The allocation of risks among the contracting parties in a contract is an important decision affecting the project success. Some risks in a project are uncontrollable; these are imposed to a project by external factors. Since contracting parties can neither control nor affect the occurrence of such risks, their allocation to a party would be inequitable. Therefore the cost overrun related to un...

We study provably effective and efficient data reduction for a class of NP-hard graph modification problems based on vertex degree properties. We show fixed-parameter tractability for NP-hard graph completion (that is, edge addition) cases while we show that there is no hope to achieve analogous results for the corresponding vertex or edge deletion versions. Our algorithms are based on transfor...

The study of the competitive outcome associated with two consumers of the same resource, algae, is investigated under asymmetric intraguild interactions and carrying capacities that are a function of resource (algae) availability at any time. The mathematical model is motivated by our understanding of the interactions of genus Protoperidinium (toxin producing) and Heterocapsa (non-toxic produci...

We study channel coordination policies for products subject to midlife price declines during their short product life cycles. Using a two-period supply chain model consisting of one supplier and one retailer, we identify policies and/or conditions under which the supply chain can be coordinated and a win-win situation can be guaranteed. We also provide algorithms to determine the win-win policy...

1. The following four books are all reviewed together by William Gasarch. Fair Division: From Cake Cutting to Dispute Resolution) , by Brams and Taylor, Cake Cutting: Be Fair if You Can by Robertson and Webb, The Win-Win Solution by Brams and Taylor, and Fair Allocation (Proceedings of Symposia in Applied Mathematics, Vol 33) Edited by H. Peyton Young. These books all deal with the problem of f...
