【摘要】：工程机械的液压管件是工程机械的重要组成部分，其生产计划与调度是液压管件生产企业实施信息化管理的核心。论文结合金城宏达机械有限公司信息系统实施项目，针对目前工程机械液压管件生产企业生产计划与调度的现状，对生产计划编制、产能平衡和生产调度等三个关键问题进行了研究。首先，在分析采用BOM结构编制计划的原理的基础上，建立了编制月生产计划及物料需求计划的数学模型，采用Delphi7.0编程实现了其算法；通过对月生产计划的分解，建立了周生产计划和日排产计划的数学模型，并用生产实例进行了模拟实现。然后，在分析液压管件产品结构工艺特点及制约关系的基础上，提出了车间生产能力和生产负荷的计算公式，同时，结合实际情况，对车间生产能力不足情况下的平衡问题进行了计算和对比研究，提出了较为合理的建议。最后，基于JIT思想建立了液压管件生产调度问题的数学模型，并采用遗传算法进行了求解，为企业生产调度的顺利实施进行了有益探索。根据以上研究成果，采用Delphi7.0编程语言，设计开发了液压管件生产计划与调度原型系统，该系统应用于实际生产，，不仅能有利于建立规范化的管理体系，改善企业生产经营水平，而且对全行业的生产管理也具有一定的借鉴意义和使用价值。
[Abstract]:Hydraulic pipe fittings of construction machinery is an important part of construction machinery, and its production planning and scheduling is the core of information management in hydraulic pipe fittings production enterprises. This paper combines with the information system of Jincheng Hongda Machinery Co., Ltd to implement the project. In view of the present situation of production planning and scheduling in hydraulic pipe fittings manufacturing enterprises of construction machinery, three key problems such as production planning, production capacity balance and production scheduling are studied. First of all, on the basis of analyzing the principle of making plan with BOM structure, the mathematical model of monthly production plan and material requirement plan is established, and its algorithm is realized by Delphi7.0 programming. The mathematical models of weekly production planning and daily production planning are established and simulated with a production example. Then, based on the analysis of the structural characteristics of hydraulic pipe fittings and the restriction relationship, The formula of workshop production capacity and production load is put forward. At the same time, combining with the actual situation, the balance problem under the condition of insufficient workshop production capacity is calculated and compared, and some reasonable suggestions are put forward. Based on the idea of JIT, the mathematical model of production scheduling problem of hydraulic pipe fittings is established, and the genetic algorithm is used to solve the problem, which is beneficial to the smooth implementation of production scheduling in enterprises. According to the above research results, the prototype system of production planning and scheduling of hydraulic pipe fittings is designed and developed by using Delphi7.0 programming language. The system is applied to actual production, which is not only conducive to the establishment of a standardized management system. Improving the level of enterprise production and management, and the whole industry of production management also has certain reference significance and use value.
