“…With this method, they performed automatic reasoning by constructing the domain ontology. With the developed tool, they completed the geometric model information's ontology mapping to verify the assembly sequence's feasibility [12]. In more recent research, Dorn et al presented a framework with which they derive an assembly priority graph, dividing the disassembly movement of each part into a pre-and post-planning phase, thus reducing the number of inefficient movements.…”

For the manufacture of significantly repetitive products that require assembly, different strategies have been proposed to improve times, the use of resources, and the reduction of associated costs. For this purpose, there are many documented methodologies that point to method and time studies, reduction of the number of components or the complexity of the assembly as the \acrfull{DFA}, sequence analysis with \acrfull{ASP}, Bourjault, and/or graphs, among others.In the case of products that require to be assembled at the site where they will operate, manufacturing in a fixed position, and of which several assemblies will be performed in different places, the execution of these has been done, almost always, in an intuitive way, that is, solving on the fly, starting from common sense and accumulating parts. The existing literature has limited information on the methods developed for assembly with these characteristics.This study presents a new methodology of sequence generation called \acrfull{CASP} for the on-site installation of a product in which, the criteria and knowledge of a group of engineers are considered, helping to identify the assembly operations, the sequences, the arrangement and allocation of resources and tasks for the development of the assembly.Additionally, this methodology is verified in a case study applied to a photovoltaic charging station, for which a feasible, effective, detailed, and structured assembly sequence was collaboratively generated for the assembly of such a product. The results show the applicability of the \Gls{CASP} methodology and suggest that it could be applied in other complex product assembly contexts requiring on-site assembly.

“…Kumar et al 3 generated an oblique-directional interference matrix (ODIM) by extracting and analyzing the liaison matrix from the assembly, which helps identify the collision-free paths. Qian et al 4 established the relationship between the number of adjacency relations of parts and the assembly priority, used as an important indicator of assembly sequence planning (ASP). Melckenbeeck et al 5 calculated feasibility scores for the assembly step and the optimal assembly sequence by determining the directions in which the contact surfaces between two parts can move.…”

During the assembly design of complex products, the process data management is disordered and the data expression is not standardized, and depends mainly on the experience of technical personnel resulting in a lack of unified data source, low design efficiency, and low automation. This paper proposes a feature-based assembly information model to address these problem, providing standardized original design data for complex product 3D-assembly design. Taking the geometric feature of the mating faces as the study object, the overall structure of complex products and the information requirements of each assembly design stage were analyzed to construct the assembly feature information model. By focusing on the composition and expression form of information in the assembly feature information model, a geometric feature classification criterion applicable to assembly design is presented, and the matching rules of feature pairs, assembly relationship, and assembly constraint instructions are established. Based on these, assembly design information is extracted and expressed in a standardized form. As a validation, the modeling method was conducted on a marine diesel engine cylinder cap as a case study; the performance and applicability of the established rules and the extraction and expression methods were verified through the comparison with the assembly process of the cylinder cap.

The rapid development of today’s smart automobile with increasing functionality and complexity, which results in rising requirement and cost for its troubleshooting service in the after-sales stage. Hence, to keep the firm’s competitive strength, effective design knowledge utilization of automotive created from the task model can promote the feasibility making of a troubleshooting procedure by offering available relationships and semantic scheme of task. The proposed architecture primarily consists of base, field and application three tiers. A formalized representation of ontology, OWL, is used to organize the base filed. The filed tier includes extensional notions and relations for integration of troubleshooting and a criterion repository for verifying solution feasibility, which is depicted in SWRL. In the application tier, a deducing module is generated on the basis of ontology and criterion deduction. To enhance this semantics, in this research, a task modeling and deduction mechanism with feature-intensive ontology are proposed to clearly represent correlative notions for automotive troubleshooting planning (ATP). A criterion-based deducing module on the basis of OWL-DL and SWRL is also applied to specify implied relations through merging deducing modules (DMs) to deal with complex feature data. Eventually, this proposed architecture is examined and verified with an instance relevant to automotive troubleshooting procedure.
