Purpose Nowadays, to develop innovative activities in research and development units, it is desirable to rely on the concept of open innovation to take actions towards the identification of external capabilities of an organization and external knowledge acquisition. Therefore, this study aims to evaluate the impact of external technology acquisition (ETA), external technology exploitation (ETE) and culture of innovation (IC) on open innovation (OI) using SEM approach and then examine the amount of the impact of open innovation on organizational performance (OP) and value creation (VC). Design/methodology/approach This study was an applied survey in terms of research purpose and data collection method. The statistical population included all companies in Yazd Science and Technology Park (STP). To collect the data, 109 questionnaires were distributed. The content validity of the questionnaire was confirmed by experts’ comments, and Cronbach’s alpha coefficient was calculated equal to 0.873 for reliability. Findings The results indicated, ETA, ETE and IC had significant and positive effects on OI, and OI by itself had a significant and positive impact on OP and VC. However, the hypothesis of the significant and positive effect of VC on OP was rejected. Originality/value Considering the importance of innovative activities of companies in STPs and the role of OI in achieving the goals of idea-driven companies, the present study evaluated the effects of factors affecting the fulfillment of OI in companies based in STPs in the Yazd province of Iran.

The development of a scientific discipline is partly determined by the growth of its literature. Bibliometrics constitute a set of mathematical and statistical techniques employed to explore, organize, and quantitatively analyze large pools of scientific literature. In this study, 11,433 papers published between 1974 and 2015 are collected and analyzed by applying life-cycle analysis, bibliometrics and text mining in order to provide a full thematic overview of the application of fuzzy theory in operations management. Top countries (i.e. the most productive, influential and collaborative countries), most frequently cited journals, and key research topics are identified by employing bibliometric techniques. Finally, the articles' common research themes and methodologies are determined by combining text mining with experts' input. Results show that the application of fuzzy theory in operations management is still in its infancy, and hence suitable for future research. This study serves as a guide for researchers to identify the hidden patterns, key actors, topics, and methods in this area.

Purpose According to the definitions presented for agility drivers, it can be mentioned that supply chain risk factors in terms of feature have very close roles to agility drivers and both of these factors impact the uncertainty in the environment. However, the risk factors with a wider domain are more comprehensive. This study aims to examine the effectiveness of risk as a driver on the organizational agility. Design/methodology/approach To conduct the research, after identification of influential risk factors of supply chain and indicators of organizational agility, questionnaires needed for the research were designed and after confirming their validity and reliability were distributed among the member of the sample. To assess the relationship between supply chain risk and the amount of organizational agility, data obtained from the questionnaires were analyzed using structural equation modeling technique. Findings The results of data analysis showed that supply chain risk factors could be considered as a driver affecting the organizational agility. In addition, in this study, supply chain risk factors were ranked using interpretive structural modeling. The presented comprehensive model indicated that based on causal relationships between risk factors, sovereign risk as the basis for model (three levels) and product and customer satisfaction risks as the output of the model (Level 1) were considered. Originality/value This paper fulfills an identified need to study how the risk factors as drivers of supply chain agility can have effect on agility.

Purpose The purpose of the paper is to bring attention to documentary credits and the efforts to reduce debt obligations in credit history is recognized as an important source of uncommitted bank earnings. Credit risk has a significant impact on the stability of the banking system. This paper identifies the types of credit risk in the banking supply chain. Design/methodology/approach The authors model the types of credit risk using the intuitive fuzzy failure modes and effects analysis (IFMEA) and intuitive fuzzy cognitive mapping. The population of the study that is needed for the interviews and expert panels comprises senior managers and experts of a leading bank in Iran. The respondents are experienced in credit and banking risk and were selected through judgment sampling and snowballing. Findings The findings suggest that reducing the risks of the foreign letters of credit contracts can mitigate the risk in the agricultural sector, the specific risks of rent-to-own contracts, the risk of the long-term facilities and the specific risk of the domestic letter of credit contracts. Originality/value This research investigates Iran Tejart Bank’s credit risk, formulates a model of the types of credit risk present and analyzes them using the intuitive fuzzy failure modes and effects analysis and intuitive fuzzy cognitive map. Through this credit risk model, one can then facilitate risk management for better financial stability. Also, the model can be used to evaluate the risk indicators.
