Abstract

The effect of the tube wall heat conduction on the natural convection in a tilted long cylindrical envelope with constant, but different temperature of the two ends and an adiabatic outer surface was numerically investigated. The envelope is supposed to be a simplified model for the pulse tube in a pulse tube refrigerator when the pulse tube is positioned at different orientations. It is found that the cylindrical envelope lateral wall heat conduction can enhance the heat transfer from the hot end to the cold end, not only because of the increase in pure heat conduction in the wall, but more importantly, also the intensification of the natural convection within the enclosure. This enhancement is resulted from the big temperature difference between the tube wall and the adjacent fluid near the hot and cold ends. Adoption of low thermal conductivity tube can effectively reduce such additional heat transfers from hot to cold end, thus reducing the loss of cooling capacity for the pulse tube refrigerator.

Abstract

Purpose

Empirical evidences support the benefits of environmental innovation to improve performance. However, previous research has not considered the role of resource alignment in green supply chain management. To fill the research gap, this paper aims to identify resource alignment as a potential moderating mechanism and to examine the relationships between environmental innovation strategy, resource alignment and green innovation performance.

Design/methodology/approach

The empirical study uses a questionnaire approach designed to collect data. Regression analysis is used for hypotheses testing.

Findings

The findings indicate that environmental innovation strategy and resource alignment between partners are positively related to green innovation performance. This study also provides considerable support to the key contingent moderator of resource alignment. The positive effect of environmental innovation strategy on green innovation performance is stronger under the conditions of a higher level of resource alignment between partners.

Research limitations/implications

This study provides empirical support of the ecological modernization theory and integrates partner analysis literature and green management literature. Higher resource alignment may facilitate firms to develop environmental innovation strategy to attain green innovation performance.

Practical implications

Environmental innovation strategy enables firms to integrate ecological issues into their business operation. Managers could learn how to execute environmental incentive programs to promote sustainable development of green new product and green process. Managers need to pay attention to resource alignment that may have moderating influence on the performance outcomes of environmental innovation strategy.

Originality/value

This study highlights the importance of environmental innovation strategy and resource alignment in the process of green management and helps scholars and managers to better understand the moderator of resource alignment in quest of environmental innovation and green management.

Abstract

Purpose

A flexible manufacturing system (FMS) helps improve the system’s performance, thus increasing its overall competitiveness. FMS is an essential component of Industry 4.0 (I4.0), which has revolutionized the way firms manufacture their products. This study aims to investigate the diverse focus of the research being published over the years and the direction of scholarly work in applying FMSs in business and management.

Design/methodology/approach

A total of 1,096 bibliometric data were extracted from the Scopus database from the years 2001 to 2021. A systematic review and bibliometric analysis were performed on the data and related articles for performance measurement and scientific mapping on the FMS themes.

Findings

Based on co-keyword, the study reveals four major themes in the FMS field: mathematical models and quantitative techniques, scheduling and optimization techniques, cellular manufacturing and decision-making in FMSs. Based on bibliometric coupling on 2018–2021 bibliometric data, four themes emerged for future research: scheduling problems in FMS, manufacturing cell formation problem, interplay of FMS with other latest technologies and I4.0 and FMS.

Originality/value

The originality lies in answering the following research questions: What are the most highlighting themes in FMS, and how have they evolved over the past 20 years (2001–2021)? What topics have been at the forefront of research in FMS in the past five years (2016–2021)? What are the promising avenues of research in FMS?
