Abstract

Due to the increasing size and complexity of construction projects, construction engineering and management involves the coordination of many complex and dynamic processes and relies on the analysis of uncertain, imprecise and incomplete information, including subjective and linguistically expressed information. Various modelling and computing techniques have been used by construction researchers and applied to practical construction problems in order to overcome these challenges, including fuzzy hybrid techniques. Fuzzy hybrid techniques combine the human-like reasoning capabilities of fuzzy logic with the capabilities of other techniques, such as optimization, machine learning, multi-criteria decision-making (MCDM) and simulation, to capitalise on their strengths and overcome their limitations. Based on a review of construction literature, this chapter identifies the most common types of fuzzy hybrid techniques applied to construction problems and reviews selected papers in each category of fuzzy hybrid technique to illustrate their capabilities for addressing construction challenges. Finally, this chapter discusses areas for future development of fuzzy hybrid techniques that will increase their capabilities for solving construction-related problems. The contributions of this chapter are threefold: (1) the limitations of some standard techniques for solving construction problems are discussed, as are the ways that fuzzy methods have been hybridized with these techniques in order to address their limitations; (2) a review of existing applications of fuzzy hybrid techniques in construction is provided in order to illustrate the capabilities of these techniques for solving a variety of construction problems and (3) potential improvements in each category of fuzzy hybrid technique in construction are provided, as areas for future research.

Abstract

Purpose

The growth of the Chinese economy has resulted in a significant increase in construction and demolition waste (CDW), and regional differences in CDW generation are gradually increasing. The purpose of this study is to investigate the regional differences in CDW generation and the driving factors that influence CDW generation in different areas of China. To provide a systematic advisement for local governments to select the appropriate policy, reduce CDW generation.

Design/methodology/approach

The generation of CDW was calculated by region, based on the area estimation method, from 2005 to 2018. The relationship between CDW generation and economic development, and the driving factors of CDW generation in different regions of China, was investigated using the environmental Kuznets curve (EKC) model and the STIRPAT theoretical model.

Findings

CDW generation of China increased at the average annual growth rate of 10.86% from 2005 to 2018. The main areas of CDW generation were concentrated in the eastern and central regions, while the proportion of CDW generation in the northeast region decreased gradually, and the changes varied significantly across different regions. The EKC between CDW generation and economic development was established for the whole country, North China, Northeast China, East China, Central South China, Southwest China and Northwest China. Three main factors based on the STIRPAT theoretical model were identified and explained into a framework to reduce CDW generation. The results provided a useful theoretical basis and data support guide for devising effective policies and regulations for the Chinese context.

Practical implications

The findings from this study can ultimately support policymakers and waste managers in formulating effective policies for waste management strategies and CDW-specific legislation. Additionally, it can help the coordinated reduction of CDW generation across regions in China and can support construction enterprises (in their development strategies), similar developing economies and foreign firms planning to operate in China.

Originality/value

This study contributes to the field through the STIRPAT model on driving factors of CDW generation in the Chinese context, in different regions.

Abstract

Purpose

The purpose of this paper is to examine the relationship between open innovation (OI) and innovative performance, and to explore the moderating effect of knowledge structure, including component knowledge and architectural knowledge, on this particular relationship.

Design/methodology/approach

The proposed model was tested with regression analysis of data collected through a questionnaire survey of 231 employees of Chinese manufacturing firms.

Findings

The findings indicate that inbound OI is positively related to innovative performance and that outbound OI has an inverted U-shaped effect on innovative performance. By presenting empirical evidence of the moderating effects of component and architectural knowledge, our analysis of results demonstrates that the strong alignment between knowledge structure and OI results in superior innovative performance.

Originality/value

This study addresses the controversial issues brought up by previous studies with findings of an inverted U-shaped effect of outbound OI on innovative performance. By exploring the moderating effect of knowledge structure, the authors provide insights into how internal contextual factors in relation to organizational knowledge can affect the efficacy of the inbound and outbound OI on innovative performance.

Abstract

Purpose

The purpose of this paper is to provide a theoretical account of how firms make choices between dynamic capability-based and ad hoc problem-solving approaches toward strategic change.

