Embodiment Construction

[0039] In order to make the purpose, content and advantages of the present invention clearer, the specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0040]This embodiment proposes a SIMSCRIPT language-oriented discrete event simulation graphical modeling method, which uses a visualization module, a rule verification module and a code generation module for graphical modeling. The visualization module is used to add entities, events, routines, and processes to the canvas by dragging and dropping, and to build the calling relationship and affiliation relationship between the entities by adding connections. Among them, entity is a part of the system, which can be divided into temporary entity and permanent entity. Temporary entity is an active part of the system and leaves the system after staying in the system for a period of time. Permanent entity is a fixed part of th...

Abstract

The invention provides an SIMSCRIPT language-oriented discrete event simulation graphical modeling method, which comprises the following steps of: adding entities, routines, events and other primitives into a canvas serving as a primitive bearing container in a dragging manner according to entity flow graphs, activity cycle graphs and other modeling technologies, and representing an interaction relationship among the entities, the routines and the events through connecting lines, according to the method, primitives can be drawn and managed in the canvases, the canvases can be divided into a plurality of canvases according to the calling relation and the hierarchical relation, all the canvases can be stored as engineering files of specific formats, and the engineering files can automatically generate SIMSCRIPT simulation codes according to mapping rules. The discrete event simulation program is built based on the SIMSCRIPT simulation language and a graphical dragging mode, the problem that SIMSCRIPT grammar and manual code writing need to be familiar with when SIMSCRIPT language modeling is adopted is solved, the modeling process can be clear and visual, model reuse is simpler, thelearning cost is lower, user groups are wider, and communication between domain experts and modeling personnel is facilitated.

Description

technical field [0001] The invention belongs to the technical field of simulation modeling, and in particular relates to a SIMSCRIPT language-oriented discrete event simulation graphical modeling method. Background technique [0002] Discrete event simulation is a method of predicting system changes according to the changes of events occurring in the system at discrete time points, and it is an important system simulation technology. At present, discrete event simulation is widely used in the development of large-scale simulation systems such as aerospace, machinery manufacturing, communication and transportation, and military combat simulation. Discrete event simulation languages ​​include not only general programming languages ​​such as C, Fortran and PASCAL, but also special-purpose simulation languages ​​such as GPSS and COMNET. [0003] SIMSCRIPT language is a kind of discrete event simulation modeling language combined with general and specialized. It provides the sys...
