National Solid Waste Policy brought an information framework already contained in other norms and resolutions in force, before its publications, determining the objectives that have not yet been fully met in the investigated region.

Abstract: Because of their vital role and the need to protect the patient information, interest in information security in Healthcare Supply Chains (HSCs) is growing. This study analyzes how decisions related to information security practices in HSCs contribute to protecting patient information. Eleven semi-structured interviews were performed. The interviewees were managers from Brazilian HSC organizations. Four dimensions and 14 variables identified in a literature review were used to perform categorical content analysis. The findings suggest organizations, while aware of their critical information and internal processes, lack the necessary metrics to measure the impacts of possible failures. It seems organizations tend to invest in standard security measures, while apparently ignoring the specificity and complexity of information in HSCs.

Abstract: The management of Waste Electrical and Electronic Equipment (WEEE) or electronic waste (e-garbage or e-waste) has become a major concern for urban communities due to the large volumes of waste generated, from the end of the 20th century. In this context, this work seeks to gather information for the implementation of a Reverse Logistics system that is comprehensive and regular for WEEE in the city of Campos dos Goytacazes – RJ. The behavior of the consumer was analyzed using a version adapted and inspired by the AHP Method, regarding to the most relevant considerations when disposing of WEEE (cell phones, computers and tablets). The data needed for this work were collected through the application of a questionnaire with open and closed questions to a sample, random and representative of citizens, in the city under study. It was noticed that the results found would support the decisions to be taken in the design of an efficient management system for WEEE. It is also worth mentioning that this research was carried out under the current considerations of sustainability according to what determines the Brazilian legislation on Solid Waste and can be intended as a prototype to be adapted to the reality of other cities in the country.

Abstract The purpose of this research is to analyze the adherence of the NBR ISO 14001 standard to the Brazilian Institute of Corporate Governance Code of Best Corporate Governance Practices. The perspective established in the research interprets the existence of synergy between management supported by the Environmental Management Systems standard and the Code of Best Corporate Governance Practices. The research analyzed the contents of 177 environmental audit reports, performed by a certification company, which involved a set of 139 companies certified by NBR ISO 14001. It then related the requirements of the environmental management system with the elements present in the IBGC code. It identified the adherence to several requirements in common between the two systems analyzed, thus indicating the adequacy of establishing synergy in actions, and in the information held by both, providing benefits to the organization. Environmental auditing data indicate that companies have more difficult-to-handle items related to operational control, emergency preparedness and assessment of compliance with legal and other requirements.

摘要本研究的目的是分析NBR ISO 14001标准对巴西公司治理协会最佳公司治理实践准则的依从性。研究建立的视角解释了环境管理体系标准与最佳公司治理实践准则支持的管理之间存在协同作用。该研究分析了一家认证公司执行的177份环境审计报告的内容，其中涉及139家通过NBR ISO 14001认证的公司。然后将环境管理体系的要求与IBGC规范中的要素联系起来。它确定了所分析的两个系统之间对若干共同要求的遵守，从而表明在行动和双方掌握的信息中建立协同作用的适当性，从而为组织提供利益。环境审计数据表明，公司在业务控制、应急准备和评估遵守法律和其他要求方面有更多难以处理的项目。这在公司治理的背景下是重要的信息，因为它表明了为了保证组织的长期性必须消除的潜在风险。

The perspective established in the research interprets the existence of synergy between management supported by the Environmental Management Systems standard and the Code of Best Corporate Governance Practices. The research analyzed the contents of 177 environmental audit reports, performed by a certification company, which involved a set of 139 companies certified by NBR ISO 14001. It then related the requirements of the environmental management system with the elements present in the IBGC code. It identified the adherence to several requirements in common between the two systems analyzed, thus indicating the adequacy of establishing synergy in actions, and in the information held by both, providing benefits to the organization. Environmental auditing data indicate that companies have more difficult-to-handle items related to operational control, emergency preparedness and assessment of compliance with legal and other requirements. This is important information in the context of corporate governance, since it indicates potential risks that must be eliminated in order to guarantee the perenniality of the organization.","PeriodicalId":35415,"journal":{"name":"Gestao e Producao","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67128509","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}
