Biorefineries that plan to use switchgrass exclusively will have to account for year-to-year variability in feedstock production. The objective of this research is to determine the quantity, class, and location of land to lease for switchgrass production to provide for the needs of a...

Two different methodologies are linked to determine the effects of climate change on the Western Cape farm sector in South Africa. First, it uses a general circulation model to model climate change. Second, a sectoral mathematical programming model is used to determine these effects on key...

This research demonstrates the need and the procedure for testing sector programming models It compares the model estimates of endogenous variables to carefully selected base period parameters It uses an operational, static, deterministic, and highly aggregate programming model of Philippine...

A basic model is presented as an expansion of the general location model for optimal organization of an industry operating in spatial markets. Complications are introduced into the model: variations in raw product costs, inventory and carryover (considerations, and multiproduct firms. Recent...

This work develops a bikeway network design model for cycling in urban areas. The objectives of the proposed model are to minimize cyclist risk, maximize cyclist comfort, maximize service coverage for residents, and minimize the impact of the bikeway on existing traffic. The proposed model...

The aim of this paper seeks to introduce the basis of the energy economics models defined as a market equilibrium problems-mixed complementarily problem (MCP). This technique allows the integration of bottom-up programming models of the energy system into top-down general computable equilibrium...

In contact mechanics, a problem might arise when at least one of the contacting bodies is not fully fixed, i.e. the corresponding functional is semicoercive. The paper will deal with numerical methods for these cases. The fundamental Uzawa method for a class of problems does not converge...

Abnormality in human joint biomechanics is the main cause of the degenerative disease development, therefore the description and correction of the joint biomechanics is essential for adequate treatment. We present an approach how to obtain the data of a patient and how to use these data...

The location problem with mobile facilities is motivated by a real-life railway construction project. In railway construction, (im)mobile concrete batching facilities are located to build viaducts and tunnels on a line over a planning horizon. The problem is to determine the number and types of...

We consider resource allocation problems where inputs are allocated to different entities such as activities, projects or departments. In such problems a common goal is achieving a desired balance in the allocation over different categories of the entities. We propose a bi-criteria framework for...
