Warehouse Simulation Software Free [repack] May 2026

Abstract Warehouse simulation software allows logistics managers, industrial engineers, and students to model material flows, test layout changes, and optimize operations without disrupting real-world systems. While commercial packages (e.g., AnyLogic, FlexSim, Simio) are powerful, they carry high licensing costs. This paper explores viable free alternatives—ranging from open-source general-purpose simulators to vendor-limited free editions and academic tools—highlighting their capabilities, limitations, and ideal use cases for warehouse modeling. 1. Introduction Modern warehouses face pressure to increase throughput, reduce travel time, and integrate automation (AGVs, AS/RS, pick-to-light). Simulation helps answer: How many pickers are needed? Where should fast-moving SKUs be stored? Will a new sorter create bottlenecks? Free simulation software lowers the entry barrier for small businesses, startups, and educational settings. warehouse simulation software free

| Software | Free version limits | Warehouse use feasibility | |----------|---------------------|----------------------------| | | Up to 50 agents; 2D only; no custom Java code | Small models (single aisle, 10–20 pickers). Good for learning. | | Simio Personal Edition | 50 objects max; no external data integration | Layout testing, basic pick-to-cart studies. | | FlexSim Free (student) | Educational watermark; 6-month renewable license | Full 3D; extensive object library (racks, AGVs, operators). Best among free for realism. | | Witness Horizon | Free for small models (download after registration) | Limited to 30 elements; includes conveyors and labor. | Where should fast-moving SKUs be stored

This code can be extended with queues, storage racks (as resources), and random arrivals. While powerful, it requires manual output analysis.
