Abstract

The paper presents a virtual design and assembly system (VDAS) developed in a virtual reality (VR) environment. The VDAS is a VR‐based engineering application which allows engineers to design, modify and assemble mechanical products. As a prototype, this system has a knowledge‐based library of standard mechanical fastening parts, so a great deal of work is reduced during the product modeling stage. Besides, product models can be directly inserted or modified with a friendly user interface in the immersive VR environment. In order to reach the target of virtual design and integrate VR and computer aided design, the system adopts the variational design approach, so a product model has not only the geometric information, but also variation information and even assembly match information. Finally, the VDAS has the function of assembly planning, and several interactive manipulations, such as part modification, assembly plan verification and modification, have been realized.

Abstract

Assembly is a necessary and important part of any manufacturing process. Computer aided production engineering allows production engineers to create an on‐screen virtual manufacturing environment which graphically displays and simulates actual manufacturing processes. This is an attempt to analyse the assembly process for a computer mouse, using both the Boothroyd and Dewhurst design for assembly (DFA) and Tecnomatix’s Dynamo software package. A mouse designed in Unigraphics has been the product considered and the assembly process has been analysed. Some of the steps involved in the analysis are explained in detail and the observations and results are discussed along with redesign suggestions. These software systems can help identify some of the technical problems that can possibly be encountered in real life production and can effectively be used to guide the design process. Product assembly, analysis and visualization, which are the prime features of the software in use, enable us to improve the design and enhance the features of products at the conception and design stage itself. This can be a critical factor for maintaining a competitive edge in the fast growing industry today.

Abstract

Purpose

Extreme hot environments are prevalent in many occupational settings, and facilities management workers are no exception. Wearing suitable cooling garment is a useful means to alleviate heat strain and improving performance at heat exposure. This paper aims to evaluate the effectiveness and applicability of the cooling vest across four selected fields (i.e. construction, outdoor cleaning and horticulture, kitchen work and work involved manual handling at the airport) and identify the shortcomings of the cooling vest used by the participating workers.

Design/methodology/approach

This study adopted a two-phase design: a quantitative questionnaire survey followed by qualitative in-depth interviews.

Findings

A remarkable physical strain alleviation (PSA) of 21.1 per cent (14.8 per cent in construction, 18.8 per cent in horticulture and cleaning, 27.4 per cent in kitchen and catering and 26.5 per cent in airport apron service) is achieved by the use of cooling vest in four industries. Despite the success of PSA, several shortcomings of the cooling vest were identified: easily stained color, heavy weight, short cooling time, inflexibility that presents a hazard around moving equipment, lack of industry-specific design, nondurable and thick fabric with poor permeability.

Originality/value

The findings of the current study do not only confirm the effectiveness of the cooling vest in alleviating heat strain and physical strain but also identify the major shortcomings upon which further improvements can be made.

Abstract

Purpose

The purpose of this paper is to advance supply chain network theory by applying theoretical and empirical developments in complex network literature to the context of supply chains as complex adaptive systems. The authors synthesize these advancements to gain an understanding of the network properties underlying efficient supply chains. To develop a suitable theory of supply chain networks, the authors look to mirror the properties of complex network models with real‐world supply chains.

Design/methodology/approach

The authors review complex network literature drawn from multiple disciplines in top scientific journals. From this interdisciplinary review a series of propositions are developed around supply chain complexity and adaptive phenomena.

Findings

This paper proposes that the structure of efficient supply chains follows a “scale‐free” network. This proposal emerges from arguments that the key properties of efficient supply chains are a short characteristic path length, a high clustering coefficient and a power law connectivity distribution.

Research limitations/implications

The authors' discussion centres on applying advances found in recent complex network literature. Hence, the need is noted to empirically validate the series of propositions developed in this paper in a supply chain context.

Practical implications

If efficient supply chains resemble a scale‐free network, then managers can derive a number of implications. For example, supply chain resilience is derived by the presence of hub firms. To reduce the vulnerability of supply chains to cascading failures, it is recognized that managers could build in redundancy, undertake a multi‐sourcing strategy or intermediation between hub firms.

Originality/value

This paper advances supply chain network theory. It offers a novel understanding of supply chains as complex adaptive systems and, in particular, that efficient and resilient supply chain systems resemble a scale‐free network. In addition, it provides a series of propositions that allow modelling and empirical research to proceed.

Abstract

Purpose

This paper aims to explore the perceptual differences on the factors that contribute to the successful management of public-private partnership (PPP) projects at the operational stage among stakeholders.

Design/methodology/approach

An international questionnaire survey was conducted with purposively sampled PPP experts from the private, public and academic sectors. Survey responses were analyzed using Kendall’s coefficient of concordance (W), mean score ranking analysis, Kruskal–Wallis test and Mann–Whitney U test.

Findings

The research findings show that each stakeholder group considers an efficient and well-structured payment mechanism as the most important operational management critical success factor (CSF). Moreover, the public sector considers open and constant communication among stakeholders as the second most important CSF, whereas the private and academic sectors consider effective operational risk management and well-structured legal dispute resolution mechanism, respectively. Further analysis using non-parametric tests (i.e. Kruskal–Wallis and Mann–Whitney U statistics) reveal significant differences in the importance of three operational management CSFs – “open and constant communication among stakeholders”, “effective changes of shareholdings in private consortium” and “stable macroeconomic indicators”.

