i, i=1,2 ..., s;
(4) welding plan is established to need the quantity of various part to be respectively w
i, i=1,2 ..., s;
(5) 0-1 variable a is established
i, i=1,2 ..., s;
（1）
(6) the punching press interim stock of various part is established to be respectively c
i, i=1,2 ..., s;
(7) set various part day inlet amount as day
i, i=1,2 ..., s;
(8) set the punching press analysis of manufacturing capability cycle as
my god;
(9) each number of parts of final production is established to be respectively h
i, i=1,2 ..., s;
(10) T.T. of setting effectively work every day as
;
(11) different model is selected according to different demand:
When considering that punching press production capacity is maximum, then utilize as drag;
（2）
When considering that man-hour is minimum, then utilize as drag;
（3）
When considering stamping machine quantity, little stamping machine, the greatly quantity of stamping machine is needed to be respectively m in part, s-m, part is sorted, front m might as well be established to use little stamping machine and be numbered i, rear s-m uses large stamping machine and is numbered j, will use large stamping machine, then utilize as drag when little stamping machine is not enough;
（4）
(12) actual punching production situation every day is exported;
(13) punching press production capacity state is calculated
, wherein,
be then normal production, when
then point out feed;
(14) terminate to calculate.
The present invention can produce following good effect compared with the prior art: the present invention is according to the stroke quantity of part, during presser, weld parts plan, stamping machine characteristic, the key elements such as punching press interim stock, establish punching press production capacity respectively maximum, man-hour is minimum, the production optimization model under service condition optimized by stamping machine, help parts factory client by the punching press analysis of manufacturing capability, safeguard from manual account, change into model calculation scheduling, automatic compiling often plants the processing situation of part and the situation that feeds intake, the flexible management of the class's of realization product plan, improve science and the enforceability of production schedule layout, parts factory staff planners are liberated originally because of the time of manual operation and service interaction 80%, very large help is brought to the post optimum management of client inside.