Design/methodology/approach

A model has been developed to answer the questions of how and under what conditions firms develop appropriate approaches to handle strategic change.

Findings

Drawing upon structural inertia theory (SIT) and the resource-based view (RBV), the model predicts that firms, regardless of their age and size, are more likely to adopt an ad hoc problem-solving approach to handle change in both highly dynamic and low-dynamic environments. However, in moderately dynamic environments, a dynamic capability-based approach may be more appropriate, depending on which theoretical logic (SIT or RBV) the decision is made.

Originality/value

The paper builds on the useful distinction made by Winter (2003) in terms of the ways to handle organizational change and extends the recent research on temporary vs sustainable competitive advantages to investigate how firms tackle strategic change within the contexts of both environmental dynamism and organizational attributes.

Abstract

Purpose

Managing tacit knowledge effectively and efficiently is a huge challenge for organizations. Based on the social exchange and self-determination theories, this study aims to explore the role of social interactions in motivating employees' willingness to share tacit knowledge (WSTK).

Design/methodology/approach

The study used a survey approach and collected data from 228 employees in service and manufacturing organizations.

Findings

Interactional justice and respectful engagement are positively related to WSTK. The perceived cost of tacit knowledge sharing (CostTKS) partially mediates the relationship between interactional justice and WSTK. Respectful engagement moderates the negative relationship between interactional justice and the perceived CostTKS.

Research limitations/implications

The study advances the understanding of the role of social interaction in facilitating employee WSTK by integrating the direct and intermediate relationships involving the effect of supervisor's interactional justice and peers' respectful engagement and employee perceived CostTKS on WSTK.

Practical implications

The findings have important practical implications for organizations as these suggest how organizations can help tacit knowledge holders experience less negative and more supportive behaviors when they engage in voluntary TKS.

Originality/value

This study examines the effect of both vertical and horizontal work-related interactions on perceived CostTKS and sequentially on WSTK, thereby extending existing literature.

Abstract

Purpose

Firms often struggle with opportunistic behavior from supply chain partners. Relying on Transaction Cost Economics and its extensions, this study developed a conceptual model theorizing the antecedence, consequences and conditional factors of opportunism within a buyer–supplier–supplier triadic relationship.

Design/methodology/approach

This study employed a cross-sectional survey data collected from 200 U.S. firms. The collected data were analyzed with SPSS and AMOS, the two statistical software, for reliability, validity, confirmatory factor analyses and structural equation modeling.

Findings

First, opportunism negatively influences operational performance and business performance, and such an effect is fully mediated by relationship stability. Second, this study classified power asymmetry as asymmetrical power discrepancy and asymmetrical power advantage with these two forms playing different roles in influencing opportunism. Results indicate that asymmetrical power discrepancy induces opportunism while asymmetrical power advantage strengthens the negative influence that opportunism has on relationship stability. Additionally, the mediated moderating effect of asymmetrical power advantage by relationship stability is confirmed.

Originality/value

The results provide significant academic and managerial insights that can guide managerial efforts in distinguishing types of power asymmetry, controlling opportunism and further mitigating the consequences of opportunism within a triadic relationship.

Abstract

Purpose

The main purpose of this study is to enhance bio-tribological properties of Ti6Al4V and the surface-modified layers of Ni+/N+-implanted Ti6Al4V alloy, bionic texturing was done on Ti6Al4V surface.

Design/methodology/approach

The phase compositions and nano-hardness of the surface-modified layers of the samples have been analyzed by X-ray diffractometer and Nano Indenter, respectively. This paper has conducted bio-tribological tests under artificial saliva, sodium hyalurate and sodium hyalurate +γ-globulin by micro tribology multifunction tribometer, with ZrO2 ball/modified layer as the friction pair. S-3000N scanning electron microscope has been used to analyze the morphology of the surface-modified layers and scratches of the ones after the bio-tribological tests.

