The purpose of this paper is to provide a new approach to incorporating uncertainty into assessing the profitability of investment projects. In the real world, the capital budgeting problem is accompanied by uncertainty and risk associated dealing with imprecise data. The major contribution of this research is the development of a novel approach to evaluating the profitability of an investment project in uncertainty condition. At first, we presented a new discount method that can be used by investors when they wants to be able to make an investment decision. That is, we developed a new method to evaluate the profitability of investment projects by or-dered fuzzy net present value (OFNPV). In addition, ordered fuzzy numbers (OFN) are used to describe the dynamics of changes of the defined investment parameters in the assumed time horizon. By using ordered fuzzy numbers, we develop an effective tool for assessing the profitability of investment projects. This assessment tool not only enables decision-makers to decide under uncertainty conditions whether or not a given investment project should be carried out or rejected, but also facilitates selecting the most effective project, e.g. a project with the most expected probability of success.

Methodology: This study was applied in terms of objective and qualitative in terms of research method. The field of research was all articles on social vitality during 1990-2022, 39 of which were selected based on inclusion criteria by purposive sampling. The data were collected by taking notes from the articles and analyzed by content analysis based on the seven-step meta-synthesis approach of Sandelowski and Barroso (2007). Findings: The results showed that 19 components and 3 dimensions were identified for a model for social vitality development. The dimensions include urban development and urban planning (6 components of compliance with the principles of urbanization and good urban governance, urban furniture design and beautification of the neighborhood, urban services and preservation of the urban environment, calming of roads and smoothing of traffic, design and construction of parks and gardens, and construction of smart parking lots), social and cultural affairs (7 components of public and morning sports, development of sports centers, development of culture and art houses, citizen health services, development of game and entertainment centers, implementation of citizenship education programs and skill training and entrepreneurship) and relations and citizenship rights (6 components of strengthening family relations, neighborhood rights, strengthening the network of friends, local cohesion and identity, resilience and the narrative of the sense of experiencing vitality in the company of friends).

One of the most fundamental executive policies of governments during development programs is creating balanced regional development. Regional inequalities are cited as reasons for growing social unrests, political instabilities, and disintegration. In Iran, these inequalities have been growing at an alarming rate leading to serious problems. So, analysis of development level of regions and consequently, identifying interregional and intraregional inequalities is of great importance in the way of adopting appropriate development policies. The aim of this study is evaluating development level of sub-provinces of Iran and exploring existent inequalities. A system of 54 indicators of different dimensions of regional development was constructed and submitted to Analytic Hierarchy Process (AHP) for this purpose. Analysis of Coefficient of Variation (CV) was also applied to reveal regional inequalities about different dimensions of development. The results of this research showed that there are obvious differentiations among sub-provinces in development level. In addition, spatial distribution of sub-provinces with regards development level indicates that an intensive system of core and periphery exists in the country. So, it is necessary to reduce regional inequalities in Iran to pave way for greater national integration, increase in economic growth and more political stability.
