Abstract

The commitment to statistical process control programmes is becoming commonplace in US industry. However, some companies are experiencing failure of these programmes, particularly in multi‐strata (population) production processes. Even if such a process is in a state of statistical control, there is a high likelihood that one or more strata could drift away from the target owing to an assignable cause. The success of a QC programme depends on the ability of a quality control practitioner to detect this shift with a greater statistical power (sensitivity) and take corrective actions. Addresses the problem faced by the multi‐strata production process of a local manufacturing company in detecting a single stratum shift from the target with a high level of sensitivity. Proposes the selection of an appropriate sampling method (stratified or random) to have a strong bearing on the relative sensitivity of detecting the above shift in a single stratum. Develops power curves for the above mentioned process under stratified and random sampling scenarios, when a shift occurs in a single stratum. Examines the relationship of sample size to the threshold level of the stratum shift and the preferred sampling method.

Abstract

The relational model and relational database management systems have been the de facto industry standard for organizing and managing data in most computer‐integrated manufacturing environments. In recent years, however, some new database technologies have emerged – namely, object‐oriented and hybrid or extended relational – making the job of the CIM managers more difficult with regard to selecting a database technology that would be most appropriate for their operations. Presents a framework for selecting an appropriate DBMS type in a CIM setting depending on a company′s ENTITY and DATA needs. It is hoped that the presented framework would prove useful to practising managers.

Abstract

Purpose

The unmanned ground vehicle (UGV) described in this manuscript is a robot designed by the authors to map the underground mine environments. The UGV works to develop a computational intelligence-based cyber-physical system (CPS)-based analytical framework for mining operations. The UGV demonstrated excellent semi-autonomous navigation capabilities in the absence of GNSS signals. The UGV has a suite that works in unison to provide relevant information. These sensors are integrated to form a robust sensor fusion-based architecture, creating a CPS with a wide range of capabilities such as data acquisition and navigation in challenging underground environments. UGVs can be used to enhance the efficacy of safety inspections, rescue during underground emergencies and assist miners in hazardous conditions.

Design/methodology/approach

In this research, an UGV was constructed whose operations are enabled by sensors including a D415i Red Blue Green (RGB) depth camera, a LiDAR, a FLIR C5 infrared camera and smart air quality sensors. This sensor fusion-based architecture forms a CPS. Data obtained remotely are processed by deep learning algorithms to achieve overall capabilities such as real-time image analysis for miner identification, object detection, posture analysis and identifying threats of roof falls and overhangs. Simultaneous localization and mapping (SLAM) algorithms create a 3D map, facilitate autonomous navigation and build a decision support system for delivering mine rescue support.

Findings

The aim of this study is to include this capacity in training situations when it has been validated and authorized by the Directorate General of Mines Safety (DGMS) Indian government regulatory agency for safety in mines and oil fields. The longwall demo mine, at IIT (ISM) is being used as the site of the first operations. Once approved by the respective enforcement agencies, this technology and the accompanying rescue and training process can be used in underground operations.

Originality/value

In fact, this paper is the first attempt at remotely operated UGVs based on CPSs, the CPS–UGV in Indian mine conditions, so as to revolutionize Indian mines based on the idea of Industry 4.0.

Abstract

Purpose

The purpose of this study is to identify and address significant quality gaps present in business school dissertations in India. Dissertations, an integral and a special component of the overall business school learning process, acquaint students with the practical business world.

Design/methodology/approach

The authors benchmarked the dissertation processes of business schools in India against those of reputed business schools in Germany, France, Sweden and Australia. Using a survey questionnaire, the authors checked whether business schools in India followed international processes and, if not, what could be done to adopt such processes. A sample of 367 business schools was studied to obtain reasonable evidence.

Findings

There were major quality issues in the dissertation process across business schools in India. Serious groundwork preparation issues were identified, such as an absence of research proposals. Most business schools also reported that there were no rubrics for dissertation evaluation, resulting in high subjectivity in the evaluation process. Supervisor interactions and control over the progress of the dissertation were also found to be very weak. As a result, the authors conclude that dissertations from business schools in India have major gaps in quality.

Originality/value

This is a novel study that examines the quality assurance of business school dissertations. It highlights major quality concerns surrounding the business school dissertation process and suggests measures to address quality issues. The study’s implications apply to business schools in all developing countries and not just India.

Abstract

Purpose

This study aims to assess the impact of academic audit, a quality assurance tool in higher educational institutions. It explores the relationship between the effective use of academic audits and the institutions’ quality performance, as indicated by their accreditation score.

