We consider a single-server queueing system with Poisson arrivals in which the speed of the server depends on whether an associated fluid reservoir is empty or not. Conversely, the rate of change of the content of the reservoir is determined by the state of the queueing system, since the reservoir fills during idle periods and depletes during busy periods of the server. Our interest focuses on ...

In this paper, we show how a convex optimization methodology can be used to determine a static solution, representing exit-valve settings in a multi-node reservoir system. A tunedvalve algorithm is used to produce an optimal flow solution and is based on the objective of minimizing overall combined sewer overflow (CSO) reservoir spillage to receiving waters under a combination of dry and wet (s...

A dynamic water allocation framework for a multipurpose, single reservoir is formulated to utilize climate information based reservoir inflow forecasts to quantify the reliability of use for the given demand. Based on the semi-parametric approach of De Souza and Lall [2003], 12 months lead retrospective reservoir inflow forecasts were developed for the period July 1990June 2000 for the Oros res...

In this paper, ant colony optimization (ACO) algorithms are proposed for reservoir operation. Through a collection of cooperative agents called ants, the near-optimum solution to the reservoir operation can be effectively achieved. To apply ACO algorithms, the problem is approached by considering a finite horizon with a time series of inflow, classifying the reservoir volume to several interval...

Operation of multi-reservoir systems is known as complicated and often large-scale optimization problems. The problems, because of broad search space, nonlinear relationships, correlation of several variables, as well as problem uncertainty, are difficult requiring powerful algorithms with specific capabilities to be solved. In the present study a Self-adaptive version of Melody Search algorith...
