Bunch technique for semionline with two groups of items is proposed in this paper. Algorithm to solve this problem is to distribute items from the first group bunch approach and after that apply $LS$-algorithm to assign items from the second group. In order to prove the estimation of our algorithm is introduced different types of bunches to distribute all items from the first group such a way that only one of the entered types of bunches are obtained. During the second stage we use $LS$ with worst case performance is at most $\frac{17}{9}$.
Keywords: bunch technique; semionline; partition; scheduling; worst case performance.
