Optimization of Fuzzy Zero- Base Budgeting

Zero-Base Budgeting (ZBB) is a very well-known method for the selection and management of budgets and is widely used by companies and government agencies. In this paper, a new method for modelling ZBB in fuzzy environment is described. Triangular fuzzy numbers are used for describing the imprecise budget data. In addition, an alternative approach is proposed for people who need to be more precise in their requirements. The efficiency of the proposed method is illustrated by numerical example using triangular fuzzy numbers and possibility theory.
