Abstract Paper aims To shed light on how knowledge is shared between companies during a collaborative new product development (NPD) process. Originality It is the first study of different knowledge sharing levels for each stage of the NPD process in an inter-organizational context. Research method A research framework was created based on the literature. Guided by this framework, an in-depth case study was performed in a multinational company analyzing the knowledge sharing with the company’s supplier during a collaborative NPD process. Main findings Different levels of knowledge sharing were found at each stage of the NPD process. Implications for theory and practice The results complement previous works demonstrating that this phenomenon should not be considered as a binary state. By clearly presenting how knowledge sharing occurs at each phase of the NPD process, managers can be prepared and correctly implement tools to support NPD teams from both buyer and supplier companies.

Abstract Paper aims The paper seeks to compare the performance of three layouts in a make to order (MTO) production system with high product variability. Originality No previous work sought to compare job shop, cellular and virtual cell layouts in an MTO system with high product variability, with just 21 resources, a low amount. The analysis considered models with the same capacities and demand for the three layouts. Research method The complete factorial design and ANOVA were used with simulation. The main effects plots of the control factors for response variables were obtained (e.g. throughput, lead time, and resource utilization). Main findings The virtual cell layout had results similar to the job shop, but achieved better outcomes compared with the traditional cell. Implications for theory and practice The knowledge gap regarding virtual cells signals the importance of this topic, as well as the possibilities not yet investigated about it in manufacturing companies.

Abstract Paper aims This study aims to accounting for greenhouse gas emissions from traffic rearrangement, using a network vulnerability framework. Originality We present a new procedure to verify the effectiveness of accident risk as an attribute to find the most vulnerable links of a road network, estimating the amount emitted in the process. Research method Vulnerability is measured by the variation in CO2 equivalent emitted and total distance traveled, after changes in accessibility patterns. Main findings To date, limited research exists on accounting for emissions from the perspective of vulnerability. Three scenarios of risk-level and traffic conditions were modeled. Results indicate that high levels of accidents exposure may increase emissions by 5.2% compared to a low-risk scenario, and 9.1% compared to an unabridged network scenario. Implications for theory and practice The proposed framework could support governmental policies and urban planning to verify the impact of accessibility patterns in GHG emissions.

Abstract Paper aims To shed light on the state of the art of the academic production in Ergonomics. Originality There is no study on the Brazilian academic production in Ergonomics for the last 30 years. Research method Based on the Capes database, the abstracts of 1471 theses/dissertations from 2007 to 2017 were classified by approach and focus. Main findings 58.9% of the studies are diagnoses and only 1.4% presents complete projects for work optimization, what might indicate a difficulty of implementing ergonomic interventions in Brazilian companies. 52% of the publications are from national meeting proceedings and only 5.4% from international journals. Implications for theory and practice The lack of clear objectives, main results and applications in the abstracts reduces the potential interest in the studies. This, and the low number of intellectual production (less than one publication/study) impact the dissemination of knowledge.

Abstract Paper aims Extant Literature based on the resource-based view (RBV) of the firm suggests that it can be used to study organizations of all types and sizes. In essence, the RBV argues that firms that possess rare, non-imitable, valuable, unique, and non-substitutable resources will outperform firms that do not possess such resources. This study questions the applicability of this assumption to smaller businesses, which are likely to have common resources readily available in the market rather than rare, non-imitable, non-substitutable, unique, or valuable resources. The purpose of this study is to discuss whether the composition-based view (CBV) of the firm offers a more promising approach than the RBV to studying small businesses. Originality This study is one of the first to tentatively suggest a change in theoretical approach when studying small businesses. Research method A structured critical review approach is taken. Main findings The findings reveal that the CBV offers a more promising and appropriate theoretical framework than the RBV for research on small businesses, whereas the RBV is better suited to research on larger firms. Implications for theory and practice Future studies can use the RBV and the CBV to study large and small businesses, respectively.

