Lăzăroiu, Spiru Haret University, Bucharest, Romania The theory that we shall seek to elaborate here puts considerable emphasis on technological features of China’s steel production, its emergence as the world’s most significant steel producer and main manufact...

The present work proposes new heuristics and algorithms for the 3D Cutting and Packing class of problems. Specifically the cutting stock problem and a real-world application from the retail steel distribution industry are addressed. The problem being addressed for the retail steel distribution industry is the retail steel cutting problem, which is how to cut steel in order to satisfy the custom...

Rapid development of automotive industry brings also increased requirements for sheets properties, involving relatively high strength and good formability together with excellent corrosion resistance. Increasing requests for corrosion resistance lead to the production of coated car parts, protected mainly by zinc coatings. Whereas, majority of European producers of passenger cars use preferenti...

The industrial plants, beyond subsisting, pursue to be leaders in increasingly competitive and dynamic markets. In this environment, quality management and technological innovation is less a choice than a must. Quality principles, such as those comprised in ISO 9000 standards, recommend companies to make their decisions with a based on facts approach; a policy much easily followed thanks to the...

A new solution for large-scale scheduling in the steelmaking industry, called Finishing Line Scheduling (FLS), is described. FLS in a major steel mill is a task to create production campaigns (specific production runs) for steel coils on four continuous processes for a one-month horizon. Two process flows are involved in FLS, and the balancing of the two process flows requires resolving conflic...

Located in Guangxi Province, China, the Liuzhou Iron and Steel Company is one of China’s leading suppliers of plate steel to its shipbuilding industry. Also exporting to countries such as Japan, Germany, Singapore and Thailand, the company is now capable of producing one million tons of steel per year, owing to a series of recent technical innovation projects. Foremost among these is an ongoing...

This report is an e ort to consolidate two di erent avors of a surplus inventory matching problem encountered in the steel industry: Surplus Un nished Inventory Matching, and Surplus Finished Inventory Matching. This report is compiled from two other reports that describe the heuristic solution approaches developed for a real world application of these problems [1, 2]. The focus here is to moti...
