DISTRIBUTION CENTER CAPACITY PLANNING & SIMULATION
Test the plan before the volume arrives.
A daily volume total does not show when the work reaches each process or where it will wait. Capacity planning connects demand, timing, process rates, labor, and operating constraints to test what the building can realistically support.
Obsidian Axis Group helps distribution leaders compare operating scenarios before committing to staffing, layout, or capital decisions.
Questions the work can address
- Which process reaches its limit first as volume rises?
- How does order mix change the labor requirement?
- What happens when inbound timing or downstream availability changes?
- How much productive time does the staffing plan actually provide?
- Which assumptions have the greatest effect on the result?
What you receive
An agreed model or analysis for the question in scope, its assumptions and data sources, scenario comparisons, and the operating implications. Where a more detailed simulation is justified, its scope and validation approach are defined before the build.
The result should explain the conditions under which the plan works, not simply produce a single capacity number.
Example: the same daily volume can create different pressure.
If a large share of work arrives shortly before a shipping cutoff, a daily average can hide the queue that forms in the final hours. A useful scenario examines timing by process as well as total units. This example illustrates a planning question; it is not a forecast for your site.
What your team provides
Demand and mix assumptions, process rates, staffing patterns, available hours, operating calendars, layout or flow information, and known restrictions. Data limitations and estimates are recorded so users understand how much confidence to place in the output.
How success is agreed
The analysis answers the agreed planning question, is checked against available operating evidence, and makes the tradeoffs and uncertainty visible. Implementation results depend on whether the assumptions hold in practice.
Practical questions
Do we always need a simulation?
No. A simpler capacity model may answer the question. The level of detail should match the decision and the available evidence.
Can you evaluate peak staffing?
Yes. The scope can include productive hours, process rates, mix, ramp, and other relevant constraints rather than relying only on last year's headcount.
Is the output a guaranteed throughput commitment?
No. It is a decision tool with explicit assumptions. The operating team needs to validate and monitor the conditions that support the plan.
Tell us which decision the plan needs to support.
Describe the volume change, the constraint you suspect, and what you need to decide.
