Inventory models of modern production and service operations should take into consideration possible exogenous failures or the abrupt decline of demand resulting from obsolescence. This article analyzes continuous-review versions of the classical obsolescence problem in inventory theory. We assume a

Abstract
In this paper we develop a simulationβbased approach to stochastic dynamic programming. To solve the Bellman equation we construct Monte Carlo estimates of Qβvalues. Our method is scalable to high dimensions and works in both continuous and discrete state and decision spaces while avoiding discretization errors that plague traditional methods. We provide a geometric convergence rate. We illustrate our methodology with a dynamic stochastic investment problem. Copyright Β© 2011 John Wiley & Sons, Ltd.

We study the integer multiple criteria knapsack problem and propose dynamicprogramming-based approaches to finding all the nondominated solutions. Different and more complex models are discussed, including the binary multiple criteria knapsack problem, problems with more than one constraint, and mul
In this study we present a Web-based interface to a dynamic simulation. The simulation is based on an emulsion polymerization process operated by the Dow Chemical Company. We also describe the software architecture that allows simulation updates to be transmitted dynamically across a network, from a
This paper presents a fuzzy multi-objective linear programming approach to solve the energy allocation problem. For this, nine energy resources and six household end uses are considered. An optimal solution will be extracted, and an explicit interactive sensitivity analysis will be dealt with. As th
In this study, we present a new molecular dynamics program for simulation of complex molecular systems. The program, named ORAC, combines Ε½ . state-of-the-art molecular dynamics MD algorithms with flexibility in handling different types and sizes of molecules. ORAC is intended for simulations of mol
We propose a first approximation to the modeling of cognitive decisions based on the theory of associative memories. The basic structure are the matrix memories of Anderson-Kohonen adapted to include the modulation of associations via tensorial preprocessing of inputs. This view admits an easy imple
