Leonardo J. Basso et al., Analytics Saves Lives During the COVID-19 Crisis in Chile, INFORMS Journal on Applied Analytics, 2023, 53(1):9-31. (2022 Franz Edelman Award) (statistical analysis, integer programming, regression)
During the COVID-19 crisis, the Chilean Ministry of Health and the Ministry of Sciences, Technology, Knowledge and Innovation partnered with the Instituto Sistemas Complejos de Ingeniería (ISCI) and the telecommunications company ENTEL, to develop innovative methodologies and tools that placed operations research (OR) and analytics at the forefront of the battle against the pandemic. These innovations have been used in key decision aspects that helped shape a comprehensive strategy against the virus, including tools that (1) provided data on the actual effects of lockdowns in different municipalities and over time; (2) helped allocate limited intensive care unit (ICU) capacity; (3) significantly increased the testing capacity and provided on-the-ground strategies for active screening of asymptomatic cases; and (4) implemented a nationwide serology surveillance program that significantly influenced Chile’s decisions regarding vaccine booster doses and that also provided information of global relevance. Significant challenges during the execution of the project included the coordination of large teams of engineers, data scientists, and healthcare professionals in the field; the effective communication of information to the population; and the handling and use of sensitive data. The initiatives generated significant press coverage and, by providing scientific evidence supporting the decision making behind the Chilean strategy to address the pandemic, they helped provide transparency and objectivity to decision makers and the general population. According to highly conservative estimates, the number of lives saved by all the initiatives combined is close to 3,000, equivalent to more than 5% of the total death toll in Chile associated with the pandemic until January 2022. The saved resources associated with testing, ICU beds, and working days amount to more than 300 million USD.

2023 Edelman Competition (video)
Prakhar Mehrotra et al., (2024) Optimizing Walmart’s Supply Chain from Strategy to Execution. INFORMS Journal on Applied Analytics 54(1):5-19.

花 441 元坐自強號，竟然比 284 元的復興號慢，這又貴又慢的自強號，讓乘客坐得好悶，點進去龜速的 224 次自強號查看，從樹林到花蓮，數一數，竟然狂停了 19 站，684 次的復興號開到台東，也不過才停 10 站。
北花自強號除了「跑輸」復興號，同樣是自強號，快慢也差很多。最快的太魯閣號只須兩小時，最慢的竟要三小時十三分。台鐵解釋，六八四、六八五次主要是為疏解北東自強號的需求，才會推出停站少、便宜票價的復興號吸引旅客；上午七時卅分從台北出發的二七二次自強號，沿途有很高的通勤需求，加上同時段替代性列車少，才會停站較多。台鐵說，北花自強號平均約兩小時四十分，「並沒有真的差很多」。
Until 1995, Netherlands Railways (Nederlandse Spoorwegen, or NS) was a state-owned company, operating passenger and freight services and building and maintaining the railway infrastructure. Because of European Union regulations and liberalization of the railway market, NS was split into several companies during the period 1995–2002. The state maintains ownership of the infrastructure because of its strategic value. ProRail, a nonprofit organization owned by the state, is responsible for maintaining and allocating the infrastructure. Several companies, including NS, now operate the passenger services; there are also a number of freight operators.
The new resource schedules and the increased number of passengers resulted in an additional annual profit of E40 million ($60 million); the additional revenues generated approximately E10 million of this profit. We expect this profit to increase to E70 million ($105 million) annually in the coming years.

首先，在計算組員派遣的合法性時，有兩個專用詞：「飛時」以及「工時」。
「飛時」在直觀上也許會認為是飛機在空中飛行的時間，其實不然。為了嚴謹的計算，飛時的計算方法是航機在登機門完成登機及貨物裝載後，機門關閉，開始由拖車後推的那個時間點起算（飛航電腦會感測並自動記錄顯示此時間點），直到航機落地後滑行到登機門位置開艙門當下的時間點為止。工會訴求的八小時及十二小時指的就是這個「飛時」。
