摘　　要：应用系统动力学对短生命周期产品的生产运作进行建模与仿真,并在此基础上实现优化。此类问题分析的复杂性源于系统各要素之间存在复杂的相互作用,并在较短的产品生命周期内作用更加明显。而传统的数学建模方法因难以清晰、简洁地描述出这些非线性关系而不能被应用于此类问题的研究。因此,建立了短生命周期产品生产运作的系统动力学模型,通过仿真来实现系统运行绩效的优化。模型中不仅模拟了产品有限生命周期内的需求变化,还考虑了劳动力资源对产品生产、顾客满意度对产品需求的影响等诸多现实问题。最后,通过对一个具有代表性的短生命周期产品的运作仿真,演示了在仿真数据的分析基础上对系统参数实现了优化。This paper proposes a system dynamics approach to optimize operations performance of short life cycle products. The difficulty of optimization stems from complex interactions among elements of the system, and it gets worse due to product short life cycle. System dynamics was employed to model the problem. By constructing a system dynamics model of the problem, system performances are optimized by simulation. In the model, demand pattern of short life cycle products is modeled as combination of multi- causal loops. Additionally, some practical factors such as labor resource, customer satisfaction, are also taken into consideration. A typical scenario of the system is implemented to demonstrate the advantage of simulation.
