    Low-Cost Automation Mechanism for Rotor Press Machine
    (Springer, 2022-10) Mathew, Nitin Tom
    Pressing rotors on a high-pressure press are an important stage in the manufacturing of rotors for ceiling fans and other appliances. This pressing is done mainly to eliminate bending or distortion defects formed on its surface due to the aluminum die casting process taken place before. Due to this distortion or bending defects, rotors get rejected during their assembly. The available facility at the organization for this purpose was not very efficient and was causing a lot of production as well as financial loss to the organization. For this purpose, it was proposed to conceptualize, design, and develop a low-cost automation mechanism, which would eliminate this problem. The main task in hand was to make sure the entire diameter of the rotors gets pressed properly in one single stroke of the press machine. For this purpose, design changes in the layout of the machine were done. By using this project, the organization was able to improve its production efficiency, and human intervention in manufacturing activities was reduced to a minimum.

    Development of a lean manufacturing simulation laboratory for continuing education students
    (Sage, 2020-10) Jasti, Naga Vamsi Krishna; Kota, Srinivas; Venkataraman, P. B.
    The objective of the article is to establish the significance of a simulation laboratory especially simulation exercises for continuing education students in lean manufacturing course. Subsequently, identify the influence and analysis of these simulation exercises in exploring, understanding and implementing lean strategies in various contexts. The research is carried out through the following steps: enhancing the course handout and course outcomes, identifying the various lean concepts and proposing relevant exercises, mapping the course outcomes with the proposed exercises, identifying the appropriate simulation tool and developing the proposed exercises, deciding the mode of simulation laboratory offering, offering the selected critical exercises in simulation laboratory, conducting a critical review of simulation exercises with a team of experts and performing a comparative study on the student performance. The study has identified that there was a significant improvement in the performance of the students after participating in the simulation laboratory, especially in achieving the course outcomes. This was established by the analysis of the various examination scores, feedback on simulation exercises and instructors. This attempt is the first of its kind to analyse the student performance after incorporating simulation laboratory in a lean manufacturing course. The focus is on evaluating student performance based on the scores in the examinations. A population of 488 students enrolled in a masters’ degree programme is considered in the analysis 234 (without simulation lab) and 254 (with simulation lab).

    Development of a Model for Total Productive Maintenance Barriers to Enhance the Life Cycle of Productive Equipment
    (Elsevier, 2021) Mishra, Rajesh P
    The main intention of the organization is to focused on enhancing its efficiency, life cycle, and productivity by maintaining better delivery time so that customer satisfying can be guaranteed. One way to achieve this intention is by implementing the concept of Total Productive Maintenance (TPM). In this study, barriers faced by Indian manufacturing organizations in the new emerging market had been determined through the questionnaire survey with the help of renowned academician and industrial experts. These barriers had been divided into key areas namely behavioral, organizational, cultural, technological, departmental, operational, and financial barriers. The barriers had positive as well as negative effects on the actual implementation of TPM aligned with life cycle engineering of productive equipment. The study identifies the crucial barriers to TPM employment in Indian manufacturing industries from the literature review and industrial experience. Hence, a unique model was developed for the determination of the driving and dependence power of the barriers to TPM execution to enhance the life cycle of productive equipment using Interpretive Structure Modelling (ISM).

    The Influence of Manufacturing Plant Site Selection on Environmental Impact of Machining Processes
    (Elsevier, 2019) Sangwan, Kuldip Singh
    Sustainability has become an important aspect in the strategic planning of manufacturing organizations due to rising energy cost, climate change, environmental emissions, and carbon tax policies. Most of the large manufacturing organizations have a worldwide network of factories, which is mainly driven by financial and political aspects. In past few decades, many attempts have been made to improve the sustainability of the manufacturing processes with consideration of carbon efficiency, energy efficiency, and cost effectiveness. The influence of the manufacturing plant site on the environmental sustainability of the manufacturing process is not considered in most site selection decisions despite its importance in improving the sustainability of production networks. This paper investigates the site based factors to influence the environmental sustainability of a machining process and the effect of these factors is analyzed using life cycle assessment. A case study is conducted with eight different cases based on the location of raw material, manufacturing site, and customers in India and Germany. Four key influencing factors are identified and the environmental impact of the milling process is assessed. One of the key findings is the significant influence of climate and the supply chain on the environmental sustainability of the machining process. This study can be used to include the environmental performance of the machining process into the strategic planning of new manufacturing plants.

    Redesigning the efficiency process analysis for working capital models: Evidences from the determinants
    (Emerald, 2020-02) Sharma, Satyendra Kumar; Chadha, Saurabh
    The purpose of this study is to get insights into working capital management (WCM) practices and the determinants of its efficiency prevailing in the Indian manufacturing sector using firm-specific as well as macro-economic variables by examining three efficiency models, i.e. cash conversion cycle (CCC), cash conversion efficiency (CCE) and net working capital level (NWCL).

    Benchmarking business excellence practices: a case-based approach
    (Inder Science, 2021-05) Tikoria, Jyoti
    This paper aims to explore the business excellence practices and the relative importance of success factors by taking a case of an Indian manufacturing organisation for benchmarking purpose. A series of structured, semi-structured, in-depth interviews and company annual reports followed by a questionnaire survey were used to examine current business excellence practices and relative importance of success factors so as to benchmark best in-class practices. Factors namely 'teamwork' and 'culture and core values' are found to be very prominent at the case study of organisation ABC and helped them significantly in enhancing their performance. The rest of the factors are in line with the success factors of prominent global business excellence models. The findings of this study in terms of providing a simple template to assess organisations will be of utmost help to make improvements for moving towards business excellence. The present study reveals that there should be a customisation of the success factors for business excellence based on sector and context specificity.