Abstract Paper aims To study fall-accident cases in order to analyze the commonly missing or not adequately applied risk management measures (RMM) and its consequences depending on falling height. Originality First study to analyze failed RMM for preventing falls from height. Research method The study reviewed court cases published by the journal “Safety & Health Practitioner”. NIOSH recommendations were used to define RMM to apply to this study. Main findings Finally, in 98% of analyzed cases, the fall from height was a result of several non-adequate or missing RMM: in 81.6% procedures of work, 65.8% guardrails and edge protection, 60.5% risk assessment, and 60.5% platforms or scaffolds. It can be concluded that falls from height pose a significant risk for workers, which could be prevented by adequately apply RMM. Implications for theory and practice The focus in the prevention of falls should be given on most common RMM.

Abstract Paper aims This paper aims to analyze the literature on standard management systems (ISO 14001, OHSAS 18001, SA 8000, and ISO 26000), and to propose a conceptual framework relating these standards to sustainability (based on TBL) to help answer the following research question: How does the literature address IMS and sustainability based on TBL? Originality This research sheds light on controversies, discussed in the literature, concerning the effects of IMS with sustainability standards. Research method The methodological approach used is a systematic literature review based on bibliometric theory and social network analysis. A conceptual model is presented, linking the main constructs, variables, and their relations to better understand the role of IMS as a driver for sustainability. Main findings Briefly, results show that more research is needed on the social dimension of Triple Bottom Line, especially in the standards OHSAS 18001, ISO 26000, and SA 8000. Moreover, there is a gap considering empirical data on relating IMS impact on performance. Implications for theory and practice This paper contributes by proposing a conceptual model, defining the variables and presenting four relational propositions among the key variables. In a future research agenda, this study could be applied to survey-based research to answer the research propositions suggested.

Abstract Paper aims This paper identifies, evaluates and structures the research that focuses on supply chain coordination, cooperation and collaboration (CCC) within the domain of production economics and reveals its intellectual foundation. Originality The paper develops a distinct CCC-model, which enables a clear distinction between the elements of CCC based on five criteria. Afterwards, it presents the most influential papers and authors when it comes to CCC in supply chain production economics research. It also provides a visualised intellectual structure of five citation subfields and their interrelations. Research method Based on the reference list of more than 270 CCC-related papers, the authors perform a citation and co-citation analysis of the 47 most frequently cited papers in one selected academic journal. This analysis included multidimensional scaling, factor analysis as well as cluster analysis. Main findings The study reveals the intellectual base of CCC in a production economic-specific research domain, which reflects coordination only. The citation clusters represent different aspects of supply chain coordination mechanisms such as contractual agreements, information sharing and buyer-vendor integration. One subfield represents methodological aspects. Implications for theory and practice Neither cooperation nor collaboration related sources were identified in the most frequently used papers which certainly offers a research gap that needs to be closed in the future.

Abstract Paper aims This research aims to evaluate factors that influence knowledge sharing in automotive production context in Brazil and China. Originality Despite the growing recognition of the factors that enable knowledge sharing in organizations, our understanding about the unique challenges encountered by the blue-collar workers in a production context is rather limited. Also, the paper raises issues and challenges involved for production organizations to engage in cross-national knowledge sharing, which remain relatively under-explored. Research method Drawing on the Analytic Hierarchy Process (AHP) approach, we conduct a comparative survey among the production managers in five automotive plants in China and Brazil. The AHP approach is based on Objective: Promote knowledge sharing among production workers; Criteria of knowledge conversion as Socialization, Externalization, Internalization; and Alternatives as Structure, Communication, Training, Incentive, Standard Operating Procedure, Problem Solving Methodology. The methodology focused on the 3 Brazilian and 2 Chinese automotive plants in our fieldwork. Main findings While many authors argue that socialization (dialogue) is the key form of worker knowledge sharing, our findings indicate that workers and managers perceive internalisation as more important in the automotive context. The significant differences between Chinese and Brazilian workers on the relative importance they attributed to knowledge sharing processes and corresponding enabling factors reinforce our understanding about the challenges of knowledge sharing across cultures and lends support to a more particularistic debate of knowledge management. While automotive workers in Brazil preferred to receive more training and better incentive schemes as essential knowledge sharing support mechanisms, Chinese workers valued more standardization through structure and standard operation procedures. The study reaffirms the role of knowledge sharing in continuous improvement and incremental innovation in shop floor operations. Implications for theory and practice In lieu of the gaps in the extant literature, this research aims to further identify and evaluate factors that influence cross-national knowledge sharing in automotive production contexts. The research addressed the gaps to promote supportive ways to provide employees interaction, best practices and lessons learning sharing.

