In this paper, a new multi-objective technique has been proposed for optimal analysis of three different candidate heat pump solutions including the vapor compression cycle (VCC), trans-critical R744 cycle, and Peltier device to determine which one gives the best configuration and better...

Puzzle-based storage systems (PBSs) can achieve very high utilization of expensive and scarce storage space coupled with fully automated storage and retrieval of unit loads. A PBS system with one empty cell is comparable to the well-known 15-puzzle, in which 15 tiles slide in a 4×4 grid. This...
