A design and implementation methodology for high variety electronics assembly systems

Small indigenous manufacturers of electronic equipment are coming under increasingly severe pressure to adopt a strong defensive position against large multinational and Far Eastern companies. A common response to this threat has been for these firms to adopt a 'market driven' business strategy based on quality and customer service, rather than a 'technology led' strategy which uses technical specification and price to compete. To successfully implement this type of strategy there is a need for production systems to be redesigned to suit the new demands of marketing. Increased range and fast response require economy of scope rather t ban economy or scale while the organisation's culture must promote quality and process consciousness. This paper describes the 'Modular Assembly Cascade' concept which addresses these needs by applying the principles of flexible manufacturing (FMS) and just in time (,JlT) to electronics assembly. A methodology for executing the concept is also outlined. This is called DRAMA (Design Houtirw !'or· Adopting Modular Assembly).

Universities Masters World Cup Soccer:integrated sports science research and implementation of an international masters soccer community

Ageing populations with greater wellness and athletic expectations require quality sports and active living experiences in order to increase and sustain participation levels. Responding to the diverse needs and circumstances of Masterslveterans players is a complex and multi-faceted process. While sports science contributions have been very effective at enhancing active living in a variety of youth and adult sports events, very little has been documented regarding their efficacy in events for Masterslveteran players. This paper draws upon action research to examine the growth and development of a unique Masters World Cup 6-0-side Soccer Tournament, involving representative teams from twelve nations. lntegrated sports science concepts and strategies were employed to develop quality soccer experiences. Longitudinal data suggest that fostering a community of practice is critical to the success of Masters soccer programs. In addition to critical leadership contributions, an eclectic range of age-appropriate and responsive soccer experiences are essential to ensure that Masters events meet the diverse needs and circumstances of the players.

Serious games for energy social science research

This paper proposes a set of criteria for evaluation of serious games (SGs) which are intended as effective methods of engaging energy users and lowering consumption. We discuss opportunities for using SGs in energy research which go beyond existing feedback mechanisms, including use of immersive virtual worlds for learning and testing behaviours, and sparking conversations within households. From a review of existing SG evaluation criteria, we define a tailored set of criteria for energy SG development and evaluation. The criteria emphasise the need for the game to increase energy literacy through applicability to real-life energy use/management; clear, actionable goals and feedback; ways of comparing usage socially and personal relevance. Three existing energy games are evaluated according to this framework. The paper concludes by outlining directions for future development of SGs as an effective tool in social science research, including games which inspire reflection on trade-offs and usage at different scales.

Manoeuvring towards research decline:the RAE and the decline of Britain's international research standing

Purpose: This research paper aims to examine the global trends in publishing in the leading marketing journals between 1964 and 2008, focusing on how public policy intervention in the assessment and funding of academic research has influenced Britain's relative productivity in the world's leading marketing journals. Design/methodology/approach: The method was an audit of contributions to the leading journals based on the authors' affiliation, country of origin and country in which they obtained their doctoral training. Findings: The results show that the proportion of leading marketing publications by authors affiliated to British universities have held steady at about 2 per cent, while the productivity of several other countries has accelerated past Britain. However, to retain that share, Britain has increasingly depended upon importing people whose PhD is not British. This contrasts with some other European countries that are now more productive than Britain, but mainly recruit locals with local PhDs. The pattern of decline in the UK is related to the impact of Britain's research assessment exercise and the continuation of relatively weak social science research training. Research limitations/implications: The analysis is limited by only looking at one academic discipline and only the top few academic journals in the field. Practical implications: The findings have implications at several levels. At a national policy level it questions the value of the research assessment exercises that appear to have presided over a decline in research productivity. For institutions, it questions the value in investing in developing local talent when success has come to those who buy talent internationally. Perhaps, the major implication arises from Britain's academic productivity declining while neighbouring countries have grown in international excellence. Originality/value: At a time when the continuation of expensive university research assessments is being questioned the research findings add value to the current debate in showing how that very process has accompanied academic decline. © Emerald Group Publishing Limited.

