Finite perturbation analysis methods for optimization of inventory systems with non-stationary Markov-modulated demand and partial information
(Bilkent University, 2018-01)The state of the economy may fluctuate due to several factors, and the customer demand is a affected from the fluctuations of the state of the economy. Although the inventory holders can predict the state of the ... -
Finite perturbation analysis methods for optimization of periodic (s, S) inventory control systems
(Bilkent University, 2008)We are dealing with single item inventory systems where the period time is constant and the unsatisfied demands are backordered. The demands are independent and identically distributed random variables, but the distribution ... -
Joint routing, gateway selection, scheduling and power management optimization in wireless mesh networks
(Bilkent University, 2011)The third generation (3G) wireless communications technology delivers user traffic in a single step to the wired network via base station; therefore it requires all base stations to be connected to the wired network. On ... -
Service time optimization of flow shop systems
(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 ... -
Solution methods for planning problems in wireless mesh networks
(Bilkent University, 2012)Wireless Mesh Networks (WMNs) consist of a finite number of radio nodes. A subset of these nodes, called gateways, has wired connection to the Internet and the non-gateway nodes transmit their traffic to a gateway node ... -
Structural results for average-cost inventory models with partially observed Markov-modulated demand
(Bilkent University, 2018-05)We consider a discrete-time in nite-horizon inventory system with full backlogging, deterministic replenishment lead time, and Markov-modulated demand. The actual state of demand can only be imperfectly estimated based ...
