Abstract

Considers the role and practices of total quality management in China. After a brief overview, considers the evolution of quality practices and the links to economic reform in China. From the quality literature, develops a measuring instrument to assess the extent and pervasion of quality practices in China. Then applies this instrument to 428 Northern Chinese companies representing different forms of ownership. Finds that the implementation of quality was highly variable. In general, joint venture companies scored highly in quality practices, in contrast, state owned enterprises scored poorly. Privately owned companies also scored well in some aspects of quality implementation. Concludes that the poor quality performance of state owned companies can be attributed to the attitudes and structures created during the period of the command economy.

Abstract

This paper provides an exploration of the concept and content of agile manufacturing (AM). It describes the nature of the content of AM and synthesises the literature to propose a comprehensive definition of purpose and process. Real agile manufacturing (RAM) is viewed as a strategic process; it is about surviving and prospering in the competitive environment of continuous and unpredictable change by reacting quickly and effectively to changing markets. The paper argues that RAM is evolutionary, in that it is developed from existing systems of management and technologies. However, it is also revolutionary because the full application of RAM involves a departure from existing systems. RAM is shown to be based upon four fundamentals. First, each partner must benefit; thus multiple winners (manufacturers, suppliers, customers) is the objective. Second, integration (recourses, methods, technologies, departments or organisations) is the means of achieving RAM. Third, IT is demonstrated to be an essential condition. Finally, core competence is seen to be the key.

Abstract

Purpose

The purpose of this paper is to present a simple and effective method to search the optimal turn-on and turn-off angles on-line for the control of the switched reluctance motor (SRM). The optimal turn-on and turn-off angles are defined as the ones that can meet torque production requirements with minimum copper loss.

Design/methodology/approach

The optimal turn-on and turn-off angles are first defined based on the analysis of the SRM losses and torque production principles. Then the algorithm for optimal angles searching is developed, and the searching parameters are determined through analytical computation. The optimal angles are approached on-line with iterative process. Simulation and experiments are finally performed to verify the proposed method.

Findings

The presented method can meet torque production requirements while copper loss is minimized. The optimal turn-on and turn-off angles are generally approached within five phase cycles for most of the SRM operation modes. Furthermore, the SRM drive system using the presented method exhibits good dynamics during starting and sudden load operations.

Practical implications

The presented method is simple, and implementation of it is easy. It is an eligible candidate for industrial applications where energy conversion efficiency is crucial.

Originality/value

The optimal turn-off angle definition that considers both torque production and copper loss minimization is proposed. The turn-on and turn-off angles are searched independently on-line with little SRM geometrical information. The searching steps are derived through analytical computation and qualitative analysis so that both the searching speed and algorithm convergence are balanced.

Abstract

Purpose

The purpose of this research is to ascertain the feasibility of fabricating polymer optical fibers (POFs) based textile structures by knitting with Polymethylmethacrylate (PMMA) based optical fibers for textile sensor application. It has long been established that by using the principles of physics, POFs have the capability to function as sensors, detecting strain, temperature and other variables. However, POF applications such as strain and pressure sensing using knitting techniques has since not been very successful due to a number of reasons. Commercially available PMMA-based optical fibers tend to be fragile and susceptible to breakages when subjected to stress during the knitting processes. Also light transmitted within these fibers is prone to leakage due to the curvature that results when optical fibers are interlaced or interlooped within fabric structures.

Design/methodology/approach

Using Stoll’s multi-gauge CMS 350 HP knitting machine, five fabric structures namely, 1 × 4 float knit structure, tunnel inlay knit structure, 3:1 fleece fabric and 2:1 fleece fabric structure respectively were used to knit sensor samples. The samples were subsequently tested for length of illumination and sensitivity relative to applied pressure.

Findings

The results of this preliminary study establish that embedding plastic optical fibers into a knitted structure during the fabric formation process for soft strain sensor application possible. The best illumination performance was recorded for tunnel inlay structure which had an average of 94 cm course length of POF being illuminated. Sensor sensitivity experiments also establish that the relative spectral intensity of the fiber is sensitive to both light and pressure. Problems encountered and recommendations for further research have also been discussed and proffered.

