Heterogeneity in decentralized asset markets

Julien Hugonnier

We study a canonical model of decentralized exchange for a durable good or asset, where agents are assumed to have time-varying, heterogeneous utility types. Whereas the existing literature has focused on the special case of two types, we allow agents' uti ...

A dynamic scheduling tool and a methodology for creating digital twin of manufacturing systems for achieving Zero Defect Manufacturing

Foivos Psarommatis Giannakopoulos

Nowadays manufacturing environment is highly volatile and rapidly changing as the need of products is increasing exponentially, due to the fact that Product Life Cycle is shortened and therefore more products are required to be manufactured or remanufactur ...
