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.
