Value Stream Mapping in the Textile Industry with focus on Reducing Waste on Circular Knitting

This present study is conducted in an active textile company with a high national market share. For such, it shall demonstrate the current standard of material flow between the circular knitting sector (half stitch production) and the tissue beneficiation sector (dyeing and/or stamping), confronting it with the objective of identifying possible incremental improvements. It is thus proposed the use of principles from the Lean Systems for process optimizations, like Just in Time and Value Stream Mapping, reporting the possible benefits after implementation of the proposed system, and projecting the gains through descriptive statistics. The implementation of this research can be a critical success factor for operational excellence, thus aiming to reduce production costs and increasing competitiveness

How has social media been affecting problem-solving in organizations undergoing Lean Production implementation? A multi-case study

This paper investigates the impact of social media utilization on problem-solving routines in organizations undergoing Lean Production (LP) implementation. A multi-case study was conducted in three firms from different sectors with distinct maturity levels of LP implementation. Empirical evidence was collected through complementary ways, such as semi-structured interviews, secondary data, and in loco non-participant observation. Data were then analyzed and triangulated, leading to propositions on the effects of social media on problem-solving activities in lean organizations. This research was grounded on the concepts of Information Manipulation Theory. Our findings suggest that, while social media may contribute to the amount of information that is shared for solving problems, the relevance and the level of details of such information may be shallow, overburdening the help chain mechanisms and generating wastes like overprocessing. The identification of the impact of social media on problem-solving activities enables a better comprehension of how new information and communication technologies can promote (or impair) the intra- and inter-organizational links. It also helps identify improvement opportunities in integrating social media into problem-solving routines, resulting in more responsive and competitive organizations

Lean accounting: a structured literature review

The purpose of this paper is to perform a review and analyze the literature on Lean Accounting (LA), to develop insights into how LA research is developing, offering a critique of the research to date, and underlining future research opportunities. This research uses a structured literature review to categorize and analyze 39 research articles from relevant journals with a publication date from 1996 to 2020 (September) and to answer three research questions. Findings demonstrated that although LA seems to be the most suitable method for lean companies, it still lacks research in terms of the role of accountants in lean organizations as well as how its concepts are integrated with the Generally Accepted Accounting Principles (GAAP). This paper provides both academics and practitioners with valuable insights regarding the role of management accounting and accountants in the pursuit of lean transformation, presenting meaningful themes and a complete analysis of the literature along with research gaps for future research. This paper contributes to lean manufacturing literature by providing a comprehensive structured literature review of articles regarding LA. Also, it serves as a basis for developing future research agendas in management accounting practices for lean organizations

A sustainable circular 3D printing model for recycling metal scrap in the automotive industry

Industries and businesses are pursuing Industry 4.0 (I4.0) technologies and adopting a circular approach focused on improving manufacturing processes through the reduction of wastes, CO2 emissions, and mineral exploration to mitigate the impact of climate change. In this sense, Additive Manufacturing (AM), often referred to as 3D printing, can play a vital role in the closed loop of operations. However, academics and practitioners have scarcely discussed the feasibility of AM implementation alongside Circular Economy (CE) practices, the techniques and methods required, or how AM could benefit sustainability and circularity. This paper proposes a novel circular sustainable 3D printing model for scrap recycling in the automotive industry to address these gaps.The methodology uses a literature review-based approach followed by empirical research using metal scraps as the raw material for fabricating a powder to input a metal 3D printer for generating sustainable automotive components. A conceptual sustainable circular model for the automotive industry is proposed. Next, is conducted a focus group comprised of AM and automotive industry experts for evaluations. The results indicate that the proposed model can reintroduce waste back into the manufacturing chain as raw material for the on-demand manufacture and supply of automotive components and that it may also have social and environmental implications. This paper’s contributions are threefold: it explores the combined use of I4.0, CE, and Sustainability in the automotive industry, develops a new model to support the circularity and sustainability of the scrap chains, and proposes the use of AM as a catalyst of CE practices by reproducing recycled components with a 3D printer for fully functioning components

Synergy between Principles of Lean Thinking and BIM Functionalities in Interdisciplinarity of Management in Industrial Plants

There is a real need for decreased waste and rework in the construction industry, especially for organizations to become globally competitive. A solution to these challenges is proposed in this research, from an interdisciplinary management model in construction projects through integration between principles of Lean Thinking and BIM functionalities within the PDCA cycle.
