Abstract
Purpose
The purpose of this paper is to re‐examine the solution methodology to the facility grouping problem in group technology originally outlined by Mukhopadhyay et al. The aim of this re‐examination is to attempt to resolve some of the problems associated with the original solution methodology and to provide the system designer with an improved technique for the creation of an efficient initial system design solution. Cellular manufacture by its very nature requires work‐part transfer both within a machine cell and in some instances between machine cells. By utilising a design methodology which seeks to minimise work‐part transfer, these non‐value but cost adding tasks are kept to a minimum, thereby providing a faster throughput time and lower operational costs for companies who use cellular manufacturing systems in their production operations.
Design/methodology/approach
In approach, the technique advocated parallels the possible alternative solution method suggested by John et al. to resolve the problem of edge ranking ties which exists in the original Mukhopadhyay et al. solution technique. Presented and discussed in this contribution is a revised flow direction weighting scheme (FDWS) which simplifies the solution input data requirements and overcomes a perceived disadvantage in the earlier scheme outlined by John et al. The methodology outlined in the paper is subsequently evaluated for its generic nature, applicability and effectiveness via the use of previously published synthetic production data, and the findings compared to the results determined by several alternative approaches to the problem.
Findings
The development and application of the FDWS to cellular manufacturing system design is outlined in the paper and the usefulness of the technique is subsequently examined and compared to the results found for several competing methods. The approach provides for the identification of improved solutions to the test problems examined in both of the earlier contributions by Mukhopadhyay et al., and John et al. In addition, the results show that irrespective of the assessment criteria used, the FDWS technique provides solutions that are comparable to or better than the alternative approaches examined.
Originality/value
The proposed FDWS technique further contributes to the existing knowledge base on cellular manufacturing system design. It can provide good initial solution guidance for manufacturing system designers and thereby reduce the time required to achieve an acceptable and cost efficient design for a cellular production system.

Abstract
Purpose
Using the weighted similarity coefficient (WSC) technique in the design of manufacturing facilities provides the system designer with a suitable method for the creation of efficient manufacturing cells. The formation of such well designed machine cells will then hopefully ensure that the achievable cost reduction benefits, in terms of lower operational costs incurred via the transfer of components between machines, are obtained by companies that wish to use cellular manufacturing in their approach to production operations. The aim of this paper is to outline and evaluate the application of a particular WSC equation to the formulation and design of cellular manufacturing systems.
Design/methodology/approach
By using a pragmatic approach, the paper chronicles the design and development of a particular weighted similarity coefficient as a means of defining a possibly useful methodology for cell design in manufacturing systems. The technique outlined is subsequently evaluated for its generic nature, applicability and effectiveness via the use of previously published synthetic production data and a comparison with the results of several alternative approaches.
Findings
The development of the proposed weighted similarity coefficient to manufacturing cellular design is outlined in the paper and the appropriateness of the technique is subsequently evaluated in order that the benefits obtainable by its use to a host organisation are highlighted. In addition, the results show how the approach can lead to useful improvements in cellular manufacturing performance if adopted by manufacturing system designers and implemented in their designs.
Practical implications
The design, development and application of the WSC proposed and its use in manufacturing cellular design provides a simple yet highly effective approach to achieving useful improvements in production system performance through improved work‐part transfer efficiency and associated cost savings. The paper offers practising manufacturing managers and engineers a technique whereby manufacturing cell productive efficiency and output can be improved whilst at the same time achieving a reduction in operational costs.
Originality/value
The paper focuses on the proposed WSC technique which contributes to the existing knowledge base on production cell design and may also provide impetus, guidance, support and encouragement for designers to achieve improved output performance and reduced costs in their manufacturing system designs.

