تعداد بازدید : ۱۲۴ تعداد دانلود : ۱۵۸
In this paper, a fractional multi- objective multi- product solid transportation problem with interval costs, supply, demand, and conveyances is investigated based on fuzzy programming approach. To minimize the problem, the order relations that represent the decision maker's (DM) performance between interval costs, supply, demand and conveyances are defined by the right limit, and the left limit. Through the deterministic problem is obtained, a fuzzy programming approach is applied by defining membership functions. A linear membership function is being used for obtaining optimal compromise solution. Finally, a numerical example is given to the utility of the approach.

Entrepreneurial ecosystem is a geographic framework that indicates that a person is supported by which factors for becoming a businessman. Effective factors on this issue include social, cultural, political and economic structures that should be considered in the context of different regions. In our research, we are going to identify not only international and national factors affecting entrepreneurship but also factors that will affect on the entrepreneurship of the region. The statistical sample includes 100 entrepreneurship development policymakers, entrepreneurs, and owners of knowledge-based companies. The data gathering tool of the interview was based on a closed questionnaire and the validity and reliability of this research were confirmed after the assessment. Based on the findings of this study from the descriptive aspect, this conceptual model has been appropriate for experts and entrepreneurs. Analysis of the main goals of the research shows that there are a number of factors on the region that the ecosystems of entrepreneurship are affected by them, which include geographic, demographic, institutional factors, and regional infrastructure.

In this research, researchers deal with the study of the antecedents and consequences model of the brand attachment in the form of CBR. In this study, consumer-brand relationships are divided into two kinds: communal and exchange ones. The statistical society totally consists of 864 students of the marketing in Tehran City. The available relationships in the model are separately examined by using the structural equations modelling (AMOS 5.0) within each group in order to test the model and hypothesis. The results of the research show that the variables including brand experience, brand love, commitment, trust, in the communal group play a more effective role than the others in producing the brand attachment, also the variables such as brand reliability, brand satisfaction in the exchange group are among the fundamental ones for developing the brand attachment. This study is the first attempt to identify the importance of relationships aspects in young adult consumer. The current study extends branding literature by shedding lights on the roles of communal/exchange relationships factors in brand management, which also help brand managers.

The rapid development of communication technologies and information and online computers and their usage in processes of the industrial production have facilitated simultaneous monitoring of multiple variables (characteristics) in a process. In this work, we applied boosted decision tree and Monte Carlo simulation to propose an efficient method for detecting in-control and out-of-control states in multivariate control processes.In this work, four classifiers (methods) - , , , – are used for detecting the process control states. Then, with converting detection results these four classifiers, the boosted decision tree is made and provides the ultimate result as the in-control or the out-of-control states. To show how the proposed model works and the superiority of this method over , , , and methods, we run it on a standardized trivariate normal process. To compare and evaluate the performance of classifiers, we used ARL functions and the evaluation measures including Accuracy (ACC), Sensitivity (TPR), Specificity (SPC), and Precision (PPV). The findings not only showed the superiority of the proposed method over the tradition Chi-square but also confirmed former results on the efficiency of decision tree for rapid detecting of mean shifts in multivariate processes in which data are gathered automatically.

Supply chain integration represents the extent based on which a producer strategically cooperates with its supply chain partners and collaboratively manages inter-organizational and intra-organizational processes. The current research has been conducted to examine the effect of supply chain integration on operational efficiency and value creation. In order to do this, Annan’s et al. (2016) standard questionnaire was used to measure the research variables. The research method was descriptive correlational. In order to answer the research questions and investigate the research hypotheses, structural equations and path analysis by means of the partial least squares method (PLS) were used with Smart-PLS software. The obtained results indicate that there is a positive and significant relationship between the inter-firm networking resources and dysfunctional competitions on the supply-chain integration. The results also approve the positive and significant effect of supply chain integration on customer value creation and the company’s operational efficiency.
