recovery of used products is receiving much attention recently due to growing environmental concerns.in this paper, we address the carbon footprint basedon problem arising in closed-loop supply chain where returned products are collected from customers. these returned products can either be disposed or be remanufactured to be sold as new ones again. here, we formulate a comprehensive closed-loo...

This work aims at contributing to a new Sustainable Project Management (SPM) paradigm, focusing on the role of project managers as key element. The contribution this research has both practical and theoretical implications. It presents first results developed under Erasmus+ program Think Twice, recommending set ecological practices motivate develop managers’ skills adopt Management. Subsequentl...

Undesirable Output such as pollution and waste may occasionally occur in the production process, which should be reduced to improve efficiency. In the present study, cost efficiency model is presented in the presence of undesirable output by Inverse Linear Programming, and the desirable cost is calculated in order to achieve cost efficiency for units that are technically efficient but not cost-...

Purpose: Today, without having competent and efficient human resources, organizations will not be able to create transformation, development and excellence, achieve a strategic model and achieve the set goals. The way to achieve this is to develop the management and leadership of the organization and create an efficient structure for the human resources organization. Therefore, the main purpose...

One of the main capabilities grid-forming converters is ability to operate in both islanded and grid-connected modes. The work autonomously behave as an AC voltage source when they are isolated from bulk power system. In a mode, it necessary for them offer set enhancing system inertia strength. A converter may experience significant fluctuations voltage, current, frequency transition occurs. Th...

 Abstract:The purpose of this paper is to present a new model of non-radial data envelopment analysis that is able to evaluate the systems one of these complete networks is supply chain of cement industry. In this paper, using a non-radial model in data envelopment analysis, a model with a network structure that can assess the sustainable supply chain of strategic industries is evaluated....
