Purpose

During the design of a new product, the generation of assembly sequences plans (ASPs) has become one of the most important problems taken into account by researchers. In fact, a good mounting order allows the time decrease of the assembly process which leads to the reduction of production costs. In this context, researchers developed several methods to generate and optimize ASP based on various criteria. Although this paper aims to improve the quality of ASP it is necessary to increase the number of criteria which must be taken into account when generating ASPs.

Design/methodology/approach

In this paper, an ASP generation approach, which is based on three main algorithms, is proposed. The first one generates a set of assembly sequences based on stability criteria. The obtained results are treated by the second algorithm which is based on assembly tools (ATs) workspace criterion. An illustrative example is used to explain the different steps of this proposed approach. Moreover, a comparative study is done to highlight its advantages.

Findings

The proposed algorithm verifies, for each assembly sequence, the minimal required workspace of used AT and eliminates the ASPs non-respecting this criterion. Finally, the remaining assembly sequences are treated by the third algorithm to reduce the AT change during the mounting operation.

Originality/value

The proposed approach introduces the concept of AT workspace to simulate and select ASPs that respect this criterion. The dynamic interference process allows the eventual collision detection between tool and component and avoids it. The proposed approach reduces the AT change during the mounting operations.

装配计划生成的工具工作区考虑

目的

在新产品设计过程中，装配序列计划（ASP）的生成已成为研究人员考虑的最重要的问题之一。事实上，良好的安装顺序可以减少组装过程的时间，从而降低生产成本。在这种情况下，研究人员开发了多种方法来根据各种标准生成和优化 ASP。尽管本文旨在提高 ASP 的质量，但有必要增加生成 ASP 时必须考虑的标准数量。

设计/方法/方法

在本文中，提出了一种基于三种主要算法的 ASP 生成方法。第一个基于稳定性标准生成一组装配序列。获得的结果由基于装配工具（ATs）工作空间准则的第二算法处理。一个说明性的例子被用来解释这个提议的方法的不同步骤。此外，还进行了比较研究以突出其优势。

发现

所提出的算法针对每个装配序列验证所用 AT 所需的最小工作空间，并消除不遵守此标准的 ASP。最后，剩余的装配序列由第三种算法处理，以减少安装操作期间的 AT 变化。

原创性/价值

所提出的方法引入了 AT 工作区的概念来模拟和选择符合此标准的 ASP。动态干涉过程允许工具和组件之间的最终碰撞检测并避免它。所提出的方法减少了安装操作期间的 AT 变化。
