High logistics and handling costs prevent the bioenergy industry from making a greater contribution to the present energy market. Therefore, a mathematical model, OPTIMASS, is presented to optimise strategic (e.g. facility location and type) and tactical (e.g. allocation) decisions in all kinds...

The paper assesses the impact of electric-drive vehicles (EDVs) on power system reliability. For this purpose, it introduces direct optimization of reliability indices LOLE (Loss of Load Expectation) and EENS (Expected Energy Not Served). The analysis is performed by the proposed optimization...

Temperature compensation is a notable property of circadian oscillators that indicates the insensitivity of the oscillator system’s period to temperature changes; the underlying mechanism, however, is still unclear. We investigated the influence of protein dimerization and cooperative...

Es wird ein Ansatz und ein Algorithmus zur Lösung von stochastischen Stoppproblemen vorgestellt, der auf einer dualen Formulierung zum klassischen Lösungsansatz für Stoppprobleme mittels Variationsungleichungen basiert. Unter bestimmten Voraussetzungen kann man für diese duale Formulierung...

Includes bibliographical references (leaves 18-20).

CMPL (Coliop Mathematical Programming Language) is a mathematical programming language for modelling linear programming (LP) problems or mixed integer programming (MIP) problems. The CMPL syntax is similar in formulation to the the original mathematical model but also includes syntactic elements...

This study describes the development of bio economic models examining the economic and water quality impact of various proposed policy options in the Upper Waikato catchment. In the first phase nitrogen emissions are determined for representative farming systems using the Overseer nutrient...

This paper treats the problem of setting the inventory level and optimizing the buffer allocation of closed-loop flow lines operating under the constant-work-in-process (CONWIP) protocol. We solve a very large but simple linear program that models an entire simulation run of a closed-loop flow...

Traditional approaches to estimating the potential benefits of water reform, including the introduction of water markets, have relied on short-run models which assume irrigation capital is either fixed or not a constraint on decision making. Other studies have incorporated a long-run decision...

This research employs a non-parametric, fractional, linear programming method, Data Envelopment Analysis to examine the Customer Service Representative resource allocation efficiency of a major Canadian bank’s model. Two DEA models are proposed, (1) to evaluate the Bank’s national branch...
