Abstract

Purpose

Multiple classifier systems have been used widely in computing, communications, and informatics. Combining multiple classifier systems (MCS) has been shown to outperform a single classifier system. It has been demonstrated that improvement in ensemble performance depends on either the diversity among or the performance of individual systems. A variety of diversity measures and ensemble methods have been proposed and studied. However, it remains a challenging problem to estimate the ensemble performance in terms of the performance of and the diversity among individual systems. The purpose of this paper is to study the general problem of estimating ensemble performance for various combination methods using the concept of a performance distribution pattern (PDP).

Design/methodology/approach

In particular, the paper establishes upper and lower bounds for majority voting ensemble performance with disagreement diversity measure Dis, weighted majority voting performance in terms of weighted average performance and weighted disagreement diversity, and plurality voting ensemble performance with entropy diversity measure D.

Findings

Bounds for these three cases are shown to be tight using the PDP for the input set.

Originality/value

As a consequence of the authors' previous results on diversity equivalence, the results of majority voting ensemble performance can be extended to several other diversity measures. Moreover, the paper showed in the case of majority voting ensemble performance that when the average of individual systems performance P is big enough, the ensemble performance Pm resulting from a maximum (information‐theoretic) entropy PDP is an increasing function with respect to the disagreement diversity Dis. Eight experiments using data sets from various application domains are conducted to demonstrate the complexity, richness, and diverseness of the problem in estimating the ensemble performance.

Abstract

Purpose

Under such circumstances, how to assign the highest priority for future products which will create the greatest value will be the key success factor for a product planning model. The purpose of this study is to construct an improved planning model for new products based on the theoretical structures of technology roadmaps and patent analysis.

Design/methodology/approach

This study takes the perspective of a product planning strategy, using technology roadmap developed by Institute of Manufacturing Technology of the University of Cambridge, combining with scenario planning and patent analysis. The main body of the proposed model is the technology roadmap of the product. Through patent analysis, the technology roadmap was integrated into the hierarchical execution of product planning to improve the disadvantages of the original technology roadmap and thereby clarify the content of the implemented procedure. With the planning of digital home products in a large household appliance manufacturer in China as a case study, the feasibility of the proposed model was verified.

Findings

The improved planning model for new products comprised five planning phases: market scenario planning, product feature analysis, technological development analysis, patent combination analysis, and resource allocation. A matrix corresponding to product planning was established. The case study is to find out the developing trends in next‐generation product features in six different scenarios of digital home for M, a home appliance manufacturer. There are five steps of the product planning model. The product planning model provides enterprises with integrated information from market demand, technology as well as patents. At the same time, it is easy to maintain and reproduce. The authors expect the model to make a contribution to practical product planning.

Originality/value

This model should become an essential prediction tool for enterprises developing new products and can assist in decision‐making and strategic implementation.

The purpose of this paper is to analyze the development of body fitness equipment in Taiwan from the viewpoint of innovation and the factor of success for innovation.

Abstract

Purpose

The purpose of this paper is to analyze the development of body fitness equipment in Taiwan from the viewpoint of innovation and the factor of success for innovation.

Design/methodology/approach

The research methods include a literature study and a case study. In addition, the innovation activity of an enterprise is based on the viewpoint of procedure (input‐process‐output). The innovation activity of an enterprise is separated into three phases: innovation motivation, innovation process, and innovation performance.

Findings

The enterprise's competitive advantage and efficiency can clearly be seen, and the reason for the enterprise's success can easily be identified through a structural analysis of the innovation process. The research results indicate four factors for the success of Johnson: mastering technology, good management, employment of diversified talents, and clear brand positioning.

Research limitations/implications

The innovation research model provides a comprehensive summary of the innovation process, stressing innovation activity. The study of the factors of success does not establish quantified or non‐quantified innovation indicators.

Practical implications

The factor of success of innovation is not exactly the same for every company. Sorting and analyzing the individual cases can serve as a basis of reference and act as a guidepost for other companies in similar industries during their business development.

Originality/value

The analysis model of innovation activity can clearly explore the development process of the innovation success of an enterprise. Simultaneously, this research can serve as a role model for other companies when they innovate.

Abstract

Purpose

The purpose of this paper is to find the key innovative principles for evaluating the long-term care (LTC) cloud system by exploring contradictory and complex points in its development.

Design/methodology/approach

The theory of inventive problem solving (TRIZ) and the decision-making trial and evaluation laboratory (DEMATEL) approaches are integrated to resolve complex contradictions in the system. The heuristic reasoning of TRIZ is applied to obtain innovation principles for an LTC cloud mining system. However, the importance and feasibility of these innovative principles require further assessment. In this study, DEMATEL is employed to clarify the complex relationships among the principles and evaluate their key influences.

Findings

This paper identifies six primary contradictions and derives 25 innovative principles for the resolution of these conflicts. Further analysis confirms three key innovative principles. First, the government should consider the overall planning of the cloud system platform, followed by the participation of other medical and LTC institutions. Second, the information capability of LTC institutions should be unified by recording the pathology data of care recipients to create an information exchange system. Third, LTC institutions should act in cooperation with medical institutions to provide professional medical capabilities.

Originality/value

The contributions of this paper are two-fold. First, this study provides an integrated methodology integrating the TRIZ and DEMATEL approaches to resolve LTC problems. Second, this research identifies the key innovative principles for developing an LTC cloud system in Taiwan.

