Multi-choice mixed integer goal programming optimization for real problems in a sugar and ethanol milling company

Goal Programming (GP) is an important analytical approach devised to solve many realworld problems. The first GP model is known as Weighted Goal Programming (WGP). However, Multi-Choice Aspirations Level (MCAL) problems cannot be solved by current GP techniques. In this paper, we propose a Multi-Choice Mixed Integer Goal Programming model (MCMI-GP) for the aggregate production planning of a Brazilian sugar and ethanol milling company. The MC-MIGP model was based on traditional selection and process methods for the design of lots, representing the production system of sugar, alcohol, molasses and derivatives. The research covers decisions on the agricultural and cutting stages, sugarcane loading and transportation by suppliers and, especially, energy cogeneration decisions; that is, the choice of production process, including storage stages and distribution. The MCMIGP allows decision-makers to set multiple aspiration levels for their problems in which the more/higher, the better and the less/lower, the better in the aspiration levels are addressed. An application of the proposed model for real problems in a Brazilian sugar and ethanol mill was conducted; producing interesting results that are herein reported and commented upon. Also, it was made a comparison between MCMI GP and WGP models using these real cases. © 2013 Elsevier Inc.

Information technologies in trade facilitation and their use by msmes

This issue of the Bulletin is based on the material presented at the seminar Information Technology for Development of Small and Medium-sized Exporters in East Asia and Latin America, which was held on 23 and 24 November 2004 at the headquarters of ECLAC in Santiago, Chile. The seminar was part of the project entitled Comparative Study on East Asian and Latin American IT Industry, financed by the thematic fund for information and communication technologies (ICT) for development of the United Nations Development Programme (UNDP) and has been carried out in close collaboration with the Institute of Developing Economies (IDE), an organization that belongs to the Japanese External Trade Organization (JETRO). This article contains a discussion of the concepts, definitions and standards associated with electronic commerce, as well as the opportunities to be seized and the challenges to be met so that MSMEs can expand their electronic business.
