Inspired by successful cross-docking applications in the prevailing supply chain management (SCM) business such as Wal-Mart, Fed Ex, and Home Depot, we propose a new collaborative vehicle routing and scheduling model with cross-dock under uncertainty. Conventional cross-docking models treat the vehicle routing and docking scheduling components as(More)
The stable mononuclear Ni(III)-thiolate complexes [NiIII(L)(P(C6H3-3-SiMe3-2-S)3)]- (L = SePh (2), Cl (3), SEt (4), 2-S-C4H3S (5), CH2CN (7)) were isolated and characterized by UV-vis, EPR, IR, SQUID, CV, 1H NMR, and single-crystal X-ray diffraction. The increased basicity (electronic density) of the nickel center of complexes(More)
