Abstract

Current construction management programmes in higher education institutions provide students with sound technical and management knowledge. However, in the twenty‐first century, construction professionals need to be familiar with the cultural, environmental, and political factors that could affect international projects and know how to work effectively in the global arena. How to face the unique challenges due to rapidly increasing globalisation is the question that concerns construction educators around the world. However, current construction management curricula do not usually provide students with even basic training on international project management. To remedy this defect, globalisation components have been incorporated into construction management education at East Carolina University through lecture exchange, study abroad, student exchange, scholar exchange, and research exchange activities. This paper presents the international activities performed, the outcomes, and student growth in international construction management.

Abstract

Purpose

Selecting a proper project delivery system is one of the critical issues for the success of a project. This paper discusses the application of project delivery systems in China and the existing project delivery system selection methods, analyzes project objectives and indicators influencing the selection of project delivery systems, and aims at finding an appropriate method to select project delivery systems.

Design/methodology/approach

A survey was conducted by postal questionnaire and Multivariate Statistical Analysis was applied to analyze the project data. A robust model was developed to analyze the selection of project delivery systems.

Findings

The results of survey and analysis show that design‐bid‐build (DBB)/project management (DBB+PM), design‐build (DB)/engineering, procurement and construction (EPC)/Turnkey, multi‐stage DB/EPC and EP+C are commonly used in China. The differences between DBB and DBB+PM, and differences between DB/EPC and Turnkey in China are not significant. Weights of project objectives in each project delivery system and the ranking of indicators influencing the selection of project delivery systems are acquired.

Originality/value

Analysis was conducted with a robust model instead of traditional model in consideration of efficiency. This research may assist owners in Mainland China in selecting project delivery systems, improve project performance, and encourage efficiency in project delivery process.

Abstract

Purpose

This paper aims to study the issues of adaptive fuzzy control for a category of switched under-actuated systems with input nonlinearities and external disturbances.

Design/methodology/approach

A control scheme based on sliding mode surface with a hierarchical structure is introduced to enhance the responsiveness and robustness of the studied systems. An equivalent control and switching control rules are co-designed in a hierarchical sliding mode control (HSMC) framework to ensure that the system state reaches a given sliding surface and remains sliding on the surface, finally stabilizing at the equilibrium point. Besides, the input nonlinearities consist of non-symmetric saturation and dead-zone, which are estimated by an unknown bounded function and a known affine function.

Findings

Based on fuzzy logic systems and the hierarchical sliding mode control method, an adaptive fuzzy control method for uncertain switched under-actuated systems is put forward.

Originality/value

The “cause and effect” problems often existing in conventional backstepping designs can be prevented. Furthermore, the presented adaptive laws can eliminate the influence of external disturbances and approximation errors. Besides, in contrast to arbitrary switching strategies, the authors consider a switching rule with average dwell time, which resolves control problems that cannot be resolved with arbitrary switching signals and reduces conservatism.
