Parallel assembly sequence planning (PASP) reduces the overall assembly effort and time at the product development stage. Methodological difficulties at framework development and computational issues at their implementation made the PASP complex to achieve. This paper aims to propose a novel stability concept for subassembly detection to minimize the complexities in PASP.,In this research, a heuristic method is developed to identify, represent and implement the stability predicate to perform subassembly detection and assembly sequence planning (ASP) at the further stages. Stability is organized into static, dynamic, enriched and no stability between the mating assembly parts. The combination of parts that possesses higher fitness is promoted to formulate the final solution about PASP.,The results obtained by applying the proposed concept on complex configurations revealed that stability predicate plays a dominant role in valid subassembly detection and final sequence generation further.,The value of the presented study lies in the three types of stability conditions and effective integration to existed ASP method. Unlike the existed heuristics in subassembly detection, the proposed concept identifies the parallel subassemblies during ASP.

一种具有新颖稳定性概念的启发式方法，通过子装配检测执行并行装配序列规划

并行装配顺序规划 (PASP) 减少了产品开发阶段的整体装配工作和时间。框架开发的方法论困难和实施中的计算问题使 PASP 难以实现。本文旨在为子装配检测提出一种新的稳定性概念，以最大限度地降低 PASP 中的复杂性。在本研究中，开发了一种启发式方法来识别、表示和实施稳定性谓词，以执行子装配检测和装配序列规划 (ASP)。进一步的阶段。稳定性被组织成静态、动态、丰富和匹配装配部件之间的非稳定性。将具有较高适应度的部分组合起来，形成关于 PASP 的最终解决方案。将所提出的概念应用于复杂配置所获得的结果表明，稳定性谓词在有效子组件检测和最终序列生成中起主导作用。本研究的价值在于三种类型的稳定性条件以及与现有 ASP 的有效集成方法。与子组件检测中现有的启发式方法不同，所提出的概念在 ASP 期间识别并行子组件。