Abstract
Purpose
Using the numerical situation analysis (NSA) technique in the development of corporate strategy provides senior managers with a suitable methodology for the creation of alternative strategic options. Subsequently, it may be used to evaluate those options for possible selection and implementation by the company concerned. In addition, the technique provides a graphic temporal point description of an organisation's strategic situation. Consequently, the aim of this paper is to outline the technique of NSA via a hypothetical example and thereby illustrate its use in practice.
Design/methodology/approach
By using a paradigm approach, the paper indicates the correct application of the NSA technique as a means of defining and evaluating alternative strategic options within a manufacturing company. As proposed, the methodology also permits several graphic illustrations of the strategic situation to be drawn, along with a scheme for monitoring the effectiveness of an adopted strategy.
Findings
The evolution of the suggested NSA technique and its application to the formulation of strategic options for a manufacturing company are outlined in the paper. In practice, its application in four differing industries has resulted in some caveats regarding its use, and to some provisional conclusions being drawn in respect of its usefulness to senior management. These are recorded in the concluding section of the paper.
Research limitations/implications
The design, development and application of NSA proposed in this paper together with the experience of its implementation and use, in practice, highlight a potentially useful extension to existing methods of strategy formulation. The methodology offers senior management a technique, whereby alternative strategic options may be defined and evaluated for possible adoption along with diagrammatic illustrations of an organisation's strategic situation. In addition, the approach allows a selected strategy to be monitored over time for effectiveness, thus providing an early warning mechanism in respect of strategic inutility.
Originality/value
The paper contributes to the existing knowledge based on strategy development, evaluation and selection. It also provides a mechanism for monitoring a selected strategy for effectiveness over time and a structured framework for senior management to undertake the strategic planning process. It may when used in practice achieve an improved level of strategic understanding on the part of senior management and thereby stimulate improved corporate performance.

Abstract
Purpose
The purpose of this paper is to identify the qualitative characteristics that can make manufacturing small to medium‐sized enterprises (SMEs) more robust and hence become economically sustainable in this globally competitive environment. The characteristics identified will form the foundations for defining a new manufacturing management perspective to both academics and industrialists.
Design/methodology/approach
Through a comprehensive case study approach the authors initially analyse the developmental cycle of the subject company and then identify the key characteristics which enabled the company to become economically sustainable and survive in the changing environment in which it operates. The paper opens with a brief academic analysis of sustainability literature available, before developing the case study.
Findings
Traditional business improvement strategies, such as Lean and Agility, which many companies initially follow in an attempt to become more robust and economically stable, allow companies to deliver bottom‐line savings in production terms although their effectiveness depends upon the volume and demand profile of their products. Through the case study outlined in this paper however, a combined approach towards the application of Lean is outlined as a primary means of reducing operating costs alongside the simultaneous implementation of product innovation strategies which allows the company to break into new markets as a means to achieving long‐term economic sustainability and making it more robust to market changes. The development of a business within a business is described as an effective mechanism towards achieving business sustainability.
Research limitations/implications
The paper proposes a novel approach to achieving economic sustainability within a business and can be of benefit to the wider industrial and academic community. The development of work around a single company has its obvious limitations and it is crucial that further work, with a range of companies in the area of business sustainability, is key to developing a comprehensive set of sustainability characteristics.
Practical implications
The paper proposes a set of qualitative characteristics for the development of an economically sustainable manufacturing company. The development of a comprehensive case study with a subject company also directs and enables other companies of similar size and style to apply a similar approach and to achieve economic sustainability in an efficient and effective manner, through reducing production costs, minimising company failure and increasing business efficiency and effectiveness.
Originality/value
The development of a set of sustainability characteristics aimed at tackling directly the issues of economic sustainability is proposed and is considered by the authors as one of a kind. The case study approach also provides for a framework towards the implementation of sustainable manufacturing operations within SMEs.

