    • Constrained optimal hybrid control of a flow shop system 

      Gokbayrak, K.; Selvi, O. (Institute of Electrical and Electronics Engineers, 2007)
      We consider an optimal control problem for the hybrid model of a deterministic flow shop system, in which the jobs are processed in the order they arrive at the system. The problem is decomposed into a higher-level ...
    • A Differential game model of opinion dynamics: Accord and discord as nash equilibria 

      Niazi, Muhammad Umar B.; Özgüler, A. Bülent (Birkhauser, 2020-03)
      This paper presents a noncooperative differential (dynamic) game model of opinion dynamics with open-loop information structure. In this game, the agents’ motives are shaped by their expectations of the nature of others’ ...
    • Dynamic bidding strategies in search-based advertising 

      Dayanik, S.; Parlar, M. (Springer, 2013)
      Search-based advertising allows the advertisers to run special campaigns targeted to different groups of potential consumers at low costs. Google, Yahoo and Microsoft advertising programs allow the advertisers to bid for ...
    • Inverse optimal control and positive real systems 

      Ünal Yılmaz (Bilkent University, 1997)
      In this thesis an inverse optimal control problem for constant output feedbacks is investigated. Necessary and sufficient conditions for optimality of an output feedback are derived for single-input, single-output systems. ...
    • Learning the optimum as a Nash equilibrium 

      Özyıldırım, S.; Alemdar, N. M. (Elsevier BV, 2000)
      This paper shows the computational benefits of a game theoretic approach to optimization of high dimensional control problems. A dynamic noncooperative game framework is adopted to partition the control space and to search ...
    • A noncooperative dynamic game model of opinion dynamics in multilayer social networks 

      Niazi, Muhammad Umar B. (Bilkent University, 2017-08)
      How do people living in a society form their opinions on daily or prevalent topics? A noncooperative di erential (dynamic) game model of opinion dynamics, where the agents' motives are shaped by how susceptible they are ...
    • Optimal control in infinite horizon problems: a Sobolev space approach 

      Le Van, C.; Boucekkine, R.; Saglam, C. (Springer, 2007)
      In this paper, we make use of the Sobolev space W{1,1}ℝ+, ℝn to derive at once the Pontryagin conditions for the standard optimal growth model in continuous time, including a necessary and sufficient transversality condition. ...
    • Optimal control of single-stage hybrid systems with poisson arrivals and deterministic service times 

      Gökbayrak, Kağan; Mısırcı, Muzaffer (IEEE, 2005)
      We tackle an optimal control problem for a single-stage hybrid system with Poisson arrivals and deterministic service times. In our setting, not only that the optimization problem is non-convex and non-differentiable, but ...
    • Optimal hybrid control of a two-stage manufacturing system 

      Gökbayrak, Kağan; Selvi, Ömer (IEEE, 2006)
      We consider a two-stage serial hybrid system for which the arrival times are known and the service times are controllable. We derive some optimal sample path characteristics, in particular, we show that no buffering is ...
    • Parameter identification for partially observed diffusions 

      Dabbous, T.E.; Ahmed, N.U. (Kluwer Academic Publishers-Plenum Publishers, 1992)
      In this paper, we consider the identification problem of drift and dispersion parameters for a class of partially observed systems governed by Ito equations. Using the pathwise description of the Zakai equation, we formulate ...
    • Service time optimization of flow shop systems 

      Selvi, Ömer (Bilkent University, 2008)
      One of the key questions that engineers face in áow shop systems is the service time control, i.e., how long jobs should be processed at each machine. This is an important question because processing times can have great ...
    • Technical note-optimal structural results for assemble-to-order generalized M-Systems 

      Nadar, E.; Akan, M.; Scheller-Wolf, A. (INFORMS Inst.for Operations Res.and the Management Sciences, 2014)
      We consider an assemble-to-order generalized M-system with multiple components and multiple products, batch ordering of components, random lead times, and lost sales. We model the system as an infinite-horizon Markov ...
