ELTRUN Director: Professor Georgios I. Doukidis
ELTRUN is the E-Business Center of the Athens University of Economics and Business. ELTRUN currently consists of more than 20 researchers, including 4 members of the academic staff of Athens University of Economics and Business, while there is close cooperation with academic staff of other Institutions. Through the years, ELTRUN has successfully managed to produce state-of-the-art research and to complete more than 40 international research projects some of them funded by the Information Society and Technologies Program of the European Commission. In these international research projects, ELTRUN has collaborated closely with over 50 international companies such as: Microsoft, Nokia, Unisys, Sema, Sonera, Manesman, Procter & Gamble, Oracle, Ericsson etc. and world-class Institutions such as LSE, INSEAD, St. Gallen, MIT, Cologne, Esade, Erasmus, Cambridge etc. The center is also actively involved in national research programs, in various activities that are intended to increase awareness in the fields of E-Business.
ELTRUN is currently organized in the following research groups:

The stable Supply Chain Network (SCN) configuration, introduced by Ostrovsky [11], is defined on a finite set of agents A that can be divided into k finite disjoint sets, A1 being the set of suppliers, Ak the set of final consumers, and Ai, i={2,3,…,k-1}, the sets of intermediary agents, and asks for a chain stable allocation of the agents. In our current work we present a specialized version of Ostrovsky’s generic framework, and prove that, under this setting, any k-sided SCN can be decomposed to k-1 united SM sub-markets. Moreover, we implement T-algorithm, presented in [11], as a generalization of the Gale-Shapley algorithm [7], and show how an intermediary-optimal solution can be derived, while we prove that the lattice formed by the set of solutions is distributive.
