A. Fakirian et al., APPLICATION OF MULTICRITERIA OPTIMIZATION TO THE DEVELOPMENT OF THERMOLUMINESCENT ANALYSIS - STUDY ON IRRADIATED HERBS, Analusis, 23(3), 1995, pp. 140-145
We have used the multiple criteria optimisation techniques to determin
e the optimal utilization conditions of a thermoluminescence reader. A
fter determination of the main factors (particule size, sample quantit
y, heating rate, nitrogen flow), the modelisation has been made using
a Doehlert matrix Study of the response equation, and the canonic equa
tion, show that the optimums are different for the two experimental re
sponses studied. The 'desirability' permits to transform this response
s into a unique quantitative measure who represent the global quality
of the compromise, expressed in a satisfactory percentage by reference
s to the objectives. We can thus obtain the experimental value of fact
ors who allowed a high difference between the thermoluminescence signa
l of irradiated and unirradiated samples, and a low variation coeffici
ent.
