The Study On Coal Yard Operation Flow Optimization

This paper focus on port coal yard operation flow, optimizes the special coal yardoperation system of JingTang port, aims to explore the method of improving port coalyard operation system efficiency. According to the characteristics of the subject, systemanalysis, qualitative analysis and quantitative analysis method are adopted.First, this paper proposes the research background and significance of the subject,analyzes and summarizes the present research situation and significance of port yardoptimization from two aspects, which are port yard operation optimization and simulationoptimization. Domestic and foreign scholars mostly concentrate on the optimization ofport container terminal logistics system and container yard operation management,studies on optimization of coal port yard is relatively less. Then research content andresearch methods are put forward.Second, this paper introduces the related theory of port coal logistics, the basiccomponents of coal terminal, the process of coal terminal production handling andscheduling principle, Then introduces the basic theory of discrete event systemssimulation modeling, the system simulation software witness and its superiority, theseprovide theory support for yard operation system modeling and simulation in this paper.Once again, this paper analyzes the coal yard operation flow and presentmanagement situation of JingTang port, proposes main problems existing in the yardoperation flow, establishes mathematical optimization model for unloading operations,shipment assignments and yard reclaimer homework. Then defines yard operation systemsimulation element, sets element visualization and detailed definition logical, establishessimulation model according to the steps of witness simulation modeling.Finally, this paper sets model initialization parameter according to the actual coalyard operation data of JingTang port, operates simulation model many times and recordsthe experimental results, analyzes the variation of several key indexes including themechanical equipment utilization of yard system, the stock of yard coal pile and turnover rate and so on. Then puts forward implement recommendations for the coal yardoperation optimization of JingTang port based on the experimental analysis report, whichprovide reference for future port management.
