// 动态定价算法示例
function calculateDynamicPrice(basePrice, inventoryLevel, demandTrend, competitorPrice) {
  let priceMultiplier = 1.0;
  
  // 库存水平影响
  if (inventoryLevel < 10) {
    priceMultiplier *= 1.15; // 低库存加价15%
  } else if (inventoryLevel > 100) {
    priceMultiplier *= 0.95; // 高库存降价5%
  }
  
  // 需求趋势影响
  if (demandTrend > 0.2) {
    priceMultiplier *= 1.1; // 需求旺盛加价10%
  } else if (demandTrend < -0.1) {
    priceMultiplier *= 0.9; // 需求下降降价10%
  }
  
  // 竞争对手价格影响
  const finalPrice = basePrice * priceMultiplier;
  return Math.min(finalPrice, competitorPrice * 1.05); // 不超过竞争对手价格的5%
}

// 仓储货位优化算法

        var sortedProducts = products
            .OrderByDescending(p => p.SalesFrequency)
            .ThenBy(p => p.Size);
        
        var allocation = new Dictionary();
        var availableLocations = layout.GetAccessibleLocations();
        
        int locationIndex = 0;
        foreach (var product in sortedProducts)
        {
            if (locationIndex >= availableLocations.Count)
                break;
