针对路面修复规划，提出修复批次天际线问题，用加权约束满足方法优化坑洞与裂缝修复，覆盖93.6%收益，并联合调优最小批次长度与历史半径以平衡成本与覆盖率。
AI 中文摘要
路面管理机构必须将空间分布的病害清单转化为有界、可执行的修复批次计划：事故关键缺陷（坑洞）必须始终处理，低风险缺陷（裂缝）仅在收益证明修复成本合理时才应纳入，历史修补位置提示再退化风险但本身不触发修复。我们将此形式化为修复批次天际线问题：一个定义在链距（沿道路的距离）而非时间上的加权约束满足问题（WCSP），因此仅需单时期病害调查，且不对未来退化作任何断言。WCSP识别出143个候选灾害簇（61个硬性，82个软性），其中106个合并为最终修复计划，总计1,997.4米——占若不计成本纳入所有软性候选所需2,385.9米的83.7%。该计划覆盖了观测坑洞的100%（138/138）和观测裂缝的91.6%（404/441），捕获了完整候选集中可用总灾害收益的93.6%（542/579）。天际线前沿在此点之后显示出显著的收益递减：剩余37个被排除的软性候选仅增加6.8%的额外收益，却需增加19.4%的修复长度。我们进一步将最小批次长度$L_{\min}$和历史背景半径$\kappa$形式化为该WCSP上的联合四目标超参数搜索；在同一案例研究中，推荐配置（$L_{\min} = 14.7$米，$\kappa = 10$米）相对于未调优默认值减少了7.1%的修复队动员次数，代价是预算增加12.9%和裂缝覆盖率降低1.1个百分点。
英文摘要
Pavement agencies must translate a spatially distributed distress inventory into a bounded, actionable repair-lot plan: accident-critical defects (potholes) must always be addressed, lower-risk defects (cracks) should be included only when their benefit justifies the repair cost, and historical patch locations signal re-degradation risk without themselves triggering repair. We formalize this as a Repair Lot Skyline problem: a Weighted Constraint Satisfaction Problem (WCSP) defined over chainage (distance along the road) rather than over time, so that it requires only a single-epoch distress survey and makes no claim about future deterioration. The WCSP identifies 143 candidate hazard clusters (61 hard, 82 soft), of which 106 are merged into a final repair plan totaling 1,997.4 m---83.7% of the 2,385.9 m that would be required if every soft candidate were included regardless of cost. This plan covers 100% of observed potholes (138/138) and 91.6% of observed cracks (404/441), capturing 93.6% (542/579) of the total hazard benefit available in the full candidate set. The skyline frontier shows pronounced diminishing returns beyond this point: the remaining 37 excluded soft candidates would add only 6.8% additional benefit for a 19.4% increase in repair length. We further formalize the minimum-lot-length $L_{\min}$ and historical-context radius $κ$ as a joint, four-objective hyperparameter search over this WCSP; on the same case study, the recommended configuration ($L_{\min} = 14.7$ m, $κ= 10$ m) reduces repair-crew mobilizations by 7.1% relative to an untuned default, at the cost of a 12.9% larger budget and a 1.1-percentage-point lower crack coverage.
