Claim One:
1. A method for designing an integrated computational element (ICE), comprising: generating a plurality of ICE designs with a design suite stored on a non-transitory, computer-readable medium, each ICE design having at least one of a random number of layers and a random thickness for each layer; optimizing the plurality of ICE designs based on performance criteria and thereby generating a plurality of theoretical ICE designs configured to detect a characteristic of interest; sorting the theoretical ICE designs based on the performance criteria in view of a known value for the characteristic of interest and thereby identifying one or more predictive ICE designs; approximating a spectral shift on each predictive ICE design resulting from an expected temperature shift, wherein approximating the spectral shift includes calculating a theoretical effect of the expected temperature shift on each individual layer of each predictive ICE design; altering a design of the one or more predictive ICE designs based on the calculated theoretical effect of the expected temperature shift; and selecting for fabrication one or more predictive ICE designs based on favorable temperature stability in view of the calculated theoretical effect of the expected temperature shift.
