We implement a decision support model (DSM), which leads to realistic export opportunities. We also develop a heuristic DSM for the combinatorial optimization problem. We use trade data in the four-digit SITC for the Southern Euro Area (EA) countries. We find that Italy, followed by Spain and Portugal, has the highest potential to expand exports. We identify realistic export markets for the Southern EA countries, mainly in Europe, East Asia and the Pacific, and the Middle East. The sectors with the highest prospect for exports are Manufactured goods for all Southern EA countries, followed by Machinery and transport equipment for Italy, Spain, and Portugal, and Food and live animals for Greece.

我们实施决策支持模型 (DSM)，从而带来切合实际的出口机会。我们还为组合优化问题开发了启发式 DSM。我们使用南欧元区 (EA) 国家的四位数 SITC 贸易数据。我们发现意大利，其次是西班牙和葡萄牙，扩大出口的潜力最大。我们为南欧国家确定了现实的出口市场，主要是欧洲、东亚和太平洋地区以及中东。出口前景最高的部门是所有南欧国家的制成品，其次是意大利、西班牙和葡萄牙的机械和运输设备，以及希腊的食品和活动物。
