Abstract

Electronic packaging technologies, such as pin grid arrays, increasingly small pitch surface mount, and double‐sided assemblies are all aimed towards the highest possible product density, with improved performance. The gap between inspection effectiveness and advances made in packaging technologies is becoming larger. As efforts proceed, to learn more about critical factors influencing reliability of solder joints, it is prudent to ensure that printed wiring assembly (PWA) design rules evolve to permit the broadest range of anticipated automated inspection requirements. The range of automated inspection technologies can all be made more effective through careful design of electronics for inspection. Significant opportunities lie in both PWA layout and design, as well as electronic component design, tolerancing, and standardisation. Many inspection issues are shared, but with increased recognition of digital radiography's unique capabilities; this discussion will emphasise X‐ray inspection issues.

Abstract

Purpose

The purpose of this paper is to present a multi‐expert system that can provide designers with suggestions for improvement. The multi‐expert system can analyse a design and provide designers with ideas for changes to designs at an early stage in order to improve assembly later in the manufacturing process.

Design/methodology/approach

The whole system consists of four expert systems: computer‐aided design (CAD) expert, automated assembly expert, manual assembly expert and design analysis expert. The design analysis expert includes a sub‐system to collate the information from the assembly experts and to provide costs and advice.

Findings

The paper finds that the approach and the systems can reduce manufacturing costs and lead times.

Research limitations/implications

A knowledge‐based reckoning approach to design‐for‐assembly automation is used. The approach and systems can reduce manufacturing costs and lead times. The system can estimate assembly time and cost for manual or automatic assembly and select suitable assembly techniques.

Practical implications

The system can estimate assembly time and cost for manual or automatic assembly and select a suitable assembly technique.

Originality/value

The new system models assembly, product and process design using a natural approach for capturing intelligence. The new approach categorised automated assembly and manual assembly into separate individual experts. Intelligence and knowledge from each is captured and embedded within the individual expert that represented the process. This approach enabled greater flexibility and made the sub‐systems easier to modify, upgrade, extend and reuse.

Abstract

This paper describes an automated design system for nuclear structural components under complicated loading conditions. As a basic strategy of designing structures considering various loading conditions, the “generate and test” strategy is adopted because of simplicity and broad applicability. The object‐oriented knowledge representation technique is adopted to store knowledge modules related to design problems, while the data‐flow processing technique is utilized as an inference mechanism among the knowledge modules. As efficient design modification mechanisms, the present system utilizes two approaches, (a) an empirical approach based on experts’ empirical knowledge and the fuzzy control, and (b) a mathematical approach based on numerical sensitivity analysis. Using the present system, one can also obtain a “design window” which designates a satisfaction area for all design criteria in a design variable space. The fundamental performances of this system are clearly demonstrated through the design of a two‐dimensional model of the fusion first wall with a circular cooling channel.

Abstract

Purpose

To design a flexible integrated robotic assembly and rework (remanufacturing) cell for assembly, selective assembly and rework of advanced surface mount components (SMCs) using the generic methodology developed in this paper.

Design/methodology/approach

Manual rework procedures are investigated for all advanced SMCs. General and specific component‐related rework considerations are obtained and necessary tooling candidates for automation are determined. This is followed by determination of the specific automated rework procedure and selection of suitable tooling for automated robotic rework and generation and evaluation of design concepts.

Findings

The developed methodology, which considers the reflow tool at the centre of the development process, has worked well in designing a flexible integrated robotic assembly and rework cell.

Practical implications

This study identified the rework requirements for advanced SMCs, the essential features for rework reflow tools, criteria for comparing reflow tools, and a generic procedure for design and concept selection.

Originality/value

It provides valuable knowledge for designers of flexible integrated robotic assembly and rework cells for assembly, selective assembly and rework of advanced SMCs.

Abstract

Purpose

The main purpose of this paper is to highlight the significance of service quality factors on customer retention within the Australian traditional and automated banking contexts.

Design/methodology/approach

The relative importance of traditional and automated service quality factors on customer retention was examined with the intention of determining which indicator factors are likely to have a significant impact on customer retention. The paper then proposes a conceptual model of the relationship between service quality factors within the two contexts and customer retention. AMOS 5 was used to test for the hypothesized relationships.