Abstract
Purpose
The purpose of this paper is to investigate the migratory nature of Lean Six Sigma (LSS) implementation and adoption in manufacturing-based SMEs in the UK. The companies were surveyed at two points over a five-year period. These periods were before and after the 2008 recession point. This being done in order to identify the level of LSS adoption as a result of the tougher economic climate that has prevailed since 2008.
Design/methodology/approach
Analysis is carried out on a sample of 96 manufacturing SMEs from a range of manufacturing sectors in the UK. Data were gathered from company CEOs via a triangulated method of questionnaire, direct observation and interviews.
Findings
The paper provides research information into the characterisation, compatibility and innovativeness of SMEs towards LSS implementation and goes on to provide an implementation classification system and characterises the dynamical nature of LSS development in manufacturing SMEs.
Research limitations/implications
The findings analyse the dynamic nature of LSS implementation in SMEs. Further work will include extending the LSS categorisation system to provide a wider category set that further defines the dynamical nature of LSS implementation. Also, more focused studies in to specific manufacturing sectors will yield greater understanding of the effects of LSS on those sectors.
Practical implications
The paper provides practical research information into the characterisation, compatibility and innovativeness of SMEs towards LSS implementation. It will be of use to practitioners seeking to implement or develop LSS further in their organisations.
Originality/value
This study compares at depth the LSS implementation issues within SMEs. It not only analyses the survey data but characterises their attitudes towards implementing LSS and as such this work makes a contribution to this under researched area.

Abstract
Purpose
The purpose of this paper is to outline the application of a Six Sigma (SS) methodology as a means of reducing supply chain risk in aerospace maintenance repair and overhaul (MRO) functions. In this contribution the LSS method is used to estimate the economic impact on the selection of the most appropriate maintenance strategy pertaining to aircraft display units (DUs) as well as providing a reduction in turn round time (TRT) variation of the DUs.
Design/methodology/approach
The paper develops a SS approach which includes the development of the Monte Carlo technique as a mechanism to identify the most cost effective MRO strategy whilst simultaneously reducing variability in TRT servicing of the DUs. This application enabled the authors to obtain further proof of concept and also to apply a number of focused quality improvement techniques to systematically reduce TRT variation.
Findings
An effective development of the SS approach is proposed and the effectiveness of the method is subsequently evaluated highlighting the benefits to the host organisation. The SS methodology demonstrates that it is possible to identify the most cost effective MRO strategy and thus suggests a suitable DU replacement policy which in turn allows engineers to develop the appropriate maintenance schedules for the company.
Practical implications
The design, development and implementation of this SS methodology offers an approach to achieving a more cost effective MRO strategy whilst reducing TRT variability which can lead to greater predictability of operations which in turn enables the company to effectively synchronise supply with demand. The paper offers practicing maintenance managers and engineers a practical example for increasing productive efficiency and output.
Originality/value
This SS strategy contributes to the existing knowledge base on maintenance systems and subsequently disseminates this information in order to provide impetus, guidance and support towards increasing the development companies in an attempt to move the UK manufacturing sector towards world class manufacturing performance.

Abstract
In an address to the East India Association Sir John Woodhead drew upon his experience as chairman of the Famine Inquiry Commission to review in authoritative fashion what Lord Scarborough described from the chair as one of the most important requirements of to‐day, that of increasing the food supplies and improving the diet of the people of India. Of the present population of about 400,000,000, it has been estimated that fully one‐third are under‐nourished, while a still larger proportion are ill‐nourished for lack of a balanced diet. The staple articles of diet are rice, wheat and millet, and even when these are consumed in adequate quantities their deficiencies in proteins, fats, vitamins, and mineral salts must be made good by protective foods. The technological possibilities of increasing food production are very great. It is known that the yield of rice can be increased by anything up to one‐half by manuring and by the use of improved strains; and that potential increases in millet and wheat are of the order of 30 per cent. The Famine Inquiry Commission concluded that self‐sufficiency in cereals was practicable as well as desirable as a policy for the future, and that a large increase in protective and supplementary foods, such as pulses, vegetables, fruit and fish was entirely feasible. Nor is there any mystery as to how the increase is to be achieved. The methods which must be followed, such as the provision of an assured water supply, the utilisation of every source of fertilising material, the cultivation of improved strains of plants and beasts, the protection of husbandry from pests and of the husbandman from ill‐health—all these are familiar in plans for the improvement of the rural economy of India. What is novel, however, is the increasing recognition that only a concerted effort, on a national scale, employing the resources of the people and of the Government in close partnership, can avail to raise the Indian masses from ramshackle medievalism to ordered, progressive modernity. Improvement of diet is among the most important elements in that improvement of the standard of living which is the principal object of all Indian planning to‐day. At present, lack of purchasing power is the root of malnutrition as of many other evils; increased agricultural production and a better diet arc bound up with the process of increasing the national wealth through simultaneous industrial development. Urbanisation and higher living standards may in turn exert their influence upon the growth of population; for Sir John Wood‐head's commission found that among the upper and professional classes the birth‐rate is falling steadily. Throughout the whole population, indeed, the birth‐rate fell from 34 a thousand in 1940 to 26 a thousand in 1943; but this decline may be due to transient causes only. There seemed good grounds for hoping that the future pressure of population need present no immovable obstacle to the success of a really national movement for better livelihood.

