optimization.
Protect the flow. Hold WIP with a purpose.
We test where buffer stock keeps a line running, where more stock stops helping, and what it may be hiding.
The real challenges.
Too little WIP can starve a line; too much can occupy space and conceal interruptions. Explore five decisions behind an effective buffer using the cards or arrows below.

The results.
A buffer study makes the inventory–output tradeoff visible before changing physical stock levels on the floor.
Size each buffer for its purpose
See where stock protects output and where adding more has little effect.
Rank buffers by their value
Test removing or reducing each location and compare the effect on delivered output.
Measure coverage in minutes
Know how long downstream work continues when an upstream process stops.
Set clearer refill rules
Compare when and how WIP is replenished before a line runs dry.
Expose the underlying loss
Distinguish useful protection from stock that masks a reliability or cycle-time problem.

Buffer & inventory consulting
Decide where WIP belongs, how much is useful, and when it should be replenished. We test buffer policies against production variability before changing stock levels or floor space.
Explore our simulation project supportBuffer size and diminishing output returns
Compare delivered output across candidate buffer sizes to locate diminishing returns. We include variability and stops on both sides of the buffer so useful running protection can be distinguished from stock that adds little capacity.
The value of each buffer location
Reduce or remove each buffer in the model and compare the effect on output and waiting. The findings help prioritize locations that protect flow and identify stock that may be compensating for a process or reliability problem.
Running-time coverage during upstream stops
Simulate upstream stops and measure how long downstream production continues before the buffer drains. We compare that coverage with replenishment and recovery times, expressing protection in running minutes as well as units held.
A study built around your operation
We define the sections of the line and the stock policies under consideration. Finite buffers are tested alongside upstream and downstream processes so reductions in WIP are assessed against delivered output, not inventory quantity alone.
Inputs for a credible comparison
Typical inputs include buffer locations and capacities, cycle-time variation, failure and recovery records, replenishment triggers and lead times, product mix, and shift handovers. We check how stock fills and drains in the current operation.
Findings for your next decision
Depending on scope, receive output-versus-WIP comparisons, buffer-location rankings, coverage in running minutes, and replenishment recommendations. Findings distinguish useful protection from inventory that compensates for a reliability or flow problem.
