A perceptual computer software model applied to hierarchical decision making

Perceptual computer (Per-C) is a concept introduced in year 2001 by Mendel. It employs the Zadeh's theory of Computing With Words to provide a model for computer and software architectures able to aid people making subjective judgments. It can be used for variety of tasks like investment decision making, social judgment making, hierarchical decision making and so on. In this paper the topic of hierarchical decision making and related introductory terms are summarized and partly reinterpreted. A newly developed application programming interface (API) for software implementations of Per-C is presented, along with several new technical details. The API has been tested on the well known problem of missile system selection from the literature. The results have been compared with those from Wu and Mendel.
