[Kobryn 2017] Digital Twin vs. Physical Twin Equivalency Test
"A reasonable litmus test for a Digital Twin is analogous to the Turing Test for AI. Let:
- ST = System Tester
- PS = Physical System
- PT = Physical Twin representation of PS
- DT = Digital Twin of PT
- V&V-TS = robust Verification & Validation Test Suite shared by PT and DT
If ST executes V&V-TS against both PT and DT, but cannot reliably distinguish DT from PT with probability greater than 80%, then DT is a bona fide Digital Twin of PT:
P(ST correctly distinguishes DT from PT | V&V-TS) <= 0.80— Cris Kobryn, Founder & CTO, PivotPoint Technology Corp. (2017)