Abstract Paper aims This paper studies a new optimization problem called the Electric Boat Charging Problem (EBCP), which is based on the application of electric mobility in a river transport operation problem. Originality This work pioneers the studies of the electric mobility on the river operations, by proposing the EBCP. This problem includes real features of the electric mobility such as nonlinear charging functions, battery degradation costs, and speed variation. Research method For solving the EBCP, we propose a Mixed-Integer Linear Programming (MILP) formulation. For testing our MILP formulation, we use a set of instances based on a future transport operation. We also analyze the impact of some problem parameters on the objective function, and decision variables. Main findings Our MILP formulation is capable to optimally solve different type of instances in competitive CPU times. The battery capacity and a time limit constraint have and important impact on the objective function and the decision-making variables. Implications for theory and practice We model the EBCP as a MILP formulation. This model allows to optimally solve industrial scale instances. Moreover, using a sensitivity analysis, we unveil that both the battery capacity and the time limit constraint of the EB route are critical parameters.

Abstract Paper aims “Without purchasing, Industry 4.0 will not take place”. Procurement ensures supplies at the lowest level of costs. Those costs account for more than 50% of the gross production value. This paper analyses, explains and proves that digitization reduces cost even further. Originality This empirical examination as well as the explanatory approach are key supplements to previous survey-based studies on the effect of digitization on procurement costs. Research method The digitized procurement process and the application of technologies were analysed in detail by establishing a Procurement 4.0-Framework in order to prove evidence of digitally induced cost-cutting effects. The hypothesis that the use of Industry 4.0-Technologies leads to cost reductions is empirically tested with data by the federal statistical office. The Pearson correlation coefficient measures the strength of correlation between the degree of technology usage and costs of material and commodities. The correlations are empirically tested using a t-test. Main findings The correlations’ strength between digitization and the development of procurement costs enables to confirm the hypothesis and allows an in-depth analysis of technology-specific effects based on a Procurement 4.0-Framework. Implications for theory and practice This paper effectively supports the implementation of technologies for the reduction of costs.

Abstract Paper aims To find efficient operation room scheduling for residents considering several resources constraints and ensuring a minimum number of surgeries for approval in the training program. Originality We find no research in current literature addressing operation room resource allocation for residents training in order to meet legislation approval criteria. Research method The number of procedures to be performed by each resident was defined by Brazilian legislation and by the rules obtained from interviews with the chief professor of a vascular hospital. To solve the allocation of doctors to surgeries planning problem, also addressed in literature as Master Surgical Schedule (MSS), we propose a mathematical programming approach. Main findings The mathematical model showed that some of the current rules of resource availability bring about infeasible planning when trying to achieve the legislation quantitative rules for the residents training. Implications for theory and practice The model allowed the decision maker to plan and schedule vascular surgeries in a better and faster way, through an automated system, instead of allocating residents to surgeries manually, which takes many hours per month. Furthermore, changing the input data in the proposed model can allow other hospitals or specialists to get efficient results in less time.

Abstract Paper aims The study proposes a benchmarking instrument that enables managers to critically assess the volatility management performance of a product’s supply chain to identify areas on which to focus when managing supply chain volatility (SCV). Originality To the best of the authors’ knowledge, the paper is the first to develop an instrument to assess the current state of SCV management of a product’s supply chain. Research method The benchmarking instrument is based on volatility performance data from 87 manufacturing firms. Additionally, a confirmatory case study in the automotive industry is performed to demonstrate the applicability of the instrument. Main findings An industry benchmark is conducted that provides valuable information for practitioners about the current state of volatility management performance in the manufacturing sector. This is of high importance since performance data generated by the focal firm itself are more valuable if they can be put into context with the performance data of competitors. Implications for theory and practice Since SCV can originate from multiple sources, a case-based evaluation of of SCV of a product’s supply chain is necessary. By applying the instrument, managers will be enables to initiate purposeful strategies that focus on the most pressing sources of SCV.
