This paper examines two-stage multi-attribute decision strategies in different condi-<br>tions where numbers of alternatives, and attributes are varied. A Monte-Carlo com-<br>puter simulation using the concept of elementary information processes identified de-<br>cision strategies that approximate the accuracy of normative procedures while saving<br>cognitive effort in the two-stage decision making process. The elementary strategies<br>examined in the simulation were nine decision strategies: lexicographic, lexicographic<br>semi-order, elimination by aspect, conjunctive, disjunctive, weighted additive, equally<br>weighted additive, additive difference, and majority of confirming dimensions strategies.<br>Elementary information process and relative accuracy were computed for all combina-<br>tion of two decision strategies for two-phased decision making process. The result of<br>the computer simulation suggested that comparatively effortless and accurate heuristic<br>was the two-phased strategy that used lexicographic strategy to eliminate until a few<br>alternatives in the first stage and used weighted additive strategy in the second stage.<br>Lastly, theoretical and practical implications of this study were discussed.
