Abstract

Previously reported data on the effects of the utilization of coal-based raw materials within the petrochemical industry indicated a conflict between the objectives of efficient utilization of raw materials and energy in structuring an optimum system. The nature of this conflict was examined more closely by comparing system performances which refer to separate considerations of the conflicting objectives. The multiobjective approach was applied in order to generate compromise system structures and to determine the region in which the preferred compromise solution is to be found.

Abstract

Les données publiées sur l'effet de l'utilisation de matières premières à base de charbon dans l'industrie pétrochimique indiquent une discordance entre les objectifs visant (1) l'utilisation efficace des matières premières et (2) l'utilisation de l'énergie lors de la conception d'un système optimal. On a examiné de plus près la nature de cette discordance en comparant les performances de systèmes obtenues avec les deux objectifs précédents. Cette approche à objectifs multiples vise la conception de systèmes compromis et a pour but de déterminer la zone dans laquelle se trouvera la meilleure solution de compromis.