Findings

The results show that the surface-modified layers were mainly composed of Ti2Ni and Ti2N. Moreover, bionic texturing can obviously increase the contents of Ti2Ni and Ti2N that were formed on the surface of Ni+/N+-implanted Ti6Al4V alloy, and enhance the nano-hardness of the surface-modified layers. It could also reduce the friction coefficients of the surface-modified layers, and render the modified layers more wear-resistant.

Originality/value

The surface bio-tribological properties of Ti6Al4V have been enhanced by ion implantation technique and bionic texturing in this paper; this provided a new method for the research of related fields.

Abstract

Purpose

Large deformation problems are frequently encountered in various fields of geotechnical engineering. The particle finite element method (PFEM) has been proven to be a promising method to solve large deformation problems. This study aims to develop a computational framework for modelling the hydro-mechanical coupled porous media at large deformation based on the PFEM.

Design/methodology/approach

The PFEM is extended by adopting the linear and quadratic triangular elements for pore water pressure and displacements. A six-node triangular element is used for modelling two-dimensional problems instead of the low-order three-node triangular element. Thus, the numerical instability induced by volumetric locking is avoided. The Modified Cam Clay (MCC) model is used to describe the elasto-plastic soil behaviour.

Findings

The proposed approach is used for analysing several consolidation problems. The numerical results have demonstrated that large deformation consolidation problems with the proposed approach can be accomplished without numerical difficulties and loss of accuracy. The coupled PFEM provides a stable and robust numerical tool in solving large deformation consolidation problems. It is demonstrated that the proposed approach is intrinsically stable.

Originality/value

The PFEM is extended to consider large deformation-coupled hydro-mechanical problem. PFEM is enhanced by using a six-node quadratic triangular element for displacement and this is coupled with a four-node quadrilateral element for modelling excess pore pressure.

Abstract

Purpose

The purpose of this paper is to explore online discussions about the 2014 World Cup on the Chinese social media platform Sina Weibo. Because China did not qualify for the World Cup, the study focusses on the role of online discussions surrounding a worldwide international event from an outsider perspective. Doing so will uncover not only the depth of dialogue surrounding issues of nation and sport, but – perhaps more importantly – also aid in uncovering the utility of online platforms in creating online communities even among presumed outsiders.

Design/methodology/approach

A content analysis of the discussions on Sina Weibo is used to identify differences between fanship comments and non-fanship comments in terms of the focus of the content and the degree of valence.

Findings

Overall, fans were more likely than non-fans to use positive valence in their comments to enhance the value of the World Cup. Moreover, fans were also more likely to discuss topics closely related to the event itself, such as teams, athletes, and factual information/news about the World Cup, establishing identification with in-group participants. Moreover, the findings also imply important insight regarding electronic commerce opportunities.

Originality/value

This paper is among the first to investigate the online discussions about World Cup in China. Theoretically, this paper provides a comprehensive framework to examine the online discussions of mega-sporting events in China based on theories of social identity theory and nationalism. Practically, it provides baseline data for the sports industry and public relation practitioners to promote a sports event when the direct nationalistic interests are absent. Moreover, it also aids in uncovering the substantial changes in sports-related communication, experiences, and mediated participation.

Abstract

Purpose

This study aims to examine the impact of the supplier's coercive and cognitive pressures on a manufacturer's green purchasing decision-making process and the resultant implications in terms of operational and environmental performances.

Design/methodology/approach

Path analysis is performed to test the hypothesized linkages.

Findings

This study finds that the supplier's coercive pressure, environmental focus and socio-cultural responsibility will lead a firm to more successful implementations of green purchasing, which, in turn, results in improved operational and environmental performances. The study findings reveal that the commercial values of green purchasing in addition to social and political obligations will promote the adoption of green purchasing in supply chain management practice.

Originality/value

This study helps business managers understand the impacts of the supplier's coercive and cognitive pressures on green purchasing and the manufacturer's resultant performances. In particular, coercive pressure is operationalized by the supplier's coercive pressure and environmental regulatory pressure, while cognitive pressure is reflected in the supplier's environmental focus and socio-cultural responsibility. This study contributes to the extant theories and enriches the literature on green purchasing.
