Cilj vežbe Cilj studije slučaja je određivanje osnovnih elemenata poslovnog modela na primeru svetske mreže Google

Poslovni model Poslovni model opisuje kako jedna organizacija kreira, isporučuje ekonomsku, socijalnu i druge vrednosti svojim korisnicima

Poslovni model Poslovni model se može analizirati na više načina Jedan od načina je analiza lanca vrednosti po metodlogiji M. Portera Za razumevanje suštine poslovnog modela analiziraju se elementi glavnog procesa

Lanac vrednosti

Inovacije Invencija je izum, ideja, poboljšanje Inovacija (uvođenje nečeg novog) predstavlja proces primene invencije u praksu Osnovne vrste inovacija (Izvor OEBS): Inovacije proizvoda Inovacije procesa Marketing inovacije Organizaciona inovacija

Zadaci Pažljivo pročitajte tekst nekoliko puta Hronološki složite najznačajnije činjenice Koje su lične karakteristike osnivača Google? Koji su ključni elementi poslovnog modela? Navedite primenjene inovacije? Kojoj grupi inovacija pripadaju?

Introduction Three objectives for a useful flood risk map visualisation tool: Aggregate information in a form that can be assimilated and queried by the end user Provide sensory stimulus and user interaction to aid understanding of unfamiliar concepts Produce a modular unit that can function as the target for disparate model results within broader web/GIS environments –encourage code/API standardisation

Information aggregation Spatial modelling studies produce large amounts of data. A 2D inundation study becomes 3D when considering velocity which becomes 4D when considering uncertainty. We need to aggregate the information. Client and server approach: database (PostgreSQL, mySQL) + scripting (PHP, pearl) Central data store, secure, probably the right way to go Slower, more complicated, needs administering Local storage approach: save data on local machine (matlab file, CSV) + associated data processing program (matlab, R) Fast and independent Only suitable for small scale applications

User interaction Once the data is stored, there must be some method for the user to interact with it Static interaction (GIS) An experienced user can retrieve, act on and plot probabilistic inundation data and map backdrops producing high quality analysis and visual results Steep learning curve Dynamic interaction (matlab, Google maps+DHTML) Familiar ‘widgets’ such as a slider can be used to dynamically query the underlying data base –intuitive user experience Limited to the functionality provided by the application designer

Modularity and standardisation In general, each risk map study produces data in an ad-hoc format depending on the preferences of the programmer. Instead, it would be nice to have a standard format for output to work towards. If widely adopted, a visualisation tool could supply: A set of standard requirements for source data eg., attribute table headings Documentation for the georeferencing format and extent of the study site eg., a bounding box in a standard coordinate reference frame In return, the visualisation tool should comply with external standards such as those of the Google maps API if used

Examples (matlab) Matlab graphic user interface interactive visualisation tool using results produced by Neil Hunter (JBA) for Mexborough (S. Yorkshire UK) Local data storage General interface: third party risk map study provides inundation probability data matrix and background image – program does the rest Interface includes: Slider for probability selection Point and click marker for single location query Popup menu for return period/depth scenario Depth probability figure dynamically linked to point marker
