Design/methodology/approach LSS is a business process improvement strategy widely used in the manufacturing field for enhancing manufacturing organization performance. The integration of Lean and Six Sigma will enable the attainment of defects reduction by eliminating non-value-adding activities from production line. LSS framework has been developed with the integration of define–measure–analysis–improve–control (DMAIC) tools and techniques. Findings The finding of this study is that the LSS framework has been successfully implemented in Automotive Component manufacturing organization, and non-value-adding activities and defects from assembly line have been reduced. The proposed LSS framework applies lean tools within Six Sigma DMAIC approach to facilitate waste elimination and defect reduction. The developed framework with linkage of DMAIC tools and techniques reduces defects and non-value-adding activities with enhanced bottom line results. The implementation of proposed LSS framework shows effective improvement in key metrics. Research limitations/implications The developed framework has been test implemented in an Automotive Component manufacturing organization. In future, more number of studies could be conducted. Further, advanced lean tools and techniques could be included in the framework for increasing the effectiveness of production line. Practical implications The proposed LSS framework with linkage of DMAIC tools and techniques has been successfully implemented in an assembly line of Automotive Component manufacturing organization. This method is presently applied for an Automotive Component manufacturing organization; in future, the approach could be applied in different industrial sectors with addition of new tools and techniques for improving its effectiveness. Originality/value LSS framework has been designed and test implemented in an assembly line of an Automotive Component manufacturing organization. Hence, the inferences are practical and key results of the study.

Journal of Cleaner Production, 2015Co-Authors: Sonu Rajak, Sekar VinodhAbstract:Abstract Societal dimension of sustainability is gaining importance during the recent days to cope with recent advancements and Corporate Social Responsibility. In this context, this article presents an approach for social sustainability performance evaluation. The approach has been test implemented in an Indian Automotive Component manufacturing organization. Appropriate Social Sustainability indicators were identified based on literature. Social Sustainability index has been computed as (5.71, 6.99, 8.31) and by matching linguistic label the organization has been identified as ‘Very Socially Sustainable’. The obtained index has been validated using conventional crisp technique and social sustainability index is found to be 6.98. The approach is efficient in measuring the strengths and weaknesses of an individual community or organization with reference to detailed set of indicators so as to identify the weaker attributes. The study provided systematic approach for measurement and analysis of social sustainability performance. The scientific value of the study is the contribution of a conceptual model for social sustainability performance evaluation, computation of fuzzy Social Sustainability Index and identification of weaker attributes. The results obtained using fuzzy approach has been validated with conventional crisp approach. 22 social sustainability attributes out of 60 are found to be weaker and appropriate actions were derived to improve the weaker attributes.

integration of ecqfd triz and ahp for innovative and sustainable product development
Applied Mathematical Modelling, 2014Co-Authors: Sekar Vinodh, V Kamala, K JayakrishnaAbstract:Abstract Automotive organizations need to adopt sustainability principles to survive in a competitive environment. The rapidly changing marketplace also means that organizations need to include innovation in product development. We propose a model that integrates environmentally conscious quality function deployment (ECQFD), the theory of inventive problem-solving (TRIZ), and an analytical hierarchy process (AHP) for innovative and sustainable product development of Automotive Components. The voice of the customer (VOC) was captured and translated to engineering characteristics using ECQFD. Design options were identified using ECQFD and correlated with TRIZ to identify innovative design alternatives. Selection of the best design alternatives under many criteria is a typical multicriteria decision-making problem. We used AHP to identify the best design in terms of innovation and sustainability. These design changes were then incorporated in the Component. A case study involving design of an Automotive Component demonstrates the applicability of our approach.

Selection of the spraying technologies for over-coating of metal-stampings with thermo-plastics for use in direct-adhesion polymer metal hybrid load-bearing Components
Journal of Materials Processing Technology, 2008Co-Authors: Mica Grujicic, X. Xuan, Velmurugan Sellappan, Norbert Seyr, Marc Erdmann, Laine Mears, Jochen HolzleitnerAbstract:Abstract The suitability of various polymer-powder spraying technologies for coating of metal-stampings used in polymer metal hybrid (PMH) load-bearing Automotive-Component applications is considered. The suitability of the spraying technologies is assessed with respect to a need for metal-stamping surface preparation/treatment, their ability to deposit the polymeric material without significant material degradation, the ability to selectively overcoat the metal-stamping, the resulting magnitude of the polymer-to-metal adhesion strength, durability of the polymer/metal bond with respect to prolonged exposure to high-temperature/high-humidity and mechanical/thermal fatigue service conditions, and compatibility with the Automotive body-in-white (BIW) manufacturing process chain. The analysis revealed that while each of the spraying technologies has some limitations, the cold-gas dynamic-spray process appears to be the leading candidate technology for the indicated applications.

