为提高输入缓冲设置的科学性与合理性,在计算输入缓冲时,需考虑非瓶颈紧前工序的分布并区分瓶颈工序风险和非瓶颈工序风险的大小。文章运用模糊理论方法,考虑工序的位置权数、资源紧张度、工序复杂度以及风险承受度因素,计算非瓶颈紧前工序的工序缓冲;根据非瓶颈紧前工序的工序缓冲及其分布推导输入缓冲的计算公式;并通过算例验证方法的合理性。文章的结论是风险承受度及非瓶颈紧前工序分布对输入缓冲具有重大影响,且后者的影响大于前者。

To improve the scientificness and rationality of feeding buffer settings,in calculating the capacity of the feeding buffers,the distribution of non-bottleneck immediate predecessor operations should be considered. Also,the degree of bottleneck non-bottleneck operation risk should be distinguished. By using fuzzy theory,the buffering requirement of non-bottleneck immediate predecessor operations is calculated by considering some factors,such as process location weight,the degree of resource tensity,process complexity,and risk tolerance. Based on the buffer configuration and distribution of non-bottleneck immediate predecessor operations,a formula for calculating the capacity of a feeding buffer is deduced. The reasonableness of the proposed method is verified by an example. Result shows that the distribution of non-bottleneck immediate predecessor operations and risk tolerance have a significant influence on the capacity of a feeding buffer,and the latter is greater than the former.
