Refill and Drawdown Rules for Parallel Reservoirs: Quantity and Quality
Paredes, Javier; Lund, Jay - In: Water Resources Management 20 (2006) 3, pp. 359-376
This paper presents two operating rules for the refill and drawdown seasons of reservoirs in parallel for water supply, considering water quality. For the refill season a Linear Programming form of the New York City Rule is developed. Another Linear Programming form based on equalizing the...

A note for “On an inventory model for deteriorating items and time-varying demand”
Chu, Peter; Chen, Patrick S. - In: Mathematical Methods of Operations Research 53 (2001) 2, pp. 297-307
In this technical note we discuss a paper of Benkherouf and Balkhi recently published in Mathematical Methods of Operations Research. They established the model for deteriorating items with increasing demand and proved the uniqueness for the solution of the system of first partial derivatives....

Applying search theory to determine the feasibility of eradicating invasive populations
Cacho, Oscar J.; Hester, Susan; Spring, Daniel - Australian Agricultural and Resource Economics Society … - 2006
The detectability of invasive organisms influences the feasibility of eradicating an infestation. Search theory offers a framework for defining and measuring detectability, taking account of searcher ability, biological factors and the search environment. In this paper, search theory concepts...

Note on supplier-restricted order quantity under temporary price discounts
Chu, Peter; Chen, Patrick; Niu, Thomas - In: Mathematical Methods of Operations Research 58 (2003) 1, pp. 141-147
In this technical note, we consider the optimal replenishment strategies for a continuous review inventory model in which temporary price discounts are offered subject to supplier-obligatory restrictions on the special order quantity. We prove that the minimum inventory level during the on-sale...

Version Spaces and Generalized Monotone Boolean Functions
Bioch, J.C.; Ibaraki, T. - Erasmus Research Institute of Management (ERIM), ERIM … - 2002
We consider generalized monotone functions f: X -- {0,1} defined for an arbitrary binary relation = on X by the property x = y implies f(x) = f(y). These include the standard monotone (or positive) Boolean functions, regular Boolean functions and other interesting functions as special cases. It...
