A system architecting tool for mechatronic systems design

System architecting in mechatronic systems design is a crucial task to define physical and logical configurations of subsystems and components that realize desired functions and behaviors. Particularly, it is crucial to consider sensor-actuator configurations that control the quality of desired functions. The paper proposes a computer-based tool based on extended Function-Behavior-State (FBS) modeling method that incorporates visualization of geometric information and introduction of an interval-temporal logic. These extensions allow system architects to communicate with experts in different domains and domain experts to conduct domain specific design tasks without having quantitative design information about physical configuration.

Evaluation of scenario-based modularization for lifecycle design

Although modular design is a key technique for lifecycle design, effectiveness of modularity on environmental consciousness is not clear. This paper proposes an evaluation method of modular product from the viewpoint of resource efficiency. First, a product is modularized by applying our modularization method based on its lifecycle scenario. Second, the modular structure is evaluated by assuming that each module goes through preferable lifecycle paths (e.g., upgrading, reuse, and closed-loop recycling) designated by the scenario but unmodularized components go through unpreferable paths. This paper also illustrates a case study in order to discuss effectiveness of the proposed method.

Product modularity for life cycle design

Modular design is an important elemental technique in life cycle design for improving, e.g., maintainability, upgradability, reusability, and recyclability. Appropriate modular structure differs according to applied life cycle options; e.g., while the modular structure for recycling should be based on material kinds, the structure for upgrading should be based on functions to be obsolete. This paper proposes a method for determining modular structure by aggregating various attributes related to a product life cycle and evaluating geometric feasibility of modules. This paper also illustrates the prototype system that implements the proposed method and a case study of a printer.

Maximizing utilization rate of office automation equipment by intraoffice circulation

The utilization rate of products, which indicates the extent to which product functionality has been exhausted, must be improved to increase eco-efficiency of the products. In this paper, we propose an intraoffice circulation model that can increase the utilization rate of office automation equipment. The manufacturer makes a contract with an office to provide the required functionality for a certain period. An office would require machines in each section. In our model, machines are periodically reallocated among the different sections with different user characteristics. The algorithm for optimizing circulation plan is developed using genetic algorithm. The model is applied to the use of copiers installed in a university office. The results verify the effectiveness of our model for reducing the environmental load.

A robust design approach to determination of tolerances of mechanical products

Tolerance specifications of design parameters influence both functional performance and manufacturing cost of products. Product functional performance is usually affected by uncertainties of design parameters, robust design can make product functional performance insensitive to those uncertainties. Based on the robust design method and the cost-tolerance models, a mathematical model has been developed for describing the relationships among functional performance, manufacturing costs, design parameters and tolerances. A new robust optimization method has also been developed to determine tolerances and design parameters simultaneously. This new approach has been used for determining design parameters and tolerances of a coating head of printing machinery.