Research limitations/implications

Due to resource limitations, an innovative technique (use of precision weight set) was used to apply pressure to the sensors. Consequently, information regarding the extent of corresponding sensor deformation has not been used in this initial analysis.

Practical implications

Because the fundamental step toward finding a solution to any engineering problem is the acquisition of reliable data, and considering the fact that most of the popular technologies used for soft textile sensors are still bedeviled with the problem of signal instability and noise, the success of this application thus has the tendency to promote the wide spread adoption of POF sensors for smart apparel applications.

Originality/value

As far as research on soft strain sensors is concerned, to the best of the authors’ knowledge, this is the first study to have attempted to knit deformable sensors using commercially available POFs.

Abstract

Purpose

The purpose of the study is to investigate and reveal this relationship of various engineering demand parameters (EDPs) of this structural type and intensity measures (IMs) under intra-plate earthquakes.

Design/methodology/approach

The nonlinear finite element model used was calibrated first to the existing results of the shaking table test to verify the modeling technique.

Findings

This paper investigated the relationship between intensity measures and various engineering demand parameters of cable-stayed bridges using intra-plate earthquakes. The correlation analysis and Pearson coefficient are used to study the correlation between EDPs and IMs. The results showed that peak ground velocity (PGV)/peak ground acceleration, peak ground displacement and root-mean-square of displacement showed weak correlation with IMs. PGV, sustained maximum velocity, a peak value of spectral velocity, A95 parameter, Housner intensity and spectral acceleration at the fundamental period, the spectral velocity at the fundamental period and spectral displacement at the fundamental period were determined to be better predictors for various EDPs.

Originality/value

This paper investigated the correlation between the intensity measures of intra-plate earthquakes with the seismic responses of a typical long-span cable-stayed bridge in China. The nonlinear finite element model used was calibrated to the existing results of the shaking table test to verify the modeling technique. In total, 104 selected ground motions were applied to the calibrated model, and the responses of various components of the bridge were obtained. This study proposed PGV as the optimal IM.

Abstract

Today humanity is facing a time period, in which the speed and rate of change in different fields are faced. The rapid and effective change in the technological, economic, military, social and cultural fields all over the world in recent years has had important results in many topics such as informatics, interactive communication, production, data production and sharing and forms of consumption and perception. Changes and developments at very high speeds and rates affect the personal life, social life and work life in a deep manner, especially after the 1980s, paving the way for many concepts such as globalization, Industry 4.0, digitalization, new economy, new world order and digital transformation age to be the leading variables in every field of social sciences.

Production, consumption and communication forms at the global level are becoming more and more in depth and predicting the future is becoming more and more difficult and valuable. Understanding, analyzing and predicting the future for national and international companies and organizations directly and indirectly affect all economic, military and political variables. At this point, competition stands out as one of the most critical concepts for survival and growth for profit-oriented companies.

Based on this, the topics and contents selected in this study were created to cover the field of management and strategy. Indeed, in this study, the concept of organizational agility is explored theoretically from a historical perspective on the concept of Industry 4.0 and especially emphasized the dimensions and components of agility used in today’s world.

Within the scope of this study, the aim is to define and present the general framework of the Industry 4.0 and agile firms, which aim to combine the conceptual and theoretical infrastructure with the implementation of the agile firms within the field. In this respect, the study defines the situation coming from the past together with the world of today in the relationship of the technological and economical dimensions of globalization with the digitalization and latest theoretical view for the agile firm’s structure and management. On the other hand; in this study, the possible effects of the recent COVID-19 pandemic crisis on the management of organizations are interpreted in the context of Industry 4.0 and agile companies. This aim will provide a foresight for the future periods, with the conclusions added with the theory of senism, which present the dominant value of the study.

Abstract

Purpose

The purpose of this paper is to identify the mediating effect of lean management (LM) dimensions on the relationship between flexible manufacturing systems (FMS) dimensions and operational performance metrics.

Design/methodology/approach

A survey questionnaire was developed based on previous literature and interviews conducted at the automotive facilities visited that identified 28 lean dimensions, 15 flexibility dimensions and 8 operational performance metrics. The survey was presented to 175 North American automotive manufacturing managers through interviews conducted at 64 automotive facilities. A total of 164 usable responses were studied.

