This paper reports on early work and concept development for Optimal Mine Site Energy Supply, where the specific energy supply requirements and constraints for mineral production operations are considered against methodologies that have been applied for other sectors and in other energy policy...

The focus of this paper is on the demonstration that some rather well-known network-based formulation in operations research, that have heretofore largely gone unnoticed in activity-based travel research, offer a potentially powerful technique for advancing the general development of the...

This paper presents a disjunctive mathematical model for the optimal design of air cooled heat exchangers. The model involves seven discrete decisions which are related to the selection of the type of the finned tube, number of tube rows, number of tube per row, number of passes, fins per unit...

In the past two decades, the globalization of financial markets and multinational trade has intensified internationally, and become increasingly competitive. In the construction industry, critical changes are initiated to reduce operating costs for achieving sustainable operation. Conventional...

The production of transportation fuels from the conversion of biomass into gasoline and diesel in a bio-refinery is an attractive, clean, carbon neutral and sustainable process. The investment cost for the commercial application of a stand-alone bio-refinery may be reduced via integration with...

ACRE is an Agro-eConomic model for agricultural pRoduction on rEgional level. Based on an extension of Positive Mathematical Programming (PMP) this model was developed as a decision tool for politics with respect to questions of global change scenarios. The validity of the theoretical approach...

Penalty function is an important tool in solving many constrained optimization problems in areas such as industrial design and management. In this paper, we study exactness and algorithm of an objective penalty function for inequality constrained optimization. In terms of exactness, this...

In the paper we model the problem of optimal assignment of respondents to internet questionnaires. The task is taken from a leading online survey company in Central and Eastern Europe which runs several dozen of surveys in parallel. Each survey has a unique respondent inclusion criteria based on...