Design/methodology/approach

Using a questionnaire, the authors checked whether colleges across India effectively used academic audits and the key challenges in conducting the audit. A sample of 428 was drawn from a population of 6,201 colleges. The challenges in conducting academic audits, mostly operational, were grounded in literature and measured using a five-point Likert scale. Regression analysis and a t-test were used to test the two hypotheses.

Findings

The effective use of academic audits significantly influences the quality of the colleges measured by the accreditation score. Findings show that ineffective implementation of academic audits leads to mediocre accreditation performance. Simultaneously, the colleges face several challenges in implementing academic audits.

Originality/value

This novel attempt examines the relationship between academic audit and accreditation performance. Through this unique study, the authors make a case for using academic audits by higher educational institutions adopting accreditation as a quality strategy. The research unfolds the significant value that academic audit holds for facilitating accreditation.

Case overview/synopsis

Ankit Tripathi, was a compassionate 22-year-old, the typical lad from New Delhi, India, who seemed driven to change the world. His elder brother Atul Tripathi, a young, creative 25-year-old, was sat there next to him, beaming with pride and gratitude. Both brothers, being mechanical engineering graduates, had experienced the advancement of technology at the cost of Mother Earth. It pained them no end. It was the reason that Atul had refused to serve as an engineer in a government institution after graduating. The parents were shocked when Ankit followed suit. The brothers were poles apart in their personality and temperament, and it was rare to see them agree on anything in this way. Yet, they agreed to disagree with their parents and ventured into becoming entrepreneurs with a purpose and passion to salvage the environment. They had a vision, but without a proper roadmap, it would certainly be a tough game. Nevertheless, they boldly embarked upon their journey and established their start-up “Uneako” in 2019. “Uneako” was a calculated risk, taking into account family resistance (parents’ attitude/perception), personal conflicts (psychological), financial limitations (resources), shallow expertise (professionalism), social concern acceptability and low awareness (environment), government regulations (legalities/approvals), conflicts between brothers (personality issues), etc. Being from a nonbusiness family, the brothers had defied the wave of obstacles and challenges in daring to start their own business, putting at stake the hard-earned money of their father, Satendra Tripathi. Amidst so much social mockery, would Atul and Ankit succumb and become a laughing stock or would they find something that they could live and die for?

Abstract

Purpose

The purpose of this paper is to comprehensively evaluate the progress in the development of trapped vortex combustors (TVCs) in the past three decades. The review aims to identify the needs, predict the scope and discuss the challenges of numerical simulations in TVCs applied to gas turbines.

Design/methodology/approach

TVC is an emerging combustion technology for achieving low emissions in gas turbine combustors. The overall operation of such TVCs can be on very lean mixture ratio and hence it helps in achieving high combustion efficiency and low overall emission levels. This review introduces the TVC concept and the evolution of this technology in the past three decades. Various geometries that were explored in TVC research are listed and their operating principles are explained. The review then categorically arranges the progress in computational studies applied to TVCs.

Findings

Analyzing extensive literature on TVCs the review discusses results of numerical simulations of various TVC geometries. Numerical simulations that were used to optimize TVC geometry and to enhance mixing are discussed. Reactive flow studies to comprehend flame stability and emission characteristics are then listed for different TVC geometries.

Originality/value

To the best of the authors’ knowledge, this review is the first of its kind to discuss extensively the computational progress in TVC development specific to gas turbine engines. Earlier review on TVC covers a wide variety of applications including land-based gas turbines, supersonic Ramjets, incinerators and hence compromise on the depth of analysis given to gas turbine engine applications. This review also comprehensively group the numerical studies based on geometry, flow and operating conditions.

Abstract

Purpose

This study aims to examine the relationship between organizational social capital, university image, perceived employability and career satisfaction of information technology (IT) professionals. It also aims to investigate the moderating effects of diverse age groups of IT professionals on the antecedents and consequences of career satisfaction.

Design/methodology/approach

Variance-based partial least square structural equation modeling (PLS-SEM) technique was used to analyze a dataset of 412 responses from IT professionals. The predictive relevance of career satisfaction was estimated through PLS predict, and the relative importance of determinants was analyzed through importance-performance map analysis (IPMA). PLS Multi-group analysis (PLS-MGA) and measurement invariance of composites (MICOM) were used to estimate the moderating effects of age groups.

Findings

The findings of this study indicate that university image is perceived as the crucial factor for career satisfaction by IT professionals followed by perceived employability and organizational social capital. Gender was found to be a positive predictor of career satisfaction. PLS-MGA results indicate that organizational social capital is a prominent predictor of career satisfaction for middle-aged professionals as compared to young professionals as the latter consider university image to be more important.

Originality/value

This is the first study to examine the relationship between organizational social capital, university image, perceived employability, and career satisfaction of IT professionals in a developing country context.
