Abstract
Purpose
Profile measurement with boundary information plays a vital role in the detection of quality in the assembly of aviation parts. The purpose of this paper is to improve the evaluation accuracy of the aerodynamic shapes of airplanes, the profiles of large-sized parts need to be measured accurately.
Design/methodology/approach
In this paper, an accurate profile measurement method based on boundary reference points is proposed for the industrial stereo-vision system. Based on the boundary-reference points, the authors established a priori constraint for extracting the boundary of the measured part. Combining with the image features of background and the measured part, an image-edge compensation model is established to extract the boundary of the measured part. The critical point of a laser stripe on the edge of the measured part is extracted corresponding to the boundary constraint. Finally, as per the principle of binocular vision, the profile of the measured part is reconstructed.
Finding
Laboratory experiments validate the measurement accuracy of the proposed method which is 0.33 mm. In the analysis of results between the measured data and the theoretical model, the measuring accuracy of the proposed method was found to be significantly higher than that of the other traditional methods.
Practical implication
An aviation part was measured in the part-assembly shop by the proposed method, which verified the feasibility and effectiveness of this method. The research can realize the measurement of smooth surface boundary which can solve existing profile reconstruction problems for aviation parts.
Originality/value
According to the two-dimensional contour constraint, critical points of the laser strip sequence at the edge of measured part are extracted and the accurate profile reconstruction with the boundary is realized.

Abstract
Purpose
The purpose of this paper is to present a new method and model for determining the optimal decision-making for the pricing strategy to the Fuji apple in Shaanxi of Chain which is representing fresh agricultural products under the e-commerce environment.
Design/methodology/approach
Considering the rapid development of information technology as well as internet that actually motivate the e-commerce, Fuji apple is a distinctive product in China’s Shaanxi; its sales channels have extended to online sales under the wave of e-commerce. Internet trading platforms make it possible to trade online in real time between suppliers and customers who live in different geographical areas. In this paper, the authors study how to price online to maximize the total revenue. The challenge is to optimally price two different qualities of apple. Based on the consumer surplus theory, the authors use the method that builds the function of the relationship between the proportion of consumers purchasing different qualities of products and price.
Findings
This paper presents a generalized model to determine the optimal pricing that maximizes the total revenue of a fruit grower over a finite planning horizon. The authors divided discount into two intervals and discussed the optimal discounting and pricing at both intervals. Then they determined the optimal pricing strategy for Fuji apple in Shaanxi of Chain under the e-commerce environment.
Originality/value
This paper makes up for the lack of existing studies of pricing under the e-commerce environment. A new method and approach to the traditional pricing strategy is established and applied to a management decision-making problem with Chinese characteristics in reality.

Abstract
Purpose
A growing number of studies have become focused on managing conflict more effectively and comprehensively in the construction industry. However, little research has aimed to operationalize all the facets related to the quality of conflict management that are necessary in governing conflict management. The purpose of this article is to propose a new model measuring the quality of conflict management in a construction project context that is not only inclusive but also practical.
Design/methodology/approach
To address this research gap, the authors used the measurement theory to investigate a series of studies, and then, developed a scale to operationalize the concept of quality of conflict management in a project context.
Findings
The findings show five dimensions to the quality of conflict management: satisfactory resolution outcome, integrated resolution process, conflict prevention, fairness perception, and post-conflict effect.
Originality/value
The research findings contribute to conflict management theory by providing the conceptualization and operationalization of conflict management quality. Practitioners will benefit from this article by understanding effective and efficient ways of managing conflicts in construction projects.

This study explores the link between additional reviews, credibility, and consumers’ online purchasing behavior.
Abstract
Purpose
This study explores the link between additional reviews, credibility, and consumers’ online purchasing behavior.
Design/methodology/approach
We employ a 2 × 2 between-subjects design to measure subjects’ purchasing behavior with versus without additional reviews and with important versus non-important attributes. A total of 529 valid questionnaires are collected from university students across 30 Chinese provinces.
Findings
The addition of negative reviews to a positive initial review enhances consumers’ perceived credibility of the reviewer and the overall review content. This effect is positively moderated by the attribute importance in additional reviews. Moreover, we find that as the time interval increases, consumers’ perceived credibility gradually increases but eventually decreases after reaching a certain threshold. In addition, the attribute importance in additional reviews negatively moderates the impact of perceived credibility on consumer purchasing behavior.
Originality/value
Existing studies on first and subsequent reviews mainly focus on the difference in perceived usefulness between the two. They do not examine how additional reviews affect potential customers’ perceived credibility and their purchase decision-making. This study bridges the gap between the word-of-mouth literature and marketing practices.

Abstract
Purpose
At the center of apple production province in China, how to increase apple per unit yield and to improve apple production efficiency in Shaanxi become big issues. The objectives of this paper are to investigate the technical efficiency (TE) and cost efficiency (CE) of apple orchard and to analyse determinants which affect apple production efficiency. The paper aims to discuss these issues.
Design/methodology/approach
This paper conducts a two‐stage DEA to achieve the objectives. In the first‐stage, a cost minimization model is applied to measure apple production efficiency. Then, a Tobit model is provided to estimate regression coefficients which are used to adjust the efficiency scores in the first‐stage.
Findings
The results indicate that TE and CE are rather low in Shaanxi. The research also explores that the inefficient production of apple farmers is caused mainly by two aspects. One is the inefficient apple orchards operation of farmers. The other is the disadvantageous environmental conditions which heavily affect apple growth and fruit bearing situation.
Originality/value
Most of the research are based on national statistical data, and only measure the TE. This paper primarily focuses on the estimation of efficiency scores with the data involved in both quantity and price information of traditional inputs and outputs based on 255 apple farmers in Shaanxi. Specifically, This paper also consider farmer's opportunity cost to which little literature refers. The results not only reveal the efficient determinants of apple production, but also provide suggestions for agricultural policy makers.

