Embodiment Construction

[0061] The invention is a weapon equipment development and decision-making method based on a robust optimization model, the core of which is to construct an objective optimization model considering performance, reliability and life cycle cost. Specific steps are as follows:

[0062] Step 1: Build the objective function

[0063] Robust optimization model is the main method to solve the min-max problem, including the objective function and constraints. The present invention regards equipment performance, reliability and cost as three key design elements and important trade-off objectives.

[0064] Consider the performance element first. A typical performance-based cost model (Performance Based Cost Model, PBCM), equipment cost decomposition can be estimated according to its subsystems, the cost model can be expressed as:

[0065]

[0066] Among them, C k is the cost of the kth subsystem, {p k1 ,...,p km} is the performance index related to the kth subsystem, which is {p...

Abstract

The invention relates to a weapon equipment development decision-making method based on a robust optimization model, which belongs to the technical field of product development cost management and technical management, and is suitable for technical research such as development management of weapon equipment products. According to the method, the defects that a conventional cost-efficiency analysismodel only considers the relationship between the performance and the service life cycle cost and a classic quality cost model only considers the relationship between the reliability and the life cycle cost are made up, and the important method support is provided for the integrated management of the equipment performance, the reliability and the economy. The result obtained through the robust optimization method can achieve the purposes of minimum cost, performance optimization and highest reliability at the same time, the organic unification of the performance, the reliability and the economy of the weapon equipment system is achieved, and a reliable and effective means is provided for the weapon equipment research and decision making.

Description

technical field [0001] The invention relates to a weapon equipment development decision-making method based on a robust optimization model, belongs to the technical field of product development cost management and technology management, and is suitable for technical research such as the development management of weapon equipment products. Background technique [0002] Weapons and equipment are the core foundation of a country's armed forces and an important guarantee for national security. Since the reform and opening up, my country has paid more and more attention to national defense and invested more and more funds. Especially in the context of the intensified arms race among various countries, the competitiveness of equipment is directly related to the national defense security of our country. The military industry undertakes national defense scientific research and production tasks, provides various weapons and equipment development for the national armed forces, and ach...
