ABSTRACT

This paper addresses the pricing policies of substitutable fresh food products under different market structures. By considering the quality changes of fresh products over time, these paper models a situation wherein substitutable fresh products are sold and the seller makes decisions regarding the times to markdown prices and offer discount rates. Furthermore, the standard and two-level evolution algorithms are adopted to solve numerical cases that involve different market structures. Based on the profit function of each product, the optimal solutions for different market structures – monopoly and monopolistic competition – are derived.

不同市场结构的新鲜食品企业的定价

抽象的

本文探讨了不同市场结构下可替代新鲜食品的定价政策。通过考虑新鲜产品随时间的质量变化，这些论文模拟了一种情况，在这种情况下，可替代的新鲜产品被出售，而卖方则决定降价时间和提供折扣率的时间。此外，采用标准和两级演化算法来解决涉及不同市场结构的数值情况。根据每种产品的利润函数，得出针对不同市场结构（垄断和垄断竞争）的最佳解决方案。
