Abstract
The invention discloses a method for scheduling mixed production of hardware pliers. Firstly, a process task is allocated to each idle process machine in a workshop according to a time scale, after the task is allocated to one machine, the machine is shielded in a set of idle machines of a corresponding process, and meanwhile a workpiece corresponding to the task is shielded in a set of to-be-processed workpieces of other processes. After the task is accomplished, the shield of the machine in the set of idle machines of the corresponding process is cancelled, meanwhile the shield of the workpiece corresponding to the task in the set of to-be-processed workpieces of other processes is cancelled, and the time consumption of the process is accumulated o the accounted time consumption of the machine. A control system circularly allocates the process task to each machine until all tasks are allocated. By adoption of the optimized scheduling method for adjusting the processing sequence according to the time scale provided by the invention, sorting optimization is executed on the processes, the utilization rate of the existing equipment is improved as much as possible while the sequence of the to-be-processed workpieces is considered, and the cost is lowered.

Step 1）, read the number of each operation machine of workshop, read the species and number of this workpiece to be processed, each
Operation and take that kind workpiece to be processed to be completed；
Step 2）, set up for each operation and deposit the set of its idle machine, to set up its for each operation to be processed
The set of workpiece, to set up it for each operation machine accumulative time-consuming；
Step 3）, the operation machine of a free time is randomly choosed, judge the collection of the workpiece to be processed of the operation machine correspondence operation
Whether be sky, if so, execution step 10 if closing）, otherwise execution step 4）；
Step 4）, select to take maximum workpiece from the set of the workpiece to be processed of the operation machine correspondence operation as the work
The task of sequence machine, and the time-consuming maximum workpiece is removed from the set of the workpiece to be processed；
Step 5）, time-consuming by the time-consuming maximum workpiece be added to the accumulative time-consuming of the operation machine；
Step 6）, the operation machine is shielded from the set of the idle machine of its correspondence operation；
Step 7）, it is for each operation beyond the operation machine correspondence operation, the time-consuming maximum workpiece is to be added at its
Shield in the set of work workpiece；
Step 8）, complete to this after processing of time-consuming maximum workpiece in the operation machine；
Step 8.1）, the operation machine is cancelled into shielding from the set of the idle machine of its correspondence operation；
Step 8.2）, for each operation beyond the operation machine correspondence operation, should at it by the time-consuming maximum workpiece
Cancel shielding in the set of workpiece to be processed；
Step 9）, redirect execution step 3）；
Step 10）, the operation machine is put back to the set of the idle machine of its correspondence operation；
Step 11）, whether the set that its workpiece to be processed is judged for each operation is empty, if each operation is to be processed
The set of workpiece is sky, then execution step 12）；Otherwise execution step 3）；
Step 12）, all processing tasks are all assigned, take each operation machine add up it is time-consuming in maximum for most
Height is time-consuming；
Step 13）, the highest that output device is concentrated takes and each the accumulative of machine takes.
