Learn ARENA-SCRIPTING with Real Code Examples

Arena Scripting enables automation and logic customization in Arena simulation models.

Supports both SIMAN modules and embedded VBA scripts for advanced behaviors.

Used to define entity behaviors, resource scheduling, and system interactions.

Allows integration with external data sources and Excel for dynamic simulation inputs.

Facilitates creation of reusable logic blocks and custom simulation functions.

Entity and resource control using SIMAN syntax

Event scheduling and conditional logic

Custom VBA macros for model automation

Statistical collection and performance metrics scripting

Integration with external data files (CSV, Excel, Access)

Entity - item flowing through the system

Resource - object performing tasks for entities

Queue - holding place for entities waiting for resources

Module - building block of Arena model representing process logic

VBA/SIMAN Script - code controlling entity/resource behavior

Arena model (.doe file)

SIMAN script files embedded in modules

VBA macros linked for external control

Excel or database files for input/output

Output statistics modules and charts

Define entities, resources, and queues in the Arena model

Identify areas requiring custom logic or automation

Write SIMAN or VBA scripts for entity behavior and events

Attach scripts to appropriate modules in the model

Test and validate model behavior with simulation runs

Beginner: simple routing logic and basic resource allocation

Intermediate: conditional logic and dynamic entity attributes

Advanced: multi-module reusable scripts and complex scheduling

Expert: integrating external data and automating scenarios

Architect: enterprise-scale simulation with multiple interdependent models

SIMAN vs VBA - SIMAN for internal entity logic, VBA for external automation

Arena scripting vs Python/Matlab - Arena-specific, optimized for discrete-event models

Arena vs AnyLogic - Arena uses SIMAN modules, AnyLogic allows Java-based modeling

Manual modeling vs scripting - scripting enables dynamic, repeatable behaviors

Custom modules vs built-in modules - custom allows advanced logic and reuse
