Abstract

Purpose

Supplier evaluation is a part of logistic management. In the present era, resilient supply chain performance (RSCP) assessment of the vendor enterprise is respected as a hot topic. The purpose of this paper is to enable the managers to map the performance in percentage system and also enabling managers for identifying the weak indices-metrics, which need to be improved up to ideal or standard level and strong indices-metrics.

Design/methodology/approach

The authors found two research gaps via a literature survey. The first research gap revealed that the performance of a resilient supplier is computed solely in terms of a fuzzy mathematical scale. The articles are not yet published, which could measure the RSCP in percentage. The second research gap argued about the mitigation of the multi-level hierarchical resilient vendor/supplier evaluation framework for materializing RSCP and identifying weak and strong performing indices-metrics. To compensate the both research gaps, the authors developed a novel fuzzy gain-loss evolutionary computational approach to assess the performance of a firm in percentage. Next, a revised ranking technique coupled with trapezoidal fuzzy set based fuzzy performance importance index is implemented on the framework to seek weak and strong indices-metrics. The performance loss of each metric using the ideal solution concept considering the attitude of decision makers is also revealed.

Findings

The authors found the RSC performance of supplier firm 74 per cent, whereas performance loss 26 per cent, while actual performance is compared with standard fuzzy performance index (SFPI). Performance loss 26 per cent can be compensated by improving the performance of weak indices-metrics.

Originality/value

The novelty of the paper is that the authors used the ideal solution concept to compute the SFPI and compare it with actual FPI for evaluating the gain and loss of resilient supplier firm in percentage and identify weak and strong indices so that managers can improve the performance of weak indices. The work possesses the significant for all organizations, as research work enables the managers to map and improve the RSC performance of any vendor firm in future. The presented work considers the case of an automobile parts supplier industry to validate the developed approach.

Abstract

Purpose

Under the influence of loading, manufacturing, installation and other factors, the axis of sleeve bearing and journal will not be aligned, which will have a great impact on running stability and life of bearing. The existence of oil groove can effectively improve the life of sleeve bearing and working efficiency. The lubrication performance of two and three grooves sleeve bearing considering journal misalignment is analyzed.

Design/methodology/approach

To solve the difference of discontinuous position of oil film thickness, it is necessary to use the flow balance relationship in the finite control space, and oil film thickness equation of multi-groove sleeve bearing considering journal misalignment is gained.

Findings

The friction and bearing capacity of journal bearing with oil groove increase with the increase of journal inclination angle. At the same journal inclination angle, the bearing capacity of two-axial groove journal bearing is larger than that of three-axial groove journal bearing, but the friction of two-axial groove journal bearing shows the trend of the first bigger and then smaller than that of three-axial groove journal bearing.

Originality/value

The research has great significance to optimize bearing lubrication performance and increase bearing working life.

Abstract

Purpose

The purpose of this paper is to examine the curvilinear relationship between knowledge leadership and knowledge hiding and the moderating role of psychological ownership on influencing the curvilinear relationship.

Design/methodology/approach

In total, 403 data were collected from participants in a high-technology company via a two-wave survey. Hierarchical regression analyses were used to test the hypotheses.

Findings

Results revealed an inverted U-shaped relationship between knowledge leadership and knowledge hiding. The employees exhibited more knowledge hiding in a moderate level of knowledge leadership than in lower and higher levels of knowledge leadership. Moreover, psychological ownership significantly moderated the curvilinear relationship such that the inverted U-shaped relationship was more pronounced among employees with high psychological ownership.

Practical implications

Employees’ reaction to knowledge leadership may vary from different levels of knowledge leadership. Moreover, organizations should boost employees’ psychological ownership especially for the collective identity that helps them own knowledge as “ours.”

Originality/value

This study extends both the leadership and knowledge management behavior literatures.

Abstract

Purpose

The paper aims to present a dynamic model of flexible oscillating pectoral fin for further study on its propulsion mechanism.

Design/methodology/approach

The chordwise and spanwise motions of cow-nosed ray’s pectoral fin are first analyzed based on the mechanism of active/passive flexible deformation. The kinematic model of oscillating pectoral fin is established by introducing the flexible deformation. Then, the dynamic model of the oscillating pectoral fin is developed based on the quasi-steady blade element theory. A series of hydrodynamic experiments on the oscillating pectoral fin are carried out to investigate the influences of motion parameters on the propulsion performance of the oscillating pectoral fin.

Findings

The experimental results are consistent with that obtained through analytical calculation within a certain range, which indicates that the developed dynamic model in this paper is applicable to describe the dynamic characteristics of the oscillating pectoral fin approximately. The experimental results show that the average thrust of an oscillating pectoral fin increases with the increasing oscillating amplitude and frequency. However, the relationship between the average thrust and the oscillating frequency is nonlinear. Moreover, the experimental results show that there is an optimal phase difference at which the oscillating pectoral fin achieves the maximum average thrust.

Originality/value

The developed dynamic model provides the theoretical basis for further research on propulsion mechanism of oscillating pectoral fins. It can also be used in the design of the bionic pectoral fins.

Abstract

Purpose

In this study, the authors employ an intellectual-capital based view of the firm to examine the relationship between three bundles of human resource development (HRD) practices (i.e. developmental, constructive and collaborative HRD practices), three dimensions of intellectual capital (i.e. human capital, organizational capital and social capital), and organizational performance improvements. Specifically, the authors investigate the mediating role of intellectual capital in the relationship between HRD practices and changes in organizational performance.

Design/methodology/approach

The authors randomly distributed questionnaires to 1,000 HR executives of Taiwanese firms to assess the firms' HRD practices and intellectual capital. Firm performance data in terms of return on assets (ROA) were obtained from the Taiwan Economic Journal (TEJ). To test the model, the authors used the longitudinal data over three years from 213 firms in Taiwan.

Findings

The results show that human capital and social capital mediate the relationship between HRD practices (i.e. developmental and collaborative HRD practices) and organizational performance improvements in terms of return-on-assets growth.

Originality/value

This study adds to the empirical evidence regarding whether or not investment in HRD practices can lead to positive changes in financial performance.
