2. Aim of the Project This project aims at
using virtual manufacturing applications in the subject area of product design and manufacture
It is proposed to develop teaching and learning materials with integrated case study using multi-media format for illustrating various methods and computer tools in product design and process analysis
Problem based learning activities would be incorporated into the various stages of the project

3. The Digital (Virtual) Factory
A newly established laboratory with world class software and hardware facilities
To provide an interactive, graphical-based discrete event simulation environment for students, researchers to model, develop, experiment, analyze and optimize design and manufacturing processes in a digital (virtual) environment prior to production

6. New Curriculum Under Development
Alongside with the development of the Digital Factory in the Department, a framework of a new 9 credit student centered learning activity titled "Integrated Product and Process Design (IPPD)" has been developed.
The activity based on the "Virtual Factory" concept.
This is to be implemented in the final year of the BEng/MEng course in Industrial and Systems Engineering.

7. Objective
This subject is aimed to integrate the different aspects in the area of product and process design through an integrated problem base learning approach.
The learning activities are carried out in the Digital Factory laboratory, which provides a self learning interactive, flexible and graphic-based digital simulation environment for students to model, develop, experiment, analyze and optimize product design and manufacturing process including plant layout.

8. Teaching and Learning Approach
The subject is conducted with problem based approach.
The student group has to determine the knowledge they need to master in order to complete the task requirements.
The knowledge is arranged as a range of study modules which are available to the students for choosing.
These modules are designed with student-centered nature, with coverage of differing virtual design and manufacturing tools.
A mixture of lectures, briefings, seminars, tutorials, simulation exercises and case studies will be used to deliver the various topics so that students are able to complete the task activities.
At the end each student is required to compile an overall portfolio to illustrate the learning outcomes.

11. Task Activities Product Design Evaluation
Based on the product received, each group of student will apply different types of design analysis tools to evaluate the requirements including functions, quality, assembly so as to dictate the detail specification of the design. Detailed product engineering specification and virtual prototyping of the product are the required task results.

12. Task Activities
Optimization and Design of process, tooling and workplace
This task consists of the detailed evaluation of manufacturing process parameters and tooling design by applying virtual manufacturing tools such as virtual machining, mould flow analysis and plant simulation. Deliverables include detailed process plans and specific design of tooling

14. Case Study - Rapid Product Development
This case study deals the adoption of concurrent engineering can take advantages of information systems to synchronize the data and help to provide a virtual collaboration among the users.
The case example illustrates how the isolated islands of functional unit can be grouped together through the adoption of concurrent engineering concept, thus bringing an integrated view of a company's knowledge sources to an individual's desktop, enabling better decision making by providing immediate access to key business information.
The package is available on a CD with instructions for the students and guidance notes for the teacher.

15. Case Study – Web Integrated Product and Process Planning
This case example is designed to facilitate the real time input from potential customers regarding the kind of product they want, allowing small quantities with dissimilar design of product.
In addition, the case example prototype is going to provide value chain information such as order placement and production logistics.
Such prototype aims at quickly providing the right information to the right place at the right time in the right format throughout the inter-enterprise concurrent engineering processes to facilitate communication, coordination, control and integration of multi-enterprise concurrent product and process development.

16. Self Learning Package - Integrated Design and Planning for Assembly in a Virtual Environment
This package concentrates on the area of design for assembly and virtual analysis.
It includes a set of study guide and notes to help students to get familiarize with the topic.
A case study using software to illustrate the concept of the analysis and typical results obtained including product redesign and improvement directions.
An exercise based on a toy train model has been included and assessment of results are to be discussed.
A number of short multiple choice questions are also available for students' self evaluation in the form of a quiz.
The package has been trial implemented in the last semester and was well accepted by the students.
