摘要:

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。

关键词: BOM, 时间约束网络, 模糊时间, 生产计划

Abstract:

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.

Key words: bill of material(BOM), time constraint network, fuzzy time, production schedule
