A new look at the role of players’ weights in the weighted Shapley value

Radzik, Tadeusz - In: European Journal of Operational Research 223 (2012) 2, pp. 407-416

everal new families of semivalues for weighted n-person transferable utility games are axiomatically constructed and discussed under increasing collections of axioms, where the weighted Shapley value arises as the resulting one member family. A more general approach to such weighted games...

Absolute optimal solution for a compact and convex game

Nessah, Rabia; Tazdaı¨t, Tarik - In: European Journal of Operational Research 224 (2013) 2, pp. 353-361

This paper investigates the existence of absolute optimal solutions for a partition P in continuous and quasiconcave games. We show that the P-consistency property introduced in the paper, together with the quasiconcavity and continuity of payoffs, permits the existence of P-absolute optimal...

Notes on ‘Hit-And-Run enables efficient weight generation for simulation-based multiple criteria decision analysis’

van Valkenhoef, Gert; Tervonen, Tommi; Postmus, Douwe - In: European Journal of Operational Research 239 (2014) 3, pp. 865-867

In our previous work published in this journal, we showed how the Hit-And-Run (HAR) procedure enables efficient sampling of criteria weights from a space formed by restricting a simplex with arbitrary linear inequality constraints. In this short communication, we note that the method for...

Generalized analytic network process

Zhu, Bin; Xu, Zeshui; Zhang, Ren; Hong, Mei - In: European Journal of Operational Research 244 (2015) 1, pp. 277-288

The analytic network process (ANP) is a methodology for multi-criteria decision making used to derive priorities of the compared elements in a network hierarchy, where the dependences and feedback within and between the elements can be considered. However, the ANP is limited to the input...

A simulation based approximate dynamic programming approach to multi-class, multi-resource surgical scheduling

Astaraky, Davood; Patrick, Jonathan - In: European Journal of Operational Research 245 (2015) 1, pp. 309-319

This paper presents a model and solution methodology for scheduling patients in a multi-class, multi-resource surgical system. Specifically, given a master schedule that provides a cyclic breakdown of total OR availability into specific daily allocations to each surgical specialty, the model...
