Loading/unloading vessel production model in container terminal operation system

Abstract

The invention discloses a loading / unloading vessel production model in container terminal operation system, the model comprises: firstly checking whether the arrival absolute time of the future arrival vessel is less than or equal to the time of a simulation clock, if so, a vessel should be arrived in the step length; checking the berth state in the step length, and distributing various machines according to the based on machine distribution principle according to the berth and the stopped vessel; then entering the apron operation, horizontal transfer operation and storage yard operation of loading / unloading bridge sequentially, taking the minimal processing quantity in a step length in a service staff set composed of three serial machines as the actual processing quantity of loading / unloading vessel operation, and corresponding adjusting the actual operation time of various machines. The invention is realized by above technical solution, the implementing steps are simple, and the whole modeling is simply and easily realized; and simultaneously, the realized model is suitable for modeling and simulation of generality of container terminal logistics operation system.

Description

Technical field: [0001] The invention relates to a modeling method of a universal simulation system for logistics operation of a container terminal, in particular to a modeling method of a loading and unloading ship production model in the container terminal operation system. Background technique: [0002] Simulation is a model-based activity, and system simulation is to build a system model and conduct experiments on the model. The application of modeling and simulation technology in the port terminal system is deepened along with the development of the simulation technology itself and the improvement of the mechanization and automation level of the port terminal. Looking at domestic and foreign literature, foreign academic circles began to gradually heat up the research on container terminal modeling and simulation since the late 1990s. Compared with foreign countries, domestic research on the simulation and modeling of container logistics systems is still in its infancy,...

Problems solved by technology

[0006] (2) The modeling and simulation system is only applicable to one port object, which is not conducive to using the simulation system to accumulate experience and seek laws

In this context, each modeling can only be applied to one object, not only the response to the demand is slow, but also it is not conducive to the use of the simulation system to accumulate experience and seek laws

[0008] (3) It is difficult to use non-port-specific simulation software to model simulations that can hardly cover all management and operation links of the port

[0009] Since the modeling methods of these special-purpose simulation languages ​​(such as Flexsim, etc.) are given in the software, and because the software is non-port-specific simulation software, it is generally applicable to a variety of systems, but it cannot cover all the management and operations of the port. link simulation

Therefore, its modeling rules are narrower than those of the container terminal logistics operation system and do not fully match

The use of these software modeling and simulation is suitable for the research of a single or segmented link of the container terminal, but when it comes to the simulation of the logistics system of the container terminal that requires holistic research, it often shows the characteristics of being too small to fit the shoe