Findings

All of the traditional service quality factors have positively influenced customer retention. Conversely, this paper finds that automated service quality in general has no positive significant influence on customer retention.

Research limitations/implications

This research was applied to the financial institutions in Queensland, Australia. Further testing of the proposed conceptual model across different industries and countries is needed to determine the generalisability and consistency of this study's findings.

Practical implications

The proposed model of retention prediction has the potential to help Australian bank managers to strengthen the customer‐bank relationship and, ultimately, to enhance customer retention ratios.

Originality/value

The key contribution of this paper is a conceptualisation of customer retention predictors that takes into account both traditional and automated service customer interactions with banks.

Abstract

Optimization of structural systems under reliability‐based performance constraints is an important problem at present receiving too little attention. This problem is investigated in this paper. In developing the reliability‐based optimization approach to the design of framed structures, we review first the general formulation of the deterministic optimization problem and present some of the main features of two general‐purpose deterministic optimization programs. A computer‐automated reliability‐based optimum design procedure is then presented by which the concept of reliability analysis with regard to both serviceability and ultimate performance constraints is combined with that of the minimum weight design to achieve an optimum trade‐off between the global reliability and the total cost. The procedure is feasible for application in system optimization of both steel and reinforced concrete structures.

Abstract

Purpose

A fixture is a special tool used to accurately and stably locate the workpiece during machining process. Proper fixture design improves the quality and production of parts and also facilitates the interchangeability of parts, which is prevalent in much of modern manufacturing. The purpose of this paper is to combine the rule‐based reasoning (RBR) and case‐based reasoning (CBR) method for machining fixture design in a virtual reality (VR) based integrated system.

Design/methodology/approach

In this paper, an approach combining the RBR and fuzzy comprehensive judgment method is proposed for reasoning suitable locating features and clamping features. Based on the reasoning results, a CBR method for machining fixture design is then presented.

Findings

The paper finds that the proposed system is an efficient tool for machining fixture design.

Practical implications

The proposed system enables the designers to perform fixture design with automated fixture locating method reasoning and make a new fixturing solution quickly by referencing previous design cases.

Originality/value

A VR application for machining fixture design is presented.

Abstract

Purpose

The ability to establish sustainable frameworks for creating and managing recordkeeping metadata is one of the key challenges for recordkeeping in digital and networked environments. The purpose of this article is to give an overview of the Clever Recordkeeping Metadata Project, an Australian research project which sought to investigate how the movement of recordkeeping metadata between systems could be automated.

Design/methodology/approach

The project adopted an action research approach to the research, utilising a systems development method within this framework to iteratively build a prototype demonstrating how recordkeeping metadata could be created once in particular application environments, then used many times to meet a range of business and recordkeeping purposes.

Findings

Recordkeeping metadata interoperability, like recordkeeping metadata itself, is complex and dynamic. The research identifies the need for standards and tools to reflect and have the capacity to handle this complexity.

Originality/value

This paper provides insights into the complex nature of recordkeeping metadata and the kind of infrastructure that needs to be developed to support its automated capture and re‐use in integrated systems environments.

Abstract

Purpose

Automation facilitates production activities within offsite construction (OSC) projects through computer-controlled and mechanised systems that can be programmed to deliver various products in a self-regulating sequence. Despite known benefits of automation to offsite production, the level of automation adoption in New Zealand is low. This study is an effort to understand the current status of automation within the New Zealand construction industry and to identify the barriers and enablers to its uptake.

Design/methodology/approach

This study utilises the qualitative approach of semi-structured interviews (open-ended questions). Using a referral sampling strategy (snowballing), fifteen New Zealand industry experts were interviewed, and the data collected were analysed using qualitative content analysis.

Findings

The study found that there is a weak business case for full automation. Four main categories of barriers to the uptake of automated OSC were identified, including requirement of high capital cost, lack of education about automation and OSC and non-existence of regulations to support OSC. It was noted that financial supports to the OSC sub-sector in form of subsidies, tax waivers, and enhanced leasing model could enhance the uptake of automation. Further to this more awareness about OSC's automation and regulations suitable for OSC could enhance the confidence of business owners to invest in this area.

Originality/value

Originality of this paper stems from the fact that, not much attention has been paid to investigating the uptake of automation for OSC sub-sector of construction industry in New Zealand context.
