We investigate the problem of minimising power consumption in dense Wireless Local Area Networks (WLANs), by optimally establishing the association of User Terminals (UTs) to Access Points (APs). This management allows to switch off some APs, granting important power savings, while at the same time guaranteeing to satisfy the data rate requirements of all UTs. The considered WLAN power minimization...
In Home Care optimization, operators have to be assigned to patients by taking into account compatibility skill constraints, and patient visits have to be scheduled in a given planning horizon. Moreover, operator tours have to be determined. Integer Linear Programming models have been proposed which use the concept of patterns, i.e. a priori scheduling profiles, to combine the diverse decision levels...
