Abstract

Purpose

To design a quality improvement oriented training and education programme (Q_TEPS) for a company manufacturing milk products and to explore its performance using a financial accounting system.

Design/methodology/approach

A company manufacturing milk products was visited and the processes were studied. The literature on Q_TEPS was referred to design Q_TEPS unique to the milk product manufacturing company. The feasibility of implementing Q_TEPS in the company was checked by interviewing the executives. A financial accounting system was used to evolve the income and expenditure account and the balance sheet pertaining to Q_TEPS in the company. The feedback collected using questionnaires was used to establish the validity of Q_TEPS and their financial accounting system in the company.

Findings

The implementation of Q_TEPS in the milk manufacturing company would enable the company to reap a considerable number of tangible and intangible benefits.

Research limitations/implications

It being a government run company, test implementing Q_TEPS was not possible. The income and expenditure account and balance sheet were developed by projecting the performance of Q_TEPS in the company. However, this exercise was done with the consultation of the executives in the company and hence the values projected in the above statements may not deviate considerably from the real time performance of Q_TEPS.

Practical implications

The feedback on Q_TEPS and their financial accounting system led to an impression that they can be implemented in practice. However, in order to enable this, the business procedures must be made simple, flexible and friendly to experiment such research programmes in the future.

Originality/value

The literature review indicates that no work has been done on implementing Q_TEPS in a milk product producing company. Also, it is discernable that the performance of Q_TEPS has not been viewed using financial values. The contribution of this paper would lead to the attainment of these research and practical imperatives.

Abstract

Purpose

This article seeks to propose a technique called total quality function deployment (TQFD) and to appraises its practicality by applying it to a traditional pump‐manufacturing environment.

Design/methodology/approach

The deficiencies of QFD techniques were studied. The theory of the TQFD technique was developed with the objective of overcoming these deficiencies. Two pump‐manufacturing companies were involved, while examining the practicality of TQFD technique.

Findings

A traditional pump‐manufacturing environment lacks knowledge of implanting techniques like QFD, which challenges the researchers to test‐implement, the techniques like TQFD. Yet the successful development of TQFD documents during the reported research project indicates the practical feasibility of TQFD implementation in pump‐manufacturing companies.

Research limitations/implications

The practicality of TQFD was tested by involving two pump‐manufacturing companies located in the city of Coimbatore in India. These two companies may not represent the global pump‐manufacturing environment. However, the pump‐manufacturing trend is uniformly showing sluggish growth at global level. Hence, the inferences drawn may considerably represent traditional pump‐manufacturing environment at the global level.

Practical implications

Since TQFD documents are successfully developed, engineers can be trained to become TQFD coordinators. These engineers will transfer the voice of customers into the practical field by following the implementation procedure presented in the paper.

Originality/value

So far no researchers have reported the theory and practice of TQFD. Pump manufacturing companies lose their market share because of the failure to translate customers' vague languages into technical languages through the involvement of all personnel and holistic exploitation of resources of the organisation. TQFD is a very valuable technique to meet this imperative.

Abstract

Purpose

The principal aim of this study was to provide more realistic output data based on imprecise measurements of product quality. The real‐world problems in fuzzy testing and selecting better processes performance are considered.

Design/methodology/approach

The Taguchi index, which provides numerical measures on process performance, has been widely used in the industry. In practice, the Taghchi index is estimated by sample data, thus it is of interest to obtain the confidence limits of the estimate Cpm for assessing processes. In addition, it is much more realistic, because in general the output quality characteristics of continuous quantities are more or less imprecise. Using the approach taken by Buckley, with some extensions, a general method is used to combine the vector of fuzzy numbers to produce the membership function of a fuzzy estimator of Cpm for further fuzzy testing and selection of better process performances.

Findings

As the rapid advancement of manufacturing technology occurs, current firms are increasing their levels of out sourcing and are relying more heavily on their supply chain as a source of their competitive advantage. Supplier selection decisions have become an important component of production and logistics management. Those decisions have a significant impact on manufacturers' ability to compete as purchases from outside suppliers may account for a large proportion of a product's costs.

