Abstract

The concept of virtual cellular manufacturing systems (VCMS) is finding acceptance among researchers and practitioners as an extension to group technology. This paper is related to a research work which resulted in designing and developing VCMS, which by virtue of its abilities proves to be attractive to manufacturing organisations fitting into the category of SMEs. VCMS consists of enterprise modeller (EM), cell design manager (CDM), cell operation manager (COM), simulator (SIM), performance evaluator (PE) and report generator (REP). The “cell design manager” is a very important constituent of the VCMS, as this module helps to generate a number of cell configurations using different algorithms. A new algorithm styled as “Better alternative to ROC (BETROC)”, which possesses many distinct features to generate a number of alternative solutions, has been developed and reported in this paper.

The purpose of this research is to discover equipment losses and assess the accomplishment of overall equipment effectiveness (OEE) values.

Abstract

Purpose

The purpose of this research is to discover equipment losses and assess the accomplishment of overall equipment effectiveness (OEE) values.

Design/methodology/approach

Industries specialized in die shops often have issues regarding their efficiencies, conferring to statistics further production line department procedure for various machines frequently suffered restrictions owing to excessive downtime and speed losses in machines thus, reducing their effectiveness and efficiency. OEE is a means of determining how effective a piece of equipment is when in working condition. Calculation of OEE finds the heart of the issue and the root cause for the underlying problem.

Findings

The dimensional outcomes suggest that the average machine effectiveness has not attained the norm of >85%, but there is still room for progression.

Originality/value

One recommended procedure to reduce losses is to keep the actual pace of operation and downtime of equipment constant. Many such suggestions are provided to reduce the losses.

Abstract

Purpose

The purpose of this research paper is to discuss cellular manufacturing is discussed under conditions of changing product demand. Traditional cell formation procedures ignore any changes in demand over time from product redesign and other factors. However given that in today's business environment, product life cycles are short, a framework is proposed that creates a multi‐period cellular layout plan including cell redesign where appropriate.

Design/methodology/approach

The framework is illustrated using a two‐stage procedure based on the generalized machine assignment problem and dynamic programming. This framework is conceptually compared to virtual cell manufacturing, which is useful when there is uncertainty in demand rather than anticipated changes in demand. A case study is used to explain how the concept would work in practice.

Findings

One major characteristic of the proposed method is that it is flexible enough to incorporate existing cell formation procedures. It is shown through an example problem that the proposed two‐stage method is better than undergoing ad hoc layout changes or ignoring the demand changes when shifting or cell rearrangement costs exist. It also sheds some insight into cellular manufacturing under dynamic conditions.

Originality/value

This paper should be useful to both researchers and practitioners who deal with demand changes in cellular manufacturing.

Abstract

Purpose

This study aims to address Industry 4.0 (I4.0) technologies that can improve the research and implementation of lean supply chain management (LSCM) and the enhanced LSCM subfields in I4.0 technologies.

Design/methodology/approach

The authors conducted a systematic literature review to detect, categorize and assess recent data, highlighting patterns and providing suggestions for potential research in this field, to investigate I4.0 literature and its effect on LSCM. The authors examined 79 published types of research from the Scopus database that were published between 2010 and 2021 and classified them into four LSCM fields: logistics, production, supply chain and marketing.

Findings

The authors can emphasize the fact that the literature on this topic is in progress, from early German academic research to the current creation of new effects around the world. The majority of the potential effects investigated were discovered to improve specific areas that ultimately enhance the practices of the four LSCM domains as well as performance outcomes. The authors were also able to assess the extent to which present and upcoming I4.0 technologies can improve LSCM research and implementation.

Originality/value

To the best of the authors’ knowledge, this is the first study of its kind. Although some research looked into various areas of I4.0 and LSCM topics, there has been no research specifically looking into the impact of I4.0 on LSCM. The originality of this study lies in the treatment of the main fields and sub-fields of LSCM, which can benefit from the technologies of I4.0. Academic scholars interested in the research topics may benefit from the findings of this study. Organizations in various industrial sectors, particularly manufacturing, where lean thinking is used, business professionals specialized in lean operations and supply chain management, along with anyone else who wants to learn more about the interrelationships between I4.0 and LSCM.

