“…Representation of stability using stable relations between each pair of parts is proposed by Smith. 27 Smith proposed representation of assembly connections in matrix format and the connections are categorised into two classes: hard and soft. When two parts are connected by physical connectors, the connection is considered as hard and if two components just maintain their position by surface contact without any physical connection then it is referred to be as soft connection.…”

“…Genetic algorithm (GA) is one of the most commonly used optimisation technique, which has been implemented to address the problem. 23–39 Simulated annealing (SA), ant colony algorithm (ACA) and particle swarm optimisation (PSO) techniques are most used next to GA. 40–52 Several other optimisation techniques also have been found successful in solving assembly sequence planning. 53–64 Most of the times, the formulation of ASG problem is involved with user-defined inputs, which may demand skilful users to operate and the results are dependent on human supplied inputs.…”

Sequence of feasible mechanical assembly operations plays significant role in overall cost optimisation process for manufacturing industry and thus great importance is given to assembly sequence generation from past four decades. Though achieving at least one feasible sequence is focused in the earlier stages of research, the introduction of soft computing techniques attracted the industrial engineers towards cost-effective, optimised assembly sequences to attain economical manufacturing process. The integration of assembly sequence generation methods with computer aided design environment ensures more correctness and flexibility to automate the process. In this paper, a detailed review on various methods, their applications and limitations is presented and well discussed.

“…Methods to obtain interference free matrices from different types of CAD data have been developed by many researchers to test assembly feasibility [8][9][10][11]. Smith used support matrix and assembly connection matrix to determine the stable sub-assemblies [12,13]. Most of the researchers' defined assembly sequence generation problem by considering and ignoring assembly stability.…”

There may be several feasible sequences of assembly operations for assembling a mechanical product. Requirement of fixtures for each assembly sequence are different and hence the assembly lead time. Assembly Sequence Planning (ASP) is the activity of finding sequence (s) of assembly operations which has improved productivity and reduced lead time. Generating such suitable assembly sequence (s) have always been a challenging research area because every product is special in terms of its design characteristics. Significant level of automation has been achieved in ASP but huge efforts are still required to enhance its performance through improvement of the existing algorithms and data structures. Identifying stable configurations between constituent parts of an assembly is one of such important concern to augment ASP. It helps reducing dependence on fixtures by driving the assembly process through more number of stable configuration stages making it economical in time and cost.The purpose of this piece of work is to formulate a method to obtain information rich stability predicate automatically through Computer Aided Design (CAD) interface for a mechanical product.The method is automatic and saves hours of time studying the assembly by a skilled and experienced assembly analyst.