Aspects of the design and control of manufacturing systems subject to demand uncertainty

The recent explosive growth in advanced manufacturing technology (AMT) and continued development of sophisticated information technologies (IT) is expected to have a profound effect on the way we design and operate manufacturing businesses. Furthermore, the escalating capital requirements associated with these developments have significantly increased the level of risk associated with initial design, ongoing development and operation. This dissertation has examined the integration of two key sub-elements of the Computer Integrated Manufacturing (CIM) system, namely the manufacturing facility and the production control system. This research has concentrated on the interactions between production control (MRP) and an AMT based production facility. The disappointing performance of such systems has been discussed in the context of a number of potential technological and performance incompatibilities between these two elements. It was argued that the design and selection of operating policies for both is the key to successful integration. Furthermore, policy decisions are shown to play an important role in matching the performance of the total system to the demands of the marketplace. It is demonstrated that a holistic approach to policy design must be adopted if successful integration is to be achieved. It is shown that the complexity of the issues resulting from such an approach required the formulation of a structured design methodology. Such a methodology was subsequently developed and discussed. This combined a first principles approach to the behaviour of system elements with the specification of a detailed holistic model for use in the policy design environment. The methodology aimed to make full use of the `low inertia' characteristics of AMT, whilst adopting a JIT configuration of MRP and re-coupling the total system to the market demands. This dissertation discussed the application of the methodology to an industrial case study and the subsequent design of operational policies. Consequently a novel approach to production control resulted. A central feature of which was a move toward reduced manual intervention in the MRP processing and scheduling logic with increased human involvement and motivation in the management of work-flow on the shopfloor. Experimental results indicated that significant performance advantages would result from the adoption of the recommended policy set.

Theoretical perspectives in purchasing and supply chain management:an analysis of the literature

Purpose – This paper attempts to seek answers to four questions. Two of these questions have been borrowed (but adapted) from the work of Defee et al.: RQ1. To what extent is theory used in purchasing and supply chain management (P&SCM) research? RQ2. What are the prevalent theories to be found in P&SCM research? Following on from these questions an additional question is posed: RQ3. Are theory-based papers more highly cited than papers with no theoretical foundation? Finally, drawing on the work of Harland et al., the authors have added a fourth question: RQ4. To what extent does P&SCM meet the tests of coherence, breadth and depth, and quality necessary to make it a scientific discipline? Design/methodology/approach – A systematic literature review was conducted in accordance with the model outlined by Tranfield et al. for three journals within the field of “purchasing and supply chain management”. In total 1,113 articles were reviewed. In addition a citation analysis was completed covering 806 articles in total. Findings – The headline features from the results suggest that nearly a decade-and-a-half on from its development, the field still lacks coherence. There is the absence of theory in much of the work and although theory-based articles achieved on average a higher number of citations than non-theoretical papers, there is no obvious contender as an emergent paradigm for the discipline. Furthermore, it is evident that P&SCM does not meet Fabian's test necessary to make it a scientific discipline and is still some way from being a normal science. Research limitations/implications – This study would have benefited from the analysis of further journals, however the analysis of 1,113 articles from three leading journals in the field of P&SCM was deemed sufficient in scope. In addition, a further significant line of enquiry to follow is the rigour vs relevance debate. Practical implications – This article is of interest to both an academic and practitioner audience as it highlights the use theories in P&SCM. Furthermore, this article raises a number of important questions. Should research in this area draw more heavily on theory and if so which theories are appropriate? Social implications – The broader social implications relate to the discussion of how a scientific discipline develops and builds on the work of Fabian and Amundson. Originality/value – The data set for this study is significant and builds on a number of previous literature reviews. This review is both greater in scope than previous reviews and is broader in its subject focus. In addition, the citation analysis (not previously conducted in any of the reviews) and statistical test highlights that theory-based articles are more highly cited than non-theoretically based papers. This could indicate that researchers are attempting to build on one another's work.

