Abstract

Purpose

High-reliability performance and high-hazard are intertwined in High-Reliability Organizations (HROs) operations; these organizations are highly safe, highly hazardous and highly significant for the modern society, not only for the valuable resources they have, but also the indispensable services they provide. This research intend to understand how HROs could produce high quality performance despite their challenging and demanding contexts. The research followed an emic approach to develop an organizational framework that reflects the contribution of the seeming traits of the organizations to the operations safety based on the workers point of views about the safety of workstations.

Design/methodology/approach

This research adopted mixed methods of in-depth interviews and literature review to identify the structural characteristics of high-reliability organizations (HROs) embedded in the organizations studies and developed a theoretical based structural framework for HROs. Furthermore, a systemic literature review was adopted to find the evidence from the organizations literature for the identified characteristics from the interviews from the first stage. The setting for this study is six Chinese power stations, four stations in Hubei province central China and two stations in the southern China Guangdong province.

Findings

The organizational framework is a key determinant to achieve high-reliability performance; however, solely it cannot explain how HROs manage the risks of hazard events and operate safely in high-hazard environments. High-reliability performance is attributed to the interaction between two sets of determinants of safety and hazard. The findings of this research indicate that HROs systems would be described as reliable or hazardous depending on the tightly coupled setting, complexity, bureaucracy involvement and dynamicity within the systems from one hand, and safety orientation, failure intolerance, systemwide processing, the institutional setting and the employment of redundant systems on other hand.

Originality/value

The authors developed an organizational framework of organizing the safety work in HROs. The applied method of interviewing and literature review was not adopted in any other researches.

Abstract

Purpose

The main purpose of this paper is to develop the theoretical links and empirically examine the association between IT and R&D performance, and their study is to answer management's questions: how should IT resources be organized and managed to enhance the process performance?

Design/methodology/approach

The approach is consistent with the process perspective to the question of IT business value, but this approach is extend. A basic premise of this paper is that the knowledge management (KM) capability could be a critical mediator between IT capability and process performance.

Findings

The results indicate that an organization's KM capability is dependent on IT capabilities, and variation in business process performance is explained by KM capability.

Research limitations/implications

On the one hand, control variables were not included in this study. In fact, firm size might influence process performance. On another hand, the empirical analysis was conducted in the context of one specific process in the manufacturing industry; thus, the generalizability of the results may be limited.

Practical implications

The results indicated that IT managers have to clearly understand the strategic thrust of the organization and institute mechanisms to ensure that IT capabilities are channeled toward the areas important to the organization.

Originality/value

This study contributes to the IT literature by introducing KM capability as a critical mediator between IT capabilities and business process performance, this study improves our understanding of the true business value of IT.

Abstract

Purpose

The purpose of this paper is to explore e‐commerce development strategy from the consumer loyalty perspective in a Chinese context and to examine the impact of some key factors that affect e‐commerce development in China. The policy implications are also presented.

Design/methodology/approach

Data were collected by the wide surveying of trained MBAs with different professional backgrounds. Confirmatory factor analysis and reliability analysis were then used to explore whether the “7C” model of consumer loyalty in electronic commerce is acceptable.

Findings

The results show that security and reputation have the most positive impact on consumer loyalty, and playfulness is not significantly related to the potential variable it belongs to. To those enterprises planning to implement e‐business in China, some advice is given; such as increasing the security and reputation of web sites and enhancing communications between buyers and sellers.

Practical implications

The paper gives directions to the e‐commerce enterprises in developing countries about how to improve consumer loyalty and enhance business competence. Online enterprises can build consumer loyalty by improving their web sites and learning about consumers' behaviors to provide customized products and services. The specific policy measures in China are suggested.

Originality/value

While it is known that consumer loyalty is critical to online enterprises' success, little is known about how to build and improve e‐loyalty in the emerging markets. This paper tries to bridge this gap by examining what affects e‐loyalty, to help better understand consumer loyalty in the emerging markets like China.

