Production planning and control: In manufacturing, what does “routing” specifically determine?

Introduction / Context:
Production Planning and Control (PPC) comprises routing, scheduling, dispatching, and expediting. Each function plays a distinct role from deciding “how to make” to “when to start” and “how to keep work flowing.”

Given Data / Assumptions:

• A multi-step manufacturing process exists.
• Machines and work centers have defined capabilities.
• Material, tooling, and methods are known.

Concept / Approach:
Routing answers “where and in what order?” It sets the route sheet: the list and sequence of operations, machines, jigs/fixtures, and sometimes standard times. Scheduling answers “when?” Dispatching issues orders to commence; expediting monitors progress and resolves delays.

Step-by-Step Solution:

Verification / Alternative check:
Cross-check with process plans and value-stream maps; the route must respect precedence constraints.

Why Other Options Are Wrong:
Scheduling is timing; dispatching is releasing work; expediting is control during execution. They are different PPC functions from routing.

Common Pitfalls:
Confusing routing with line balancing; ignoring setup families that affect the optimal path.

Final Answer:
The prescribed sequence of operations to be followed
