Result It showed that tracking error, reaction time, correct rate, category scale, multistage evaluation scale, multi-dimensional scale, latency of P3, inter beat interval , inter respiration interval and blink rate were significantly different among the various tasks. CS,MES and MDS were more sensitive to the total load; ER ,LAT, IBI and IRI were more sensitive to the load of primary task, while RT and CR to that of additional task and BR to the visual load.

These algorithms have laid a foundation for setting up the basic data in MES. The five elements BOM definition used to describe product structure is given in order to reduce BOM quantity and realize BOM consistency effectively. In addition, the mapping algorithm is implemented by five elements BOM, which can make them link seamlessly to transforming from product structure model to procedure model with workflow. It provides a technical foundation to control and management in the product life cycle. And it also meet requirements which include the identicalness, integrality, integration of BOM data in the product life cycle.

Considering the gap between academic research and real world application, the characteristic of manufactories of "much variety and little batch", this paper discusses the abstraction and modeling of the workshop performance using colored Petri net characterizing definite description of DEDS. And rule bases are applied into the model to tackle the dynamic events and disturbances with dynamic scheduling. After analysis on agile response of MES and integration of its scheduling model, by adopting distributed component technology the workshop scheduling model was capsulated as a scheduler to realize the scheduling module of MES easier to be integrated and rapidly reused. Finally a prototype of scheduler is proposed.
