Data Sciences and Operations Faculty

Welcome to the DSO Faculty and Research webpage!

Our society faces wicked problems – global pandemics, climate change, extreme wealth inequity, and a ubiquity of opaque artificial intelligence algorithms that unintentionally increase ideological polarization and institutionalize discrimination. As we collectively search for a solution, emerging fields such as sustainable & smart supply chains, fair machine learning, and evidence-driven public policy offer a path forward.

The DSO department at USC Marshall is a unique place where one can find world experts in these, and other, areas of data science.

The department consists of three groups – information systems, operations management, and statistics. Faculty collaborate within and across these groups to:

i) Teach classes that prepare students to thrive in an increasingly data-driven world, and

ii) Conduct exciting, relevant research that pushes the boundaries of human knowledge. Importantly, faculty research spans both theoretical breakthroughs in fundamental science and practical strategies to help companies, governments, and non-profits better navigate those wicked problems.

You can learn more about our faculty, their research, and their outstanding scholarly achievements on this page and their linked personal websites below.

Abstract

In a non-negative profit game that possesses a Population Monotonic Allocation Scheme (PMAS), being a member of a larger coalition implies that your profit cannot decrease. In this paper, we refer to such games as PMAS profit games. As population monotonicity is a nice and desirable property that encourages formation of larger coalitions and implies stability of the grand coalition, we explore if this special feature of PMAS games can help in identifying additional stable coalition structures under different stability concepts in cooperative game---namely, core partitions, the von Neumann--Morgenstern (vNM) stable set, the largest consistent set, and the equilibrium process of coalition formation (EPCF)---and in developing relationships between coalition structures that are stable under these different stability concepts.
We first define two special classes of players for PMAS profit games---extreme and strong players---and use them to develop an algorithm for construction of stable (core) partitions. We also use extreme players to identify absorbing states for equilibrium processes of coalition formation with high level of farsightedness.
We then explore the impact of population monotonicity on the relationship between stable coalition structures under abovementioned stability concepts. While we are able to obtain some results related to stability of the grand coalition and to establish relationships between stable coalition structures under different stability notions that are consistent with the existing body of knowledge, population monotonicity in general does not add enough for strengthening of the existing results. However, we are able to show a couple of more general result that hold for arbitrary cooperative TU profit games. That is, we show that the members of vNM farsighted stable sets are core partitions, and that core partitions are members of a vNM stable sets. Moreover, we show that the members of vNM farsighted stable sets are EPCF-stable partitions.

Abstract

We study a special class of cooperative games with transferable utility (TU), called m-attribute games. Every player in an m-attribute game is endowed with a vector of attributes that can be combined in an additive fashion; that is, if players form a coalition, the attribute vector of this coalition is obtained by adding the attributes of its members. Another fundamental feature of m-attribute games is that their characteristic function is defined by a continuous attribute function—the value of a coalition depends only on evaluation of on the attribute vector possessed by the coalition, and not on the identity of coalition members. This class of games encompasses many well-known examples, such as queueing games and economic lot-sizing games. We believe that by studying attribute function and its properties, instead of specific examples of games, we are able to develop a common platform for studying different situations and obtain more general results with wider applicability. In this paper, we first show the relationship between nonemptiness of the core and identification of attribute prices that can be used to calculate core allocations. We then derive necessary and sufficient conditions under which every m-attribute game embedded in attribute function has a nonempty core, and a set of necessary and sufficient conditions that should satisfy for the embedded game to be convex. We also develop several sufficient conditions for nonemptiness of the core of m-attribute games, which are easier to check, and show how to find a core allocation when these conditions hold. Finally, we establish natural connections between TU games and m-attribute games.
