摘要:
A method and system for determining an array sequence of processing operations to maximize the efficiency of steel plate processing. Between two processing operations, a first sequence constraint based on a first attribute of each processing operation and a second sequence constraint based on a second attribute of each processing operation are defined. A system selects, as a cluster, at least one of processing operations having a common attribute value of the first attribute, and arranged in a sequence satisfying the second sequence constraint. The system regards the first sequence constraint as a sequence constraint between a plurality of clusters, and arranges the plurality of clusters in a sequence maximizing the efficiency of processing.

An outdoor heat exchanger includes tube-outside heat transfer coefficient adjusting means configured to adjust a heat transfer coefficient αo of the outside of a heat transfer tube through which a refrigerant flows, tube-inside heat transfer coefficient adjusting means configured to adjust a heat transfer coefficient αi of the inside of the heat transfer tube through which the refrigerant flows, and heat transfer area adjusting means configured to adjust a heat transfer area A where the refrigerant exchanges heat with a heat medium. A controller controls the heat transfer coefficient αo of the outside of the heat transfer tube, the heat transfer coefficient αi of the inside thereof, and the heat transfer area A to control a heat exchange amount of the outdoor heat exchanger.

A consumable electrode for the production of Nb-Ti alloy is disclosed which is capable of obtaining homogeneous titanium alloy without segregation which contains substantially equal amounts of niobium and titanium. The consumable electrode consists essentially of a compact formed by compressing a uniform mixture of niobium chips and sponge titanium.
