Exploring the Application of Lean Best Practices in Remanufacturing: Empirical Insights into the Benefits and Barriers

Remanufacturing processes have been widely identified as being important elements of a sustainable economy. However, the commercial viability of this product recovery route is significantly influenced by several operational challenges that are different from those that occur in conventional manufacturing. One of the most widely used systematic process improvement methods in conventional manufacturing is lean production, which seeks to minimize all forms of waste throughout an operation. As the academic study of lean best practices in remanufacturing processes is relatively new, there is a lack of knowledge regarding implementation and impact. As such, this paper presents multiple case studies investigating the application of lean methods in industrial remanufacturing operations. These studies focus on the automotive industry, where both conventional and remanufacturing operations have been the leading adopters of lean thinking and practice. The results of the investigation identify specific lean methods that help manage the inherent complexity of the remanufacturing processes, and consequently improve the overall productivity of the process. Similarly, factors that limit the application of lean practices within remanufacturing are also identified and discussed. Matrices for opportunities and threats are developed to enable the simple adoption of these findings. Overall, the research provides a more holistic understanding of the application of lean within a remanufacturing environment, with benefits for both academia and industry.

Using Lean tools to improve the efficiency of awake fibreoptic intubation setup

BackgroundAwake fibreoptic intubation is a complex advanced airway technique used by anaesthesiologists in the management of a difficult airway. The time to setup this important procedure can be significant which may dissuade its use by some providers. In our institution, the awake intubation setup process was highly variable and error prone.MethodsWe deployed Lean methods to improve the efficiency and accuracy of the awake fibreoptic intubation setup process. A 2-day improvement event with a multidisciplinary team addressed the setup process, tested solutions and created standard work documents. Twenty awake fibreoptic intubation simulations were conducted before and after the intervention to quantify gains in setup efficiency and error reduction.ResultsVariability in the setup process, including clinical locations visited, was reduced through creating a standardised process. The average time to for an awake fibreoptic intubation setup was reduced by approximately 50%, from 23 min to 11 min (p<0.001). In addition, awake fibreoptic intubation equipment set out without error increased in the postintervention simulations from 59% to 85% (p=0.003).ConclusionUsing Lean tools, we were able to make the setup of awake fibreoptic intubation not only more efficient, but also more accurate. A similar methodological approach may have value for other complex anaesthesia procedures.

The Application of Lean Methods in Corporate Sustainability—A Systematic Literature Review

This paper reviews the application of lean methods for corporate sustainability and highlights demands for future research. With the help of a systematic literature review, papers at the interface of lean and sustainability were identified and matched to a standardized list of lean methods to assess their frequency in the context of sustainability. In a further step, papers containing actual case studies were analyzed in more detail regarding specific application settings, sustainability dimensions, measurability of sustainability impact, and other criteria. The quantitative analysis of 363 publications shows frequent use of lean methods such as just in time and value stream mapping in the context of sustainability, and a surprisingly low use of other approaches such as karakuri, milk run, or chaku chaku. The in-depth analysis of 81 case studies reveals the primacy of intra-company and ecological assessments in the lean context, while social and inter-company aspects remain rather underexposed. This study complements existing research on lean and sustainability by systematically analyzing specific lean methods in the context of sustainability and by further exploring the sustainability characteristics of such lean applications.

IMPLEMENTATION OF THE DESIGN QUALITY ASSURANCE SYSTEM IN JSC “NHC MILES AND KAMOV”

The article reveals the problem of poorly studied methodology of lean design and its practical application. The principle of the Q6 system is described as the basis for the implementation of lean methods in design at NHC Miles and Kamov JSC. The sequence of implementation of the first elements of Q6 within the framework of the project “Design Quality Assurance System” has been determined.

Application of last planner system with BIM in construction plan management

The project team maintains workflow continuity as much as possible to deliver products on time. Nevertheless, poor construction management makes the workflow unstable during the construction process, which leads to the delayed delivery of the building. As different methods to improve production efficiency, Lean Construction and Building Information Modelling (BIM) have a positive impact on the industry. Although many researches have shown the unique advantages of the Last Planner System (LPS) and BIM Technology, the advantages of their integration have not been fully exploited. This paper explores the application of the LPS and BIM in the construction phase through a project that transforms from traditional construction process planning to the use of the LPS. The project results show the impact of the LPS and BIM as lean methods on the project, which can improve the workflow of the construction project by improving efficiency and coordination.

From Lean Manufacturing to Lean Construction: How Principles, Tools, and Techniques Evolved

Lean manufacturing first emerged in the automotive industry. However, low productivity and low efficiency in production are major problems for the majority of industries relying on a heavy workforce. Being one of these, the construction industry suffers from low productivity rates along with inefficient work practices. To prevent those, the industry has shifted its focus from the traditional approach to a more innovative one, which is called Lean construction. Lean construction aims to maximize value while minimizing waste. Therefore, it intends to create safer, smoother, and more efficient processes to eliminate waste. This chapter focuses on Lean construction and highlights the generic Lean tools and techniques practiced in the construction industry indicating its historical journey from Lean manufacturing. The chapter aims to raise awareness towards the efficiency of Lean methods in the construction industry with respect to practices observed in manufacturing.
