【摘要】 利用系统动力学的原理和建模方法描述了企业生产能力与企业物流、信息流与资金流所涉及的各种计划、生产、采购、仓储、销售及财务等职能的关系,利用因果环路图研究分析了生产能力与库存水平、交货期、市场份额、产品价格、成本、利润率、人力等多种因素的因果反馈关系,并构建了生产能力扩大的系统动力学模型来刻画其变化的复杂性与动态性。在两种市场需求(阶跃需求和泊松流随机需求)下模型的仿真结果表明,该模型能较好的反应生产能力扩大的动态行为。更多还原

【Abstract】 Based on the descriptions of the relations between plant capacity and logistics,finance and information in an enterprise,the causal loop diagram was constructed to depict the causal feedback relations between the plant capacity and stock level,lead time,market share,product price,cost,profit margin,workforce and etc..The system dynamic model of plant capacity enlargement was proposed by virtue of the method of system dynamics.The simulation results under the step demand and the demand of Poisson distribution show that the model is perfectly able to simulate the dynamic behavior patterns of plant capacity changes.更多还原
