Due to of high capital necessities when introducing or upgrading a line, its con-figuration arranging is of incredible importance for specialists. Accordingly, this attracted attention of many researchers, who tried to support real-world configuration planning by suited optimization models (assembly line balancing problems). Disregarding the tremendous scholastic exertion in sequential construction system adjusting, there remains an impressive hole between necessities of genuine setup issues and the status of research. A Critical Path Method (CPM) based approach for assembly line has been applied for assigning the task to the work stations for assembly line layout. Results show that the CPM based approach performs better and improve the labor productivity of assembly line layout. In this Research we will use the proposed new approach to solve different types of ALBPs including the traditional straight-line ALBP and ALBP with parallel workstations. Numerical results of illustrative examples show the effectiveness of the proposed new approach.
