Abstract: With the methodology of modeling and optimization for container terminal logistics systems based on Harvard architecture,the framework and mechanism of task scheduling and resource allocation in Container Terminal Operation Systems(CTOS)were discussed,and a CTOS computational model was proposed.On the fundamental principles of generalized computer integrated manufacturing systems,CTOS control decision was treated as collaborative computing between multiple control processes.Based on the design concept of computer Operating System(OS),the  conceptual perspective of CTOS was obtained.By integrating the design ideas of OS such as delamination,microkernel,exokernel,virtual machine and client/server computation,the computational model for CTOS was given,and the corresponding control decision framework and paradigm were presented.The production operation case of typical container terminal was taken as an example to self-define the multiple scheduling strategies,and the container terminal logistics service performance was evaluated and analyzed according to the task latency,throughout,load balancing and so on.The feasibility and creditability of proposed model was validated effectively.
