Abstract: Abstract Maintaining a full workforce is critical to the operational efficiency of ports, which are key to the functioning of global maritime transportation systems, as well as to the larger logistics systems and the industries they support. A shortage of skilled workers, or extended, large-scale, absenteeism at one or more ports can affect cargohandling operations, competitiveness, and even the efficiency of international trade. Through numerical experiments, we study (i) whether the effects of low-level workforce shortages can be ‘absorbed’ without loss of efficiency; (ii) the level at which shortages in a region can impact another region, or the performance of the wider maritime system. To test this, we investigate the ports used by the M2 shipping alliance of Maersk Line and Mediterranean Shipping Company. The analysis is supported by advanced mathematical modeling and algorithmic procedures. Findings include that low- and even mid-level network-wide worker shortages can be absorbed, but at a greater cost to shippers. Moreover, when a worker shortage arises in some regions of the world, the impacts in other regions can be very significant.