Practically oriented design projects in mechatronics engineering:a case study of design experiences and outcomes

This paper discusses and presents a case study of a practically oriented design project together with a few examples of implemented design projects recently incorporated into an undergraduate system course at the mechatronics engineering department in Ah-Balqa’ Applied University. These projects have had a positive impact on both the department and its graduates. The focus of these projects is the design and implementation of processor-based system. This helps graduate students cross the border between hardware design and software design. Our case study discusses the research methodology adopted for the physical development of the project, the technology used in the project, and the design experiences and outcomes.

Toward understanding inter-organizational knowledge transfer needs in SMEs:insight from a UK investigation

Purpose - External knowledge is generally believed to be of prime importance to small to medium-sized enterprises (SMEs). However, a review of the literature shows that no empirical research has looked at knowledge management issues at the inter-organizational level in SMEs. This paper seeks to report on an empirical investigation with UK SMEs in the service sector to identify their needs and practices regarding inter-organizational knowledge transfer, and thus provide empirical evidence to support the above belief. Design/methodology/approach - A two-tier methodology (i.e. using both questionnaire survey and interview approaches) is deployed to address the main research objectives. A questionnaire survey of SMEs is carried out to investigate their current inter-organizational knowledge transfer situation and managers' perception on various relevant issues. Then 12 face-to-face interviews with SME managers are conducted to further validate key findings drawn from the questionnaire survey. Findings - The empirical evidence collected from the survey and interviews confirms the general belief that external knowledge is of prime importance for SMEs, and demonstrates that SMEs have very strong needs for external knowledge and inter-organizational knowledge transfer. Research limitations/implications - The findings provide very strong underpinning for further theoretical research on inter-organizational knowledge transfer in SMEs. However, this study has certain limitations: its results may not be applicable to other industrial sectors or the same sector in other countries; or to micro or large companies; nor does it involve cross-cultural issues. Originality/value - By adopting a two-tier research methodology, this study provides more reliable understanding and knowledge on SMEs' inter-organizational knowledge transfer needs and practices, and fills the gap that exists in the empirical investigations on the subject. © Emerald Group Publishing Limited.

Methodology choices and the construction of facts:some implications from the sociology of scientific knowledge

This paper has two objectives: first, to provide a brief review of developments in the sociology of scientific knowledge (SSK); second to apply an aspect of SSK theorising which is concerned with the construction of scientific knowledge. The paper offers a review of the streams of thought which can be identified within SSK and then proceeds to illustrate the theoretic constructs introduced in the earlier discussion by analysing a particular contribution to the literature on research methodology in accounting and organisations studies. The paper chosen for analysis is titled “Middle Range Thinking”. The objective of this paper is not to argue that the approach used in this paper is invalid, but to seek to expose the rhetorical nature of the argumentation which is used by the author of the paper.

Accounting information systems as knowledge objects:some effects of objectualization

This paper will outline a research methodology informed by theorists who have contributed to actor network theory (ANT). Research informed from such a perspective recognizes the constitutive role of accounting systems in the achievement of broader social goals. Latour, Knoor Cetina and others argue that the bringing in of non-human actants, through the growth of technology and science, has added immeasurably to the complexity of modern society. The paper ‘sees’ accounting and accounting systems as being constituted by technological ‘black boxes’ and seeks to discuss two questions. One concerns the processes which surround the establishment of ‘facts’, i.e. how ‘black boxes’ are created or accepted (even if temporarily) within society. The second concerns the role of existing ‘black boxes’ within society and organizations. Accounting systems not only promote a particular view of the activities of an organization or a subunit, but in their very implementation and operation ‘mobilize’ other organizational members in a particular direction. The implications of such an interpretation are explored in this paper. Firstly through a discussion of some of the theoretic constructs that have been proposed to frame ANT research. Secondly an attempt is made to relate some of these ideas to aspects of the empirics in a qualitative case study. The case site is in the health sector and involves the implementation of a casemix accounting system. Evidence from the case research is used to exemplify aspects of the theoretical constructs.

