    Criterios A.S.G. en Colombia
    (Universidad EAFIT, 2023) Vásquez Sánchez, Daniela; Pineda López, Juliana Andrea; Toro Valencia, José Alberto; Araujo Henao, Melisa
    The E.S.G. criteria are a set of practices mostly used in the corporate and financial guild, they promote responsible and sustainable decision making in environmental, social and corporate governance areas; the development of these criteria comes from the international arena, where different organizations, during the last years, have made a call to the nations to take measures against the lack of responsibility in terms of sustainability of today's society. Therefore, different reports, declarations, agreements and treaties have been made where different nations are committed to sustainability; for this reason, the importance of corporations for the achievement of these objectives should be highlighted, this has been evidenced in the intention to link companies in different ways both internationally and transnationally.

    Maintenance policy optimisation for multi-component systems considering degradation of components and imperfect maintenance actions
    (Elsevier Ltd, 2018-10-01) Martinod R, R.M.; Bistorin, Oliver; Castaneda Heredia Leonel F.; Rezg, Nidhal; Universidad EAFIT. Departamento de Ingeniería Mecánica; Estudios en Mantenimiento (GEMI)
    This article proposes a stochastic optimisation model in order to reduce the long-term total maintenance cost of complex systems. The proposed work is based on the following approaches: (i) optimisation of a cost model for complex multi-component systems consisting of preventive and corrective maintenance using reliability analysis, which faces two different maintenance policies (periodic block-type and age-based) and (ii) a clustering method for maintenance actions to decrease the total maintenance cost of the complex system. This work evaluates each maintenance policy and measures the effects on imperfect maintenance actions. Finally, the proposed optimisation model is applied to a numerical example which focuses on passenger urban aerial ropeway transport systems, in which the current maintenance policy has been evaluated, considering the established by the international regulation of passenger aerial cable cars. © 2018 Elsevier Ltd
