Abstract

Purpose

This paper aims to investigate the effect of CaF2 (calcium fluoride) addition as a solid lubricant on the friction and wear behaviour of sintered Fe-Cu-C materials under different loads.

Design/methodology/approach

In this study, the effects of CaF2 added in varying weight percentages on the friction-wear properties of Fe-2Cu-0.8C alloys are investigated. Five Fe-2Cu-0.8C-based compositions comprising CaF2 in 0, 3, 6, 9 and 12 Wt.% were prepared using the single-stage compaction and sintering technique. Friction coefficient, wear loss, hardness and compressive strength of the specimens were measured. The worn-out surfaces were analysed using a scanning electron microscope. Friction and wear tests were carried out on pin-on-disc machine under dry sliding conditions at room temperature.

Findings

The alloy with 3 Wt.% CaF2 was found to be useful in improving wear and friction properties, whereas higher contents of CaF2 resulted in increased wear and friction. Apart from enhanced tribological properties, a slight decrease in the compressive strength was also observed in the 3-Wt.%-CaF2-added sample. Adhesion and abrasion were the prominent wear types observed during this study.

Originality/value

A new self-lubricating composite is developed where CaF2 is used as a solid lubricant in a Fe-Cu-C-based matrix. CaF2, being a high-temperature lubricant, is tried and tested for friction and wear at room temperature, and the results show that the addition of CaF2 in Fe-Cu-C improved its friction and wear properties. Thus, the developed material can be used for antifriction applications.

Abstract

Purpose

The present paper aims to draw an attention towards the inclusion of forecast related costs. Its main purpose is to initiate a new line of research/practice including the forecasting expenditure.

Design/methodology/approach

After a relevant review of supply chain/procurement/production planning related literature, it has been observed that the existing work lacks an explicit inclusion of the cost concerned with forecast. The increased cost of forecasting is expected to enhance the forecasting accuracy. At a higher level, product family is considered for the analysis. However, a basic unit of analysis is always a single item production/procurement situation. Therefore, this situation has been discussed analytically with the use of the fundamental equations and an explicit inclusion of forecasting cost for the first time in the relevant literature. Numerous practical applications have been discussed at strategic and operational level. A framework is also presented for future research in this area.

Findings

A specific contribution of the present paper is an approach towards a unique index for relative forecasting expenditure. The suggested index will be useful for comparison purpose. Also, it can be used as a benchmark that can be improved in future.

Practical implications

The case is explained when cycle time is invariant after discussing the other potential applications. Usefulness of the proposed methodology and the index is discussed for the business organizations operating independently or in the supply chains.

Originality/value

On the basis of the forecast, a production or procurement plan is generated in many of the industrial or business situations. In the context of supply chain/production/inventory management, focus is more on demand forecasting techniques or generation of the forecasts in the existing literature. However, the increased costs concerning forecasts are expected to provide more accurate prediction. Therefore, the originality lies in an inclusion of forecast related costs.

Abstract

Purpose

India is edging China to become the most populous country by 2028. More than 60 per cent of the current population of India is between 15 and 59 years of age, whereas domestically, its relatively youthful profile is seen as the biggest challenge for the government, as India is the largest employable manpower base globally. In the past two decades, the rate of population growth in India has reduced, but the skilled labor force is expected to grow almost 2 per cent annually for the next couple of years. Historically, the Indian economy has been mainly agriculturally based, but, with urbanization, the labor is drifting toward service sectors, and people are increasingly looking to develop their skills in sectors such as hotels, restaurants, airlines, retail and health care. To sustain economic growth, there is an urgent need to develop vocational training programs that address current needs. In spite of all the favorable numbers, the question that must be answered by employers and policymakers remains: Is the available labor being skilled appropriately to be employable? The mushrooming of educational and training institutes in India has imparted professional skills to youth, but industry leaders tend to talk about the unavailability of skilled labor, especially in the culinary skills arena. In a country like India, the labor market tends to alternate between the availability and shortage of skilled labor, and so it seems ironic that on the one hand, there is a shortage of staff and at the same time graduates from various colleges and professional institutes remain unemployed; the reason could be lack of employability skills, especially culinary skills. Given this, the hospitality and tourism industry has emerged as the main driver of the service sector in India; it contributes 6.23 per cent to National GDP and 8.78 per cent of the total employment in India, contributing to significant economic growth. In this context, it is imperative for the government to take appropriate steps in devising strategies to address the problem and also secure successful implementation. This paper aims to analyze the Skill India initiative for the hospitality sector and compare it with the realities on the ground, with particular reference to culinary skills.

