Definition
Mix: The product mix can be adjusted and the capacity remains fixed.
In detail
The planning time fence is the middle segment of time fences, where the product mix can be adjusted but capacity is fixed. It addresses how to optimize product structure in the medium term while maintaining capacity stability. It differs from the rate time fence, which allows capacity adjustments. Typical output includes rules for product mix adjustments, guiding planners on when product switching can occur.
Example in practice
Within the planning time fence, the marketing department proposes an increase in demand for one product and a decrease for another. The planner adjusts the production sequence according to the rules, increasing the schedule for the hot-selling product and reducing the slow-moving one, without changing capacity, thus meeting market demand.
