本文描述了导致开发WIMS的事件，WIMS是一个基于PC的供水库存维护管理数据库系统。WIMS提供以下功能:库存、预防性维护计划、工单管理、维护历史记录和报告/管理功能。本文接着讨论了通用附加功能，如CAD图形集成和使用WIMS编制报告和文档。综上所述，这些功能构成了一个系统，该系统使用熟悉的技术，以合理的成本，以更适度的规模提供了自动化地图/设施管理系统的大部分功能。 此外，还提供了与WIMS相关的操作技术和评估结果，以及与WIMS使用相关的操作模型和描述。

This paper describes events leading to the development of WIMS, a PC based database system for water distribution inventory maintenance management. WIMS provides the following functions: inventory, preventive maintenance scheduling, work order management, maintenance history, and reporting/administrative functions. The paper goes on to discuss general purpose additions such as CAD graphics integration and use of WIMS to prepare reports and documentation. Taken together, the functions render a system that delivers a substantial part of the function of an automated mapping/facilities management system on a much more modest scale, using familiar technology, at a reasonable cost. Issues relating to the use of WIMS data in operational analysis and capacity analysis are also provided, with detailed descriptions of techniques for preparing system models, allocation of demand and evaluation of results.