Design/methodology/approach

The research reported here was conducted using primary and secondary sources. Industry data were collected through focused groups and roundtable discussions. Online sources, magazines, newspapers and books are referred to as secondary sources, and the data collected are critically analyzed to reach a conclusion.

Findings

There is a significant increase in foreign and domestic tourists, and the subsectors discussed are very closely linked to food, health, traditional cooking, regional and seasonal cuisines. The demand for Indian food and slow cooking is increasing; however, despite various government initiatives, there is no significant improvement in the skill set of the available labor. As food is an important component of all tourism packages, there is a particular need for public–private partnerships to take the Skill India initiative to the next level. That said, academic standards and curriculum must align with international quality frameworks and be in sync with current and future industry demands and benchmarks.

Research limitations/implications

The dependence on the sources available online and their credibility remains the biggest challenge; however, increasing the sample size and more participation from nodal bodies and government officials would have broadened the base of the study.

Originality/value

The research adds value for industry leaders and policymakers at large. Educational institutions, students and hoteliers will find it useful as they attempt to bridge the gap and plan a roadmap according to industry requirements.

Abstract

Purpose

This paper aims to evaluate the various dynamic performance parameters of hydrodynamic journal bearings. For this, the bearing’s inner surface is textured with chevron-shaped textures with different texture depths and number of textures in different regions/locations.

Design/methodology/approach

In the present study, the effect of chevron-shaped texture having different values of texture depths, locations and number of textures has been numerically simulated. The dynamic performance characteristics have been calculated by solving the fluid flow governing Reynolds equation using the finite element method, assuming iso-viscous and Newtonian fluid.

Findings

The obtained results indicate that the bearing stability can be improved with the help of surface texture. Among all the investigated texture locations, the maximum increase in stability threshold speed is observed for fully textured distribution. Moreover, for the chevron-shaped texture considered in the present study, the optimum values of texture depth and number of textures have also been determined for maximum bearing stability.

Practical implications

While designing, designers should focus on those optimum values of texture depth, texture location and number of textures which lead to maximum enhancement in bearing stability.

Originality/value

This study is useful in the appropriate selection of chevron-shaped texture parameters on bearing surface for the maximum bearing stability.

Abstract

Purpose

The purpose of this paper is to provide the various steady state parameters of hydrodynamic journal bearings have been determined to get maximum performance enhancement ratio. For this, the bearings inner surface is textured with triangular shape with different texture depths and a number of textures in pressure increasing region. The textured region acts as a lubricant reservoir, which provides additional film-thickness and reduce friction. Therefore, enhance the overall performance of bearing.

Design/methodology/approach

In the present study, the effect of triangular shaped texture on the static performance characteristics of a hydrodynamic journal bearing has been studied. Different values of texture depths and a number of textures have been numerically simulated in pressure developing region. The static performance characteristics have been calculated by solving the fluid flow governing Reynolds equation using the finite element method, assuming iso-viscous Newtonian fluid. The performance enhancement ratio, which is the ratio of load carrying capacity (LCC) to the coefficient of friction (COF) has been calculated from results to finalized optimum design parameters.

Findings

The paper provides numerically obtained results indicate that surface texturing can improve bearing performance if the textured region is placed in the pressure increasing region. Moreover, surface texturing is the most effective at bearing performance enhancement when the bearing operates at lower eccentricity ratios and texture depth. The performance enhancement ratio, which is the ratio of LCC to the COF is found to be a maximum value of 2.198 at texture depth of 1.5, eccentricity ratio of 0.2 and the textured region located in the increasing pressure region.

