There are many aspects to consider the good assembly model for Thai wooden furniture. The main idea is the assembly can be made in difference ways. As a result, the easy to assemble means the efficiency to produce. The way how to make an assembly need to be considers. The assembly assessment model is evaluated from the assembly’s method, the assembly’s point, the assembly’s direction, the assembly’s difficulty and the assembly’s motion and time. All these assembly criteria needed to be set to make the assembly easier. Also, part’s size and weight and part’s direction can affect the result of the assembly. With these assembly criteria, Thai’s wooden furniture experts are choosing to select sub-criteria and compare all sub-criteria. Then, the Analytic Hierarchy Process (AHP) is used to calculate the weight of each sub-criterion. With the weight of all sub-criteria when the assessors evaluate the way the assembly makes, the overall score is calculated. The higher overall score means a good assembly model. The second idea is because the assembly can be adjustable and changeable, therefore the assembly’s sequence needed to be considered. The sequence assessment model is developed to calculate the assembly time. The sequence assessment model will use assembly relationship chart and AND/OR graph to set up all the assembly sequence from the beginning to the finished furniture. The smaller assembly time shows the good assembly.
