In the paper, a computer-supported model of the innovation design is presented, which is based on the synergy of modular function deployment (MFD), theory of inventive problem solving (TIPS, TRIZ) and case-based reasoning (CBR) to assist designer to engage in modularized product design. This approach involves gathering all relevant information about the customer voice and applying this information to drive the design of products or modules. So, it is starting from the MFD-Diagrams and continuing through the technical contradictions matrix in TRIZ during the conceptual design stage of new modules or parts. A CBR system is then adopted to quickly search some similar design cases for the references of inventive problem solving. Last, two reasoning mechanism are fabricated based on Protege and JESS expert tool, and a particular case of bicycle part design is studied through the use of knowledge-based prototype system to prove the effectiveness/efficiency of the computer-supported model. However, it will greatly enhance the competitive capability of companies trying to rapid development of the innovation design.
Automatic shop floor control system in distributed computing context is one of the most important links in Computer Integrated Manufacturing (or CIM) system. For most agent-based manufacturing control systems, a real-time product data available mechanism is not considered. In this paper, an integrated approach of RFID technology and multi-agent system of shot-floor control is presented. The proposed framework uses RFID for tracking products in the system and also for attaching product manufacturing information. This shift from off-line planning systems to on-line control systems will facilitate implementations of real-time scheduling requirement in autonomous manufacturing environment.
A blackboard-based architecture is developed for modular product design for the implementation of concurrent engineering. This proposed approach adopts blackboard-based techniques including blackboard, knowledge sources, agents and control module. The Workflow Automation through Agent-Based Reflective Processes (WARP) approach is used to collect the requirements and to build this model for the product development. This WARP approach entails an agent-based architecture that supports the bottom-up configuration, reconfiguration, and workflow-based services of reusable distributed design for X. Furthermore, a prototype system is created on Java, Jess and Jade platform. A specific case of bicycle part design is studied through the use of prototype system to prove the effectiveness and efficiency of the model. The blackboard-based architecture shows to take lesser time and cost in evolutionary cooperative and concurrent product design. It will greatly enhance the capability of companies to satisfy the diverse customer requirements.
CTC Express is the leading domestic company in delivery service and wants to improve their business efficiency by establishing lean management in the shop floor activities. Lean management is generally adopted by the manufacturing industries as a significant technique to reduce waste and operation costs. This paper investigates the continuous improvement through value stream mapping, begins with describing the current situation and proposes the future condition. Several improvements were implemented in the company such as the transformation of automation process, better result in visual control and standardization processes. The new proposed system has shown being able to reduce the works of loading/unloading and in the same time to increase the performance of material handling in each cycle time.
