1 Information systems in AEC Žiga Turk Univerza v Ljubljani, Fakulteta za gradbeništvo in geodezijo

2 (2) Outline information system: definition, way of integrated a construction virtual organization information technology vs. information system information systems in the new economy role of information technology in designing

3 (3) core business Construction organization and its environment construction planning design finance accounting competitors customers stockholders authorities suppliers human resources sales and marketing

4 (4) Construction industry: a virtual enterprise contractorsub-contractor owner facility manager information material

5 (5) What are the arrows? information, money –easy to move material, energy –hard to move

6 (6) Information: Bringing the pieces together information sharing, communication inside organisation –collaboration –co-ordination –control –management outside organisation –partnering –integration

7 (7) Information Systems System: regularly interacting or interdependent group of items forming a unified whole [m-w]m-w –political system, postal system, structural system Information system: Interrelated components working together to collect, process, store, disseminate information to support decision making, co-ordination, control, analysis, synthesis and visualisation in an organisation [Laudon]

8 (8) Components of an information system material –users and providers, hardware, netware digital –software, data organisational –agreements, protocols, rules, operating procedures –roles, rights, duties

9 (9) Information systems in the information businesses Traditional IS: –support management –support non-core, non value adding activities IS in the new economy: –information is the product –IS used to make the product, not only to manage or support its production core business construction planning design finance accounting human resources sales and marketing

10 (10) Information Technology, computer science (IT) information systems are implemented using IT Information technology: something which includes equipment, applications, and services that are used by organisations to deliver data, information, and knowledge to individuals and processes The term "computer science" is usually reserved for the more theoretical, academic aspects of computing, while the vaguer terms "information systems" (IS) or "information services" may include more of the human activities and non-computerised business processes like knowledge management. Others say that IT includes computer science. [foldoc]foldoc

11 (11) Information technology: More definitions technologies that deliver data, information and knowledge to individuals or processes [turk] –traditional methods (drawings, speech, p-mail) –electronic methods something which includes equipment, applications, and services that are used by organisations to deliver data, information, and knowledge to individuals and processes (Mentor, 1997)

12 (12) Challenges of IS in AEC: one-of-a-kind products one-of-a-kind process one-of-a-kind group of partners computers are good at repetitive tasks IT pays if it can be applied to many similar problems

13 (13) Further challenges different levels of IT literacy high performance concrete consultant subcontractor generally low IT literacy office programs drafting? internet?? bad environment for technology transfer conservative industry - little innovation of core knowledge life time learning not practiced working on many projects at once, pressing deadlines

14 (14) Information systems in the new economy

15 (15) Construction process has sub processes - types information –design, production planning material –manufacturing, building, transport (financial) –moving money information process material process resources control informationinformation technology human/agent information resources feedback information construction technology and techniques construction product

16 (16) old economy new economy Globalization the freedom and the ease of moving of: –information –money –people and goods freedom: political ease: technical

17 (17) Old economy

18 (18) New economy

19 (19) Pure new economy

20 (20) New economy is information economy the product is information ! information? –you can write it in bits and bytes –you can put it on a CD-ROM movies, music, books, printed media, web sites and also...

21 (21) Information charged material economies example: NIKE –manufacturing cost: 10% example: LEWIS –street price San Francisco: $50 –street price Istanbul: $10 material content is shrinking:

22 (22) Material component is shrinking

23 (23) Information systems for designing Žiga Turk

24 (24) Architecture (engineering) architecture is about designing architecture is an information business what is designing? –designing... the process –design … the result

25 (25) Three theories of designing, three roles of IT research process –designing is search in a predefined set of possible solutions creative process –that predefined set does not exist –designing is in the "aha" moment reflection in action –designing is the conversation with media and community assistant –does the search tool –hopefully does not stand in the way too much –cannot do design media –provides communication channels

26 (26) 1 - What is designing Simon: designing is a process of changing existing situations into preferred ones. how?

27 (27) 1- Traditional view on designing there is a (predefined) space of potential solutions designing is a search in the space of solutions –synthesis – creating alternatives –analysis – evaluating alternatives

28 (28) 1- Computerized support for designing computerized representation of the solution space – of every possible solution – a schema tools to generate/synthesize solutions –manually – by drawing –automatically – using specialized tools tools to evaluate/analyze solutions –structural analysis programs

29 (29) 1- Design is a research process Because it includes experiments such as: –exploration... see what follows –move testing... deliberate action with an end in mind –hypothesis testing... discrimination against competing hypotheses but: scientific research is about finding new general truths design is about transforming one current situation into a preferred one

30 (30) 1- Artificial intelligence computer generates every theoretically possible alternative tests it finds the best SLOW! AI is about optimized search techniques –generating only the better alternatives

31 (31) 2- Alternative view on designing pre-reflective actions, results of throwness into the situation (Heidegger) observation of the problem as a whole The essence of intelligence is to act appropriately when there is no simple pre- definition of the problem or the space of states in which to search for a solution creative design!

32 (32) 2-Computerized support difficult, because: –software predefines a solution set - only certain kinds of designs can be done with a program –software detaches human from the real world, barrier between real world and a person software design issues –software that does not stand in the way between the designer and being in the world –software that does not predefine a solution space –software that does not cause blindness

33 (33) 2-Blindness

34 (34) 3-Third view on designing reflection in action designing is a reflective conversation of the designer with: –the problem (through media such as paper, computer screen) –with co-workers (through media again)

35 (35) 3-Computerized support computer as a medium

36 (36) Role(s) of computer assistant –compyter made design tool –(readiness to hand, computer is like a violin medium –conversation with problem –conversation with social environment

37 (37) Recapitulatio

38 (38) Three theories of designing, three roles of IT research process –designing is search in a predefined set of possible solutions creative process –that predefined set does not exist –designing is in the "aha" moment reflection in action –designing is the conversation with media and community assistant –does the search tool –hopefully does not stand in the way too much –cannot do design media –provides communication channels