Research limitations/implications

The generalizability of the research findings is limited considering the low sample size and non-participation of users/general public in the study. Hence, it is recommended that future research should be conducted in a specific country using both face-to-face and email questionnaire distribution approaches. This would likely increase the response rate and facilitate the inclusion of the general public/users.

Originality/value

The results of this study highlight and provide significant insights into how different PPP stakeholders perceive the critical conditions that are required to ensure the operational efficiency of PPP projects. This would, therefore, enable a better cooperation and collective effort from all stakeholders towards achieving the overall project success. In addition, the study offers new and additional CSFs which would enhance the comprehensiveness of the existing list of CSFs for the general implementation of PPP projects.

Abstract

Purpose

Public-private partnerships (PPPs) offer governments an opportunity to access private capital and skills to build or upgrade, operate and manage public water infrastructure services hitherto provided and run by the public sector. Access to private finance speeds up the provision of public water services in developing countries, where many governments face budgetary constraints. However, the water sector attracts the least investment flows in developing countries, well below other infrastructure sectors. This paper aims to present the results of an investigation of critical success factors (CSFs) required for attracting the private sector in water supply projects.

Design/methodology/approach

A structured questionnaire survey of international PPP expert opinions was conducted.

Findings

Analysis results show that the CSFs for attracting the private sector to water PPPs include political commitment from elected leaders toward PPPs for water supply; existence of a dedicated PPP unit; strong and competent public water authority; adequate fiscal capacity of a national/subnational authority; public acceptance and support of involvement of the private sector in water services; a well-designed PPP contract; existence of enabling policy and legal frameworks to support water PPPs; and profitability of water supply project(s) to attract investors and lenders. Agreement analysis also indicates a strong to very strong agreement on the significance and rankings of the CSFs.

Originality/value

The research findings provide an insight into a number of important issues to enable greater private participation in water supply projects, most of which aim at reminding governments of some key areas that need reform and enabling greater commitment among them to undertake such reforms. Given the limited empirical research on CSFs for attracting private participation, this research makes a contribution to the body of knowledge about private involvement in the water sector of developing countries.

Abstract

Purpose

Management control is needed in international joint ventures (IJVs) for successful management and performance. While IJV management control and performance concept has been widely explored, in the construction sector, the core understanding of the design of the two concepts is still lacking. This has resulted in the neglect of important questions and directions for research and practice improvement. This study aims to conduct a critical survey of prior studies addressing the conceptualization of management control and performance in IJVs and to propose a framework for studying the performance implications of management control in international construction joint ventures (ICJVs).

Design/methodology/approach

Using Scopus database and search terms, a systematic desktop search was conducted to retrieve empirically related peer-reviewed papers for this study.

Findings

Drawing on the transaction cost, institutional and relational logic, the first inclusive hypothetical model for studying the relationship between different dimensions of management control mechanism and multiple performance criteria in ICJVs is presented. The model proposes a measurement method for both the management control and performance and explains how they can be established in ICJVs.

Practical implications

The proposed framework provides a methodology to understand the dynamics of management control and performance implications in ICJV. Specifically, uncovering the critical paths will assist ICJV frontliners to approach management control in a more holistic and systematic way to promote achievement of ICJV goals.

Originality/value

The study gives a firm ground to the construction industry, which is accurate and educational for related fields concentrating on several other forms of cooperative relationships.

Abstract

Purpose

The increasing demand for public infrastructure has caused a rise in the global adoption of the public–private partnership (PPP) concept. However, over the past years, most of the developing countries have failed to attract more private investments as realised in the developed countries. This paper aims to investigate the critical factors that attract private investments in the PPP markets of developing countries.

Design/methodology/approach

An empirical questionnaire survey was conducted with targeted international PPP experts from the academic and industrial sectors. The inter-rater agreement analysis, mean score ranking and Mann–Whitney U test were used to analyse the survey responses.

Findings

Results indicate that the three most critical factors are political support and acceptability for PPPs, government positive attitude towards private sector investments and political stability. On the other hand, factors including government guarantees, competent PPP unit and tax rebate on imported equipment are of low importance. The Mann–Whitney U test reveals that experts from the academic and industrial sectors view the importance of three factors differently: adequate public sector experience in PPP, government providing guarantees and government providing tax rebate on imported equipment.

Originality/value

The research outputs contribute to the existing but limited knowledge on PPP practices in developing countries by providing empirical evidence and cross-cultural perceptions on the conditions that are critical to the expansion of PPP markets in developing countries. It is therefore expected that governments and policymakers seeking to adopt the PPP concept would take into consideration the results and implications to enhance PPP growth.

Abstract

Looks at consumer research in Greater China including Mainland China, Hong Kong and Taiwan. Maps out the contributions within this area and guides future research. Examines the state of the art over the 1979‐97 period, with particular emphasis on the topics that have been researched, the extent of the theory development in the field and the methodologies used in conducting research. Uses content analysis to review 75 relevant articles. Suggests that, while a considerable breadth of topics have been researched, there remains much to be done, there is further room for theoretical development in Chinese consumer behaviour studies; and the methodologies used need improvement and further refinement.
