摘要
针对石油工程设计单位的具体情况,提出了CAD资源最佳配置的整数规划模型,并对模型的约束条件及目标函数的含义进行了补充说明。为了求解,结合模型特点,通过分析将原模型转化为线性规划问题,并给出了求解算法。由于计算机性能、价格、可靠性等因素随时间的变化幅度较大,针对价格、折旧年限、计算机出图率、计算机能力利用情况等几个参数的变化进行了敏感性分析。最后,根据模型的求解结果,结合一些石油设计院的实际情况进行了讨论,对工作站、绘图软件的引进与开发、提高单机使用效率、建立网络、人员培训、日常维护等问题阐述了自己的观点。
In accordance with the concrete conditions of the design companies of petroleum industry, CAD resource allocation model for figure planning with the additional description of certain restrained conditions and the implication of objective function. For solution, a method of solution calculation is given through analysis on model characteristics and turning the original model into linear planning. Computers are changing in .large extent with time going by in their functions, cost, reliability etc, for the above reasons, analysis is done on sensitivity according to the cost, depreciation for service life, percentage of drawings by computers, and other factors like the application status etc. And finally discussed in the article is the practical situation of some design companies in petroleum industry with the writers own points of view given on such matters as workstation drawing software introduction and development. increasing efficiency of a single computer , setting up networks, personnel training and periodical maintenence.
