Abstract:Based on the analysis for the unimodality of the single-period inventory, that of the two-timing ordering inventory for the manufacturers is studied. In order to modify this character, the virtual model and the function for the sellers are analyzed. Then if the demand density function is unimodal, then the profit function is quasi-concave over the support of the distribution is provided.
Keywords:inventory model quasi-unimodality concavity two-time ordering
