The course exercises will form part of a mini-project on e.g. how to efficiently collect and make experiences re-usable from the semester 7 building site project.

A major problem today is to efficiently use experiences gathered during a project. Knowledge is stored in persons heads and re-used as these persons are involved in new projects. IT gives us opportunities to create meta knowledge (knowledge about knowledge, who knows what about what?) and also make computer stored knowledge easier accessible. We see everyday examples on mistakes and faults which could have been avoided especially if you are given some hints about where we problems could be expected.

Exercises shall be carried through and may also be part of a mini project.

A potential mini-project would be KMAN2002, knowledge management on the Internet.

KMAN2002 should be available from an optional website through a conventional HTML browser. The following activities will contribute to the building-up of KM2002

• Listing and structuring of building project and building process concepts which can classify possible knowledge domains such as geometric product model descriptions, documents, design process, construction process, building maintenance process, IT tools, etc. (exercise during the 'Application Information Models' session)
• Listing of data used in the proposed system
• categorisation of actors in the experience capture process (user idenfication)
• conceptual layout of a KMAN2002 functionality (which aspects of users work will be supported)
• Work Flow models to describe the actors/roles in the application and what type of messages that are are exchanged.
• Sequence Models describing how sequences of actions are performed for the studied case.
• Artefact Models to which describe artefacts that can/is used (forms, databases, communication spaces, etc.)
• choose of knowledge representations (in this case hypertext and relational database with ASP connection to the WWW)
• continuos implementation of a demonstrator

September 17 2002

	Group Fib16:2121 works on the Limfjord Kollegiet in their semester 7 main project. Focus is on value based management and collaboration during renovation. They would like to analyse existing collaboration experience portal with regard to development over time of collaboration quality. They are also interested in collecting experiences from users of the dwellings (students) to supply information to improve the partnering process used during the Limfjord project.
	Group Fib16:2124 works on a project with COWI on project management with focus on control of the building process. They will identify critical control domains, collect information, make analyses (possibly develop tools to this purpose), implement improved process control routines and evaluate the outcome. The KMAN2002 could well be a database with webaccess to capture process experiences. This database can also be used to supply the analyses tools with appropriate data.
	Group Fib16:2126 works on a project with Stork Vindue, Farsø on optimising the supply chain and especially in connection with transport of windows on lorries to the local distribution dealers. The group mean that a web based database system could be used to capture requirements and wishes from the dealers on deliveries (what and when).

Exercise A on conceptual modelling of KMAN

Use the contextual design method to

• categorisation of actors in the proposed KMAN2002 system (user identification);
• conceptual layout of a KMAN2002 functionality (which aspects of users work will be supported);
• Work Flow models to describe the actors/roles in the application and what type of messages that are are exchanged;
• Sequence Models describing how sequnces of actions are performed for the studied case;
• Artefact Models to which describe artefacts that can/is used (forms, databases, communication spaces, etc.);
• listing of data that may be available and needed to support the system.

Exercise B on building and handling IFC based product models and components

• make a hierarchical decomposition of the building project to appropriate level;
• design a floor with rooms in a Cad system;
• export the model from CAD system A in IFC format and import it to CAD system B;
• Check the consistence of the model after transport.
  
  
• Install the SOLIBRI Model Checker program (delivered at lecture) and check your IFC building model.

Exercise C on database design and web access

• Use the results from previous exercises to make a conceptual design of a relational database serving as (part of) an information container to KMAN2002;
• implement the database using Microsoft Access;
• test database access using the in built possibilities to make forms in Access;
• ----
• implement SQL calls to the database from a web browser environment.

Exercise D on meta structuring of information using XML

• build a XML file of part of the product/component model used in KMAN2002 system.
• manipulate the XML file using the XMLspy program
• propose an appropriate XML output file that can be used to transport data to another application on Internet.
• ------
• extend your web based database application to export xml data;

Exercise E on new services in digital cities and intelligent buildings

• make a sketch on how your KMAN2002 can be supported by services in the digital city
• make a sketch on intelligent building systems may change the design and use of buildings and its related supply chains.