Research limitations/implications

The authors assume that measurements are taken from normally distributed populations in this research. Using fuzzy inference to assess manufacturing process capability processed using imprecise data under mild and severe departures from normality would be an interesting issue for further research.

Practical implications

From a managerial standpoint, considering stochastic uncertainty and fuzziness of data during testing and selecting the better supplier often provides a strong incentive to suppliers to adhere to the conscious gathering of data and variance reductions, as well as to quality requirements and standards.

Originality/value

An obvious advantage of process capability analysis over traditional classical approaches, which use binomial distribution for estimating low fractions of NC, is that reviewing a smaller sample reduces time, effort, and expenses.

Abstract

Purpose

The purpose of this paper is to explore the feasibility of adopting a pilot project approach for foreseeing the working and financial viability of a technique, named as agile innovative total quality function deployment (agile ITQFD).

Design/methodology/approach

The agile ITQFD technique and its financial accounting system were designed. The implementation study of two pilot projects on agile ITQFD was conducted in an electronics switches manufacturing company. The statements of the financial accounting system were used to foresee the financial viability of agile ITQFD projects.

Findings

The research reported in this paper indicates the feasibility of adopting a pilot project approach and its financial accounting system for test implementing new techniques and models in the organisations aspiring to attain global competitiveness.

Research limitations/implications

Like many other modern organisations, the company in which the research work was carried out has been aspiring to compete globally. Hence, even though the implementation study involved only two pilot projects, the implications of this research would represent the global scenario as well.

Practical implications

Currently practitioners struggle to choose the best techniques for applying them in specific cases. The research reported in this paper would help practitioners in this regard to adopt the pilot project approach and its financial accounting system.

Originality/value

The pilot project approach reported in this paper helps a company save time and money while exploring the practical compatibility of the technique. The financial accounting system presented would be useful in foreseeing the viability of projects using monetary values.

Abstract

Purpose

The purpose of this paper is to describe and implements an analytic hierarchy process (AHP)-QFD model for selecting the best location from an organization point of view which picks the site with the best opportunity requirements. Integration of AHP-QFD process gives us a new approach to assist organizations through observing various factors and selecting the best location among different alternatives. This approach uses AHP method to match the preferences required by decision makers and these preferences are applied to the characteristics of QFD. The model fundamental requirement are perfect potential locales and the areas are contrasted and both quantitative and qualitative elements to permit directors to join managerial experience and judgment in the answer process. The AHP-QFD model is also applied on a case study to illustrate the solution process.

Design/methodology/approach

The integration of AHP and QFD is used to analyze available options and select the best alternative. This can be done by ranking each criterion through a pairwise comparison. Given collected data, the QFD approach is used to find the capability of each criterion.

Findings

Integration of AHP-QFD is used to select the best alternative in facility location. This integrated approach can be best used in dealing with facility location problems.

Originality/value

The developed AHP-QFD model in facility location problems, facilitates the inclusion of market criteria and decision maker opinion into the traditional cost function, which has been mainly distance base in the literature.

Abstract

Purpose

Quality function deployment (QFD) has been used to translate customer requirements into engineering characteristics of a product, while benchmarking was developed to search for the best industry practices, which will lead to exceptional performance through the implementation of these best practices. However, no attempt has been made to integrate QFD with benchmarking to identify the best practices of QFD model. This paper aims to classify the QFD models and thereby applying benchmarking process to propose the best practices of QFD model.

Design/methodology/approach

The fundamental benchmarking model developed by Camp has been used to benchmark the existing QFD models available in the literature.

Findings

Benchmarking the QFD models revealed about 36 QFD steps in the first phase of the house of quality. The tools used in solving for each practice are also reported.

Research limitations/implications

The proposed model is conceptual and it requires validation by implementing the same in an organization to understand its effectiveness.

Originality/value

Utilizing the benchmarking process to develop the best practices of QFD model is an original concept.

Abstract

Purpose

Most of the total quality management (TQM) programmes implemented in the printing industry fail to produce the intended benefit, because of the view that quality achievement is workers responsibility. The purpose of this paper is to examine the role management plays in the implementation of TQM programme in the Ghanaian printing firms.

