This paper discusses methods for solving the fuzzy assignment problem. Based on the addition rules for fuzzy numbers, the definition of the solution for fuzzy equation is used to calculate the difference of two fuzzy numbers. By use of the definition of the solution, the method for fuzzy assignment problem is developed, which is akin to the classical assignment problem. An example is given to illustrate the method. The solution of the fuzzy equation is also applied to critical path problem in project network planning with fuzzy environment.
