She saved the model as Door_Line_3_Fixed.spp .

She realized her mistake. She had used the default “Normal Distribution” for the robot’s cycle time. But real robots sometimes stalled for 5 seconds to clean their nozzles. She double-clicked the welding robot, opened the tab, and changed the distribution to “Negative Exponential.” She added a 2% Failure Rate with a repair time of 10 seconds.

“Impossible,” she muttered. “In real life, that robot is fine.” tecnomatix plant simulation tutorial

She re-ran the simulation—this time for 8 hours of simulated time.

She hit the button—the green triangle icon that always made her nervous. She saved the model as Door_Line_3_Fixed

@10:15: operator.break := true @10:30: operator.break := false With a triumphant click, she ran the final simulation. The tool displayed a beautiful, flat line. Throughput: 120 doors per hour. No red buffers. No idle robots.

Tick. The first door panel appeared. Tick. It moved to the buffer. Tick. The welding robot grabbed it. But real robots sometimes stalled for 5 seconds

But then, chaos. The welding robot took 45 seconds. The painting robot after it took only 20 seconds. Soon, the buffer overflowed, glowing an angry red. Doors piled up in a digital traffic jam. The (her favorite tool) lit up like a Christmas tree: Station: Welding Robot. Utilization: 178%.
