The Supply Chain has undergone major transformations due to the need to implement new Industry 4.0 technologies, such as Internet of Things, Big Data, Cyber-Physical Systems and Cloud Computing. Thanks to these technologies, as well as to their subsystems and components, full integration of the supply chain is becoming possible. However, it is observed that the real impacts of Industry 4.0 technologies, rather positive or negative, are not yet totally clear and identified. This paper aims to identify and present an analysis of the challenges and obstacles that Industry 4.0 technologies may cause in the Supply Chain. For this, the most relevant papers on the topic were selected and analyzed through a systematic literature review. Twenty challenges grouped into four macrogroups were identified: (1) technical challenges, (2) financial, environmental and legal challenges, (3) technological challenges, and (4) sociocultural challenges. It should be noted that these challenges require greater attention and more in-depth studies on the part of the academy to support industry in order to mitigate them and thus allow better use of the available technological resources and optimize the performance of Supply Chain operations.

Companies adopt sustainable practices in order to improve the economic, environmental and social performance of their operations. This fact does not occur with the same intensity in maintenance operations. By adopting sustainable practices during the implementation of maintenance strategies, there will be mitigation of industrial maintenance impacts on sustainability. However, there are few studies on the integration of sustainability in maintenance activities and few companies adopt sustainable maintenance due to lack of knowledge of the subject and its benefits. This paper aims to show how the concepts of sustainability are being inserted in the maintenance strategies. For this purpose, a literature review and a systematic literature review were performed. It was verified that the concepts of sustainability are integrated into maintenance strategies by means of sustainable criteria, with emphasis on lost production cost, spare parts cost and expenditures associated with energy consumption and greenhouse gas emissions (economic dimension), on pollutant emission due to energy consumption during machining/manufacturing (environmental dimension) and on health and safety at work (social dimension). This paper contributes to the dissemination of the theme and motivates the companies to implement sustainable maintenance.can serve as inspiration for the development of new studies, both for academics and professionals in the maintenance and sustainability areas of the industry.

Paper aims: The objective of this paper is to evaluate the economic, social, and environmental impacts of logistics activities of a dairy producer located in Brazil. Originality:The main contribution is to apply a quantitative approach to assessing sustainable logistics in the milk supply chain, serving as a basis for future work on this theme. Research method:A single case study of a regional producer of dairy products in Brazil is carried out in this research. A sustainable logistics evaluation model was used that quantitatively measures the impact of transportation, storage (including inventory management and material handling activities), packaging, and acquisition activities in the economic, environmental, and social dimensions.Main findings: It illustrates the challenge that a Small Medium Enterprise (SME) will have to expand its logistics actions, aiming to generate benefit to the consumer because of actions in the economic, environmental, and social dimensions. Implications for theory and practice:This research expands the literature, as it brings together topics such as sustainability, logistics, supply chain, and agribusiness. The baseline is in the case study with quantitative data that allows us to answer the question of how to be sustainable now, rather than waiting for supply chains to do it first so we can discover it.

PurposeThis paper analyzes managerial practices currently used for outsourced logistics activities in mechanized cutting, loading and transportation (CLT) of sugarcane in a Brazilian company using performance-based logistics contracts (PBL) as reference.Design/methodology/approachThe methodology draws on literature review, design of an analysis model, small group meetings with academics/industry professionals and practical application through a case study. The model is based on PBL and its construction involved choosing the analysis axes, defining evaluation items and respective measurement scale and the means and sources of data collection.FindingsWhen comparing the evaluation results with PBL recommendations, it is possible to see that there are still many improvement opportunities. In contracting axis, decision-making process was poor-rated due to the absence of strategic considerations to support outsourcing decision. Procurement, contract and implementation are in intermediate level. Performance management is the most mature axis. However, quality analysis showed intermediate level. In relationship axis, the most relevant gap is the lack of expectations alignment. Remaining items showed intermediate levels of compliance but still need focusing on communication, establishing a structured relationship management development.Originality/valueThis study contributes first to develop an analysis model based on PBL to evaluate the level of relationship integration between company and logistics service provider, and second, to apply the model to an empirical case in a CLT company operation. As a result, the analysis model presents guidelines for the company, not to just contract/rent equipment and manpower but hire results.
