Motivated by direct interactions with practitioners and real-world data, we study a monopoly firm selling multiple substitute products to customers characterized by their different social network degrees. Under the multinomial logit model framework, we assume that the utility a customer with a...

We consider uncapacitated and capacitated assortment problems under the paired combinatorial logit model, where the goal is to fi nd a set of products to maximize the expected revenue obtained from each customer. In the uncapacitated setting, we can offer any set of products, whereas in the...

Revenue management decisions often have both strategic and tactical components. Strategic decisions happen first and set the broad and long-term operational context in which tactical decisions are frequently and repeatedly made, often on a weekly or daily basis. We consider a joint optimization...

The bike rebalancing problem is one of the major operational challenges in the urban bike-sharing system which involves the redistribution of bikes to prevent stations from being empty or overloaded. This paper investigates a new bike rebalancing problem, which considers the collection of broken...

The ‘home-field advantage’ (HFA) postulates that litter decomposes faster in home than away soils, resulting from specialization of the local soil microbial communities to decompose the litter they most often encounter. Due to the constant inputs of fresh litter, the HFA pattern could be...

Hollow porous ceramic composite membrane is a kind of potential heat transfer material, which is accompanied by heat transfer and gas-liquid mass transfer in the osmotic dehydration process. In this work, ceramic membranes with 10 nm, 50 nm and 3 μm pore-size were used for recovering moisture...

Large-scale online platforms launch hundreds of randomized experiments (a.k.a. A/B tests) every day to iterate their operations and marketing strategies, while the combinations of these treatments are typically not exhaustively tested. It triggers an important question of both academic and...

Assortment optimization is a fundamental problem in revenue management, in which the objective usually is to select a subset of products to offer to customers in order to maximize expected revenue or profit. However, business practices often involve multiple, and potentially conflicting goals....