Materials Selection for Lightweight Automotive Composite Hand Operated Parking Brake Lever Design with a Weighted Property Index Method
2014Co-Authors: Muhd Ridzuan Mansor, S M SapuanAbstract:In a typical modern vehicle where the Components may rise up to 15,000 parts, the task to select the appropriate material to best suit a required function or application is not an easy task. It is more complicated when the designers is faced by the challenged of having overwhelming information on various materials available at the market to choose from to match the required Component function. Thus, the need for a systematic and quantitative material selection process is very important to aid the task in choosing the optimum material which gives the maximum benefits to the Component such as in function, cost and reliability. One of the solutions is through a systematic material selection process called the weighted property index method. In this exercise, the weighted property index method is applied in the design of an Automotive Component. The aim is to identify a new material for the construction of a lightweight Automotive hand operated parking brake lever based on the performance requirements set for the Component.

hybrid natural and glass fibers reinforced polymer composites material selection using analytical hierarchy process for Automotive brake lever design
Materials & Design, 2013Co-Authors: Muhd Ridzuan Mansor, S M Sapuan, E S Zainudin, A A Nuraini, A HambaliAbstract:Due to recent trend and increasing awareness towards sustainable product design, natural based fiber materials are gaining a revival popularity to replace synthetic based fiber in the formulation of composites especially for Automotive structural and semi structural applications. In this paper, the Analytical Hierarchy Process (AHP) method was utilized in the selection of the most suitable natural fiber to be hybridized with glass fiber reinforced polymer composites for the design of a passenger vehicle center lever parking brake Component. Thirteen (13) candidate natural based fiber materials for the hybridization process were selected and analyzed to determine their overall scores in three (3) main performance indices according to the Component product design specifications. Using the AHP method, the kenaf bast fiber yields the highest scores and was selected as the best candidate material to formulate the hybrid polymer composites for the Automotive Component construction. Sensitivity analysis was also performed and results show that kenaf bast fiber emerged as the best candidate material in two out of three simulated scenarios, which further validates the results gained through the AHP method.

Environmental impact assessment of an Automotive Component using eco-indicator and CML methodologies
Clean Technologies and Environmental Policy, 2012Co-Authors: S Vinodh, K Jayakrishna, Dino JoyAbstract:The environmental conscious manufacturing and climate change made Automotive manufacturing organisations to recognise sustainability as a vital concept for survival in the global competitive scenario. Many Components of automobiles are manufactured using plastics which play imperative role in ensuring sustainability. This research article deals with the application of Life Cycle Assessment on instrument panel of an electric car which is made of ABS (Acrylonitrile–Butadiene–Styrene). The case study has been conducted in an Indian instrument panel manufacturing plant. First, a life cycle model of ABS sheet which is particularly used in instrument panel manufacturing was built, and the environmental impact assessment of the instrument panel was done using Eco-indicator and CML methodologies. In life cycle perspective, the environmental hot spots have been found out. Later the results have been interpreted based on environmental impact assessment factors. The relative comparison of impact factors at different stages in the life cycle enables the generation of improvement options. The sustainability index of instrument panel before and after implementing Environmental Impact Assessment (EIA) has been computed. The results are statistically validated, and the managerial implications have been derived.

Environmental impact minimisation in an Automotive Component using alternative materials and manufacturing processes
Materials & Design, 2011Co-Authors: Sekar Vinodh, K JayakrishnaAbstract:Abstract Sustainable development is seeking to meet the needs of the present without compromising those of future generations. The need to integrate the principles, values, and practices of sustainable development into all aspects of manufacturing, in order to address the social, economic, cultural and environmental problems is felt widely among the industrialized society. Selecting or identifying a suitable material or manufacturing processes is one way of achieving sustainability of a product by reducing its end of life impacts to a possible extent. But technological changes are unpredictable and so predicting future possible environmental impacts are highly difficult. This paper tries to explore the potential of environmental impact minimisation using alternative materials and alternative manufacturing processes. A case study has been carried out to in this regard in an Indian Automotive Component manufacturing organization. The results indicate that change in material has higher impact over the manufacturing process in reducing the environmental impact.
