Example 1 – Flux estimation. PMFA estimations were obtained for the example described in Figure 1. (A) The measured values are depicted with dashed lines. The computed possibility distributions are depicted with solid lines. (B) The Figure shows the flux intervals of conditional possibility 0.8 (box), 0.5 (thick line) and 0.1 (narrow line) and the maximum possibility flux estimation (square and circle for non-measured and measured fluxes, respectively).
