Algorithms for linear and convex feasibility problems: A brief study of iterative projection, localization and subgradient methods
(Bilkent University, 1998)
Several algorithms for the feasibility problem are investigated. For linear systems, a number of different block projections approaches have been implemented and compared. The parallel algorithm of Yang and Murty is ...
A multi-modal discrete-event simulation model for military deployment
(Bilkent University, 2009)
This study introduces a logistics and transportation simulation as a tool that can be used to provide insights into potential outcomes of proposed military deployment plans. More specifically, we model a large‐scale ...
Robust portfolio optimization with risk measures under distributional uncertainty
(Bilkent University, 2016-08)
In this study, we consider the portfolio selection problem with different risk measures and different perspectives regarding distributional uncertainty. First, we consider the problem of optimal portfolio choice using the ...
Time/cost trade-offs in machine scheduling with controllable processing times
(Bilkent University, 2008)
Processing time controllability is a critical aspect in scheduling decisions since most of the scheduling practice in industry allows controlling processing times. A very well known example is the computer numerically ...
Centralized and decentralized management of water resources with multiple users
(Bilkent University, 2011)
In this study, we investigate two water inventory management schemes with multiple users in a dynamic game-theoretic structure over a two-period planning horizon. We first investigate the groundwater inventory management ...
Concepts and analysis in facility location under uncertainty : applications to 1-median problem
(Bilkent University, 2001-08)
Essays on scheduling with controllable processing times in flexible manufacturing systems
(Bilkent University, 2003)
Terrain visibility and guarding problems
(Bilkent University, 2017-11)
Watchtowers are located on terrains to detect fires, military units are deployed to watch the terrain to prevent infiltration, and relay stations are placed such that no dead zone is present on the terrain to maintain ...
Polyhedral Approaches to Hypergraph Partitioning and Cell Formation
(Bilkent University, 1994)
Hypergraphs are generalizations of graphs in the sense that each hyperedge can connect more than two vertices. Hypergraphs are used to describe manufacturing environments and electrical circuits. Hypergraph partitioning ...
Generating robust and stable machine schedules from a proactive standpoint
(Bilkent University, 2009)
In practice, scheduling systems are subject to considerable uncertainty in highly dynamic operating environments. The ability to cope with uncertainty in the scheduling process is becoming an increasingly important issue. ...
