We study in this paper the optimization of a production system comprising a multi-item single machine. Taking into account the switching-costs, we analyze the optimization of the system in terms of a system of Quasi-Variational-Inequalities (QVI). We study the structure of this QVI system, its solution and numerical methods to solve it.
Catalytic reduction of CO 2 with H 2 was studied on Ni/SiO 2 , Ni 1-x Cu x /SiO 2 (x =0.05-0.9) and Cu/SiO 2 in a closed circulating reaction system in order to obtain a highly active and selective catalyst for CO formation. The yield of CO from CO 2 + H 2 on Cu/SiO 2 was about 60% and its selectivity was 97%...
