This study reports on a new approach to the payment scheduling problem. In this approach, the amount and timing of the payments made by the client and received by the contractor are determined so as to achieve an equitable solution. An equitable solution is defined as one where both the contractor and the client deviate from their respective ideal solutions by an equal percentage. The ideal sol...

Developing cooperation in discontinuous s/c relationships: a case study in construction industry Florence CRESPIN and Robert SALLE The aim of this paper is to identify mechanisms at play in the development of cooperation in industries characterized by a high level of purchase discontinuity. The paper concentrates on the construction industry. In the construction industry adversarial relationshi...

Interval-based methods can approximate all the real solutions of a system of equations and inequalities. The Box interval constraint propagation algorithm enforces Box consistency. Its main procedure BoxNarrow handles one function f corresponding to the revised constraint, and one variable x, replacing the other variables of f by their current intervals. This paper proposes an improved BoxNarro...
