Abstract

Purpose

The integration of e‐business and supply chain enables seamless information flow from suppliers to customer service network via the internet. It also enables better‐coordinated materials flow from customer order to production, storage, distribution and delivery. The purpose of this paper is to describe the work that leads to the realisation of a hierarchical model for e‐supply chain coordination and optimisation.

Design/methodology/approach

The model is based on an e‐business information flow network in order to respond rapidly to the dynamics of e‐supply chain and market. It can be used to realize management level strategies, and facilitate the planning and control of detailed operation schedules of supply chain units in an e‐supply chain environment. Three main modules are discussed. They are routing and sequence optimiser (RSO) with the aid of a GA and TS‐based multiple population search strategy (MPSS); supply chain virtual clustering (SCVC) based on fuzzy virtual clustering; and supply chain order scheduling (SCOS) using an agent‐based distributed scheduling system.

Findings

These modules enable: the generation of preferred routings, transportation modes and work order plan under such constraints as customer service level, cycle time and cost; the formation of supply chain's unit‐transportation‐work order families using a clustering approach to down‐size supply chain problems and increase computation efficiency; and the integration of scheduling with supply chain optimisation in order to facilitate the control of a supply chain with the aid of an agent‐based distributed scheduling approach.

Originality/value

This paper proposed a hierarchical model for e‐supply chain coordination and optimisation that is capable to solve large‐scale problems. A MPSS using GA and TS was depicted in detail to expedite the RSO.

Abstract

A printed circuit board (PCB) assembly consists of a circuit board and a variety of components in different shapes and sizes placed at specific locations on the board. They are used extensively in a variety of products by many industries today. These products include, for example, computer terminals, televisions, electronic instruments, and process controllers. There are many types and models of automatic machines available for placing components on the boards. The component placement operation consists of all steps necessary to remove a component from its packaging materials and mount it onto the PCB. The components are supplied either from a set of feeders, magazines or matrix trays. Because of the extreme accuracy required, automatic equipment is mandatory for all but the smallest production volumes.

Abstract

Research effort to integrate an analysis module of inductive field into an eddy current NDT system to realise a hybrid technique, which is capable of automatically analysing the inductive field so as to set up the optimum parameters for the system, has not been well addressed. This paper describes the work that leads to the realization of such a hybrid technique. First, two finite element models are described. Next, an analytical algorithm based on these models is proposed. By integrating the algorithm into an eddy current NDT system, a smart hybrid technique can be realized. This is beneficial in setting up relevant parameters such as the working frequencies and the detection distance. Thus, the test precision can be improved. Taking a cylindrical inductive sensor as an example, some calculation results are provided to illustrate the analysis of the inductive field produced in an eddy current NDT system.

Abstract

Purpose

Lean construction looks into the possibility of bringing successful lean production theories into the construction industry. It was believed that lean production principles could also be influenced by the essence of military strategies, specifically that of Sun Tzu's Art of War (ST) when these were introduced many years ago. This study looks into the practices of lean construction in the industry and the similarities in the two sets of statements from lean construction principles and Sun Tzu's strategic principles.

Design/methodology/approach

Surveys and interviews of 40 project managers in the construction industry were conducted.

Findings

The study suggests that there are some agreements between lean construction principles and Sun Tzu's strategic principles.

Research limitations/implications

This study raises the interesting question of whether the origin of lean construction principles can be traced to the strategic principles formulated by Sun Tzu some 2,500 years ago.

Practical implications

It is recommended that the strategic principles formulated by Sun Tzu be tapped upon for the further extension of lean principles (LP) in construction.

Originality/value

The value of this paper lies in its reflections of ST to better understand the possible origin of current lean construction principles and practices.

Abstract

Purpose

This paper aims to propose a direction for rejuvenating the declining Ipoh Old Town through a conservation-based approach.

Design/methodology/approach

Recommendations for revitalisation are based on comparison between the local government's development proposals and historical study of revitalisation initiatives undertaken in neighbouring countries.

Findings

The review has found that the revitalisation of Ipoh should be more towards servicing the needs of its residents than to gain from tourism development.

Practical implications

Findings of the review have blurred the distinction between purist and ameliorist stances of conservation and suggest that the policy development should be a partnership of all stakeholders, vested with powers to implement.

Originality/value

This paper provides an insight into urban regeneration for smaller, more local-dependent historic towns.

Abstract

Purpose

The purpose of this paper is to present defects reported by cooperative owners, and to determine the relationship between building characteristics, developer’s/contractor’s company size and defect type.

Design/methodology/approach

The analysis is based on defects reported by board members of cooperatives in Sweden through a survey questionnaire. The 1,563 questionnaires were posted by regular mail to the boards of cooperatives for buildings. The current research presents results from analysis of responses from 394 regular residential projects constructed between 2006 and 2013. The responses represent owners’ experience from a total 1,107 buildings.

Findings

Findings presented in this study indicate that building quality might be one of the factors contributing to the energy gap. The analysis indicates that the most severe problems reported by cooperatives are issues related to building envelope, particularly shortcomings in the function of windows, issues related to the function of the balcony and cracks in the facade and leakage caused by rain water. The results show that the building quality differs depending on developers’ size, measured by number of employees. The authors have also found a significant relationship between reported defects and location expressed by size of the city/municipality.

Originality/value

The discussion on newly constructed residential buildings has been dominated by the perspective of professionals (inspectors) and contractors (or developers) rather than of the owners/users themselves. This study presents findings from the owners’ perspective, thus contributing the owners’ viewpoint to the debate on building quality.

Abstract

Purpose

The purpose of this paper is to employ an integrated approach of interpretive ranking process (IRP) and system dynamics (SD) for modelling the key risk factors for a typical construction project.

Design/methodology/approach

The risk parameters and performance measures applicable in the construction industry have been identified through extensive literature review and discussions with experts from the construction industry. Based on the literature review, a questionnaire was designed and 64 responses were considered. The list of 20 risk parameters and 32 performance measures relevant for a construction industry is reduced to five risk factors and five performance measure factors using factor analysis. IRP modelling is employed to examine the contextual relationships among risk factors and to rank them with respect to performance measure factors. Subsequently, the results of IRP model were utilised as inputs to SD analysis. The SD analysis is conducted for two models, namely, risk factor model and risk variable model to understand the impact of interventions offered by project management team on risk reduction and mitigation.

Findings

The developed IRP model shows that the risk factor dimension “construction management” has a high likeliness to occur during the construction phase.

Research limitations/implications

The research demonstrates an application of proposed approach for a typical construction environment and hence the results cannot be generalised.

Originality/value

This research addresses real life complexities in construction project by modelling critical risk factors using an integrate approach of IRP and SD. The proposed approach would facilitate project managers to devise appropriate risk mitigation strategies for a construction project.
