The presented paper comes as a summary of a theoretical work presenting an original algorithm describing International Multimodal Transport (IMT) mechanisms and processes. Since containers appeared in early 1960s on the regional, and later on, on global scale in logistic operations, the IMT has become the fastest growing combination of an international through-transport. With use of various modes of transport IMT has significant influence on global trade development. Due to its characteristic the IMT process is exposed on the global unitization, standardization, safety, security and economization (optimization) challenges. Thus, there is a need for scientific approach in building a standardized conceptual model of IMT referred in this paper to CAIMT. CAIMT is an original, deterministic algorithm, presented in the block notation, identifying typical procedures as a logical continuation of the programmed sequence of the basic IMT operations. The suggested CAIMT has a potential in further standardization of IMT procedures and can be scientifically developed through the modeling of the IMT processes and safety/security procedures. In addition, in terms of empirical aspects, algorithmization of the main IMT processes can lead to their application in the various expert systems. Summing up, this method (CAIMT) comes as an optimal instrument that can be utilized in order to build further pillars for IMT development, standardization and optimization.
