摘要: 应用扩展矩阵描述并行工艺规划中动态变化的优先关系,通过状态转化构造矩阵的动态生成,通过迭代递进形成扩展过程,主要算法步骤是:①构造约束集合;②在约束集上依据优先准则构造约束矩阵;③生成优先矩阵的扩展行、列向量;④组合扩展优先矩阵.由此,建立了与动态CAD设计交叉并行、逐步完善的工艺优先关系描述方法.

Abstract: The processing precedence relation of the dynamic variations in the concurrent process planning is described with the expansion matrix,which forms the generative process of the matrix with the state transformation and the expansion process with the iterative increment.The main algorithm steps are as follows:1.establishing the constraint set, 2.forming the constraint matrix on the basis of the contraint set, 3.generating the expanded line and column vectors of the precedence matrix, and 4.combining the expanded precedence matrix.Thus,a method with intercrossed concurrent and increasingly iterative perfection for the description of precedence relation in the dynamic CAD design has been worked out.