This paper focuses on the relationship between spontaneous business groups, such as the Taiwanese Businessmen Association (TBA), and the Chinese government.

Abstract

Purpose

This paper focuses on the relationship between spontaneous business groups, such as the Taiwanese Businessmen Association (TBA), and the Chinese government.

Design/methodology/approach

In analysing the relationship between the TBAs and the Chinese government, this paper focuses on three cities, Tianjin, Kunshan and Dongguan. Furthermore it observes Taiwanese investment in mainland China from 1987 to 2004, in three sub‐periods: 1987‐1993, 1994‐1999, 2000‐2004. Statism (e.g. rational choice) appears to be a valid theoretical framework.

Findings

It was found that the Chinese government's changing interaction with Taiwanese businesses always suited their best interests at the time, which proves that the Chinese government applied rational module in interacting with Taiwanese businesses.

Research limitations/implications

Rational choice is not a comprehensive approach in political science, but it is the most suitable approach to analyse the interaction between the Chinese government and Taiwanese businesses.

Practical implications

The first TBA was established in Beijing in 1990; nowadays there are over 100 TBAs in mainland China. It has been argued that TBAs can be seen as the emergence of a sort of civil society in mainland China; to others, they merely reflect the strong will of the Chinese government to attract foreign investment.

Originality/value

This paper demonstrates that Taiwanese businesses is a security asset for the Chinese government in the cross‐Strait relationship.

Abstract

Purpose

This research aims to better understand customer experience, as it relates to customer commitment and provides a framework for future research into the intersection of these emerging streams of research.

Design/methodology/approach

This research contributes to theoretical and practical perspectives on customer experience and its measurement by integrating extant literature with customer commitment and customer satisfaction literature.

Findings

The breadth of the domains that encompass customer experience – cognitive, emotional, physical, sensorial and social – makes simplistic metrics impossible for gauging the entirety of customers’ experiences. These findings provide strong support of the need for new research into customer experience and customer commitment.

Practical implications

Given the complexity of customer experience, managers are unlikely to track and manage all relevant elements of the concept. This research provides a framework identifying empirically the most salient attributes of customer experience with particular emphasis on those elements that enhance commitment. This offers insight into service design to correspond with specific commitment and experience dimensions.

Originality/value

This research is the first to examine the customer experience as it relates to customer commitment – a key factor in customer loyalty, positive word of mouth and other desired outcomes for managers and marketers. This paper provides a framework for future research into these emerging topics.

Abstract

Purpose

The purpose of this paper is to identify the impact of career plateau (hierarchical and job-content plateau) on internal employability, and to investigate psychological contract breach as a moderator on the relationship between career plateau (hierarchical and job-content plateau) and internal employability.

Design/methodology/approach

Data were collected by distributing paper-based questionnaires to 521 workers in private banking sectors in Taiwan. Hierarchical regression analysis was used to examine the results of the relationships.

Findings

The results supported the idea that career plateau (hierarchical and job-content plateaus) could be a significant antecedent of internal employability. Psychological contract breach significantly moderated the negative relationship between career plateau (hierarchical and job-content plateau) and internal employability. Specifically, the negative relationship between career plateau and internal employability will be stronger for employees who perceive a higher level of psychological contract breach.

Practical implications

These findings can help human resource practitioners gain a better understanding of the value of applicable approaches as an influence on a plateaued employee’s perception of internal employability, and to facilitate a positive employer–employee relationship, which could foster both a successful career for an individual and a prosperous performance for the organization that employs them.

Originality/value

Career plateau have been aroused variety issues in HR practice, but employability and psychological contract breach have barely been discussed with career plateau. This study empirically establishes the correlation between career plateau and internal employability as well as shown that psychological contract breach would decrease the plateaued individual’s willingness to stay in the current organization. Thus, the career plateau may provide organizations with a helpful perspective on one’s career development. Building substantial relationships between employees and employers lead to better human capital for organizations as it deals with rapidly changes in the real world.

This paper aims to design an automatic inspection system for the characters on tire molds, which involves a vision-based inspection method for the characters on tire molds.

Abstract

Purpose

This paper aims to design an automatic inspection system for the characters on tire molds, which involves a vision-based inspection method for the characters on tire molds.

Design/methodology/approach

An automatic inspection equipment is designed according to the features of the tire mold. To implement the inspection task, the corresponding image processing methods are designed, including image preprocessing, image mosaic, image locating and character inspection. Image preprocessing mainly contains fitting the contours of the acquired tire mold images and those of the computer aided design (CAD) as the arcs of two circles and polar transformation of the acquired images and the CAD. Then, the authors propose a novel framework to locate the acquired images into the corresponding mosaicked tire mold image. Finally, a character inspection scheme is proposed by combining an support-vector-machine-based character recognition method and a string matching approach. At the stages of image locating and character inspection, image mosaic is simultaneously used to label the defects in the mosaicked tire mold image, which is based on histograms-of-gradients features.

Findings

The experimental results indicate that the designed automatic inspection system can inspect the characters on the tire mold with a high accuracy at a reasonable time consumption.

Practical implications

The designed automatic inspection system can detect the carving faults for the characters on the tire molds, which are the cases that the characters are wrongly added, deleted or modified on the tire mold.

Originality/value

To the best of the authors’ knowledge, this is the first automatic vision-based inspection system for the characters on tire molds. An inspection equipment is designed and many novel image processing methods are proposed to implement the inspection task. The designed system can be widely applied in the industry.