Abstract

Purpose

The purpose of this paper is to identify the double-edged sword of customer involvement (perceived relationship quality and coordination cost) in new service development in the hotel industry, and to explore when customers should be involved from the service provider’s view.

Design/methodology/approach

A total of 252 valid questionnaires were collected from hotel managers, and ordinary least squares regression analysis was conducted to test the hypotheses.

Findings

Results not only show that customer involvement causes higher coordination cost but also show no direct positive effect on perceived relationship quality. Furthermore, this study finds that service climate reduces the negative effect of customer involvement and enhances its positive effect. By contrast, customer complexity intensifies the negative effect of customer involvement.

Originality/value

This study empirically examines the double-edged sword of customer involvement and tests the boundary conditions associated with hotel back and front office factors (service climate versus customer complexity).

Abstract

Purpose

In recent years, with the increasingly serious urban water environmental pollution, the government has exerted considerable effort to promote the comprehensive improvement of the water environment and conducted numerous urban water environment treatment public–private partnership (PPP) projects (UWETP-PPP). The sustainability assessment of UWETP-PPP has important theoretical and practical significance for the public and private sectors to systematically evaluate the sustainability of projects and promote the sustainable development of projects. Therefore, the purpose of this paper is to advance a method to evaluate the sustainability of UWETP-PPP.

Design/methodology/approach

The paper adopted fuzzy logic method to evaluate the sustainability of UWETP-PPP. First, this paper constructed the sustainability assessment indicator system of UWETP-PPP. Second, this paper determined the appropriate linguistic scale for assessing the performance ratings and importance weights of UWETP-PPP sustainability indicators and collected experts’ evaluations of the project through questionnaires. Then, the linguistic variables were approximated as fuzzy numbers through the concept of fuzzy theory. Finally, the sustainability of the project was determined and the weak sustainability aspects of the project were identified by calculation.

Findings

The feasibility of this method was verified by a specific case. And, the results of the case study showed that the UWETP-PPP in Xuchang City, China, was sustainable, and the indicators of weak sustainability of the project were identified, namely, internal return ratio (IRR), sustainable cash flow, provision of employment opportunities, energy efficiency, comprehensive use of water resources, use of innovation materials, renewal of project facilities, adoption of advanced engineering technology, use of construction waste and waste recycling and reuse. This paper also proposed corresponding suggestions for further improving the sustainability of the UWETP-PPP in Xuchang City, China.

Originality/value

This paper makes two contributions: first, the fuzzy logic method is applied to provide new ideas for a sustainability assessment of UWETP-PPP, and the assessment results facilitate ways to monitor and estimate the degree of sustainability. Second, the identified indicators of weak sustainability provide useful references for the public and private sectors regarding implementing appropriate measures to improve the sustainability level of UWETP-PPP.

Abstract

Learning outcomes

Following are the learning outcomes: to understand how the tools and frameworks of strategic analysis can be applied to understand the evolution of value creation and capture in the FMCG industry; to analyze the core competencies of a company and understand their relevance in this fast-changing industry; to understand how to evaluate the pros and cons of a certain strategy and business model; and to develop strategic recommendations.

Case overview/synopsis

The case series traces the developments in China’s FMCG industry from the early 2010s to 2017, in general, and the efforts of Beijing WinChannel Software Technology Co., Ltd. (WinChannel) and its affiliated company, Huixiadan, in their attempt to apply new digital technologies to transform the traditional trade channel, in particular. The decision point of Case A, in early 2015, is how WinChannel can help improve the reach and efficiency of the traditional trade channel and wonders if the emerging online/mobile B2B FMCG platforms are the right solution for the increasingly digitized FMCG retail industry in China. The decision point of Case B, at the end of 2017, is how could Huixiadan’s business model be sustainable and what it should do to withstand the competitive threats even as it tries to exploit opportunities in the traditional FMCG industry in China.

This paper aims to describe a simple low-pass filter to suppress torque pulsation and current harmonics in permanent magnet synchronous motor (PMSM) drives.

