Based On The Theory Of Ie Cutter-suction Dredger Operation Optimization Research

The article is based on a large lean production optimization project. Before the project, the operations of the self-propelled trailing suction hopper dredgers is in chaos, in order to change the situation, making more scientific operating standards, we use the relevant theories of industrial engineering and management, statistics of relevant knowledge, the existing knowledge experience, the data mining method, the wide application of industrial engineering analysis tools, the existing dredging operations reviews and optimization method, formed a dredging operations for the optimization of the standard. It is the first optimization standard of the type of ship.First, the paper introduces the background and the significance of the research, and then introduces the dredging industry, wring self-propelled trailing suction hopper dredgers. Move transversely process is ground for production process of self-propelled trailing suction hopper dredgers, belong to the process of creating value, according to the characteristics of process operation, we apply sampling statistics method and benchmarking management thoughts from main operation parameters of scope, driving for dredging operation parameters set standards. The move transversely process is ground work self-propelled trailing suction hopper dredgers auxiliary process, itself does not produce value, so reduce these processes operating time is the key process optimization, therefore, we first use time measurement technology on the move transversely process, and make the statistical analysis, gives a scientific operation time; further to make a scientific and rational operation method, based on the experience in mining, we use of industrial engineering tools and ECRS thought and the flow chart of benchmarking management thinking of the excellent operation decomposition, from operating levels in time study of the operation of the variables on program thinning analysis, and after heavy combination, get more optimized operation method, for every the move transversely working procedure established a scientific, economic operation standard.
