摘 要 决策支持系统(DSS)的发展为决策者提供了良好的信息处理平台。本课题开发了航材订货决策支持系统。该软件为航材保障部门提供订货决策支持、保障信息统计、保障效益分析、监督管理、考核评价等功能,基本满足了航材领域的业务需求。 航材保障在航空装备的整个寿命周期过程有着举足轻重的作用,它影响到装备的可用性和战备完好性。航材管理的决策过程就是针对航材管理的目标、条件和信息决定行动方案的过程。将决策支持系统应用于航材管理,可将航材管理决策支持系统分为订货分析、订货管理、航材库存、航材供应和战备航材储备等决策支持子系统。 课题主要从可靠性的发展及其基本理论出发,根据航材故障前工作时间的数据,将航材分为可修复器材和不可修复器材,研究器材的可靠性指标,根据建立的航材订货模型作为决策支持的理论依据。进而运用软件工程的一般方法,完成模块分解,确定系统的模块层次结构。根据航材使用部门的基本业务要求和需求分析,对系统结构进行清晰的描述,然后用模块设计、组件技术和多层体系设计,使用Visual C++开发平台,建立航材订货决策支持系统。 可靠性理论、信息技术、物流技术及计算机技术在航材系统得到了广泛的利用,研究符合我国航材保障环境的航材订货决策支持系统,科学合理地制定航材订货计划,对提高我们的航材保障理论应用水平和航材保障的航材使用部门、经济效益具有非常深远的意义。 ABSTRACT The development of DSS, provide a good means of information manage. This thesis designs the DSS of Spare parts Order, which includes five functions, order, information statistics, benefit analysis, operation management. The processes of spare parts management decision-making must calculate the target, conditions and information. This thesis, order analysis, orders management, stock of spare parts, supply of combat spare parts constitute the DSS of Spare parts management. This thesis researches problems of spare parts demand and supply of the training flight in the peacetime. By analyzing failure data from using spot, and applying reliability theory, failure distribution of spare parts is obtained, and two models of ordering spare parts are established, which has the ability of ordering proper spare parts on quantity and variety. In the domain of spare parts management, we use the reliability theory, information technology, material-flow technology and computer technology. Formulating strategy rationally for spare parts order, economize money and improves the level of the army spare parts management.