Abstract
Purpose
This paper aims to clarify the functions of tourism interpretations of consumer products in a tourist-generating region (TGR) as a means of marketing the tourist destination region (TDR) through tea tourism.
Design/methodology/approach
This is a case study of the Thai Shizuoka Green Tea brand working to promote tea tourism in Shizuoka, Japan. It is used to identify the functions of tourism interpretations of consumer products in a TGR related to the concept of brand identity. This paper assessed Thai consumers’ opinions on the efficiency of tourism interpretation through a sample of 404 questionnaires and with interviews of ten young females, the primary respondents.
Findings
Tourism interpretations of the TGR’s consumer products are important for promoting the TDR through five premises: 1) motivating visitors to visit the destination, 2) communicating the place’s meaning, 3) targeting potential tourists, 4) differentiating the destination from other sites and 5) activating value co-creation. Premises 1 and 2 were assumed to stem from visitors’ enjoyment of the tea; the packaging motivated their visit to Shizuoka, its origin. Premise 3 concerns young women who view the product as a premium healthy drink. Premises 4 and 5 are based on the brand’s essence, implying the tea company’s partnership between Thailand and Japan.
Originality/value
Tourism interpretation plays a significant role in TDRs’ success; however, it can be implemented with other consumer products and an efficient brand identity, to create an image of a destination.

Abstract
Purpose
This paper aims to establish the predictive equations of height, area and volume of printed solder paste during solder paste stencil printing (SPSP) process in surface mount technology (SMT) to better understand the effect of process parameters on the printing quality.
Design/methodology/approach
An experiment plan is proposed based on the response surface method (RSM). Experiments with 30 different combinations of process parameters are performed using a solder paste printer. After printing, the volume, area and height of the printed SAC105 solder paste are measured by a solder paste inspection machine. Using RSM, the predictive equations associated with the printing parameters and the printing quality of the solder paste are formed.
Findings
The optimal printing parameters are 175.08 N printing pressure, 250 mm/s printing speed, 0.1 mm snap-off height and 15.7 mm/s stencil snap-off speed if the target height of solder paste is 100 µm. As the target printing area of solder paste is 1.1 mm × 1.3 mm, the optimized values of the printing parameters are 140.29 N, 100.52 mm/s, 0.63 mm and 20.25 mm/s. When both the target printing height and area are optimized together, the optimal values for the four parameters are 86.67 N, 225.76 mm/s, 0.15 mm and 1.82 mm/s.
Originality/value
A simple RSM-based experimental method is proposed to formulate the predictive polynomial equations for height, area and volume of printed solder paste in terms of important SPSP parameters. The predictive equation model can be applied to the actual SPSP process, allowing engineers to quickly predict the best printing parameters during parameter setting to improve production efficiency and quality.

Abstract
Purpose
The purpose of this paper is to advance a proactive perspective on business exit and develop a typology of exit strategies.
Design/methodology/approach
This is a research paper, which builds on extant theoretical and empirical research.
Findings
Business exit, along with entry, is an integral part of corporate strategy that a firm could utilize to reshuffle its business portfolio and embrace new opportunities. In today’s changing environment characterized by high uncertainty and high velocity, it becomes increasingly important for firms to manage business exit deliberately and proficiently. The traditional perspective which generally perceives exits as failures or responses to failures is no longer sufficient. A proactive perspective on exit could be advanced to better inform exit research and practice. Adopting the dynamic capabilities approach, this paper develops a typology of four exit strategies – retreat, redeploy, realign, and reconfigure – and examines the essential tasks of these strategies as well as the corresponding dynamic capabilities required for their successful implementation.
Originality/value
The proactive perspective advanced in this paper systematically coalesces and elaborates on extant research and formally advocates the importance and feasibility of proactive exit. The typology offered not only helps integrate the dynamic capabilities approach with exit research but also helps better inform exit practice.

Abstract
Purpose
The purpose of this paper is to determine the development and knowledge flows of dye-sensitized solar cells (DSSCs) via the use of patent inventor database. Moreover, this study aims to explore patentees and inventors’ companies to help readers and practitioners to be able to understand the patentees, technology development and activities of knowledge flows from four countries. DSSCs, which are known as one of the key technologies of green energy, have been applied ever more widely to many different industries, and their use has quickly grown with a number of scientific publications and patent applications.
Design/methodology/approach
This paper was based on the US patent database collection of third-generation DSSCs in four typical countries such as USA, Japan, Germany and Taiwan to map the knowledge network of DSSC technology via the social network analysis method.
Findings
The knowledge network of 132 DSSC patents was explored. Among the four countries, Japan leads, with the main patent number being H01G009. This paper also indicates the knowledge flow situation of Japanese inventors of DSSCs. For example, patented inventors Wariishi and Koji (JP) served the Fuji Photo Film Co., Ltd. (JP) in 2002, and then in 2008, transferred to the Fuji Film Corporation (JP). This means that the knowledge of technology was transferred by people who moved to another company for a new job.
Research limitations/implications
This study is based on US Patent and Trademark Office patent database to do exploration.
Practical implications
This study was expected to provide information for the industry, government and academia, so that they will understand the trajectory of the technology inventor, specialist cultivation and technology development in the DSSC industry.
Originality/value
This study provides useful information for the green energy industry, government and academia to understand the importance of the knowledge flows and future development of DSSC technology of the solar cell industry. Thereby, they can intensify industrial competence and innovation by externally collaborating in this field as well as to increase the industrial competence by reimbursing the funds from government and other research institutes.
