Embodiment Construction

[0034] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0035] For the existing container terminal logistics operation field, due to the problems existing in the calculation method based on empirical formula and combined with the traditional container terminal operation index system, this chapter proposes a set of universal modeling and simulation suitable for the container terminal logistics operation system The output index system and detailed index algorithm. The output index is a numerical value used in the general simulation system to reflect the state of operation activities and operation goals of the container terminal logistics operation system. The difference is that there is a major breakthrough in the calculation method, which will try to restore the characteristics of the discrete event d...

Abstract

The invention discloses an output indicator system of general modeling and simulation. In the output indicators, indicators concerning time can be obtained by accumulating simulation time in calculation; and indicators concerning random variables are calculated by firstly processing randomness according to step length, and then accumulated according to the step length. The output indicator system of general modeling and simulation is applicable to general modeling and simulation of container terminal logistics operation systems, and avoids accuracy problems of traditional indicator algorithms.

Description

Technical field: [0001] The invention relates to a general modeling and simulation method for a container terminal logistics operation system, in particular to an output index system for the general modeling and simulation of the container terminal logistics operation system. Background technique: [0002] Traditionally, the evaluation indicators of port loading and unloading operations can be divided into two categories: quantity indicators and quality indicators according to their nature. [0003] Quantitative indicators are also called aggregate indicators. It reflects the quantitative requirements that should be achieved or has been achieved by port production and operation activities, and it reflects the overall scale, level or total amount of work of the phenomenon, usually expressed in absolute numbers. The main quantitative indicators in port operations include: throughput, loading and unloading natural tons, operating tons, stockpiled cargo tons per day, number of ...
