LINEAR PROGRAMMING TO SELECT AERATION DEVICES FOR FISH FARMS

Aeration and de-aeration at bottom aeration devices on spillways

Aeration devices are introduced along chute spillways and at bottom outlets to prevent cavitation damage in high velocity flows. Bottom aerators are characterised by large quantities of air entrained along the jet interfaces but also by a strong de-aeration process near the impact of the water jet with the spillway bottom. In this paper, the aeration and de-aeration occurring respectively in th...

A goal programming approach for fuzzy flexible linear programming problems

 We are concerned with solving Fuzzy Flexible Linear Programming (FFLP) problems. Even though, this model is very practical and is useful for many applications, but there are only a few methods for its situation. In most approaches proposed in the literature, the solution process needs at least, two phases where each phase needs to solve a linear programming problem. Here, we propose a method t...

Simulator Software for Marine Fish Farms Sustainability

One of the main costs of the marine fish farms is the extruded feed. This paper discusses many issues given when fish, mussels, oysters or other shellfish are fed and their relation with the sustainability. There are several simulator software for fish growth and there are several published models for sustainability, but, as far as we know, there are very few simulator software for marine fish ...

a new type-ii fuzzy logic based controller for non-linear dynamical systems with application to 3-psp parallel robot

abstract type-ii fuzzy logic has shown its superiority over traditional fuzzy logic when dealing with uncertainty. type-ii fuzzy logic controllers are however newer and more promising approaches that have been recently applied to various fields due to their significant contribution especially when the noise (as an important instance of uncertainty) emerges. during the design of type- i fuz...