Findings

Lean and FMS are multi-dimensional philosophies, the results demonstrate that the automotive industry in North America has implemented many dimensions of both philosophies. Each dimension is categorized based on specific organizational metrics. The 64 facilities studied use common dimensions identified by this study for lean and flexibility. Data analysis indicates a direct link between lean, flexibility and operational metrics. It shows that LM plays a critical role in improving the impact of flexibility on performance metrics. The results also indicate that specific lean and FMS dimensions or categories have higher significant roles than others in the relationship between LM, FMS and operational performance metrics.

Research limitations/implications

Since the sample size only considered automotive manufacturing facilities, the results need to be considered with caution.

Originality/value

This research empirically develops a framework linking FMS and LM to operational performance metrics. This research addresses an area within which there is little consensus on the relationship between LM, FMS and their impact on operational performance metrics. The study is unique due to the depth and breadth of the investigation that far exceeds previous literature conducted. In addition, this research highlights the LM and FMS practices on which managers should focus on when attempting to improve operational performance metrics at their facility.

Abstract

Purpose

This paper aims to propose a model to assess leagile strategy effectively as one of the most discussed production and supply chain strategies.

Design/methodology/approach

This research is based on an integrated FLinPreRa-FQFD approach, which ranks and determines the importance of criteria and indices of the proposed model in an effective way.

Findings

“Cost” has been taken as the most important competitive advantage in the four selected industries. “Customer and market sensitiveness” has been considered as the most important enabler in three industries (“machinery and equipment,” “textile” and “food and beverage”). “Collaborative relationship” has been also considered as the most important enabler in the “material and chemical products” industry to gain leagility.

Practical implication

On the one hand, the proposed research model can be used as a reference guide for firms to reach leagility. This model presents indices of leagility at different levels. On the other hand, with respect to the main activities of the Iran Chambers of Commerce, Industries, Mines and Agriculture, including Qazvin’s, committed to provide requirements for economic development, this work provides an opportunity for the implementation of leagility model in 151 active companies. It also gives new insights into the leagility application in the four industries and Qazvin’s Chamber of Commerce, Industries, Mines and Agriculture.

Originality/value

This research has two main contributions. First, it presents a model of enablers and attributes of leagility, combined with four competitive advantages. Second, the research study is equipped with an integrated and consistent methodology that, first, helps decision makers prioritize their goals and agenda by means of fewer paired comparisons without the need of consistency rate and, second, allows for direct evaluation of impact of enablers on attributes of leagility.

Abstract

Purpose

Agile methods have proven successful in increasing customer satisfaction and decreasing time and cost to market under uncertain conditions. Key characteristics of agile methods are lean, flexibility and highly iterative development with a strong emphasis on stakeholder involvement. Today construction firms in general and small to medium‐sized enterprises (SMEs) in particular are surviving in a drastic competitive environment in which they are facing more and more challenges. Additional innovation is needed in the construction sector, with increased participation from more competitive SMEs. The main purpose of this paper is to present a model to prioritize available management systems to help SMEs address the challenge of today's market competition more effectively.

Design/methodology/approach

The research methodology used is that of interpretative case study and grounded theory based on a strong empirical foundation, on which new theoretical insight into knowledge management as an autonomous action is developed. The paper looks at ways by which SMEs are managed, based on the empirical data collected from 12 case studies. It presents the empirical findings drawn from the case studies. Finally, the adoption of agile methods is subjectively assessed as to its potential contribution for improving the business processes of small and medium construction firms.

Findings

It is assessed that agile methods offers considerable potential for application in construction SMEs and that there are significant hurdles to its adoption in the actual phase. Should these be overcome, agile methods offers benefits well beyond any individual company.

Practical implications

Construction firms need to be aware of the advantages of new management paradigms and practices. The analysis shows that SMEs in the construction sector have to internalize agile values into their business processes to reap the benefits of agile methods. It also reveals that existing practices show some kind of agile flavours.

Originality/value

Agile principles and methods are explored, including: philosophy, values, practices and benefits. The management approaches used by construction SMEs are analyzed and discussed. The paper presents recommendations and insights for enhancing the performance and efficiency of SMEs by adopting agile values in their business processes.
