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.
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.
