Task process timeliness dominating method for information system engineering

Abstract

The invention discloses a task flow timeliness dominating method for information system engineering, which comprises the following steps of: constructing a task flow optimization model for an information system engineering information processing timeliness optimization problem, constructing a typical task flow in the model, introducing a time window to represent user satisfaction, decomposing information processing timeliness so as to minimize the total timeliness composed of fixed time, transportation time and loss time in a user satisfaction range. The method is close to an actual engineering application scene, considers uncertain factors in a flow execution process, performs classification dominance, proposes a new dynamic dominance model based on system engineering application timeliness, shows objective and actual flow timeliness influence factors for system flow execution, and an auxiliary function is provided for reasonable analysis and system flow planning of system designers.

Description

technical field [0001] The invention relates to the technical field of information system construction and application, in particular to a method for making task flow timeliness explicit in information system engineering. Background technique [0002] System generally refers to the integration of multi-category and multi-level heterogeneous systems that form a network according to task requirements. In the actual system-level engineering application process, it is necessary to use the task goal as a logical guide to construct the optimal task process under the condition of resource constraints. [0003] In information system engineering, information needs to be processed and transmitted within the system that undertakes business nodes, and also needs to be processed and transmitted at the physical level of each business node that supports the realization of system tasks. Process timeliness is a very important constraint in the process of system application. Under the premis...

[0005] At present, the information processing process optimization of the conventional information system mainly focuses on theoretical optimization within the process link itself. Although the traditional task decomposition method can intuitively see the deconstruction of the task process, the dynamic coupling relationship between them cannot be well described. Only a static task flow model can be obtained. In most cases, the hidden timeliness factor is attributed to the objective environment state, which
