需求预测(Demand Forecasting)是指通过分析历史数据、市场趋势和外部变量,系统性地预估未来某一时期产品或服务需求量的过程。其核心目标是帮助企业优化资源配置、减少库存成本并制定科学的生产计划。
从方法论来看,需求预测主要包含三类技术路径:
在实践应用中,沃尔玛通过需求预测系统实现了98.3%的库存周转准确率,该系统整合了天气数据、社交媒体舆情等300+变量(哈佛商业评论案例库)。制造业领域,丰田汽车的JIT(准时制生产)体系每年节省超2.6亿美元仓储成本,其底层逻辑正是精准的需求预测(MIT斯隆管理学院运营分析报告)。
Demand forecasting(需求预测)是指通过分析历史数据、市场趋势和其他相关因素,对未来一段时间内产品或服务需求量的预估过程。它是企业运营和战略规划的核心工具,广泛应用于供应链管理、库存控制、生产计划等领域。
目的
帮助企业提前预判市场需求,优化资源分配(如原材料采购、人力资源安排),减少库存积压或短缺风险,提升客户满意度。
主要方法
应用场景
挑战与局限
简单移动平均法的公式为:
$$
Ft = frac{D{t-1} + D{t-2} + dots + D{t-n}}{n}
$$
其中,( F_t )是第( t )期的预测值,( D )为历史实际需求,( n )为周期数。
有效的需求预测可降低运营成本约10-30%(部分研究数据),尤其在全球化供应链中,精准预测能显著增强企业抗风险能力。
