Abstract
ABSTRACT Considering the diversification of dry bulk terminal types and the complexity of terminal loading and unloading operations, a modular modelling method based on discrete event system specification (DEVS) modelling theory is proposed in this paper. First, we introduced the DEVS into the dry bulk terminal and explained the ideas and main steps of the DEVS-based modular modelling method. Second, a module library and model framework library for dry bulk terminals were developed, and the DEVS expression of the modules and model framework was given. Studies have shown that the production performance of a coal export terminal is generally positively correlated with ship loading and ship arrival density. Terminal operators can improve their ability to respond to future scenarios in two ways: upgrading berth levels and improving ship berthing strategies. The case verifies that the model framework and module library are effective, and the modelling method based on DEVS is feasible.
