A reduction strategy is a method of shortening the lead time of an order by reducingcertain time elements in the order scheduling1. The time elements that can be reduced by a reduction strategy are move time, wait time, and queue time2. Move time is the time required to move a material from one operation to another. Wait time is the time between the end of an operation and the start of the next operation. Queue time is the time before an operation can start at a work center due to the work center's capacity utilization3. These time elements can be reduced by a percentage or a fixed value in the reduction strategy.
