Truthful multi-unit transportation procurement auctions for logistics e-marketplaces

► Proposed one-sided VCG (Vickrey-Clarke-Groves) combinatorial auctions for a complex transportation marketplace with multiple lanes, realizing maximal social welfare. ► Designed three truthful multi-unit trade reduction (MTR) mechanisms for the bilateral exchange transportation marketplace where all the lanes are partitioned into distinct markets. ► Developed a randomized auction mechanism to capture the trade-off between the O-VCG and MTR auction classes.
