Information systems (IS) are strongly influenced by changes in new technology and should react swiftly in response to external conditions. Resilience engineering is a new method that can enable these systems to absorb changes. In this study, a new framework is presented for performance evaluation of IS that includes DeLone and McLean’s factors of success in addition to resilience. Hence, this study is an attempt to evaluate the impact of resilience on IS by the proposed model in Iranian Gas Engineering and Development Company via the data obtained from questionnaires and Fuzzy Data Envelopment Analysis (FDEA) approach. First, FDEA model with α-cut = 0.05 was identified as the most suitable model to this application by performing all Banker, Charnes and Cooper and Charnes, Cooper and Rhodes models of and FDEA and selecting the appropriate model based on maximum mean efficiency. Then, the factors were ranked based on the results of sensitivity analysis, which showed resilience had a significantly higher impact on the proposed model relative to other factors. The results of this study were then verified by conducting the related ANOVA test. This is the first study that examines the impact of resilience on IS by statistical and mathematical approaches. 相似文献
This paper investigates the robustness of variance-balanced row-column designs for complete diallel cross experiments for
estimating the comparisons among the general combining ability parameters against the loss of observations. A necessary and
sufficient condition of robustness as per connectedness criterion is obtained. The robustness of optimal row-column designs
of Gupta and Choi (1998) has been investigated for the loss of any m(≥1) observations in a column and for the loss of any two observations in the design. The study of robustness has also been
conducted as per A-efficiency criterion. 相似文献
Entrepreneurial orientation and market orientation (EO and MO, respectively) have received extensive research attention in the past several decades. Although scholars widely agree that both MO and EO are critical to firms’ performances, a better understanding is still needed about how market and entrepreneurial orientation develop over time as well as their relative impact on the growth of the SME’s performance. This study does not consider MO and EO as generic resources that always positively influence firms’ performances; instead, it tries to explore contingent elements, such as social and business networks and accumulated entrepreneurial experience. The hypotheses were tested on 191 small and medium-sized electronic firms located in an Italian geographical cluster during two periods: 2005 and 2016. This study suggests that SMEs, which develop social networks, may enjoy considerable advantages from entrepreneurial and market orientation, improving their performance benefits. Moreover, our results show that previous entrepreneurial experience, when specific, can reinforce the impact of entrepreneurial and market orientation on firms’ performance growth. This analysis makes several important contributions to the management literature on the strategic orientation of firms, the entrepreneurial experience and network development.
