Markdown Time for Perishables Based on Dynamic Quality Evaluation for Complex Data Analysis

Perishables’ freshness is a dynamic state, which can be captured by statistical big data based on advanced product identification and sensory technologies. A time-based markdown strategy model is proposed to consider the markdown strategy in maximizing performance. The results showed that demand uncertainty would force them to implement a markdown strategy in advance, merchants’ profit and initial inventory are sensitive to the uncertainty and deterioration rate of perishable quality, and markdown time has a regulatory effect on initial inventory.
