“…El formalismo aportado en conceptos tales como sincronismo, concurrencia, exclusión mutua y compartición de recursos son de especial interés y han aportado una mayor capacidad y potencia de representación en los modelos resultantes. Algunas aplicaciones importantes en modelos discretos para el proceso de compras verdes o en el diagnóstico de fallos de sistemas complejos pueden verse en [80,81], respectivamente. En la Figura 7 se representan de manera circular los llamados lugares (P) en los cuales suceden las acciones, y representadas por una línea negra gruesa las transiciones (T) en las cuales se detectan las condiciones.…”

La energía solar fotovoltaica en Colombia se ha convertido en una alternativa significativa para reemplazar o complementar la generación de energía convencional, por esto es importante analizar la cadena de suministro de sistemas fotovoltaicos en el país. Actualmente no hay ningún vínculo en las etapas de los procesos logísticos de la energía solar, únicamente enlaces aislados que dificultan su expansión. De acuerdo con lo anterior, en este artículo se realiza un análisis de la cadena de suministro de sistemas fotovoltaicos en Colombia a nivel general, especialmente en zonas no interconectadas. Por otra parte, se tiene como objetivo contemplar la estrategia de orientación de la cadena de suministro como primer paso para madurar un modelo que permita potenciar todas las etapas de la cadena de suministro de este tipo de sistemas en Colombia. En este caso, se utiliza una red de Petri como herramienta para su representación matemática.

Currently, developed countries have been implementing sustainable development policies specifically in Sustainable Consumption and Production (SCP). Therefore, companies consider the products and services life cycle, where Green Procurement (GP) represents a key tool for sustainability in the Supply Chain (SC). Moreover, the future on green policies in countries like Colombia has a long way to go on issues such as energy production, consumption and processes within the supply chain. In the GP area, there are three relevant issues in sustainable development policies in Colombia: 1) issues linked to barriers in the implementation such as tariffs, taxes, incentives and promotion; 2) motivation and drivers for the implementation for both public and private sector and 3) performance impacts related to the models used in order to implement in companies. The latter one is the main interest of this paper. Regarding this work, it identifies the mathematical models most widely used in SC processes, especially the issues associated with purchase processes, selection and hiring of suppliers in large and medium-sized enterprises; public or private. Moreover, the paper analyzes the models regarding their advantages and disadvantages on which some of these can be used in GP processes due its high impact. Finally, a possible mathematical model used in GP processes based on petri nets (PN) for to their characteristics and application in complex systems.

In order to determine the best maintenance time of wind turbines and identify the fault type when it is the best time to do the diagnosis work immediately. The establishment of 4-level safety status model for critical parts of wind turbines, based on wind turbine parts’ significance level, was proposed. According to the corresponding safety level of the wind turbines in real-time working status, you can decide whether the wind turbine needs diagnosis at the time or not. Therefore, we should take measures to monitor the real-time working conditions of the wind turbine’s critical parts, confirming whether the critical part need the fault diagnosis analysis or not according to its real-time working safety status. If it is the right time, then the corresponding fault diagnosis process will be initiated, through which the real online fault diagnosis can be achieved. The multi-scale wavelet decomposition and Hilbert transformation was employed to get the useful parameters such as amplitude, effective value, mean value, kurtosis value and so on of the corresponding waveform to confirm the concrete diagnosis type.
