Public Private Partnership (PPP) projects have attracted wide attention from academia and industry over the past 20 years, however, they been plagued by certain factors. This study identified, classified, evaluated success factors that may affect PPP for achieving sustainability. First, a list of 32 critical were categorized into 3 groups, then questionnaire survey was conducted, with 108 responses received experts, researchers, project managers in China. Second, using fuzzy synthetic...

Construction industries have poor cost performance in terms of finishing projects within a budget. A fuzzy model for evaluating the critical factors overrun construction China is developed by identifying, classifying and ranking industries. Sixty-five are identified classified into four clusters (project macro, project management, environment, core stakeholders) through detailed literature review process discussion with experts from Chinese industry. questionnaire survey was conducted data...

Though a relatively large number of studies on sustainable project governance (SPG) have been undertaken, the existing corpus literature is bereft comprehensive review paper that scientometrically analyses materials published hitherto and puts forward research gaps corresponding future works to be conducted. To fill this knowledge gap, study undertakes bibliometric scientometric analysis by meticulously delving into relevant body reported in different databases. From results obtained using...

The purpose this paper develop hierarchy risks from perspective contractor, analyze mechanism between risks. also aims further distinguish difference impact degree risks, provide reference...

Purpose Inefficiency dilemmas in project governance are caused by various risks arising from the characteristic of construction supply chain projects, such as poor performance, conflicts between stakeholders and cost overrun. This research aims to establish a fuzzy synthetic evaluation (FSE) model analyze risk factors. Corresponding mitigation strategies provided facilitate improvement performance ongoing projects. Design/methodology/approach A literature review is utilized reveal...

Purpose This study aims to examine the impacts of formal and informal hierarchical governances (HGs) on performance mega-projects mediating role contractor behavior (i.e. perfunctory consummate behaviors) in these relationships. Design/methodology/approach A total 375 valid data entries from managers representing were analyzed through path analysis. Findings Both HGs exert positive effects mega-projects. While HG positively affects behavior, only. Contractor mediates relationship between...

Intra‐organization and inter‐organization collaboration governance are becoming increasingly important for megaprojects. Different stakeholders form intricate links in a network structure. This study explores the role effect of hybrid on complex projects, such as urban rail transit projects. included conducting questionnaire survey with 116 professionals from organizations involved projects adopting structural equation modelling to analyze data. The results analyzed levels intra‐organization...

At present, the construction industry in China has problems such as low production efficiency, technical management efficiency of project, delayed delivery, budget overruns, and unreasonable risk allocation. Value can address these issues by enhancing value projects China, reducing costs, ensuring significant investment returns. This study uses literature analysis to identify critical obstacles adopting questionnaires surveys, structural equation modeling, factor prioritize management. What...

Abstract In this paper, we discuss the strong convergence of viscosity approximation method in Hilbert spaces relatively to computation fixed points an operator ϱ -strictly pseudononspreading. Under suitable conditions, some theorems are proved. Our work improves previous results for nonspreading mappings.

Identifying the potential risks and their influencing factors in hosting sports mega-events can effectively reduce probability of accident occurrence future. However, traditional risk identification primarily focuses on investigating these affecting each category individually ignores interaction risks, which leads to poor performance management efficiency. As such, this study first collects a list for by means content analysis using grounded theory, original data comes from 26 research...

Purpose Megaprojects contribute greatly to China’s socio-economic development. However, the diverse stakeholders of megaprojects tend be prone conflict and plunge project into lower performance than expected. This study aims investigate (1) optimal supervision mechanism under direct owner (2) indirect owner, with involvement integrated construction consultancy (ICC) in considerations impact collusion between ICC general contractor on efficiency. Design/methodology/approach applies...

We introduce an iterative method for finding a common element of set fixed points nonexpansive mappings, the solutions finite family variational inclusion with set‐valued maximal monotone mappings and inverse strongly mixed equilibrium problem in Hilbert spaces.

In this paper, we consider and analyze two viscosity iteration algorithms (one implicit one explicit) for finding a common element of the solution set mixed equilibrium problem Γ split feasibility in real Hilbert space. Furthermore, derive strong convergence algorithm to an under mild assumptions.

In view of the fact that traditional value engineering theory cannot meet current situation modern project evaluation, this study enriches evaluation system by means literature research and semi-structured interview. On basis "Value for project", two level-one indexes, people" economy" are added. Based on data obtained from questionnaire survey factor analysis SPSS software, secondary tertiary indexes obtained. Finally, is established, which includes three first-level indicators, ten...

As an urban infrastructure, rail transit has the advantages of high efficiency, environmental protection, punctuality and dense stations, gradually becoming backbone public transport. However, in construction operation process, negative effects such as policy change, extended period, overdraft quality defects have become key obstacles to sustainable development transit.
