Abstract
Purpose
This paper aims to investigate the equivalent relationship between accelerated corrosion tests and real environmental spectrum of suspenders in long-span suspension bridge considering multiple factors action.
Design/methodology/approach
Based on Faraday's law, corrosion current was used as a measure of metal corrosion, and the equivalent conversion relationship between laboratory environment and real service environment was established. The equivalent conversion method for bridge structural steel had been determined under different temperature, humidity, pH value and NaCl concentration conditions. The compilation of environmental spectra for large span bridges considering multiple factors and the principle of equivalent conversion have been proposed.
Findings
Environmental factors, including temperature, humidity, pH value and NaCl concentration, have significant impact on the corrosion degree of suspension steel wires, and only considering these two factors for equivalent conversion cannot accurately reflect the true service environment of the bridge. The 33.8-h salt spray accelerated corrosion test using the standard conditions can be equivalent to one year of suspenders corrosion in a real service environment.
Originality/value
The equivalent accelerated corrosion method for steel wires proposed in this study can effectively predict the corrosion degree of the suspenders, which has been verified to be correct and can provide theoretical guidance for the development of corrosion test plans for steel wires and engineering technical basis for anti-corrosion control and calendar life research of suspension bridge suspenders.

Abstract
Purpose
Open innovation and information systems have been key topics in the theoretical domain, but little empirical research thoroughly examines how information technology (IT) capability affects open innovation performance. Thus, the purpose of this paper is to explore the relationship between IT capability and open innovation performance and to expose the inner mechanism at the firm level.
Design/methodology/approach
This paper collected firm-level data in China; 232 usable questionnaires from different firms were collected. Then, the study used a structural equation model by AMOS for hypothesis testing.
Findings
The results indicate that both internal IT capability and external IT capability have positive impacts on open innovation performance; potential absorptive capacity and realized absorptive capacity mediate the relationship between external IT capability and open innovation performance. Additionally, realized absorptive capacity plays a mediating role in the relationship between internal IT capability and open innovation performance.
Practical implications
These findings indicate that practitioners should pay attention to the important relationship between absorptive capacity and IT capability and open innovation performance in Chinese businesses.
Originality/value
Existing research has emphasized the influence of IT on open innovation, but empirical studies have not thoroughly focused on the inner mechanisms of the effect of IT capability on open innovation performance. Drawing on firm capability theory, this paper classifies IT capability as internal and external IT capability and absorptive capacity as potential and realized absorptive capacity. Then, this paper confirms the mediating role of absorptive capacity between IT capability and open innovation performance.

Abstract
Purpose
More enterprises adopt open innovation by breaking technological or organizational boundaries to seek internal and external knowledge when they face a fiercely competitive environment, complex market demands, and increasingly rapid technological change. In this context, a knowledge search strategy is regarded as an effective means of obtaining inside and outside resources and an important way to break the innovation bottleneck. Moreover, information technology (IT) is deemed an important asset for sourcing knowledge, whereas absorptive capacity is seen as an indispensable ability for utilizing novel knowledge. Thus, this paper aims to test the role of knowledge search in open innovation and examine the mediating effect of absorptive capacity and the moderating effect of IT capability.
Design/methodology/approach
Using a sample of 1,088 Chinese firms’ data collected by the World Bank in 2012, this paper employs logistic regression to test the hypotheses.
Findings
This study finds that local and boundary-spanning search strategies positively influence both product and process innovation, and absorptive capacity has a mediating role in the relationships between knowledge search and product and process innovation. Moreover, IT capability has a positive moderating effect on the relationship between local search and innovation performance; however, IT capability strengthens the relationship between boundary-spanning search and process innovation while weakens that between boundary-spanning search and product innovation.
Originality/value
This study explores the impact of different knowledge search behaviors on different types of innovation and probes the role of absorptive capacity and IT capability in mediating and moderating the above relationships. By drawing on knowledge-based theory and cognitive-developmental theory, this paper provides a novel perspective to explain the mechanism between knowledge search and innovation performance.

Abstract
Purpose
Intuitionistic linguistic fuzzy information (ILFI), characterized by linguistic terms and intuitionistic fuzzy sets (IFSs), can easily express the fuzzy information in the process of muticriteria decision making (MCDM) and muticriteria group decision making (MCGDM) problems. The purpose of this paper is to provide an overview of aggregation operators (AOs) and applications of ILFI.
Design/methodology/approach
First, some meaningful AOs for ILFI are summarized, and some extended MCDM approaches for intuitionistic uncertain linguistic variables (IULVs), such as extended TOPSIS, extended TODIM, extended VIKOR, are discussed. Then, the authors summarize and analyze the applications about the AOs of IULVs.
Findings
IULVs, characterized by linguistic terms and IFSs, can more detailed and comprehensively express the criteria values in the process of MCDM and MCGDM. Therefore, lots of researchers pay more and more attention to the MCDM or MCGDM methods with IULVs.
Originality/value
The authors summarize and analyze the applications about the AOs of IULVs Finally, the authors point out some possible directions for future research.

Abstract
Purpose
The purpose of this paper is to overview the development of China's emission trading, which is transforming environmental policy measures from traditional command and control regulations to business‐led decision making within government initiated environmental markets, and investigates the main factors that affect China's policy making with regards to further climate changes.
Design/methodology/approach
This paper is based on the authors' review of the literatures on emissions trading program in China and their critical analysis.
Findings
Initially China's environmental protection policies were focused principally upon the reduction of sulfur dioxide (SO2) emissions for improving air quality. Since the authorization of the Kyoto Protocol in 2002, project‐based activities such as Clean Development Mechanism producing carbon credit developed rapidly. However, the implementation of carbon dioxide emission trading is still under discussion and research is much inferior to that of SO2 emission trading. The barriers of and suggestions for designing future emissions trading market are also discussed.
Originality/value
This review helps to raise awareness and understand possible scenarios for emission trading in China.

Abstract
In this chapter, an air cargo shipment planning problem is considered by including individual risk factors of any sub-contracted agents. Due to competitive market conditions, air cargo forwarders are advised to remain flexible in operations. A mixed integer linear programming formulation including the potential for divisible activities is developed to model the shipment planning problem. To solve this complicated problem, we employ an ant colony optimization (ACO) methodology. Numerical examples are generated using data from both the extant literature and from a global air cargo company, allowing investigation of the viability of the novel methodology. We find that the algorithm/methodology provides effective solutions for small problem sizes.

Abstract
Purpose
The purpose of this work is to illustrate the processes involved in managing teams in order to assist designers and developers to build software that support teamwork. A deeper investigation into the role of team analytics is discussed in this article.
Design/methodology/approach
Many researchers over the past several decades studied the success factors of a team. Despite many efforts, there is still no consensus on how a team should ideally be formed. Consequently, how one decides to form teams in a class depends on the domain, classroom context and pedagogical objectives. Therefore, software used to support an instructor in forming teams must be flexible enough to accommodate a variety of use cases and support the users throughout the lifecycle of teamwork. In this work, the author proposes a framework for designing general-purpose team management software. The author reviews existing team formation software and focuses specifically on opportunities for advancing research in team analytics.
Findings
In this context, the author identifies four areas of research opportunities for team analytics.
Originality/value
Lastly, the author proposes a series of research questions (RQs) and discusses the pedagogical, design, technical and social challenges involved.
