    Developing a model for integrating decisions in technology roadmapping by fuzzy PROMETHEE

    , Article Journal of Intelligent and Fuzzy Systems ; Volume 26, Issue 2 , 2014 , Pages 625-645 ; ISSN: 10641246 Ghazinoory, S ; Daneshmand Mehr, M ; Arasti, M. R ; Sharif University of Technology
    Abstract
    Roadmapping, a tool of strategic planning, visualize where and how an organization will be in the future. Visualization of strategic programs assists people in the organization to understand the strategy which is a key for implementing strategy successfully. A generic roadmap is included of three main layers such as; market, product and technology. Decision making in each layer are done separately because of the nature of each layer. Therefore, decisions in roadmapping can be done with different tools. Whiles, decisions in each layer of the roadmap cannot be done without considering the upper or lower layer decisions. In this study we propose Fuzzy PROMETHEE method for integrating decisions... 

    Formulating directional industry strategies for renewable energies in developing countries: The case study of Iran's wind turbine industry

    , Article Renewable Energy ; Volume 39, Issue 1 , 2012 , Pages 299-306 ; 09601481 (ISSN) Bagheri Moghaddam, N ; Mousavi, S. M ; Moallemi, E. A ; Nasiri, M ; Sharif University of Technology

    Abstract
    This study seeks a method for formulating directional strategy of wind turbine industry in Iran. To this end, by initially evaluating various economic viewpoints concerning the development of industries, the necessity of government intervention is recognized. By defining the concepts of national industry policy, firm technology strategy, and national technology strategy, the role of directional industry strategy is then made clear. Furthermore, the six assumptions of emphasis on formulating strategy (rather than on formulating policy), emphasis on formulating directional strategy, model's prescriptivism, emphasis on formulating the strategy at the level of industry, Iran's being a developing... 

    Variable speed wind turbine power control: A comparison between multiple MPPT based methods

    , Article International Journal of Dynamics and Control ; 2021 ; 2195268X (ISSN) Nouriani, A ; Moradi, H ; Sharif University of Technology

    Abstract
    Reducing the renewable energy costs is necessary for the competition with the fossil energies and control strategies have great impact on the efficiency of wind machines. In the wind turbine industry, a practical approach is to maximize the energy capture of a wind machine by optimizing the power coefficient in the under-rated situations. In this paper, with the main objective of maximizing the energy capture in the second region, four different control strategies are compared in the presence of uncertainties. The proposed control methods are compared based on their power capture and robustness against probable uncertainties in the structural and environmental parameters. A two-mass...
