Practically Feasible Optimal Assembly Sequence Planning with Tool Accessibility

Practically Feasible Optimal Assembly Sequence Plan (PFOASP) achievement is most important for an industrial engineer to meet the demand of producing the final product in less time and cost. A PFOASP directs the industrial engineer to generate a complete product with less number of manipulations from individual parts. An assembly sequence is said to be optimal from its nature of performing parallel operations to form stable subassemblies which directly reduces the overall assembly time for handling large scale products. Most the researchers followed to ignore tool accessibility in their approaches to avoid the computational complexities. However, the generated solution lacks completeness in practice because tools play the significant role while assembling operation. PFOASP determination is most challenging due to validation of multiple feasibilities qualifying criterion. In this paper, an attempt is made to explain the complexity and the importance of tool accessibility consideration in PFOASP with suitable illustrations. A tool based bounding box method is proposed to solve geometrical feasibility in PFOASP.
