A Time-sensitive Explicit Method of Task Process in Information System Engineering

Abstract

The invention discloses a task process timelines explicit method for information system engineering, and constructs a task process optimization model for the timeliness optimization problem of information system engineering information processing. In the model, a typical task process is constructed, and a time window is introduced to represent users Satisfaction, decomposes the timeliness of information processing to achieve the minimum total timeliness consisting of fixed time, transportation time, and loss time within the scope of user satisfaction. The present invention is close to the actual engineering application scene, considers the uncertain factors in the process execution process, and classifies explicit, and proposes a new dynamic explicit model based on system engineering application timeliness, which is the display of system process execution It provides objective and practical process timeliness factors, and provides auxiliary functions for system designers to rationalize analysis and plan system processes.

Description

technical field [0001] The invention relates to the technical field of information system construction and application, in particular to an explicit method of task flow timeliness of information system engineering. Background technique [0002] The system generally refers to the integration of various types and multi-level heterogeneous systems to form a network according to the task requirements. In the actual system-level engineering application process, it is necessary to use the task objective as the 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. The timeliness of the process is a very important constraint in the application of the system. On t...

Problems solved by technology

[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 cannot be quantitatively analyzed for influence, and cannot meet the real requirements of describing the dynamic evolution process of the system and the timeliness of the process execution process.

[0006] Similarly, in the process of traditional process optimization, the optimization is mainly carried out from the perspective of the process designer, with quantifiable index assessment as the purpose of optimization, and the lack of consideration of optimization from the perspective of process service objects