Abstract

Purpose

This paper aims to describe a simple low-pass filter to suppress torque pulsation and current harmonics in permanent magnet synchronous motor (PMSM) drives.

Design/methodology/approach

For the control of the PMSM, a field-oriented control algorithm is always used. The proposed filter is actually a resistance, inductance, capacitance (RLC) filter. At the output of the inverter and the input of PMSM, an RLC filter is connected. This filter suppresses current harmonics through filtering phase voltage harmonics. Analysis of the filter is achieved through frequency characteristics analysis.

Findings

This filter can effectively filter out the harmonic of phase voltage. Both the simulation and experiment results show that the proposed filter can effectively suppress torque pulsation and current harmonics in PMSM drives. Also, the method of selecting filter parameters and the whole control system are very simple.

Research limitations implications

The filter increases the design cost of the system.

Practical implications

The harmonics and torque ripple of phase current are greatly suppressed. Also, the loss of the PMSM reduced.

Originality/value

The method of selecting filter parameters and the analysis of the proposed filter are proposed for the first time.

Abstract

Purpose

This paper aims to design a novel feature descriptor to improve the performance of feature matching in challenge scenes, such as low texture and wide-baseline scenes. Common descriptors are not suitable for low texture scenes and other challenging scenes mainly owing to encoding only one kind of features. The proposed feature descriptor considers multiple features and their locations, which is more expressive.

Design/methodology/approach

A graph neural network–based descriptors enhancement algorithm for feature matching is proposed. In this paper, point and line features are the primary concerns. In the graph, commonly used descriptors for points and lines constitute the nodes and the edges are determined by the geometric relationship between points and lines. After the graph convolution designed for incomplete join graph, enhanced descriptors are obtained.

Findings

Experiments are carried out in indoor, outdoor and low texture scenes. The experiments investigate the real-time performance, rotation invariance, scale invariance, viewpoint invariance and noise sensitivity of the descriptors in three types of scenes. The results show that the enhanced descriptors are robust to scene changes and can be used in wide-baseline matching.

Originality/value

A graph structure is designed to represent multiple features in an image. In the process of building graph structure, the geometric relation between multiple features is used to establish the edges. Furthermore, a novel hybrid descriptor for points and lines is obtained using graph convolutional neural network. This enhanced descriptor has the advantages of both point features and line features in feature matching.

Abstract

Purpose

This study aims to propose a new airport gate assignment method to effectively improve the comprehensive operation capacity and efficiency of hub airport. Gate assignment is one of the most important tasks for airport ground operations, which assigns appropriate airport gates with high efficiency reasonable arrangement.

Design/methodology/approach

In this paper, on the basis of analyzing the characteristics of airport gates and flights, an efficient multi-objective optimization model of airport gate assignment based on the objectives of the most balanced idle time, the shortest walking distances of passengers and the least number of flights at apron is constructed. Then an improved ant colony optimization (ICQACO) algorithm based on the ant colony collaborative strategy and pheromone update strategy is designed to solve the constructed model to fast realize the gate assignment and obtain a rational and effective gate assignment result for all flights in the different period.

Findings

In the designed ICQACO algorithm, the ant colony collaborative strategy is used to avoid the rapid convergence to the local optimal solution, and the pheromone update strategy is used to quickly increase the pheromone amount, eliminate the interference of the poor path and greatly accelerate the convergence speed.

Practical implications

The actual flight data from Guangzhou Baiyun airport of China is selected to verify the feasibility and effectiveness of the constructed multi-objective optimization model and the designed ICQACO algorithm. The experimental results show that the designed ICQACO algorithm can increase the pheromone amount, accelerate the convergence speed and avoid to fall into the local optimal solution. The constructed multi-objective optimization model can effectively improve the comprehensive operation capacity and efficiency. This study is a very meaningful work for airport gate assignment.

Originality/value

An efficient multi-objective optimization model for hub airport gate assignment problem is proposed in this paper. An improved ant colony optimization algorithm based on ant colony collaborative strategy and the pheromone update strategy is deeply studied to speed up the convergence and avoid to fall into the local optimal solution.
