Based on no-preemptive priority queuing network model,new infinitesimal perturbation analysis schemes were presented to estimate the dynamic time performance of DMS based on Common Ojbect Request Broker Architecture(CORBA) and Dimensional Measurement Interface Standard(DMIS).

Considering mathematical strictness of measure definition, the time performance measure of multitarget-multisensor data fusion is defined from probability aspect.

A method was proposed to optimize those aspects in order to improve the workflow time performance with cost constraint.

This paper,having gained experimental data of six internal sorting order algorithms by experiments,analyzes the average time performance of the six sorting order algorithms so as to provide the experimental reference for choosing proper sorting order algorithm in the practice.
