More precisely, we extend the method proposed by Wang and Curry by endogenously including competition. Indeed in their approach, competition is described exogenously and the model cannot take into account part-worth uncertainty for the competition’s products. Our extension permits us to take into account all effects of part-worth uncertainty, even those relative to the competition, and therefore improve substantially Wang and Curry’s approach. 000007045 540__ $$acorrect 000007045 592__ $$aHEG - Genève 000007045 592__ $$bCRAG - Centre de Recherche Appliquée en Gestion 000007045 592__ $$cEconomie et Services 000007045 65017 $$aEconomie/gestion 000007045 6531_ $$9eng$$ashare-of-choice model 000007045 6531_ $$9eng$$arobust optimisation 000007045 6531_ $$9eng$$aconjoint analysis 000007045 655__ $$ascientifique 000007045 700__ $$aMoresino, Francesco$$uHaute école de gestion de Genève, HES-SO Haute Ecole Spécialisée de Suisse Occidentale 000007045 773__ $$j2021, vol. 9, no. 3, article 288, pp. 1-10$$tMathematics 000007045 8564_ $$s1001105$$uhttps://arodes.hes-so.ch/record/7045/files/Published%20version.pdf$$99d00e9e3-e4d3-4f7e-b527-9c2956e0c529 000007045 906__ $$aGOLD 000007045 909CO $$ooai:hesso.tind.io:7045$$pECONOMIESERVICES_ALL$$pGLOBAL_SET$$pHEG_GE_ARTICLES_SCIENTIFIQUES$$qHEG_GE_ARTICLES_SCIENTIFIQUES_ECO 000007045 950__ $$aI2 000007045 980__ $$ascientifique 000007045 981__ $$ascientifique
