Abstract

Purpose

The maintenance department of today, like many other departments, is under sustained pressure to slash costs, show outcome and to support the assignments of the organization, as it is a commonsensical prospect from the business perspective. Therefore, the purpose of this paper is to find out the wastes level present in maintenance and, after that, do the ranking of maintenance wastes currently present in the operations of Indian organizations with the help of a questionnaire survey.

Design/methodology/approach

For this, a database of 421 Indian industries was identified and a structured questionnaire was designed. The questionnaire was divided into two sections A and B to assist with data interpretation. The aim of section A was to build general information of participants and their position, type of organization, number of employees, annual turnover of the organization, etc. Section B was also a structured questionnaire developed based on a five-point Likert scale for assessing the level of maintenance wastes currently present in the maintenance.

Findings

Waste of inventory in terms of spare parts storage and obsolesce, etc., waste of rejects/rework/scrap in case of poor maintenance, waste of processing that leads to increases in maintenance and waste of overproduction/excessive maintenance activity has a high level of presence in the maintenance of Indian organizations and gets the top ranks in all the seven types of maintenance wastes.

Practical implications

This paper will be extremely useful for the researchers, maintenance professionals and others concerned with maintenance to understand the after effects of maintenance wastes in Indian industries.

Originality/value

These findings will be highly valuable for professionals relating to manufacturing sector desiring to implement effective maintenance approach in the maintenance management system.

Abstract

Purpose

The purpose of this paper is to propose an interpretive structural modeling (ISM) model which highlights the relationships between the identified just-in-time (JIT) elements useful for the implementation of JIT in maintenance and understand mutual influences of these identified JIT elements on JIT implementation in maintenance. Further, this paper seeks to identify dependence power and driving power of identified JIT elements using an ISM and Matrice d’Impacts Croisés Multiplication Appliquée á un Classement (MICMAC) analysis.

Design/methodology/approach

The methodology used in the paper is ISM with a view to evolving mutual relationships among JIT elements. The identified JIT elements have been further classified, based on their dependence power and driving power using MICMAC analysis.

Findings

This paper has developed the relationships among 16 identified JIT elements using the ISM methodology. Further, this paper analyses the driving power and dependence power of identified JIT elements with the help of MICMAC analysis. The incorporated approach is developed here, as the ISM provides only binary correlation among identified JIT elements. The MICMAC analysis is adopted here as it is useful in specific examination related to driving and the dependence power of identified JIT elements. The ISM developed model and MICMAC analysis finding are validated with the help of industrial experts.

Research limitations/implications

The weightage and validation for the ISM and MICMAC analysis are obtained throughout the opinion of academics and industry experts. Further hypothesis may be conducted to examine the validity of the planned model, and structural model may also be validated statistically with the help of structural equation modeling.

Practical implications

The ISM model development and MICMAC analysis of identified JIT elements provide academics and maintenance managers a macro picture of the profits gained by the organizations by the implementation of JIT in maintenance of an organization.

Originality/value

The results will be useful for maintenance managers to understand the process of implementation of JIT in maintenance and to gain benefits after the implementation of JIT in maintenance of an organization.

Abstract

Purpose

The purpose of this paper is to propose a model (structural equation modeling (SEM)) from the 16 identified just in time (JIT) elements useful for implementation of JIT in maintenance.

Design/methodology/approach

Data were collected using questionnaires posted to 421 manufacturing industries and automotive service industries in India from which 133 usable responses were obtained. First, exploratory factor analysis (EFA) is carried out to identify the factor structure after that confirmatory factor analysis (CFA) is carried out to verify the factor structure of a set of identified JIT elements. CFA is conceded by an SEM statistical technique. In this paper, EFA is applied to extract the factors in JIT implementation by the statistical package for social sciences (SPSS 24) software and confirming these factors by CFA through analysis of moment structures (AMOS 18) software.

Findings

Out of 18 identified JIT elements through literature and expert opinion only 16 JIT elements are selected for the study, two JIT elements removed due to the low value of correlation item-total correlation (CITC). Three factors extracted through EFA, which affects the benefits of JIT implementation in maintenance in quality improvement, production improvement and process control. SEM using AMOS 18.0 was used to perform the first-order three-factor structure (quality improvement, production improvement and process control) of the JIT implementation in maintenance.

Originality/value

The results will be useful for maintenance managers and maintenance professionals to understand the process of implementation of JIT in maintenance and to gain benefits after the implementation of JIT in maintenance in their respective organization.

Abstract

Purpose

The maintenance department of today, like many other departments, is under sustained pressure to slash costs, show outcome and support the assignment of the organization, as it is a commonsensical prospect from the business perspective. The purpose of this paper is to examine expected maintenance waste reduction benefits in the maintenance of organizations after the implementation of just-in-time (JIT) managerial philosophy. For this, a structured questionnaire was designed and sent to the 421 industries in India.

Design/methodology/approach

The designed questionnaire was divided into two sections A and B to assist data interpretation. The aim of the section A was to build general information of participants, type of organization, number of employees, annual turnover of the organization, etc. Section B was also a structured questionnaire developed based on a five-point Likert scale. The identified critical elements of the JIT were included in the questionnaire to identify the maintenance waste reduction benefits in the maintenance of organizations.

