The problem of multi-unit multiattribute trading, though useful in practical procurement settings, has been rarely addressed in auction literature. We present a general framework to structure specifications of preferences over multi-unit multiattribute outcomes, allowing flexible tradeoffs between expressiveness and compactness of representation. Next, we use this framework to propose an auctio...

this paper explores the capabilities of multi-objective particle swarm optimization algorithmin a simulation-optimization model for solving waste load allocation problems. the main goals are totaltreatment costs, violation of the water quality standards and equity. in this research, the water qualitysimulation model is coupled with a multi-objective optimization model, mopso. in order to derive...

Economic and technical features are equally important to radio resource allocation in wireless network virtualization (WNV). Regarding virtual resource (VR) as commodity, this paper proposes an effective VR allocation scheme for WNV from the perspective of the marketequilibrium theory. First, physical meaning clear utility functions are defined to characterize the network benefits of user equip...