Abstract

Purpose

The practice of lean management (LM) principles has given firms, from a variety of sectors, quantum jumps in productivity and performance. India is at the cusp of a major leap in economic growth, and adoption of LM is a must for ramping up the rate of growth of the GDP speedily, if the government is really intent on achieving its objective of becoming the third or fourth largest economy soon. This paper aims to study the status of implementation of LM in the LM Leaders (LML’s) in the Indian industry, to understand if they are ready to accept the challenges ahead.

Design/methodology/approach

This is an exploratory research study. To study the level of maturity of LM in Indian industry, the authors selected the LM Leaders in the Indian industry (LMLII). By using a well-known survey instrument – the Lean Self -Assessment Tool (LESAT), Version 2.0 – designed and developed by MIT, the authors conducted a longitudinal survey over the period 2013 to 2016, a four-year duration. Surveys were conducted every year.

Findings

Survey results show an improvement in the overall average of “current state” scores between the years 2013 and 2016, indicating that LMLII’s have improved upon their LM adoption during these years. However, there is a striking gap between “where the industry wants to be” and “where it currently is”. This could drive future improvements. Based on the survey results, this paper draws lessons and proposes action points on how to improve the adoption and diffusion of LM principles and practices in the LMLII. Factors which need to be addressed to reinvigorate the practice of LM have been identified and classified as urgent, immediate and short term.

Research limitations/implications

While many “snapshot” studies have been done to study LM in Indian industry, a longitudinal study has not been done. Moreover, previous studies administer questionnaires to one company (case study method) or a group of companies in a sector of the industry. Thus, there was a research gap. A longitudinal study will help us take a holistic approach. In addition, studying LMLII will provide data from the most serious adopters of LM. Both these will add value to the current research on LM in Indian industry. The results will also help the LMLII’s to further improve the practice of LM in a systematic and rigorous way. However, as the study is limited to the LMLII, it would not be possible to apply the knowledge to the Indian industry as a whole. For doing so, one would need a larger, more representative sample.

Practical implications

Using this paper, LMLII’s can develop practices which will improve customer satisfaction and reduce waste in manufacturing. They can ramp up LM intensity to make further quantum jumps in performance.

Social implications

LM, in addition to improving the output/input ratio (producing more for less), also emphasises waste reduction, customer satisfaction and efficient operations. All these three factors are essential for sustainable and happy society.

Originality/value

The work is original. This is the first longitudinal survey of lean practices in the Indian industry to study cross-sectional practices, and the results will propel the Indian industry to intensify the practice of LM.

Abstract

Purpose

The purpose of this paper is to assess the impact of a maintenance philosophy, Total Productive Maintenance (TPM), on the operational performance of the Portuguese industry, identifying how it enables the systematic reduction of waste in maintenance.

Design/methodology/approach

A structured questionnaire was constructed and sent to 472 Portuguese enterprises, having obtained a sample constituted of 84 valid answers. With a five-point Likert scale, it was possible to assess the impact of the TPM on five operational performance dimensions, being them: quality, flexibility, productivity, safety and costs.

Findings

It was found that the planned maintenance, together with education and training are the practices with the highest degree of implementation in the Portuguese industry, exceeding 70% for both. The productivity is the dimension with a higher degree of impact from the implementation of TPM and costs the dimension that suffered a lesser impact.

Practical implications

This paper shows and analyses the current state of TPM implementation in the Portuguese industry and it will be useful for maintenance professionals, researchers and others concerned with maintenance, in order to understand the effects of TPM implementation on the operational performance of the Portuguese industries.

Originality/value

The findings from this paper will be valuable for professionals who desire and are looking forward to implement an effective maintenance approach in the maintenance management system, in order to achieve the excellence in maintenance.
