摘要
为了使制造企业能够根据市场需求快速调整组织制造资源,简化生产调度过程,提高生产调度质量,提出了一种基于隐性势场的制造单元构建算法。在满足约束的前提下,建立了以最小加工成本和最优单元负载均衡为目标的基于隐性势场的制造单元构建模型,给出了制造单元的构建方法,并构造了基于隐性势场的设备关联矩阵模型和任务关联矩阵模型。该算法具有模型简单、设计变量少等优点。通过具体实例,验证了该方法的有效性和可行性。
To adjust manufacturing resources rapidly according to the market demand, simplify produc- tion scheduling process and improve scheduling quality, a manufacturing resource organization model based on potential field concept is proposed. Under the condition of constraints satisfaction, the mathe- matical model with the minimum producing cost and optimal load balance as the goals is established based on potential field concept. Then, the conjunction matrix model of machines and the conjunction matrix model of machining routes based on potential field concept are establised. The concrete steps of this proposed algorithm are given. The algorithm has the advantages of simple model and less design variables. Finally, an example is given to demonstrate the validity and feasibility of the proposed algorithm.
