We present a supply chain design problem modeled as a sequence of splitting and combining processes. We formulate the problem as a two-stage stochastic program. The first-stage decisions are strategic location decisions, whereas the second stage consists of operational decisions. The objective...

This study analyses the foreign exchange market disequilibrium in Pakistan. A monetary model of exchange market pressure has been developed and estimated using a VAR model. Employing Granger causality and impulse response analysis, it is shown that monetary authorities in Pakistan have only...

This paper reviews the information available on the impurities encountered in stationary fuel cell systems, their effects on the fuel cells, and the maximum allowable concentrations of select impurities suggested by manufacturers and researchers. A generic model of a molten carbonate fuel...

Planning horizon is a key issue in production planning. Different from previous approaches based on Markov Decision Processes, we study the planning horizon of capacity planning problems within the framework of stochastic programming. We first consider an infinite horizon stochastic capacity...

This paper addresses a multi-period investment problem for selection, acquisition, and allocation of alternative technology choices to meet the demand of a number of product families over a long-range planning horizon. The problem captures the essential features of many existing models for...

In this paper, we consider a class of two-stage stochastic optimization problems arising in the protection of vital arcs in a critical path network. A project is completed after a series of dependent tasks are all finished. We analyze a problem in which task finishing times are uncertain but can...
