    Digitalization: a tool for the successful long-term adoption of lean manufacturing
    (Elsevier, 2023) Sangwan, Kuldip Singh
    The lean manufacturing benefits are well documented in literature for different types of industries. However, data acquisition and computation are the basic difficulties or pain points in developing value stream maps to find different types of waste. Industrial internet of things (IIoT) and digital twin enable fast, and dynamic data acquisition and computation with ease. This paper presents digitalization as a tool for the successful adoption of lean manufacturing through real-time data acquisition and computation. The proposed solution incorporates smart low-cost sensor-based data acquisition with a unified dashboard for operational and strategic decision making. The implementation of the proposed unified system is demonstrated through the development of a digital twin and a dynamic dashboard for a modular production system (MPS) assembly line. The dynamic data integration through the deployment of IIoT synchronizes the physical system to dashboard and digital system. The unified dashboard supports effective and timely decision making, especially for shop floors with alternate process plan configurations. The adoption of the proposed solution in an MPS assembly line demonstrates the capability of the architecture as a robust decision support system.

    Integrated Lean Management System for Sustainable Development: A Conceptual Model
    (Excel Publishers, 2011) Sangwan, Kuldip Singh
    Sustainability manufacturing practices like lean and green manufacturing seek to optimize production efficiency while minimizing environmental impact and maintaining social equity. It is also well knowing fact that company that adopt sustainable practices are able to achieve better quality, improved productivity and profitable growth. Among these lean is an important practice that leads us towards sustainability initiatives by eliminating waste at all levels in system and using the resources efficiently. In this paper an integrated lean sustainability development model has been proposed to integrate supplier, organization and customer.

    An ISM approach for lean implementation barriers in labour intensive Indian ceramic SMEs
    (Inder Science, 2022-04) Sangwan, Kuldip Singh
    Worldwide challenges and competition have urged manufacturing industries and organisations to upgrade their proficiency by implementing lean concept. A demographically suitable and reliable structural model of lean barriers has been developed, through which industries can increase their effectiveness of lean practices in labour intensive SMEs. Twelve critical barriers to lean implementation extracted from literature were analysed and validated after discussion with industrial experts/academicians. Interpretive structural modelling (ISM) technique was employed to observe the relationship amongst the barriers and fuzzy MICMAC analysis was performed to identify a model based on hierarchy of these barriers. The results revealed that 'lack of top management commitment and leadership' and 'resistance to change and adopt innovations' as the most critical barriers. The observations of this analysis thus may be considered as a realistic orientation to present scientific and administrative solutions and a road map to improve the lean implementation in context of Indian ceramic SMEs.

    Impact of lean and quality management practices on green supply chain performance: an empirical study on ceramic enterprises
    (Taylor & Francis, 2022-06) Sangwan, Kuldip Singh
    In the last three decades, lean and quality management practices have been employed by the manufacturing organizations but limited studies have analyzed impact of lean and quality practices on green supply chain performance. This study aims to understand the impact of lean and quality management practices on green supply chain (GSC) performance through an empirical investigation. The study also benchmarks the adoption of lean and quality practices and GSC performance for ceramic enterprises. The study adopts multivariate data analysis methods. Four hypotheses have been developed based on the critical analysis of literature. Data was collected from 233 ceramic enterprises, and hypotheses are tested through structural equation modeling and cluster analysis. The results indicate a higher level of implementation of quality practices than lean practices in ceramic enterprises. The statistical results show that the adoption of lean and quality management practices led to the enhancement in operational and environmental performances but a decrease in economic performance. Results also show that the adoption level of these practices is high in large size enterprises, and the GSC performance level is highest for large enterprises, medium for medium enterprises, and lowest for small enterprises. The sector and region-specific focus of the study limits its results from generalization

    Lean manufacturing implementation in an automated production line: a case study
    (Inder Science, 2013-06) Sangwan, Kuldip Singh
    The paper aims at improving production performance of an automated production line by lean manufacturing implementation. The production performance has been improved in an Indian industry by identifying and eliminating non-value added activities through value stream mapping. An increase in the production rate per day by 10.37%, decrease in production lead time by 10.51%, and reduction of non-value added time by 4.00% have been observed. Production levelling has been done to meet the increased customer demand without investment. The present case study will provide the managers an approach to improve productivity even in an automated production line.

    Productivity and quality improvement through value stream mapping: a case study of Indian automotive industry
    (Inder Science, 2012-08) Sangwan, Kuldip Singh
    Value stream mapping (VSM) is one of the most important lean manufacturing tools to identify and reduce all type of wastes in a systematic way. This paper demonstrates the effect of VSM implementation on cost of poor quality, in-process rejections, percentage value addition, lead time, work in process inventory, distance travelled by components and percentage scrap through a case study of VSM implementation in an Indian automotive industry. The results of the study show that the productivity and quality of a company can be improved by implementation of VSM.

    Adoption of Integrated Lean-Green-Agile Strategies for Modern Manufacturing Systems
    (Elsevier, 2017) Sangwan, Kuldip Singh
    Ever increasing customer choices, environmental concerns and competitiveness among manufacturers across the globe has engaged the industry to embrace newer manufacturing strategies. Predominantly, there are three dimensions to modern manufacturing systems viz. economic, environmental and social. The integration of lean-green-agile manufacturing strategies would be a complete and comprehensive manufacturing system which is the need of the 21st century. The adoption of Lean-Green-Agile Manufacturing System (LGAMS) would be facilitated by few enablers. The influence of these enablers is a matter of investigation which is addressed by the present study. An attempt has been made to prioritize the facilitating capacity of each enabler. The outcome of the research would facilitate the policy makers in the industry and government to frame policies.

    Lean manufacturing: literature review and research issues
    (Emerald, 2014-07) Sangwan, Kuldip Singh
    The advent of recession at the beginning of twenty-first century forced many organizations worldwide to reduce cost and to be more responsive to customer demands. Lean Manufacturing (LM) has been widely perceived by industry as an answer to these requirements because LM reduces waste without additional requirements of resources. This led to a spurt in LM research across the globe mostly through empirical and exploratory studies which resulted in a plethora of LM definitions with divergent scopes, objectives, performance indicators, tools/techniques/methodologies, and concepts/elements. The purpose of this paper is to review LM literature and report these divergent definitions, scopes, objectives, and tools/techniques/methodologies.
