Abstract

Purpose

The paper presents reliability, maintainability and life cycle cost (LCC) analysis of a computerized numerical control (CNC) turning center which is manufactured and used in India. The purpose of this paper is to identify the critical components/subsystems from reliability and LCC perspective. The paper further aims at improving reliability and LCC by implementing reliability-improvement methods.

Design/methodology/approach

This paper uses a methodology for the reliability analysis based on the assessment of trends in maintenance data. The data required for reliability and LCC analysis are collected from the manufacturers and users of CNC turning center over a period of eight years. ReliaSoft’s Weibull++9 software has been used for verifying goodness of fit and estimating parameters of the distribution. The LCC of the system is estimated for five cost elements: acquisition cost, operation cost, failure cost, support cost and net salvage value.

Findings

The analysis shows that the spindle bearing, spindle belt, spindle drawbar, insert, tool holder, drive battery, hydraulic hose, lubricant hose, coolant hose and solenoid valve are the components with low reliability. With certain design changes and implementation of reliability-based maintenance policies, system reliability is improved, especially during warranty period. The reliability of the CNC turning center is improved by nearly 45 percent at the end of warranty period and system mean time between failure is increased from 15,000 to 17,000 hours. The LCC analysis reveals that the maintenance cost, operating cost and support costs dominate the LCC and contribute to the tune of 87 percent of the total LCC.

Research limitations/implications

The proposed methodology provides an excellent tool that can be utilized in industries, where safety, reliability, maintainability and availability of the system play a vital role. The approach may be improved by collecting data from more number of users of the CNC turning centers.

Practical implications

The approach presented in this paper is generic and can be applied to analyze the repairable systems. A real case study is presented to show the applicability of the approach.

Originality/value

The proposed methodology provides a practical approach for the analysis of time-to-failure and time-to-repair data based on the assessment of trends in the maintenance data. The methodology helps in selecting a proper approach of the analysis such as Bayesian method, parametric methods and nonparametric methods.

Abstract

Global virtual teams (GVTs) – composed of members in two or more countries who work together primarily using information and communication technologies – are increasingly prevalent in organizations today. There has been a burgeoning of research on this relatively new organizational unit, spanning various academic disciplines. In this chapter, we review and discuss the major developments in this area of research. Based on our review, we identify areas in need of future research, suggest research directions that have the potential to enhance theory development, and provide practical guidelines on managing and working in GVTs.

Abstract

Purpose

The study aims, based on the symbiotic relationship between tourism agencies and various stakeholders, to investigate what “policy-level” partners would advise their “practice-level” counterparts on, first, how the World Heritage Site (WHS) status of monuments can be made attractive for travellers, and second, what steps can be taken by stakeholders to enhance the WHS tourist experience.

Design/methodology/approach

A qualitative approach involving e-mail interviews was adopted. Content analyses of open-ended exploratory questions put to “policy-level” respondents yielded 10 major themes that can enhance the brand appeal of the WHS.

Findings

The findings offer in-depth solutions for better trip experiences of Heritage Tourists. Insights from the responses under ten thematic areas have direct relevance for application by tourism and hospitality facilitators.

Practical implications

Although this study was conducted in India, its findings hold implications for practice throughout the world. They could similarly be incorporated as elements of policy directed at incentivising communication of the value of preserving heritage for future generations.

Originality/value

While previous research focused on stakeholders for planning and policy making, this study explores the stakeholder's perspective for a more comprehensive understanding of how using the WHS brand can generate more holistic tourism development.

Abstract

Purpose

The present study analyses Khasi Food as an ethnic food to be promoted as a tourism product encouraging tourists to visit Meghalaya, India. The food tourists are primarily motivated to eat Khasi Food to provide authentic ethnic food experiences. Therefore, the purpose of the paper is to explore the willingness of tourists to eat ethnic foods and the consequent ethnic Khasi Food Experience (KFE).

Design/methodology/approach

This paper adopts a convergent triangulation approach. Statistical data analysis and thematic analysis were incorporated, and the combined results were compared to see if they converged to achieve the same objective or purpose, which is willingness to eat ethnic foods that influences KFE in the study area (selected villages in East Khasi Hills District and West Jaiñtia Hills District).

Findings

The converged findings from statistical analysis and thematic analysis indicate that tourists who visited the study area were willing to eat ethnic foods, which is Khasi Food and their willingness to do so has a positive influence on KFE.

Originality/value

To the best of the authors’ knowledge, this paper is original and the first of its kind because this study has not been conducted yet in the state of Meghalaya, India. This paper has an authentic value of projecting Khasi Food globally as a cultural and ethnic tourism product giving meaningful experiences to tourists and locals alike.
