Viability is one of the non-functional requirements in the complex engineered systems literature which is uses for assessing the ability of complex engineered systems under uncertainty. Usually in the earlier phase of systems design and development, systems stakeholders have the request for increased value of viability and for this mean, system engineers propose several engineering changes. The main problem here is the lack of a method for analyzing the effectiveness of these engineering changes and also ranking them based on different criteria such as cost, time and risk. For promoting this gap, in this paper we propose a 11 step model for analyzing the effectiveness and also ranking the engineering changes for increasing systems viability with the use of Monte Carlo and Electre methods. The applicability of the model is shown by using illustrative example of space system datas

Because green practices are very common in industrial environments and have affected on performance.The present study investigates the effect of green supply chain management measures on performance and competitiveness in Chadormelo iron ore mine. This research is applied in terms of purpose and descriptive-survey in terms of analytical method.
The statistical population of this study is the managers and organizational experts of Chadormelo Iron Ore Company (317 people), of which 180 people were selected as a sample by simple random sampling method.Data collection tools were a localized questionnaire based on the research of Yang et al. (2013) and Younes et al. (2016).The validity of the questionnaire was confirmed by the validity criterion and its reliability was confirmed by Cronbach's alpha coefficient.Structural equation modeling and PLS software were used to analyze the data.The test of research hypotheses with the help of structural equation modeling showed that internal measures and external collaborations of green supply chain management are related to green performance and competitiveness of the company.Also, the relationship between both green supply chain management departments and the company's social performance was confirmed.On the other hand, the relationship between competitiveness and corporate social performance was positive and significant.In addition, the mediating role of competitiveness in the relationship between green supply chain management and social performance was only confirmed in terms of internal measures and external participation.Finally, it can be said that internal measures and external partnerships of green supply chain management in Chadormelo Company strengthen the company's social performance.

The purpose of this study is to identify the effect of servicescape on dysfunctional customer behavior with respect to the moderating role was customer vulnerability in restaurants in Yazd. The statistical population in the present study is the customers of a collection of selected restaurants in Yazd in 1399. The sample size of 250 participants was considered and selected by the available sampling method. Measurement tools were standard questionnaires. The results related to the direct effects of the components of the servicescape with the customer vulnerability showed the direct paths of the layout and design component to the vulnerability and the direct path of the restaurant's interior component to be significant. The results related to indirect effects showed that the indirect path of the layout and design component to the customer dysfunction behaviors is significant due to the mediating role of vulnerability, but the indirect path of the exterior environment component to the customer dysfunction behaviors is not significant due to the mediating role of vulnerability. The results related to the moderating effects of customer vulnerability in predicting customer dysfunction behaviors concerning environmental components with customer dysfunction behaviors are not significant. it can be said that the servicescape leads to customer satisfaction with the services received and at the same time can reduce the vulnerability that is caused by the loss of well-being in receiving services and the satisfaction that reduces the sense of loss of well-being can lead to a reduction in customer dysfunction behaviors.
