This subject is aimed at developing the evaluation subsystem of process plan in the Process Digitalization System. This system is carried on the technology economic assessment of process plan at the early stage of process scheme.
Trough analyzing the structural characteristics of the synchronizer's components,the key parts of lightweight car transmission,this paper researches the technical schedule of these parts,particularly discusses the processing plan of them.
This paper presents an implicit enumeration approach to the selection of an optimum subset of technological processes required to execute a process plan under a sequential (or adaptive) tolerance control strategy.
Using this graphical representation, a model is proposed for selecting the best process plan based on some user defined criterion.
A good process plan would minimize the time wasted on such motion.
Major sources of flexibility are obtained by decoupling process plan models from the model of the factory floor and by using a generic controller.
The system generates both a process plan for production and a classification number based on classification theory.
On the one hand, a globally optimum query processing plan is desirable but its construction is not possible due to the lack of global knowledge of the network.
In such a policy, system status is reviewed at discrete points in time, and at each such point the controller formulates a processing plan for the next review period, based on the queue length vector observed.
A common feature of these approaches is that they all require a separate post-processing plan for each query.
An example of a shared post-processing plan is given in Figure 5.
