Abstract

The objective of the present work, which was sponsored by the French Ministèrs de l'Industrie, is to save “vulnerable” metals, i.e., those for which supply is uncertain and/or those that have to be imported. The production of alloys at the lowest price from a number of stocks of scrap alloys of various composition and from unalloyed metals has been achieved through the use of a new algorithm built into a computer program. The method differs from the usual linear programming and avoids the shortcomings of the well-known algorithms. Results are given showing the profits foundries can achieve when using this algorithm. Finally, some practical aspects of the introduction of this software in a foundry are presented, with unexpected consequences on the replacement of used-up stocks.
