Abstract:
|
A minimum cost spanning tree problem analyzes the way to efficiently
connect individuals to a source when they are located at different places.
Several rules have been defined to solve this problem. Our objective here is
to propose a new approach that differentiates some costs that may deserve
compensations (involuntary costs) from some other connection costs that
may be considered voluntary. We therefore define a solidarity egalitarian
solution, through which, the total cost is allocated by considering pay-backs
to equalize the involuntary costs, thus fulfilling the weak stability condition
of individual rationality.
Keywords: Minimum cost spanning tree, Solidarity, Cost sharing,
Egalitarian
