VISUAL SLAM & AWESIM The computer simulation software package that we use is called Visual SLAM. “Visual SLAM supports the modeling of systems from diverse points of view through a graphical based interface. AweSIM is a simulation problem-solving environment for Visual SLAM. AweSIM provides a database, project maintainer, interactive execution environment, standard textual and graphical reports and concurrent and post process animation facilities.”

SIMULATION… • Simulation Modelling can be Applied to the Whole Life Cycle of a Typical Industrial Systems Project. • Probably one of the most important advantages of simulation modelling is its adaptability. It can be easily applied concurrently to all project stages as the project evolves. The stages usually involve (i) concept design, (ii) detailed design, (iii) implementation, and (iv) operation. Using simulation models developed concurrently with each stage we can: • understand basic system operation at the concept design level, • select the best concept to proceed with to the detailed design, • test all proposed operating and control procedures, • test the impact of all design changes made during the implementation stage, • test the impact of all proposed changes during the operation stage, • predict necessary changes in the system operation to follow the envisaged changes in the external and internal environments of the system
SIMULATION… • Do not simulate when: • the problem can be solved using common sense analysis, • the problem can be solved analytically, • it's easier to change or perform direct experiment on the real system, • the cost of the simulation exceeds possible savings, • there are not proper resources available for the project, • there is not enough time for the model results to be useful, • there is no data - not even estimates, • the model can not be verified or validated, • project expectations can not be met, • the system's behaviour is too complex or can't be defined.

Concurrent Engineering (CE) has been described as(IDA Report 1988): “a systematic approach to the integrated design of products and their related processes, including manufacture and support. This approach is intended to cause the developers from the outset, to consider all elements of the product life cycle from conception through disposal, including quality, cost, schedule and user requirements.”
CE BENEFITS: US DEPARTMENT OF DEFENCE • Engineering Change Orders reduced by 50% or greater. • Product development cycle time reduced 40-60%. • Cost to Manufacture reduced 30-40%. • Rework and scrap reduced by up to 75%.
KEY FEATURES OF CE: • Cross-Functional Teams (CFT’s) • Concurrent Product Realisation Process Activities • Incremental Information Sharing and Use • Design for “X” (DFX) • Integrated Project Management • Early and Continual Supplier Involvement • Early and Continual Customer Focus
THE MAIN ELEMENTS OF CE MANAGEMENT • COLLABORATION • COMMUNICATION • COORDINATION • CONTROL • INFORMATION DEPENDENT SYSTEM

SOME MAIN CHALLENGES FOR FUTURE RESEARCH: • TRANSFORMATION OF INFORMATION INTO KNOWLEDGE • KNOWLEDGE REPRESENATION (Davis, Davenport, Prusak, Grudzewski, Hejduk, Probst, Takeuchi, Minsky, Boahene, Ditsa, Mitchell, Gonzalez, Pukszta)
Knowledge management is an emerging, interdisciplinary business model dealing with all aspects of knowledge within the context of the firm, including knowledge creation, codification, and sharing, and using these activities to promote learning and innovation. It encompasses both technological tools and organizational routines of which there are a numberof components. These include generating new knowledge; acquiring valuable knowledge from outside sources; using this knowledge in decision making; embedding knowledge in processes, products, and/or services; coding information into documents, databases, and software; facilitating knowledgegrowth; transferring knowledge to other parts of the organization; and measuring the value of knowledge assets and/or the impact of knowledge management.
