The study describes a Grammatical Evolution (GE) system and applies it to establish the inflow prediction model of Der-Ji Reservoir in central Taiwan. GE is a new computing architecture in the area of optimization. It provides system identification in a transparent and structured way; a fittest function type of input-output relationship will be obtained automatically from this method. A multi-...

There is an increasing awareness among irrigation planners and engineers to design and operate reservoir systems for maximum efficiency to maximise their benefits. Accordingly, significant work has been done on reservoir operation for known total irrigation demand and on the optimal allocation of water available to crops at the farm level. This present paper deals with the development and compa...

A reservoir operation model of Mun Bon and Lam Chae reservoirs was developed to simulate reservoir operation using a hedging policy. A variety of common hedging forms was specified, including one-point hedging, two-point hedging and zone-based hedging. The simulated results were compared with the standard operating policy and probability based rule curve. The percentage of failure frequency, av...

This study demonstrates running a complicated multi-reservoir system with numerous goals. The heavily incorporates demand and input uncertainties. Fuzzy set theory, which is robust significantly impacted by this uncertainty. fuzzy linear programming method utilized in to find the best course of action for system’s functioning when there uncertainty various parameters, including availability res...

The mixed linear programming model is commonly recognized to be an effective means for searching optimal reservoir operation policy in water resources system. In this paper a multi-objective mixed integer linear programming model is set up to obtain the optimal operation policy of multi-reservoir water supply system during drought, which is able to consider the operation rule of reservoir-group...

Aiming at sustainable development, decision-making for operation of large dams requires the assessment of complex interrelations with neighbouring environmental, economic and social subsystems. To solve this kind of highly unstructured problems often DSS are recommended. This paper presents strengths and weaknesses of DSS application in general, focusing however on large dam operation. A charac...
