Design of any product is associated with a number of elements like technical parameters, material properties, functional and geometrical interdependence, etc. A balance between the technical parameters and creativity is necessary for a successful product design. To address this, a mathematical model is generally proposed, which many times, may not be a correct representation. For mathematical models, the tendencies and relationships remain true for a specified period of time only. The applications of fuzzy for the design decision deliver accurate information related to customer needs. In this paper, a design method for the reservoir of an air cooler is proposed to handle uncertainty using fuzzy logic. This method helps develop a dedicated tool for handling uncertainty and allows to take advantage of the creativity-based design process to achieve the goals of innovative product design.

Keywords: design decission, uncertainty, fuzzy logic
