| 1 | Simulation of moving boundary of the reaction shaft in a flash smelting furnace显示文摘As to solve the online monitoring of the inner temperatur e and freezing profile of the reaction shaft of flash smelting furnace, simulation of the wall in the reaction shaft in a flash smelting furnace was made through numerical computation. The computational results are very near the data got in s ite. The error of the moving boundary is approximately 3%, and that of the tempe rature is less than 5%. It is proved that the simulation software is applicable for practice to monitor the temperature and moving boundary inside the hearth on line. Based on a large number of the data computed, the relation between the cha nge of the moving boundary and inner temperature is summarized, and the great in fluence of the cooling system on the forming and stability of the moving boundar y inside the hearth is emphasized, which provide the theoretical bases for optim izing the flash smelting operation. | CHEN Zhuo 1,MEI Chi 1,CHEN Hong-rong 1,MO Jiao 2 (1 Institute on Simulation and Optimization of Pyro-installation, Central Sout h University, Changsha 410083, China 2 Science School, Beijing University of Posts and Telecommunications, Beijing 1 | 2001 | Journal of Central South University2001，13，3： | 3 |
| 2 | A LAGRANGIAN RELAXATION APPROACH FOR SUPPLY CHAIN PLANNING WITH ORDER/SETUP COSTS AND CAPACITY CONSTRAINTS显示文摘A heuristic approach is developed for supply chain planning modeled as multi-item multi-levelcapacitated lot sizing problems. The heuristic combines Lagrangian relaxation (LR) with local search.Different from existing LR approaches that relax capacity constraints and/or inventory balanceconstraints, our approach only relaxes the technical constraints that each 0-1 setup variable must takevalue 1 if its corresponding continuous variable is positive. The relaxed problem is approximatelysolved by using the simplex algorithm for linear programming, while Lagrange multipliers are updatedby using a surrogate subgradient method that ensures the convergence of the dual problem in case ofthe approximate resolution of the relaxed problem. At each iteration, a feasible solution of the originalproblem is constructed from the solution of the relaxed problem. The feasible solution is furtherimproved by a local search that changes the values of two setup variables at each time. By taking theadvantages of a special structure of the lot-sizing problem, the local search can be implemented byusing a modified simplex algorithm, which significantly reduces its computation time. Numericalexperiments show that our approach can find very good solutions for problems of realistic sizes in ashort computation time and is more effective than an existing commercial optimization code. | Haoxun CHEN Chengbin CHUIndustrial System Optimization Laboratory Technology University of Troyes, France | 2003 | Systems Science and Systems Engineering2003，12，1： | 2 |
