Abstract

Purpose

The purpose of this paper is to study the path-planning problem of an unmanned ground vehicle (UGV) in a predefined, structured environment.

Design/methodology/approach

In this investigation, the environment chosen was the roadmap of the National Institute of Technology, Rourkela, obtained from Google maps as reference. An UGV is developed and programmed so as to move autonomously from an indicated source location to the defined destination in the given map following the most optimal path.

Findings

An algorithm based on linear search is implemented to the autonomous robot to generate shortest paths in the environment. The developed algorithm is verified with the simulations as well as in experimental environments.

Originality/value

Unlike the past methodologies, the current investigation deals with the global path-planning strategy as the line following mechanism. Moreover, the proposed technique has been implemented in a real-time environment.

Abstract

Purpose

The present study aims to investigate the experience, contribution and opinions of users of respective institutional repositories (IRs) developed in India.

Design/methodology/approach

The survey method was used. The data collection tool was a web questionnaire, which was created with the help of software provided by surveymonkey.com

Findings

It was observed that 85.94 percent of respondents (154) were aware of the IR facility/service and 14.05 percent (26) were not aware of IR. More than half of the respondents, i.e. 52.43 percent (97), learned about the IR service through links provided on institutions' websites. About 36.21 percent of the respondents had not contributed to any type of repository, while 25.94 percent of respondents had contributed to their IR. A higher percentage (16.76 percent) of respondents felt it was an “easy and fast way to communicate research results”. The majority of the respondents, i.e. 113 (61.08 percent), were willing to deposit symposium/conference/seminar papers. The most important reason for contribution was found to be preservation of documents for the future. Peer review was very much acceptable as a quality control mechanism. More than half of the respondents (57.84 percent) wanted to provide open access without any barrier for their ideal repository.

Research limitations/implications

Only users of the respective Indian institutional repositories are studied, and the findings are compared with other studies.

Originality/value

This is the first detailed study focusing on the users and their experience of institutional repositories.

Abstract

Purpose

With the rising needs of health-care (HC) services during the health outbreaks, it is essential to upgrade the existing HC delivery infrastructure. The study aims to prioritize and highlight the interrelationships among the key factors of the smart health-care supply chain (HCSC) by implementing the concept of Industry 4.0.

Design/methodology/approach

The key factors of implementing Industry 4.0 in HCSC have been identified through extensive literature review and stakeholders' opinions. To achieve the abovementioned objectives, the present study proposed hybrid multi-criteria decision-making (MCDM) tools, namely, the fuzzy-analytic hierarchy process (AHP) and fuzzy- decision-making trial and evaluation laboratory (DEMATEL). The Fuzzy-AHP prioritized the factors of implementing Industry 4.0 in HCSC, while the cause–effect relationships among the factors have been explored using fuzzy-DEMATEL.

Findings

The results of the study indicated that HC logistics management (HCLM) is the most prioritized factor of implementing Industry 4.0 in HCSC, followed by the integrated HCSC, then sustainable HCSC practices, HCSC innovation and technological aspects, HCSC institutional perspectives, HCSC competitiveness, social aspects and economic factors of HCSC. The cause–effect analysis has highlighted integrated HCSC, HCLM, HCSC competitiveness and social aspects as the cause group factors and they are the critical success parameters for implementing Industry 4.0 in the HCSC.

Practical implications

The results of the study can be useful for policymakers, humanitarian organizations, health administrators and other decision makers considering the smartening of HCSC to enhance the operational performance of health facilities.

Originality/value

This is one of the few studies to have been conducted so far in which the subfactors of HCSC implementing Industry 4.0 have been identified and analyzed using the fuzzy-AHP and fuzzy-DEMATEL hybrid approach.
