Mixing, Blending & Industrial Batch Processing calculator
Capacity Gap Calculator
Check whether weekly batch demand fits your available schedule. Enter complete available and required batches on the same size basis, plus cycle hours for each additional batch.
What this calculator does
- Find missing weekly batches and the additional serial mixer hours needed to cover them.
Formula used
- Missing batches = max(0, required batches − available batches)
- Capacity balance = available batches − required batches
- Additional mixer hours = missing batches × complete cycle hours
Inputs explained
- Available Batches per Week: Complete same-size batches supported by the staffed weekly schedule.
- Required Batches per Week: Complete same-size batches required by the weekly production plan.
- Complete Cycle per Added Batch: Measured charging, mixing, discharge, and cleaning time per batch.
How to use the result
- Best suited to weekly production planning, overtime capacity sizing.
- Weekly capacity arithmetic does not resolve due-date sequencing or parallel equipment constraints.
Common questions
- What if the week has several different products? Calculate each compatible batch family separately or convert demand into demonstrated mixer hours. Different sizes and cycle times are not interchangeable batch counts.
- Should downtime be subtracted again? No. Available batches should already reflect the actual staffed schedule and planned downtime. Subtracting it again understates capacity.
- Why does zero demand return zero additional hours? No production is required for that batch family. Available capacity remains visible in the signed balance, while the shortage stays zero.
- Are additional mixer hours the same as overtime? Not necessarily. They are processing hours needed on equivalent equipment. Staffing, parallel mixers, and the calendar determine whether overtime is required.
