Consistency of the Measure of Modularity for Disassembly Evaluation of Industrial Products

抄録

Improved measures of modularity developed recently for re-designing the module structures are shown. The main point is to keep the consistency of the measure. The latest version is adaptable to the various combinations of components. When new model of product is planned by mechanical design of today, the quantitative assessment of design is very important. The measure of modularity provides us the quantitative indicator to improve their design for keeping good environment by reducing of materials, reusing of used parts and recycling of resources. The calculation of measure is based upon the state of common properties among product components taking numerical weight factors into account. Their common properties can be selected flexibly depending on social demands as well as maker or user demands. The application study to a coffee drip maker has been demonstrated.
