[Abstract]:With the development of high load, high efficiency and automation in the professional bulk cargo terminal, the reliability of the loading and unloading system is increasingly prominent. The modern bulk cargo terminal loading and unloading system is a complex logistics system, with many kinds of machinery and equipment, a large number of equipment, the randomness of equipment failure, the uncertainty of maintenance time, and the connection of equipment. In the guidance of the system reliability theory, the discrete event dynamic system theory and the system simulation technology, the reliability of the new type silo coal wharf loading and unloading system is studied in this paper. The main contents are as follows:
(1) based on the system reliability theory, the reliability of the loading and unloading system of the dry bulk terminal is deeply studied. From the subdivision function of the loading and unloading system, the meaning of the reliability of the loading and unloading system of the bulk cargo wharf is described and analyzed more deeply. Based on the reliability index of the single machine equipment and the combination of the loading and unloading process lines, the loading and unloading system is drawn out. Two new system reliability indices, basic reliability and fine reliability, have enriched the reliability theory of port handling system.
(2) according to the widely collected data of the failure of the loading and unloading equipment of the coal wharf, the reliability index of the main type loading and unloading equipment is summed up, and the basic reliability of the loading and unloading line of the wharf and the out of the storehouse is calculated and analyzed. Based on the theory of discrete event dynamic system, a new type of silo loading and unloading system for a new silo is designed and designed. The idea of reliability simulation for loading and unloading system of dry bulk cargo terminal is put forward, and a detailed reliability simulation research model for loading and unloading system of silo coal terminal is established.
(3) based on the reliability simulation model of the loading and unloading system of the silo coal wharf, the simulation test is carried out by changing the fault factor and the repair factor, and the system reliability parameters are obtained under the different fault level and the repair level. On the basis of the simulation test data, the method of estimating the incoming / out of the warehouse of the silo coal wharf is proposed, respectively. The loading and unloading capacity of the dump and out of the storehouse is calculated. The theory of the loading and unloading system of the Wharf under certain reliability conditions can reach the throughput, which provides the data support for the evaluation of the capacity of the loading and unloading system of the wharf.
The research results of this paper will provide useful support and support for future planning and design of the handling system of dry bulk cargo terminals and the management of wharf equipment.
