If a work center is already loaded to full capacity, which of the following actions...

The correct answer is C. Choosing a feasible alternate routing .

When a work center is already fully loaded, releasing another order to that same work center would create overload, longer queues, and likely late orders. Before releasing the order, the planner should look for a feasible alternate routing or alternate work center with available capacity.

Exact extract: “If the preferred machine for a process cannot produce any more without overloading and possible loss of output quality another machine alternate routing operation or work centre may be chosen because it has spare capacity.”

The capacity planning material also states: “Alternate routing. Jobs may be routed away from overloaded to underloaded machines or work centres.”

Therefore, the best action before releasing the new order is to choose a feasible alternate routing .