Findings

On the basis of the 133 responses, hypothesis testing was done with the help of Z-test, and it was found out that in maintenance, we can reduce a large inventory of spare parts and also shorten the excessive maintenance activities due to the implementation of JIT philosophy. All the four wastes: waste of processing; waste of rejects/rework/scrap in case of poor maintenance; waste of the transport of spares, and waste of motion, have approximately equal weightage in their reduction. Waste of waiting for spares got the last rank, which showed that there are little bit chances in the reduction of waiting for spares after the implementation of JIT philosophy in maintenance.

Practical implications

The implication of the research findings for maintenance of organizations is that if maintenance practitioners implement elements of JIT philosophy in maintenance then there will be a great reduction in the maintenance wastes.

Originality/value

This paper will be abundantly useful for the maintenance professionals, researchers and others concerned with maintenance to understand the significance of JIT philosophy implementation to get the expected reduction benefits in maintenance wastes of organizations which will be helpful in the great saving of maintenance cost and time side by side great increment in the availability of machines.

Abstract

Purpose

In the present context of globalization, maintenance of production systems is very important. A lot of organizations are facing many problems in maintenance management. Therefore, the purpose of this paper is to identify the main problems in maintenance operations and compare these problems with those in manufacturing operations as found in the literature for effective maintenance.

Design/methodology/approach

To identify the main problems in maintenance operations and to compare them with those in manufacturing operations, a large amount of published literature was studied. The paper systematically categorizes the published literature and then analyzes and reviews it theoretically.

Findings

Lack of top management support, lack of measurement of overall equipment effectiveness (OEE), lack of strategic planning and implementation and many more problems are biggest problems in the maintenance operations as well as manufacturing operations. These have emerged as top problems in the implementation of effective maintenance strategies in industries.

Research limitations/implications

From the findings, the authors can conclude that for good maintenance, top management is supposed to be supportive in taking different initiatives. Industrial organizations should focus on improving overall performance of machines identified as OEE rather than only productivity of machines. This paper will be extremely useful for the researchers, maintenance professionals and others concerned with maintenance to understand the significance of maintenance problems in industries.

Originality/value

These findings will be highly useful for professionals from the manufacturing sector in implementing effective maintenance strategy in the maintenance management system.

Abstract

Purpose

Lean and green strategies are good options to increase the environmental and operational performance of manufacturing industries. The purpose of this paper is to identify the critical success factors (CSFs) to implement green lean practices (GLPs) in manufacturing industries through the review of the literature and to develop a conceptual model after analysing the fundamental facilitating factors by using ISM-MICMAC approach.

Design/methodology/approach

The methodology consists of identifying 12 critical success factors (CSFs) for the green lean implementation by reviewing the relevant available literature. The views of eight experts are valued for inter-relationships of these factors. ISM-MICMAC approach is used for analysing the relations between factors and to develop a conceptual model for green lean implementation.

Findings

Twelve CSFs are identified through a review of the literature to adopt GLPs in manufacturing industries. This paper has established the relationships among 12 identified CSFs using the ISM methodology. This paper analyses the dependence power and the driving power of identified CSFs with the help of MICMAC analysis. “Top management commitment” and “Government support” are the most significant CSFs implement GLPs successfully.

Research limitations/implications

The ISM model presented in this study is based on expert opinions. But expert opinions may be biased as these are based on their own judgements. However, the proposed ISM based model needs statistically validations. The ISM model in the present study may be tested in real-world situations of manufacturing industries where results obtained may be different.

Practical implications

This study may provide a useful input for academicians and managers of industries to differentiate between independent and dependent CSFs and their mutual relationships which would help them to focus on those key CSFs that are most significant to implement GLPs.

Originality/value

A conceptual ISM model of identified CSFs shows the different levels of these CSFs. This model may help the manufacturer to implement the green-lean strategies. It may also support policymakers towards adopting GLPs. Arranging CSFs in a hierarchy and to categorise the CSFs into different levels with the help of ISM-MICMAC is an exclusive effort in the area of green lean engagement.

Abstract

Purpose

The circular economy concept in the healthcare supply chain can demote using single-use devices by reprocessing, reusing or recycling. India is the most populous country in the world and has numerous challenges to implementing a circular economy in the healthcare supply chain. The objective of this study is to identify and analyse the roadblocks to circular healthcare supply chains in the Indian context.

Design/methodology/approach

The contribution of the manuscript is to the healthcare supply chain in adopting a circular economy and prioritizing the roadblocks using Fuzzy FUCOM and Fuzzy Bonferroni Mean Operator. A sensitivity analysis is performed to check the robustness of the results obtained.

Findings

The finding of this study suggests that regulatory roadblock is a more important roadblock in adopting the circular economy in the healthcare supply chain. It is expected that the government should formulate precise and consistent guidelines for the implementation of a circular economy in the healthcare supply chain. In addition, for faster implementation, tax rebate policy should be framed for the industries that are taking the initiative to implement a circular economy in their system.

Practical implications

This study explores and prioritizes twenty secondary roadblocks categorized into five primary roadblocks that will enhance the motivation of healthcare industries to become green and circular and contribute to the sustainability in healthcare sector. The government agencies should also take initiatives to create awareness about the circular economy among all the stakeholders.

Originality/value

This research is beneficial for policymakers, researchers, and industrial practitioners and is recommended based on current findings to facilitate the implementation of a circular economy in the healthcare sector.