Research limitations/implications

The present study is based on a numerical based research approach, which has its limitations. So, researchers are encouraged to investigate the same work experimentally.

Practical implications

The paper includes implications to be beneficial for designers for designing better hydrodynamic journal bearings.

Originality/value

For the triangular shaped texture, considered in the present study, the optimum values of texture depth and texture distribution region have also been determined. While designing, designers should focus on those values of texture depth, texture region and a number of textures, which give the maximum value of performance enhancement ratio, which represents maximum LCC at the lowest value of the COF.

Abstract

Purpose

The purpose of this paper is to investigate the impact of total productive maintenance (TPM) and total quality management (TQM) practices on operational performance and their inter-relationship.

Design/methodology/approach

The present study includes three main constructs, namely, TPM, TQM and operational performance of pharmaceutical industry. Under TPM, four constructs, namely, disciplined maintenance, information tracking, housekeeping and operator involvement has been considered with the help of literature. In TQM, four constructs, namely, quality data and reporting, product innovation, research and development (R&D) management and technology management has been considered. Out of 410 Indian pharmaceutical plants contacted for survey, 254 responses have been used in the study for analysis. The factor analysis, path model and structural equation modeling has been used to analyze the proposed framework. The results for alternate models has been studied, interpreted and reported. Finally the direct and indirect effect of TPM and TQM on operational performance has been tested and checked for proving and disproving the hypotheses.

Findings

TPM practices have a significant impact on plant-level operational performance. When TPM and TQM practices are coming together to achieve operational performance, then TPM is having strong influence on operational performance. TQM is having significant support from TPM to achieve operational performance. TPM impact TQM and TQM in turn helps to achieve operational performance. TPM practices impact significantly R&D, product innovation and technology management, whereas quality data and reporting is the least contributor toward TQM. This may help industry to understand implications of implementation of TPM and TQM to achieve plant-level operational performance. TPM will help to reduce the cost of quality in terms of reduced scrap and less defective products.

Practical implications

The present study provides the useful insights to practicing managers. In literature it has been mentioned that TQM helps in TPM implementation. In practice TPM plays a great role to achieve quality in processes and therefore in products. In turn quality products, with reduced work in process inventory, less defective products and reduced scrap helps to achieve the operational performance at plant level. TPM practices will help the organization to improve the pace of product innovation and improvement in productivity, which is critical to pharmaceutical industry. The continuous monitoring of TPM practices can help organizations to run day to day operations and maintenance requirement of each machine over a specified period of time.

Originality/value

The present study diagnoses the inter-dimensional linkage between TPM, TQM and operational performance. The pharmaceutical industry is complex system of advance equipment’s and processes. After human resources, the health of machines/equipment’s describe the strength of an organization. The machines require the regular maintenance to produce the products with desired specifications. The specifications in medicines and very tight, which can be achieved only if machines/testing equipment’s are updated and maintained regularly. The TPM practices will helps the plants to achieve the operational performance by having quality in processes.

Abstract

Purpose

The paper aims to research the current understanding of Slow Food in the Indian hospitality sector and to identify how the industry can embrace the concept and its sustainability. To begin, underpinnings are considered in relation to traditional, locally produced food for patrons that is actually “farm to fork” in terms of its delivery model as evidenced by backward integration in the supply of key ingredients. The economics of the backward integration is analysed to measure its impact on businesses’ bottom-line in the context of an inflationary economy.

Design/methodology/approach

Existing published literature is reviewed with reference to the “Slow Food movement” from both an international and Indian perspective. Vedatya’s approach to sustainable culinary value chain creation and its applicability for industry adoption with an intent to offer Slow Food on commercial menus is documented and discussed. A round table discussion with key food and beverage leaders is also documented and analysed to establish the current state of awareness and readiness of the sector to offer “Slow Food” through an integrated supply chain in India.

