A simulation modelling paradigm for the optimal management of logistics in container terminals

The need for an optimal management of logistic activities in modem container terminals is well recognized. Usually, the optimal management is pursued by decomposing the container terminal system in independent sub-systems to be optimized separately. Vice versa, a less practical approach, would suggest to analyze the whole system, provided that a formal, computerized model is available. We propose a simulation modelling paradigm based on the process interaction world view for the optimal management of logistic activities in a modem container terminal. Paper's focus is on the way of representing processes, resources and jobs that compose our simulation modelling paradigm. Processes are partitioned into activities following a simple to read and easy-to-use codified schema. We show how it is possible to define rules on the modelling paradigm for the optimization of the system. Concepts and representation methodologies are applied to a real case study, where it is asked to optimize the integrated management of berthing points, handling equipments and storage spaces.
