Application of interval decision concept latticefor quality-inventory cost
区间型决策概念格在质量—库存管理中的应用

Concept lattice is an excellent tool of knowledge discovery and data mining. This paper established an interval concept lattice and applied it into the decision for quality-inventory cost. Specifically, it defined the interval formal context, the interval formal concept and established an interval concept lattice, and in the role of homomorphism, proposed the mining method of decision rules. Furthermore, from the start of the relationship between the quality and inventory cost, showed the impact factors and the relationships among them on the visualization of the concept lattice structure and the decision rules and extracted the hidden knowledge in the model and gave the specific implementation steps. Thus, for the effective development of quality management, this paper provided the basis for decision making.
