A large variation in the assembly times is observed among different product types when they are produced by a mixed-model assembly line. The variation reduces production efficiency and may cause a line stoppage. However, the variation of the assembly times can be reduced by installing a bypass line which processes a part of assembly operations of product with relatively longer assembly time. The paper presents that the installation of a bypass line will reduce the total line length of the entire assembly line as well as the variation of the assembly times. An optimization model and its branch and bound algorithm are developed to minimize the total line length. The decision variables are the number of stations for each of main and bypass lines and the product types to be processed at the bypass line. The computational efficiency is discussed through numerical examples.
