Description

A kind of production optimization method of steel member
Technical field
The invention belongs to steel member production management technical field, and in particular to a kind of supervision for improving steel member production efficiency Method.
Background technology
Steel member system has from heavy and light, batch production manufacture, quick for installation, short construction period, anti-seismic performance is good, invests back The comprehensive advantage such as fast, low in the pollution of the environment is received, compared with reinforced concrete structure, is developed with more at " high, big, light " three aspects Unique advantage, in the world, particularly developed countries and regions, steel member obtained in building engineering field rationally, It is widely applied, the demand of steel member is increasing, and its output is also improving year by year, therefore optimizes steel member production, right The producers of steel member are reasonably assessed and distributed particularly significant.It is by timing mostly at present, reckons by the piece, counts tonnage Mode assesses the production efficiency of steel member welder.Some steel members weigh several tons but weld length only has several meters, another A little steel member lighter in weight but weld length is up to tens meters.By timing, reckon by the piece, count tonnage these modes and can not truly comment Estimate the ability level of welder.At present, the real work amount of steel member painter and ability level are the tons with steel member Position is weighed.
It can be seen that either welding or paint, existing production method is all unable to the work of reasonable distribution varying level worker Measure, greatly reduce production efficiency.Therefore, establish it is a set of can rationally assess welding, the production capacity of painter, and according to Method according to welding, the production capacity reasonable distribution workload of painter is particularly significant.