Design/methodology/approach

The study employed mixed method in gathering relevant data. A cross-sectional survey questionnaire was given to 145 managers of registered members of Ghana Printers and Paper Converters Association, Southern Sector to assess the role management plays in TQM programme. Key informant interview was conducted among ten randomly selected production managers of printing firms to complement the survey data.

Findings

The study finds out that organizational performance (OP) is not significantly influenced by the level of commitment of top management in a printing organization. Rather OP is greatly influenced and determined by leadership styles of management and the quality policy which guides printing operations.

Practical implications

The Ghanaian printing industry can ensure better OP by considering the kind of leadership style exhibited in the firm and develop quality policy to guides printing operations and activities. No matter the level of commitment of organizational resources, if it is not back by a good leadership style and a quality policy, TQM initiative will not yield the intended result.

Originality/value

The study presents managerial issues and practices critical for successful TQM programme in the Ghanaian printing industry.

Abstract

Purpose

The purpose of this paper is to initiate researches in the direction of integrating knowledge management (KM) principles with ISO 9001:2008 Supported Quality System and motivate the practitioners to implement such integrated system in real-time practice.

Design/methodology/approach

The principles of KM were integrated with the five major clauses of ISO 9001:2000 standard. After designing this integrated system, it was subjected to peripheral implementation study in a government-managed company situated in India. The knowledge portal required for maintaining this integrated system was also developed.

Findings

ISO 9001:2008 and ISO 9001:2000 standards rest on the same process-based quality system model which is comprised of five major clauses. Hence, the integrated system proposed in this paper can be utilized by the contemporary organizations to infuse KM principles in ISO 9001:2008 based quality system.

Research limitations/implications

Though the integrated system designed in this research could not be implemented in a full-fledged manner, the experiences gained have been useful to indicate the future direction of research and practice for integrating KM principles with ISO 9001:2008 Supported Quality System.

Practical implications

A roadmap has been evolved to guide the practitioners to implement Knowledge Managed ISO 9001:2008 Supported Quality System.

Originality value

No researcher or practitioner has so far contributed a model integrating the process-based quality system incorporated in ISO 9001:2000 and ISO 9001:2008 standards with KM principles. As this gap is filled in this paper, the contributions of this paper are valuable to both researchers and practitioners.

Abstract

Purpose

The purpose of this study is to explore the effects of aerospike and hemispherical aerodisks on flow characteristics and drag reduction in supersonic flow over a blunt body. Specifically, the study aims to analyze the impact of varying the length of the cylindrical rod in the aerospike (ranging from 0.5 to 2.0 times the diameter of the blunt body) and the diameter of the hemispherical disk (ranging from 0.25 to 0.75 times the blunt body diameter). CFD simulations were conducted at a supersonic Mach number of 2 and a Reynolds number of 2.79 × 106.

Design/methodology/approach

ICEM CFD and ANSYS CFX solver were used to generate the three-dimensional flow along with its structures. The flow structure and drag coefficient were computed using Reynolds-averaged Navier–Stokes equation model. The drag reduction mechanism was also explained using the idea of dividing streamline and density contour. The performance of the aero spike length and the effect of aero disk size on the drag are investigated.

Findings

The separating shock is located in front of the blunt body, forming an effective conical shape that reduces the pressure drag acting on the blunt body. It was observed that extending the length of the spike beyond a specific critical point did not impact the flow field characteristics and had no further influence on the enhanced performance. The optimal combination of disk and spike length was determined, resulting in a substantial reduction in drag through the introduction of the aerospike and disk.

Research limitations/implications

To predict the accurate results of drag and to reduce the simulation time, a hexa grid with finer mesh structure was adopted in the simulation.

Practical implications

The blunt nose structures are primarily employed in the design of rockets, missiles, and re-entry capsules to withstand higher aerodynamic loads and aerodynamic heating.

Originality/value

For the optimized size of the aero spike, aero disk is also optimized to use the benefits of both.
