model uncertainty model technical uncertainty Jinjing Guo https://www.tandfonline.com/doi/abs/10.1076/iaij.4.1.5.16466 Oliver He uncertainty arising from the computer implementation of the model.Model technical uncertainty is the uncertainty generated by software or hardware errors, i.e. hidden flaws in the technical equipment. Software errors arise from bugs in software, design errors in algorithms and typing errors in model source code. Hardware errors arise from bugs, such as the bug in the early version of the Pentium processor, which gave rise to numerical error in a broad range of floating-point calculations performed on the processor.
