Wireless rechargeable sensor network (WRSN) uses mobile chargers (MCs) to charge nodes wirelessly solve the energy problems faced by traditional wireless network. In WRSN, charging schemes with multiple MCs supplementing are quite common. How properly plan MC’s moving path reduce loss and deploy improve coverage rate has become a huge research challenge. this paper, collaborative optimization a...

Multidisciplinary optimization (MDO) is concerned with complex systems exhibiting challenges in terms of organization and scale. Thus, it is well suited to be applied to complex multivariable control design. Collaborative optimization is one approach for dealing with complex multidisciplinary optimization problems. Three MDO architectures, including collaborative optimization, are applied to co...

Due to diversified and frequently changing demands from customers, technological advances and global competition, manufacturers rely on collaboration with their business partners to share costs, risks and expertise. How to take advantage of advancement of technologies to effectively support operations and create competitive advantage is critical for manufacturers to survive. To respond to these...

This paper proposes a robust model for optimizing collaborative reverse supply chains. The primary idea is to develop a collaborative framework that can achieve the best solutions in the uncertain environment. Firstly, we model the exact problem in the form of a mixed integer nonlinear programming. To regard uncertainty, the robust optimization is employed that searches for an optimum answer wi...

introduction: collaborative testing is a learning strategy that provides students with the opportunity to learn and practice collaboration. this study aimed to determine the effect of collaborative testing on test performance and retention of course content in nursing students of shiraz university of medical sciences, shiraz, iran. methods: this quasi-experimental study was carried out on 84 st...

In recent years, the combination of cognitive radio and collaborative communication has been widely studied applied because its ability to increase user throughput improve spectrum utilization in a flat-fading wireless channel environment. Such networks that use collaboration capacity are called networks. A Nash equilibrium game-based relay node selection algorithm is investigated, which aims m...
