At its core, PPC translates customer demand into an optimized, executable plan for materials, machines, and people, and then monitors and adjusts execution to meet targets for delivery, cost, and quality. The primary objective of PPC is to synchronize demand and supply so customers receive the right products on time at the lowest feasible cost.

When multiple products share the same machines, scheduling becomes complex. The text introduces optimization algorithms, such as Johnson’s Rule, to sequence jobs in a way that minimizes total idle time (makespan). 3. Real-World Applications Across Industries

Techniques for predicting future demand, including time-series and qualitative methods.
