Abstract

The invention provides an SIMSCRIPT language-oriented discrete event simulation event queue visualization method, which comprises the following steps of: opening a simulation program, and setting interface configuration parameters by using an interface configuration module; establishing an SSH session by using a query control module to start running a program; starting an SIMDEBUG tool, and querying an event list by using a query control module; acquiring all event types by using a data analysis module; sequentially obtaining list information of each event type; drawing an event list by usinga visualization module. According to the method, the event queue can be automatically and circularly traversed by means of an SIMDEBUG debugging tool in a debugging mode, all events in the simulationprogram event list are graphically displayed according to two dimensions of event types and occurrence time, display information is updated in a manual click real-time refreshing or timed automatic refreshing mode, and the event queue is comprehensively displayed. The method is simple to operate, visual in display effect and capable of overcoming the defect that a user needs to manually query event related information item by item in an existing event query mode.

Description

technical field [0001] The invention belongs to the technical field of discrete event simulation, and in particular relates to a visualization method for discrete event simulation event queues oriented to SIMSCRIPT language. Background technique [0002] SIMSCRIPT is a discrete event simulation language with a long history and powerful functions. The language simulation mechanism is clear, the grammar abstraction level is high, and the "entity-attribute-collection" mechanism provided is very suitable for describing the entities and association relationships in the system. At the same time, SIMSCRIPT provides different levels of programming abstraction. Modelers can use the general language programming provided by SIMSCRIPT to solve calculation problems, and they can also use the simulation-oriented programming provided by SIMSCRIPT to build simulation models. SIMSCRIPT supports two simulation strategies of event scheduling and process interaction, providing modelers with fl...
