针对广义 BOM 建模中的时间模糊性和约束多样性问题，提出了 BOM 时间的多色图描述方法。采用模糊数表达 BOM 时间，通过图的“着色”实现多种时间约束的表达；建立了 BOM 时间到时间约束网络的映射规则，给出了 BOM 时间一致性的判定和求解方法；最后通过实例对 BOM 时间模型及其求解方法进行了验证。

A polygraph based method was proposed to describe time constraints and fuzzy time in one BOM.The time attributes was represented with fuzzy number and pigmentation of polychromatic set.Rules and approach were put forward to check and calculate the time consistency from BOM to time network.A case study was illustrated for evaluating the proposed method.