Abstract
Purpose
The purpose of this paper is to provide details of a survey conducted into 300 manufacturing SMEs from a range of different industrial sectors. The survey investigates, over a three‐year period, the attitudes towards and benefits obtained by SMEs through the adoption of Advanced Manufacturing Technologies (AMT). Its purpose is to analyse and disseminate these survey data to academics and industrialists.
Design/methodology/approach
The paper uses a research survey of 300 manufacturing SMEs. Analysis of the findings is provided and SME characterisation tables are developed.
Findings
The paper finds that characterisation, compatibility and innovativeness of SMEs towards AMT implementation were found to vary considerably with the SMEs surveyed. From the survey information, the paper develops a classification system based on the capabilities of these companies to implement Advanced Manufacturing Technologies. The paper will then characterise SME attitudes towards the development of AMT. The paper finally proposes a strategic model for the effective introduction and application of AMT in SMEs.
Research limitations/implications
The survey is limited to SMEs and provides a strong body of evidence relating to AMT development with these companies.
Practical implications
The paper proposes a strategic model for the effective introduction and application of AMT in SMEs. The creation of a generic AMT implementation model provides a framework for a wider number of SMEs to introduce AMT into their respective organisations, since it provides for a systematic approach for SMEs to introduce AMT in an efficient and effective manner, thus reducing implementation costs, minimises risk of project failure and improves project management efficiency.
Originality/value
This paper is the first to explore in depth the AMT implementation issues within SMEs from large‐scale survey data. It not only analyses the survey data but also proposes a model for change, which aims to develop a more structured approach to AMT implementation in SMEs. Therefore, this work will make a contribution to this under‐researched area.

Abstract
Purpose
As healthcare continues to become more expensive and complex, considering the voice of the patient in the design and operation of healthcare practices is important. Wound care and rural healthcare scenarios pose additional complexities for providers and patients. This study sought to identify key determinants of patient service quality in wound care.
Design/methodology/approach
Patients at the wound care/ostomy clinic (WOC) in a rural hospital were surveyed using the Kano model. The Kano model enables the categorization of quality attributes based on the attributes' contribution to the subject's overall satisfaction (and dissatisfaction). Chi-square goodness-of-fit testing, multinomial analysis and power analysis were then used to determine the Kano categories for each satisfaction-related attribute.
Findings
The analyses resulted in 14 one-dimensional attributes and 3 indeterminable attributes. For the one-dimensional attributes, customer satisfaction is directly proportional to the level of performance for that attribute. The one-dimensional attributes included providing correct care on the first, provision of necessary supplies for care, appropriately qualified medical staff and confidence in care provided by medical staff, among others. Understanding the attributes important to the patient drive patient-centered care, which improves positive patient outcomes and recovery. These attributes can then be used by healthcare professionals to design patient-centric processes and services. This research provides a framework for incorporating the voice of the patient into healthcare services.
Research limitations/implications
While the research methodology can be used in other healthcare settings, the findings are not generalizable to other wound care clinics. This research was conducted in one small, rural hospital. In addition, the sample size was small due to the size of the wound clinic; therefore, an analysis of the differences between demographics could not be performed.
Practical implications
Considering the perspectives of rural wound care patients is important, as the patients are an under-served population with unique challenges related to patient care. The research findings detail rural patients' expectations during wound care treatments, which enable the clinic to focus on improving patient satisfaction. This research contributes to understanding the factors that are important to patient satisfaction in wound care. Further, the methodology presented can be applied to other healthcare settings.
Originality/value
While studies exist using the Kano model in healthcare and the literature is sparse in rural healthcare, this is the first case study using the Kano model in wound care to understand patient preferences.
