Prof. Edward AndersonThe University of SydneyTalk:Competing for contracts with buyer uncertainty: Choosing price and quality variablesAbstract:We model a situation in which a single firm evaluates competing suppliers and selects just one. Suppliers have a convex cost function for the quality offered and submit bids involving both price and quality variables. The buyer makes a choice that, from ...

Prof. Lucy Gongtao ChenNational University of SingaporeTalk:Managing Operational and Financing Decisions to Meet TargetsAbstract: In this study we investigate the impact of a target on firms' operational (in particular, inventory) and financing decisions. Different than the existing approach that maximizes the probability of the profit reaching targets, we model the effect of targets by optimiz...

Prof. Xin ChenUniversity of Illinois at Urbana-ChampaignTalk:Sparse Solutions to Complex ModelsAbstract:Recent years witnessed the proliferation of the notion of sparsity and its applications in operations research models. In this talk, I present a wide range of complex models which admit sparse yet effective solutions. The examples range from compressed sensing, optimization problems, game the...

Prof. Ramandeep S. RandhawaUniversity of Southern CaliforniaTalk:Using fluid approximations for designing service systemsAbstract:Service systems tend to be very complicated to analyze exactly. This has led to a large literature aimed at developing good approximations of performance measures of interest, and then further using these for decision making, in particular, for capacity selection, ro...

Prof. Peng SunDuke UniversityTalk:Analyzing Scrip SystemsAbstract:Scrip systems provide a non-monetary trade economy for exchange of resources. We model a scrip system as a stochastic game and study system design issues on selection rules to match potential trade partners over time. We show the optimality of one particular rule in terms of maximizing social welfare for a given scrip system that...

Under the nested logit model, a customer associates a random utility with each product, and this random utility has some type of...
