  • M. Djunaidi, E. Setiawan, R. Fitriadi, Determination of lot size orders of furniture raw materials using dynamic lot sizing method In The 2018 2nd International Conference on Engineering and Applied Technology (ICEAT), 2018.


    Wisanka is an indoor and outdoor furniture manufacture and export company in
    Indonesia. In the production activities, inventory control of raw materials is very important and
    needs to be handled properly so that the production process can run smoothly and orders from
    consumers can be fulfilled in a timely manner. Problems faced in the company that there is no
    optimal planning in determining the size of ordering of raw materials. Reservations made
    during this only based on the quantity of raw materials ordered can meet the needs during a
    certain period without considering the total cost incurred. The main purpose of this research is
    to determine the policy of controlling raw material requirement for the coming period by
    paying attention to the inventory cost incurred. In this research used lot sizing technique based
    on Silver Meal algorithm and Wagner Within algorithm. The use of lot sizing technique based
    on Wagner Within algorithm resulted in a cost efficiency of 3.6% for klabang material while
    Silver Meal of 2.9% for semi-polished rattan and 3.4% for leles compared to the lot sizing
    technique applied by the company.
