Optimum design for timbers handling-carrying system in harbor (1st report, simulation models for the system)

摘要

For timbers logistics, the optimum design of the materials handling-carrying system in harbor is very important. In this system, there are some indefinite factors, including operators judgment of materials handling machine etc.. For such a system, it is difficult to analyze the dynamic behavior of the system theoretically. The purpose of this research is to construct the optimum design method for principal performances of materials handling machines and the system. As the first step, in this report, a simulation analysis method has been developed to clarify the system behavior. The judgment of a shovel loader operator is treated logically on the basis of fuzzy systems theory. And the speed of load hoisting, jib hoisting, swing and travelling can be considered.
