Fuzzy Logic Model of Nitrate Release from Polymer-Coated Fertilizers

In real world, mathematical model is commonly used to explain complicated
system so that people can understand the system or the behavior of the system easily.
Biopolymer is very useful and beneficial in various fields such as medical, agriculture,
bioengineering and so on. However, the complexity of the process of biodegradation
makes it difficult to optimize the design of polymers application. Chemical reactions
such as degradation of biopolymer usually take years and it costs a lot of money due
to the numerous experiments sets used. Therefore, the objectives of this project are to
apply fuzzy logic theory on modelling to find the effect of temperature on polymers
biodegradation, and to use the Matlab simulation to show the biopolymer degradation
behavior. In order to perform the fuzzy logic modelling, the scope of study involves
the basic knowledge on the fuzzy logic theory and fuzzy rules. Simple mathematical
modelling equations on degradation are used for simulation and performed in Matlab
to obtain the results for polymer biodegradation. Modelling can quickly predict the
nitrogen release profile for the biodegradation process and this becomes very helpful
in optimizing the design of polymer in many applications such as tissue engineering,
bone fixation, drug delivery, etc.
