In this paper, we proposed a new bi-objective mathematical model for two stage assembly flow shop problem (TAFSP) in just in time environment. Assembly flow shop problem (AFSP) is a special type of flexible job shop problem that has two stages. Parallel and independent machines are exists in the first stage and only one machine (assembly machine) assembled jobs in the second stage. Each job consisted of m+1 operations that process on m+1 machines in the two stage respectively. We applied -constraint method as exact approach to validate the proposed model and obtain fronts of the solutions in the solution space.
