In this study, a two phase hybrid heuristic approach was proposed to solve the multi-depot multi-vehicle inventory routing problem (MDMVIRP). Inventory routing problem (IRP) is one of the major issues in the supply chain networks that arise in the context of vendor managed systems (VMI) The MDMVIRP combines inventory management and routing decision. We are given on input a fleet of homogeneous ...

This pilot study investigates how considering accessibility could help to model prices of residential real estate more accurately. We introduce two novelties from the price modeling point of view (1) defining accessibility as travel time by public transport, in addition to geographic distance, and (2) considering dynamic points of interest from check-ins into social networks, in addition to fix...
