Problem definition: We introduce and formalize a concept termed as conditional leadtime flexibility (CLF), which refers to the industry practice where a manufacturer requests its upstream suppliers to dynamically adjust the leadtimes. We consider an assemble-to-order (ATO) manufacturer's...

Request-for-quote (RFQ) is the most common way for contractor selection, which is of vital importance to the success of project outsourcing. Project clients need to carefully design the RFQ mechanism to select and incentivize contractors properly. Problem definition: We study the RFQ design...

Ever-increasing coupling of energy and mobility sectors is under way in our cities. However, whether and how to use such coupling to optimize the portfolio and operations of urban energy assets has rarely been studied. We fill this gap by studying "omni-sharing,'' which is a novel business model...

Several design guidelines and flexibility indices have been developed in the literature to inform the design of flexible production networks. In this paper, we propose additional flexibility design guidelines for unbalanced networks, where the numbers of plants and products are not equal, by...

Request-for-quote (RFQ) is the most common way for contractor selection, which is of vital importance to the success of project outsourcing. Project clients need to choose from various available RFQ procedures to properly select and incentivize contractors. We study the RFQ design problem for...

Problem definition: Observing the retail industry inevitably evolving into omnichannel, we study an offline-channel planning problem that helps an omnichannel retailer make store location and location-dependent assortment decisions in its offline channel to maximize profit across both online and...

We study the reliable (uncapacitated) facility location (RFL) problem in a data-driven environment where historical observations of random demands and disruptions are available. Owing to the combinatorial optimization nature of the RFL problem and the mixed-binary randomness of parameters...
