Abstract

Purpose

The purpose of this paper is to provide an effective solution method for the truck and trailer routing problem (TTRP) which is one of the important NP-hard combinatorial optimization problems owing to its multiple real-world applications. It is a generalization of the famous vehicle routing problem (VRP), involving a group of geographically scattered customers served by the vehicle fleet including trucks and trailers.

Design/methodology/approach

The meta-heuristic solution approach based on bat algorithm (BA) in which a local search procedure performed by five different neighborhood structures is developed. Moreover, a self-adaptive (SA) tuning strategy to preserve the swarm diversity is implemented. The effectiveness of the proposed SA-BA is investigated by an experiment conducted on 21 benchmark problems that are well known in the literature.

Findings

Computational results indicate that the proposed SA-BA algorithm is computationally efficient through comparison with other existing algorithms found from the literature according to solution quality. As for the actual computational time, the SA-BA algorithm outperforms others. However, the scaled computational time of the SA-BA algorithm underperforms the other algorithms.

Originality/value

In this work the authors show that the proposed SA-BA is effective as a method for the TTRP problem. To the authors’ knowledge, the BA has not been applied previously, as in this work, to solve the TTRP problem.

Abstract

Purpose

Steered by upper echelon theory, this study aims to scrutinize the prevalence of project manager demographic factors (age, education and experience) in project sustainability management and project performance.

Design/methodology/approach

We used a sample of 209 project managers/supervisor/team leaders who were working in the projects of the China-Pakistan Economic Corridor (CPEC).

Findings

The results indicate that project manager demographic factors have a significant influence on project performance (except experience) and project sustainability management. Moreover, project sustainability management partially mediates the relationship between age, education and project performance while it fully mediates the path between experience and project performance.

Practical implications

The research recommends senior, high educated and experienced managers for CPEC who promote sustainability and gain high project performance.

Originality/value

A number of studies have been carried out to assess the relationship between top managers’ attributes and environmental activities. However, so far, none of the studies has paid attention to the CPEC and projects working in Pakistan.

Abstract

Purpose

This study aims to minimize the research gap by finding out what are the current state of knowledge management (KM) in the Chinese private science and technology organizations, the essential factors for promoting KM behaviors and the role of knowledge-oriented leadership in determining employees’ KM behaviors. Specifically, this research attempts to create a theoretical framework, which can be used to facilitate KM implementation in general, in the Chinese context in particular.

Design/methodology/approach

Semi-structured interviews with executives, senior managers and specialists were used to capture interviewees’ responses to the research question. The responses were analyzed with Nvivo to detect the obstacles of KM behaviors within Chinese private science and technology organizations.

Findings

This study highlights that poor KM behaviors are caused by knowledge-oriented leaders’ weak awareness of the KM values, and also these leaders are not equipped with the necessary knowledge-oriented leadership skills. As a result, there is a lack of knowledge sharing and knowledge inheritance. To respond to the identified KM related issues, while maximizing the KM values, some effective countermeasures focusing on the strategic, managerial as well as operational levels are proposed.

Practical implications

There is a need for knowledge-oriented leaders to recognize the growing significance of KM practices, and to increase the level of awareness of KM values. To achieve such ambition, they need to build a corporate knowledge culture, which promotes knowledge development, application, preservation, sharing and inheritance.

Originality/value

This study contributes to deepening the understandings of the linkage between knowledge-oriented leadership and KM behaviors, which is of great significance to promote the soft power of KM on employees’ attitudes and behaviors.

Abstract

Purpose

This study aims to empirically examine knowledge management practices in China with the purpose to provide a holistic view regarding the current status of knowledge management at both national and organizational levels.

Design/methodology/approach

Using a survey method, this study collected primary data from organizations across several regions in China. The data were analyzed to detect possible relationships among institutional force, organizational culture and knowledge management process in Chinese organizations. More specifically, to what extent are these relationships moderated by national culture?

Findings

While knowledge management practices in China were partly influenced by institutional forces, most of the predicted connections between organizational culture and knowledge management were supported. In addition, the dynamic nature of national culture is predominant, that pervasively influencing knowledge management processes and thus contextualization determines how knowledge is being managed in China. Indeed, the ideologies of relationships and trust are key vehicles for knowledge management in the Chinese organizations.

Practical implications

This study comprehensively reviews existing literature to form an integrative framework, which is under explored in a Chinese context. Such initiative helps scholars and practitioners to gain a full understanding of knowledge management, in general, in the Chinese business environment in particular.

Originality/value

This paper provides a detailed and empirical insight into the knowledge management practices in Chinese organizations and suggests that knowledge management in a distinctive and yet diverse cultural context should be considered with caution.

This paper aims to explore the psychological process by which front-line employees (FLEs) in hospitality firms make decisions on hiding knowledge.

Abstract

Purpose

This paper aims to explore the psychological process by which front-line employees (FLEs) in hospitality firms make decisions on hiding knowledge.

Design/methodology/approach

A qualitative methodology was used, with triangulated data collection from six different types of hospitality firms. By using the thematic analysis approach, a conceptual framework consisting of seven main themes was constructed to reflect the replicable logic of an individual’s knowledge exchange decision-making in various situations.

Findings

This study proposes a theoretical framework describing how hotel employees evaluate the cost and benefit of knowledge exchange implicitly. Using this framework, this paper illustrates the strategies that FLEs use to make a bounded-rational decision on knowledge exchange in situations characterized by time constraints and limited information.

Practical implications

Hotel managers can use the psychological process presented in this paper to better understand how FLEs make knowledge-hiding decisions in the workplace. Furthermore, specific measures are suggested to reduce FLEs’ knowledge-hiding behaviors in each stage of their knowledge exchange decision process.

