Complex Models	Complex models are multilevel ANP models, usually with Benefits, Opportunities, Costs and Risks subnets.  In many of the models, attached files such as Powerpoint slides shows, Word documents, Excel files and other types of files such as Expert Choice hierarchical models are accessible when the model is opened via the paperclip icon on the toolbar.
Hierarchical Models	Hierarchical models include ones that are  trees, complete hierarchies and other hierarchical structures.  In many of the models, attached files such as Powerpoint slides shows, Word documents, Excel files and other types of files such as Expert Choice hierarchical models are accessible when the model is opened via the paperclip icon on the toolbar.
Market Share Models	Market share models are single level network models with feedback and interdependence in many cases that are used to estimate relative market share of products, merchandisers, radio stations, phone service, etc.  Many of the market share model results are compared against actual data.  Again in many of the models, attached files such as Powerpoint slides shows, Word documents, Excel files and other types of files such as Expert Choice hierarchical models are accessible when the model is opened via the paperclip icon on the toolbar.
Resource Allocation Models	Resource allocation models are usually models that have ratings components where the alternatives are evaluated and by using their performance scores resources may be allocated using an optimization process.  Again in many of the models, attached files such as Powerpoint slides shows, Word documents, Excel files and other types of files such as Expert Choice hierarchical models are accessible when the model is opened via the paperclip icon on the toolbar.
