“…There likely exists additional facets containing information about the possible trade-offs. Several studies have examined the DEA estimated tradeoffs including Podinovski (2019) and Asmild, Paradi, & Reese (2006) To identify all the existing facets of the convex hull of the observations, we use the QHull algorithm (Barber, Dobkin, & Huhdanpaa, 1996), but from those only consider the subset of facets indicating the frontier in a CRS model and augmented with facets generated by the free disposability assumption in DEA. Petersen & Olesen (2015) offer an algorithm using QHull to find all possible facets in CRS and VRS.…”

“…Podinovski et al [18] calculated different directional differentials for some technologies organized as polyhedral sets such as the ones with weakly disposable undesirable products using a unified linear method. Podinovski [17] discussed more about the application of the technique presented by Podinovski et al [18] to technologies with weakly disposable undesirable outputs and dealt with different marginal rates and elasticity measures.…”
