On the S-procedure and some variants
We give a concise review and extension of S-procedure that is an instrumental tool in control theory and robust optimization analysis. We also discuss the approximate S-Lemma as well as its applications in robust optimization.
Analysis of the Behavior of Transient Period in Non-Terminating Simulations
Computer simulation is a widely used tool for analyzing many industrial and service systems. However, a major disadvantage of simulation is that the results are only estimates of the performance measures of interest, hence ...
Optimal hybrid control of a two-stage manufacturing system
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 ...
Scheduling in a three-machine flexible robotic cell
In this study, a three-machine flexible robotic manufacturing cell in which the CNC machines are used is considered. These machines are highly flexible and are capable of performing several different operations. Each machine ...
Huber approximation for the non-linear ℓ1 problem
The smooth Huber approximation to the non-linear ℓ1 problem was proposed by Tishler and Zang (1982), and further developed in Yang (1995). In the present paper, we use the ideas of Gould (1989) to give a new algorithm with ...
Auction based scheduling for distributed systems
(International Institute of Informatics and Systemics, 2006)
Businesses deal with huge databases over a geographically distributed supply network. When this is combined with scheduling and planning needs, it becomes too difficult to handle. Recently, Fast Consumer Goods sector tends ...
Formulations and valid inequalities for the heterogeneous vehicle routing problem
We consider the vehicle routing problem where one can choose among vehicles with different costs and capacities to serve the trips. We develop six different formulations: the first four based on Miller-Tucker-Zemlin ...
Contractual agreements for coordination and vendor-managed delivery under explicit transportation considerations
(John Wiley & Sons, 2006)
We consider the coordination problem between a vendor and a buyer operating under generalized replenishment costs that include fixed costs as well as stepwise freight costs. We study the stochastic demand, single-period ...
A novel optimization algorithm for video placement and routing
(Institute of Electrical and Electronics Engineers, 2006)
In this paper, we propose a novel optimization algorithm for the solution of the video placement and routing problem based on Lagrangean relaxation and decomposition. The main contribution can be stated as the use of integer ...
