Abstract: |
Container unloading/loading at
marine container terminals (MCTs) is a key logistic
process, to which some research efforts have been addressed by using
mathematical programming models formulated in a deterministic-static
environment. Vice versa, DES models in a stochastic-dynamic environment are
well capable of representing the entire process. Hence, simulation results to
be an effective planning and control tool for decision making at all
decisional levels. Here we remark that optimal decisions in MCTs may be practically pursued by modelling
the whole MCT and focusing attention on the core logistic processes, while
representing in a simplified manner the remainder. We focus on the
operational management of the cranes deployed along the quay, during the
container unloading/loading process at a given number of vessels according to
a previously planned berth- schedule. We suggest a two-phase approach to the
quay crane deployment problem: in the first phase an IP model is used to
decide when and how many cranes must be assigned to each vessel; afterwards,
we propose a heuristics to determine which specific crane should be assigned
to a vessel. We indicate how this approach can be successfully integrated in
a DES model, already available, to support dynamic assignment of cranes to
berthed vessels. |
