Supply chain management can increase productivity through efficiently use of equipments and manpower. However, preemptive orders occur with delivery deadline or other cost reasons that might decrease the productivity. This paper is aim to discuss proper preemptive order strategies based on three preemption strategies (Bock and Patterson, 1990): no preemption of resources (N (LPR). The th PR), absolute priority for resources (APR), and limited priority for resourcesree preemption rules are examined by an example of a production process for producing bicycles. The related data are collected by simulation with two observations: the production time and the delay duration. The results show that proper use of order preemptive strategies can reduce the impact of order preemption.
