The majority of supply management models are limited to physical products and few are designed for service items. Therefore, this paper is aimed to propose dimensions, components and indicators of a multidimensional portfolio model for service supply management in the mobile operator industry.

Combining the three high-cited models in the literature background, and adding a new dimension through in-depth interviews with the experts, a four-dimensional multilevel relational reflective model has been proposed for service supply management in the mobile operator industry. This model has been built up using the Fuzzy Delphi method and its goodness of fit has been confirmed through factor analysis.

The final model has been applied in MCCI company and 50 services procured by the company has been classified into 16 groups. Then, for each group, based on the the literature background, along with using the focused group technique, the pertinent supply strategic actions have been proposed.

The model extracted from this study consists of four dimensions: the strategic importance of service, the risk of supply market, the extent of buyer captivity and the pace of innovation in technology, which totally contains 11 components and 33 indicators. All the services provided by the mobile operators can be classified in 16 clusters related to four main dimensions.

Aims and goal:

 Management consulting is a service to help organizations increase productivity, and making good use of consultants' experiences will reduce the costs of trial and error. Due to the importance of marketing consulting services, this study aimed to identify the factors influencing the promotion of management consultants personal brand and model of management consultants personal brand.

The present study is a descriptive research in terms of purpose and is an applied- survey research in terms of it’s used type. The research variables were measured by a researcher-made questionnaire. The statistical population consisted of 15 experts in the field of consulting. These were selected by purposeful judgment.

Based on the results of the data analysis with confirmatory factor analysis, the factors influencing consultants' personal brand promotion were categorized into four categories: individual, occupational, environmental- social and technological.

Developing and maintaining a personal brand enables consultants to outperform their competitors in the field of professional competition and create a competitive advantage by investing in the aforementioned four factors.

As nobody can prevent disasters like earthquake, tsunamis, hurricanes, floods and etc. and because of huge harmful effects of the events, in recent years, scientists mostly try to find the best way to control undesirable consequences of these events. According that Emergency decision making EDM is a way of emergency management to control the bad effects of these disasers. EDM used for rescue units that their mission is going to critical places and save the lives and properties, must be found location and allocated to places that crisis occur there. This paper presents two scenarios that each one contain multi objective decision support model to find a location to establishment of critical bases and allocate rescue units of primary nodes to each crisis. During this action three main objectives of these kind of problems considered. First goal of the (MILP) models for each scenarios is minimizing sum of all severity of crisis delays of rescue unit to reach the critical places. The second goal of the problem minimizes total arrival time rescue units at critical places. As the third goal the model minimizes total costs of this transportation. These three objectives ranked by priority. The difference between two scenarios is that first scenario crisis is predected and dosen't occured but in second scenario crisis existed by raid. Then to illustrate the efficiency of the model a numerical example solved by GAMS and results is showed.

This study aims to explore the effect of innovation capability on technology commercialization performance in Knowledge-Based Companies by considering the mediating variable of organizational innovation.

The present research is applied in a practical, descriptive and survey-oriented way. The statistical population of this research consists of 99 top managers of Knowledge-Based Companies in modares’s Science and Technology Park. A randomized stratified sampling method was used to select the statistical sample. Using Cochran sampling formula(10% error), the number of sample member was calculated to be 87 people. At the end, 81 questionnaires were correctly filled. In order to analyze the data, the Structural Equation Modeling based on partial least squares method has been explioted using Smart PLS software.

The results of analysis of research hypotheses showed that innovation capability has significantly positive effects on the technology commercialization performance. Moreover, organizational innovation mediated the relationship between innovation capability and technology commercialization performance.

Creating competitive advantage and survival of knowledge-based companies is a continuous enhancement of innovation capability, providing a framework for the development of organizational innovation, and enhancing technology commercialization.

This research is aimed at investigating the multilevel transformational leadership on the innovative behavior of employees because organizations are multilevel systems. The statistical population of this research is the Directorate General of Cultural Heritage, Industries and Tourism of Tehran Province, which includes 40 managers and 250 employees. The Cochran formula was evaluated by stratified sampling of 36 managers and 151 employees. The validity of the questionnaire was Dassil and Dehar (2015), its reliability by calculating Cronbach's alpha and CR index, and its validity by content validity methods, convergent and divergent validity was confirmed. The results showed that transformational leadership has a positive and significant effect on the innovation climate . Also, the innovation climate on the innovative behavior of employees , transformative leadership on the innovative behavior of employees , and the moderating effect of creative self-efficacy on the relation of innovative atmosphere to the innovative behavior of employeesThe data are analyzed using HLM analysis software. The output of HLM 7 software represents the multilevel relationships of the research variables. In this research, the effect of transformational leadership on both individual and It's at the group level. Transformational leadership has an impact on the innovative behavior of employees, at the individual and group levels, on the influential atmosphere. From the important findings of this multivariate analysis, the effect of moderating creative self-efficacy (individual level variable) on the relationship between individual and group factors

This study focuses on the mediating role of work engagement on relationship between social exchange of organization and innovative work behavior. Following the previous studies in the literature, leader-member exchange and perceived organizational support are considered as social exchange between organization and members. Statistical sample includes 310 staff members of Iran National Steel Industrial Group (NSIG) selected using a simple random sampling method. Standard questionnaires have been used for gathering the information from respondents. According to Cronbach Alpha calculation in SPSS environment, the reliability of questionnaires seems to be quite reliable and the validity of questionnaires has been confirmed by face and content validity approaches. The research hypotheses have been investigated by structural equation modeling (SEM) in Smart-PLS environment. The findings show that leader-member exchange and perceived organizational support positively and significantly influence on the innovative work behavior, leader-member exchange and perceived organizational support positively and significantly influence on work engagement, and work engagement positively and significantly influences on innovative work behavior. Furthermore, the study indicates incomplete mediating role of work engagement on the relationship between organization social exchange and innovative work behavior.
