The purpose of project risk management is to improve project performance by systematically identifying and assessing risks, developing strategies to reduce or avoid them and maximizing opportunities. The literature review depicts that there is still a significant gap in the field of risk response assessment and selection. The relevant studies mainly comprise of conceptual models that capture effects of uncertainty on projects and strategies to reduce the level of risk. In order to overcome these drawbacks, this paper proposed a practical framework that integrates the project work breakdown structure, risk events, risk abatement actions, secondary risks and their effect. The problem is modeled as a multi- objective optimization problem. We use a fuzzy prioritization approach for calculating the coefficients of the objective function. We develop exact and heuristic methods for the proposed model. Furthermore, a case study in Iranian power plant projects is presented to show applicability and performance of the proposed model. The results show considerable time, cost and quality improvement.

This paper is a field research attempt aimed at the “Design and Analysis of a model affecting organizational، group and individual factors in Innovation Promotion in Research &Technological organizations of Iran.” The research results show that the organizational and group and individual factors Affects the Innovation Promotion in the Research &Technological organizations. This study tries to present and examine a model which can reflect the impact of the internal factors on Innovation Promotion in industrial organizations، and as well as to evaluate، the effectiveness of each organizational، individual and group factors and their components on the Innovation Promotion in the Research organizations. The statistical society of the research includes the Research &Technological organizations of Iran in which Homogeneous research centers and 312 managers and researchers have been chosen based on the “Known Group” sampling method. This study used survey research methodology and its tools are also questionnaires. The reliability of the survey has been calculated using Cranach''s Alpha method which is equal to 0. 928. To analyze the data، it was necessary to first evaluate the credibility of the theoretical model through LISREL software. The results verify that the model is acceptable for the statistical society. The calculated path coefficients also show that the organizational factors (includes structure، learning، leadership، strategy، reward system، employees’ participation components)، group factors (includes communication، combining، Cohesiveness، size of the group components) and Individual factors (includes individual skills and abilities، personality characteristics، motivation components) have a strong relationship with the encouragement of innovation and have a positive effect.

The electronic learning fundamental factors are considered critical because they affect the ability of human resources. This study investigated the influence of electronic learning fundamental factors on the innovation in performance through knowledge management capacity. In this study with survey research approach، 72 cases of active members in research and development teams inthe Buali industrial zone and companies of surrounding the city of Hamadan were selected as examples. Data were obtained through standard and endemic questionnaires. Validated tools to help them with the help of factor analysis and Cronbach''s alpha reliability was confirmed. Also، the analysis was performed with the software smart pls. The results showed that research model is a strong theoretical model for predicting innovations in performance through electronics training fundamental factor and knowledge management capacity. Thus، success in performing these factors، along with improved knowledge management capacity will be result to promote innovation in employee performance.

Predicting the demand for urban water helps the managers and users of urban water systems to a great extent in order to manage properly in this regard. To do so، exact predicting of the demand for water is of great importance in different periods. In this study، by using a method which is combination of linear and non-linear models، daily demand for water in Tehran and the effective factors on daily demand has been studied. Daily demand for urban water is predicted step by step based on ARMA models، Artificial Neutral Network، and the combined model for the next 10 days. To design Artificial Neutral Network and the combined model، the effective factors on daily demand for urban water، temperature (minimum، maximum، and average (medium))، weekly days، holidays، and the special days are considered. The results obtained from using criterion for accuracy evaluation show that the combined model has fewer error and high accuracy for this propose and Artificial Neutral Network and ARMA process are in next priorities.

This paper aims to analyze the relationship between value perceptions، commitment، and intention to use mobile banking services. For this purpose، a model، consisting fourteen hypotheses، tested with regard to literature review. The statistical population of this research is mobile banking users in Mashhad، Iran. Convenience sampling applied in this study since there was not a certain database. The research tool is a Likert 5-points scale by which we gathered attitudes of 93 users of mobile banking. Structural equation modeling by SMART-PLS software package used to test the data. The results show that commitment to banking service provider، commitment to use mobile channel and intention to use mobile channel affect intention to use bank service provider positively and directly. They showed also that hedonic value influences it positively but indirectly.

Trade policy is one of the most important segments of a nation-state economic policy. The public policymaking in the segment includes developing long and mid-term plans to direct the decision making process on export، import and foreign investment in a country، by which businesses (either private or public) will be able to perfume more effective in international level and foreign marketplaces. On the other hand، in recent three decades globalization forces of economic، political and cultural scales have great impacts on the societies in different ways. In the paper، a model has been suggested to explain the impacts on trade policymaking process of I. R. Iran. Ministry of Commerce، however، was attained as the research source of data، due to the main role of the ministry on trade policy of Iran. The results indicate that economic، political and cultural forces of globalization have great impacts on trade policymaking process and probably would improve level of participation in planning and enhance trust and commitment of policymakers to the policy network.
