Complexity Analysis of Assembly Systems

Abstract

In today’s market there is a lot of competition. Companies have to respond to the quick market changes in order to keep going with the flow. There is rapid change in the market demand so, in order to cope up with this change the manufacturing and assembly systems of the companies should be so as to respond to these changes. In order to meet the changes manufacturers are making systems that are becoming more and more complex. Complexity is increased due to the addition of parts, replacing the parts or modules with better parts, adding more machines in the operation sequence and more operations, all these things add to the complexity of a system. Complexity leads to more cost, time and it decreases profitability and competitiveness. The objective of this thesis is to analyse the complexity of automatic welding assembly system by adding new information to machine classification codes and, using machine availability as an information content because, machine availability greatly affects the assembly process i.e. whether the machine is available for less period of time or more period of time affects the whole manufacturing and assembly system so graphs are used to analyse the effect of machine availability on machine complexity.
