MPS vs MRP vs APS in food manufacturing
MPS, MRP, and APS are three layers of production planning. MPS (Master Production Schedule) decides which finished products to make and when. MRP (Material Requirements Planning) calculates the ingredients and packaging needed for that schedule. APS (Advanced Planning and Scheduling) sequences the actual work against real constraints like shelf life, allergens, changeovers, and finite line capacity.
What is the difference between MPS, MRP, and APS?
The three sit in a hierarchy. MPS (Master Production Schedule) is the demand-facing layer. From forecasts and confirmed orders it decides which finished SKUs to produce and in what quantities over a horizon. MRP (Material Requirements Planning) takes that schedule, explodes the bill of materials, and computes time-phased requirements for ingredients, cultures, and packaging, telling you what to buy or make and when. APS (Advanced Planning and Scheduling) is the execution layer. It sequences specific jobs on specific lines against real constraints instead of assuming infinite capacity.
Why does this matter in food and beverage?
MPS and MRP were built for stable, dependent demand. Food and beverage rarely cooperates. Ingredients and finished goods carry hard shelf-life deadlines, allergen rules dictate run order, and every product switch can trigger a full CIP washdown that eats line time. Classic MRP assumes infinite capacity and ignores sequence, so its plan looks valid on paper but breaks on the floor. APS adds finite capacity scheduling, FEFO logic, and sequence-dependent changeovers, which is why most serious food and beverage planning now happens at the APS layer.
How Semia handles this
Semia is the AI employee for food and beverage production planning. It reads orders, inventory, ingredient and shelf-life status, attendance, and machine status, then writes tomorrow's plan with the constraints APS cares about: capacity, FEFO, allergen sequencing, and changeovers, all reconciled in one pass. A named human reviews and signs off before anything reaches the floor.
