One-line model description	Fuzzy logic model to model microbial reef development
Extended model description	FuzzyReef is a three-dimensional (3D) numerical stratigraphic model that simulates the development of microbial reefs using fuzzy logic (multi-valued logic) modeling methods. The flexibility of the model allows for the examination of a large number of variables. This model has been used to examine the importance of local environmental conditions and global changes on the frequency of reef development relative to the temporal and spatial constraints from Upper Jurassic (Oxfordian) Smackover reef datasets from two Alabama oil fields. The fuzzy model simulates the deposition of reefs and carbonate facies through integration of local and global variables. Local-scale factors include basement relief, sea-level change, climate, latitude, water energy, water depth, background sedimentation rate, and substrate conditions. Regional and global-scale changes include relative sea-level change, climate, and latitude.

Describe processes represented by the model	Process: carbonate productivity and deposition winnowing reef development carbonate depositional facies Model determines these through five deterministic and fuzzy steps: data input data fuzzification fuzzy rule analysis aggregation of results defuzzification
Describe key physical parameters and equations	See above
Describe length scale and resolution constraints	Model does not place any spatial constraints.
Describe time scale and resolution constraints	Temporal scale and resolution determined by user. Model adjusts process and output to the temporal increment chosen by user.
Describe any numerical limitations and issues	Some of the fuzzy logic methods do not produce unique results as there are a variety of method choices that best 'match' test data. For example, the user can choose a variety of aggregation methods to calculate final carbonate facies and productivity values.
