一 | American Airlines is reporting a $545 million loss for the third quarter in contrast with the huge profits posted by its two closest rivals.American said its results were dragged down by $983 million in charges related to a new labor contract with its pilots, but United Airlines and Delta Air Lines reached similar deals with their pilots and still earned $1.1 billion each in the quarter. Labor costs at American jumped 17%, an increase of nearly $600 million, which was roughly offset by lower fuel prices than a year ago.American's revenue was roughly flat with last summer, compared with 12% and 11% increases at United and Delta.There are already concerns over rising costs for airlines as fuel prices surge at the same time that travel has begun to slow. Fuel prices are still lower than they were last year, but the loss at American could add to anxiety over burdensome costs across the industry. Citing rising fuel prices on Wednesday, United Airlines gave a surprisingly weak end-of-year forecast after a solid third quarter, sending shares major carriers lower. United also noted the suspension of its flights to Tel Aviv because of the Israel-Hamas war.American Airlines Group Inc., based in Fort Worth, Texas, said its earnings excluding special items worked out to 38 cents per share. Analysts expected 25 cents per share, according to a FactSet survey.Revenue of $13.48 billion was slightly below Wall Street forecasts.American, which took on new debt during the pandemic, said it paid down $1.4 billion in debt during the quarter.Shares of American rose about 2% before the opening bell. Company executives will discuss the results with analysts and reporters later Thursday.。 8月12日9时许，河钢集团唐钢公司生产调度中心，18米宽的大屏幕上，钢铁生产十几道工序的4000多个关键节点数据实时跃动。电脑前，生产制造部计划员轻点鼠标，一份由人工智能大模型生成的生产计划便下发至各个部门。生产排程是决定钢铁生产效率的核心环节。以往，唐钢公司生产排程完全依赖计划员的经验，不仅效率低，还存在工序衔接不畅导致库存积压、交付延期的风险。“现在不同了！‘最强大脑’围绕订单交付时间自动规划最优流程，能够确保按期交付。”唐钢公司信息自动化部信息化管理师赵维娜介绍。
8月12日，河钢集团唐钢公司生产调度中心，工作人员正在查看生产数据。
二 | 日报记者 师 源摄赵维娜口中的“最强大脑”，是唐钢公司自主开发的APS（高级计划与排程）系统。
三 | 它依托人工智能大模型等前沿技术，可快速解析数据，精准找出生产排程最优解。
四 | “过去，一个热轧钢卷订单从接单到交付需要18天。APS系统投用后只要12天。”赵维娜说，这让计划员们从庞杂的数据中解放出来，将工作重心转向订单追踪和库存管理，使生产流程更顺畅、资源利用更充分。数据显示，自APS系统应用以来，唐钢公司高强汽车板有限公司冷轧产线产品库存降低15%，生产效率提升20%，订单准时交付率达到100%，公司核心竞争力显著增强。
五 | 唐钢公司与人工智能大模型双向奔赴，正在擦出更多火花。10时许，唐钢公司炼钢事业部转炉作业平台，转炉内的钢水发出耀眼光芒，出钢作业正在进行。一墙之隔的转炉主控室内，炼钢助手田猛紧盯智能大屏，手指轻轻按动出钢按键，转炉开始缓缓倾动。“过去是在炉前手动摇炉，非常考验操作功底，稍有偏差就可能造成事故。”田猛说，现在依托“全过程一键炼钢智能体”系统，一键即可完成摇炉作业。不仅如此，“一键炼钢”大模型还可以自动加料、自动吹炼、自动吹氩等，实现了钢铁生产全过程一键式操作，极大改善了工作环境，既降低了工作强度，又提高了生产效率。有了“一键炼钢”大模型，唐钢公司转炉生产效率提升8.8%，吨钢煤气回收率提升近16.3%，钢水纯净度跃升至行业第一梯队，带动了产品结构优化升级。
六 | 如今，管线钢、电池壳钢、高强度汽车钢等成为公司的拳头产品。随着大模型技术的不断应用，唐钢公司正加速“智”变。目前，公司90%以上工艺场景实现模型化、数字化应用，吨钢综合能耗降至511.42千克标准煤，达到同行业先进水平。
七 | “下一步，我们将持续深化人工智能与工业场景的融合，推动更多专业模型落地应用，打造覆盖采购、生产、物流、服务等环节的全链条智能生态体系。