Findings

Slow Food as a concept is new to India; there is a huge shift in many parts of the world towards food that is fresh, traditional and drawn from locally available ingredients. This research shares Vedatya’s experience in developing an integrated value chain that can provide a sustainable Slow Food model for the Indian hospitality and restaurant sector to deploy with a positive impact on profitability too.

Research limitations/implications

There is need for more research to better understand the feasibility of hospitality businesses working on supply chain with backward integration, to offer “Slow Food” to consumers. While there seems to be a demand for traditional food, this paper does not research that aspect; further research is required to ascertain the potential demand for Slow Food in India.

Practical implications

The popularity of Slow Food is global; however, the Indian hospitality sector is yet to warm up to this potential. The customer focus on healthy, traditional, fresh food opens an opportunity to innovate, and businesses that build capacity to offer real farm-to-fork menus can become market leaders and will reap bottom-line benefits through lower input costs because of supply chain integration.

Originality/value

This paper is unique in terms of offering a discussion on the potential of Slow Food as the next realm of culinary innovation in India. It also adds value by sharing the Vedatya experience in terms of developing an integrated supply chain that facilitates the Slow Food offering in a farm-to-fork format. The model can be emulated by commercial hospitality businesses resulting in cost advantages and higher satisfaction levels of customers.

Abstract

Purpose

The purpose of this paper is to investigate the impact of total quality management (TQM) and supply chain management (SCM) practices on operational performance, and their interlinkage between each other.

Design/methodology/approach

Constructs those are critical to pharmaceutical quality and supply chain have been identified with the help of literature and experts from industry. The impact of TQM practices on supply chain practices and on operational performance has been evaluated. Similarly, the impact of supply chain practices on operational performance has been evaluated. Further, alternate models are tested and evaluated through structural equation modeling.

Findings

It was observed during testing of alternate models that TQM practices have a direct impact on operational performance. However, TQM practices also directly impact supply chain components, which, in turn, influence overall operational performance. In comparison of alternate models, the model in which TQM practices affect supply chain practices and supply chain practices further affect the operational performance is found most appropriate.

Practical implications

This study provides some useful implications from industry point of view. TQM practices are critical to pharmaceutical industry. TQM practices are the core of attaining a smooth supply chain, which will have greater impact to achieve operational performance. Strategic supplier partnership, procurement management, information sharing, and quality and inventory management practices are driven by TQM practices. This tri-linkage helps to achieve the desired operational performance.

Originality/value

There are very limited studies that have considered both the areas together to achieve better operational performance. In pharmaceutical industry, both TQM and SCM are the critical areas for any organization to drive its growth.

Abstract

Purpose

The purpose of this paper is to explore the peer-reviewed literature, as well as literature written by practitioners having authority on green supply chains and allied areas with a view to identify future research directions with the help of an extensive literature review.

Design/methodology/approach

In line with this objective, the constructs “Green Supply Chain Practices” and “Green Supply Chain Performance” were the two terms that were identified for a co-relational study.

Findings

As indicated by the literature review, there is a need to do a more detailed study that can pinpoint particular components of green supply chain practices that have a strong association with particular components of green supply chain performance. This paper attempts to achieve the aim by using a different connotation of these two constructs.

Originality/value

Such a study with the connotation and components of green supply chain (GSC) practices and GSC performance as identified and used in this paper might not have been conducted before in the way it is proposed to be used in this paper, thus making this an appropriate contribution. Accordingly, a framework for the research has been depicted, and research questions have been framed.

Abstract

The increasing publicity of recent high‐profile money‐laundering cases has propelled this apparently victimless crime into the forefront of the public domain. However, although this has been one of the government's principal aims — to increase public awareness — there is still a lack of common knowledge within the public domain of what constitutes a money‐laundering offence. The job is further complicated by the fact that this invisible crime operates on the fringes of society, acting as a bridge between the underworld and the rest.
