SupplyNetPy：面向任意供应链与库存网络高保真建模与仿真的开源 Python 库
SupplyNetPy: An Open-Source Python Library for High-Fidelity Modeling and Simulation of Arbitrary Supply Chain and Inventory Networks
AI 导读
SupplyNetPy 是一个开源 Python 库，可对任意多级结构的供应链网络进行离散事件仿真，支持多种补货策略、易腐库存、节点中断以及随机需求和提前期。用户以图结构描述供应链、由库负责仿真并输出节点与网络级性能报告，组件均可通过继承扩展。该库已通过解析基准、商业工具和已发表案例研究验证，论文被 Winter Simulation Conference 2026 接收。

Abstract:This paper introduces SupplyNetPy, an open-source, well-documented Python library for modeling and discrete-event simulation of supply chain networks with arbitrary multi-echelon structures. It supports multiple replenishment policies, perishable inventory, node disruptions, and stochastic demand and lead times. All components are extensible via inheritance. Users describe a supply chain as a graph with node and link attributes, while the library handles simulation, providing logs and extensive node and network level performance reports. This paper presents the motivation, design, key features, and architecture of SupplyNetPy, along with detailed validation results (against analytical benchmarks, a commercial tool, and a published case study). A key motivation behind SupplyNetPy's development is programmatic generation and simulation of complex models, enabling design-space exploration, what-if analysis, training data generation, and supply chain digital twins.