Originality/value

This paper uncovers the psychological process of individuals’ decision-making regarding hiding knowledge from others in the hotel context, thus increasing the understanding of the rationale of FLEs’ knowledge hiding behaviors from the perspective of bounded-rational decision theory.

Abstract

Purpose

Hydrostatic thrust bearing is a key component of the vertical CNC machining equipment, and often results in friction failure under the working condition of high speed and heavy load. The lubricating oil film becomes thin or breaks because of high speed and heavy load and it affects the high precision and stable operation of the vertical CNC machining equipment; hence, it is an effective way of avoiding friction failure for achieving the oil film shape prediction

Design/methodology/approach

For the hydrostatic thrust bearing with double rectangular cavities, researchers solve the deformation of the friction pairs in hydrostatic bearing by using the computation of hydrodynamics, elasticity theory, finite element method and fluid-thermal-mechanical coupled method. The deformation includes heat deformation and elasticity deformation, the shape of gap oil film is got according to the deformation of the friction pairs in hydrostatic bearing, and gets the shape of gap oil film, and determines the influencing factors and laws of the oil film shape, and achieves the prediction of oil film shape, and ascertains the mechanism of friction failure. An experimental verification is carried out.

Findings

Results show that the deformation of the rotational workbench is upturned along its radial direction under the working condition of high speed and heavy load. However, the deformation of the base is downturned along its radial direction and the deformation law of the gap oil film along the radius direction is estimated; the outer diameter is close but the inner diameter is divergent wedge.

Originality/value

The conclusion can provide a theoretical basis for the oil film control of hydrostatic thrust bearing and improve the stability of vertical CNC machining equipment.

Abstract

Purpose

The purpose of this paper is to examine the influence of clients' trust, opportunism and adaptation on contractual (non)cooperation with a mediating role of coordination in the construction industry.

Design/methodology/approach

A questionnaire was used to collect data from employees of the Pakistani construction industry. Smart partial least square (SmartPLS) has been used for analyzing the data of 270 respondents from construction projects.

Findings

The results of the SmartPLS indicate that (1) Trust and contract coordination positively while opportunism negatively influence contractor's contractual cooperation. (2) Contract adaptation and contract coordination positively influence the noncontractual cooperation of the contractor. (3) Moreover, contract coordination positively mediates the relationship between trust and noncontractual cooperation, but negatively mediates the relationship between opportunism and contract adaptation and noncontractual cooperation.

Practical implications

The findings of this research suggest several policy implications for administrative authorities, project managers and policymakers. These authorities need to focus on clients' trust, opportunism and adaptation because these factors significantly influence contract coordination and cooperation in the construction industry. Emphasizing these factors will enable project managers to gain economies of scale and mitigate project failure.

Originality/value

To the best of the authors’ search and knowledge, they did not find any study examining the mediating role of coordination between trust, opportunism, adaptation and cooperation in the construction industry. Hence, the present study advances their understanding in the field of project management and construction business.

Abstract

Purpose

This article extends knowledge of market orientation (MO) and strategic collaboration by analyzing MO-collaborations in the context of firm performance of small- and medium-sized enterprises (SMEs).

Design/methodology/approach

A proposed framework built on the Knowledge and resource-based theory was tested using Structural Equation Modelling with data collected from 171 SMEs.

Findings

This research study supported the direct impact of market orientation on performance as well as the mediating role of collaboration in this focal relationship and assumed it would have a significant role in SME’s performance.

Practical implications

These findings have noteworthy implications for managers. Managers can focus on potential collaboration in order to acquire the needed assets. Owners-mangers should closely evaluate the FTAs, economic corridors, and regional cooperation agreements like BRI as these sources can lead them to collaboration with international partners. Additionally, it provides insight for entrepreneurs, business practitioners, and stakeholders of SMEs that are already operating or plan to increase their market share.

Originality/value

The study findings give interesting bits of knowledge to academia, entrepreneurs, and small- and medium-sized enterprises (SMEs). Given that market orientation and collaboration must proceed in parallel to improve firm performance, Assets like MO provide valuable knowledge and information about partners, which will lead to further valuable information to help the SME succeed. This study further extend the KBV theory recommendation that information and knowledge on collaboration works better and integration will be more successful in ‘resource rich’ firms.

This study aims to systematically reveal the complex interaction between uncertainty and the international commodity market (CRB).

Abstract

Purpose

This study aims to systematically reveal the complex interaction between uncertainty and the international commodity market (CRB).

Design/methodology/approach

A composite uncertainty index and five categorical uncertainty indices, together with wavelet analysis and detrended cross-correlation analysis, were used. First, in the time-frequency domain, the coherency and lead-lag relationship between uncertainty and the commodity markets were investigated. Furthermore, the transmission direction of the cross-correlation over different lag periods and asymmetry in this cross-correlation under different trends were identified.

Findings

First, there is significant coherency between uncertainties and CRB mainly in the short and medium terms, with natural disaster and public health uncertainties tending to lead CRB. Second, uncertainty impacts CRB more markedly over shorter lag periods, whereas the impact of CRB on uncertainty gradually increases with longer lag periods. Third, the cross-correlation is asymmetric and multifractal under different trends. Finally, from the perspective of lag periods and trends, the interaction of uncertainty with the Chinese commodity market is significantly different from its interaction with CRB.

Originality/value

First, this study comprehensively constructs a composite uncertainty index based on five types of uncertainty. Second, this study provides a scientific perspective on examining the core and diverse interactions between uncertainty and CRB, as achieved by investigating the interactions of CRB with five categorical and composite uncertainties. Third, this study provides a new research framework to enable multiscale analysis of the complex interaction between uncertainty and the commodity markets.