Surveying sexualities: Internet research with non-heterosexuals

In this article we describe and evaluate the process of conducting online survey research about the legal recognition of same-sex relationships (key findings from which we have reported elsewhere, see Harding and Peel, 2006). Our aim in so doing is to contribute to the growing generic literature on internet-based research methods (Nosek et al., 2002; Rhodes et al., 2003; Stern, 2003; Strickland et al., 2003; Thomas et al., 2000) to the research methods literature within lesbian, gay, bisexual, trans and queer (LGBTQ) psychologies (Fish, 2000; Morris and Rothblum, 1999; Meezan and Martin, 2003; Mustanski, 2001) and also to extend the germinal literature focusing on internet research with non-heterosexual groups (Elford et al., 2004; Ellis et al., 2003; Ross et al., 2000). We begin by discussing the process of developing the online survey tool, before outlining the experience of the survey ‘going live’ and providing details of who completed the survey. We conclude by exploring some of the positives and pitfalls of this type of research methodology.

The interaction between master production scheduling and detailed capacity requirements planning : closing the loop in manufacturing resource planning (MRPII) systems

The widespread implementation of Manufacturing Resource Planning (MRPII) systems in this country and abroad and the reported dissatisfaction with their use formed the initial basis of this piece of research which concentrates on the fundamental theory and design of the Closed Loop MRPII system itself. The dissertation concentrates on two key aspects namely; how Master Production Scheduling is carried out in differing business environments and how well the `closing of the loop' operates by checking the capcity requirements of the different levels of plans within an organisation. The main hypothesis which is tested is that in U.K. manufacturing industry, resource checks are either not being carried out satisfactorily or they are not being fed back to the appropriate plan in a timely fashion. The research methodology employed involved initial detailed investigations into Master Scheduling and capacity planning in eight diverse manufacturing companies. This was followed by a nationwide survey of users in 349 companies, a survey of all the major suppliers of Production Management software in the U.K. and an analysis of the facilities offered by current software packages. The main conclusion which is drawn is that the hypothesis is proved in the majority of companies in that only just over 50% of companies are attempting Resource and Capacity Planning and only 20% are successfully feeding back CRP information to `close the loop'. Various causative factors are put forward and remedies are suggested.

Computer integrated manufacturing control

Many manufacturing companies have long endured the problems associated with the presence of `islands of automation'. Due to rapid computerisation, `islands' such as Computer-Aided Design (CAD), Computer-Aided Manufacturing (CAM), Flexible Manufacturing Systems (FMS) and Material Requirement Planning (MRP), have emerged, and with a lack of co-ordination, often lead to inefficient performance of the overall system. The main objective of Computer-Integrated Manufacturing (CIM) technology is to form a cohesive network between these islands. Unfortunately, a commonly used approach - the centralised system approach, has imposed major technical constraints and design complication on development strategies. As a consequence, small companies have experienced difficulties in participating in CIM technology. The research described in this thesis has aimed to examine alternative approaches to CIM system design. Through research and experimentation, the cellular system approach, which has existed in the form of manufacturing layouts, has been found to simplify the complexity of an integrated manufacturing system, leading to better control and far higher system flexibility. Based on the cellular principle, some central management functions have also been distributed to smaller cells within the system. This concept is known, specifically, as distributed planning and control. Through the development of an embryo cellular CIM system, the influence of both the cellular principle and the distribution methodology have been evaluated. Based on the evidence obtained, it has been concluded that distributed planning and control methodology can greatly enhance cellular features within an integrated system. Both the cellular system approach and the distributed control concept will therefore make significant contributions to the design of future CIM systems, particularly systems designed with respect to small company requirements.
