Landscape-scale fuel treatments for forest fire hazard reduction potentially produce large quantities of material suitable for biomass energy production. The analytic framework FIA BioSum addresses this situation by developing detailed data on forest conditions and production under alternative fuel treatment prescriptions, and computes haul costs to alternative sites at which forest biomass-bas...

We address the problem of pricing contingent claims written on electricity. The special feature of this paper is to consider contract pricing within a market for power producing plants. Calculating equilibrium prices for this market, we obtain a valuation for electricity contingent claims which is fair in the sense that arbitrage is excluded for capacity and claim trading.

We study the optimal production-inventory-outsourcing policy for a firm with Markovian in-house production capacity that faces independent stochastic demand and has the option to outsource. We find very simple optimal policy forms under fairly reasonable assumptions. In addition, when the capacity Markov process is stochastically monotone, the policy parameters decrease in the firm’s current ca...

In planning and managing production systems, manufacturers have two main strategies for responding to uncertainty: they build inventory to hedge against periods in which the production capacity is not suÆcient to satisfy demand, or they temporarily increase the production capacity by \purchasing" extra capacity. We consider the problem of minimizing the long-run average cost of holding inventor...

In this article, we propose a new way to improve master production schedule (MPS) stability under conditions of finite capacity. The purpose is to optimize product availability and customer service for typical situations encountered in the consumer goods industry. Using a comprehensive MPS model, we conduct a simulation study with experimental design to identify factors having a significant inf...

With the trend of globalization, supply chains are increasingly extended and uncertainties associated with material flow along the supply chain have become a major challenge in the planning process. In this study, we examine the effect of supply uncertainty on dynamically managing a two-stage supply chain under both centralized and decentralized controls. Specifically, the downstream faces dema...

This paper considers the problem of capacity planning and operation of energy grids where the power demands are served from renewable energy sources, such as wind farms, and the transmission network is represented by the High-Voltage Direct Current (HVDC) lines. The principal question considered in this work is whether a risk-averse design of the grid, including the selection of wind farm locat...

Prostasomes are prostate-derived, exosome-like microvesicles that transmit signaling complexes between the acinar epithelial cells of the prostate and sperm cells. The vast majority of prostasomes have a diameter of 30-200 nm, and they are generally surrounded by a classical membrane bilayer. Using a selected proteomic approach, it became increasingly clear that prostasomes harbor distinct subs...

In this paper, we address a strategic planning problem for a three-stage productiondistribution network. The problem under consideration is a singleitem, multi-supplier, multi-producer and multi-distributor production-distribution network with deterministic demand. The objective is to minimize the costs associated with production, transportation and inventory as well as capacity expansion costs...
