Multi-core model
The multi-core model by Chauncy Harris and Edward Ullman from 1945 is one of the classic models of urban development , along with the ring model or circular model by Ernest Burgess (1925/1929) and the sector model by Homer Hoyt (1939) . Unlike their predecessors, Harris and Ullman assume that the larger the city, the larger the number of its cores. While Hoyt and Burgess defined the city center as the only core of a city , in the multi-core model peripheral business centers (e.g. shopping centers ), cultural centers or parks are also viewed as such. The different cores of a city are usually characterized by different uses and vary in size and importance.
On the basis of his assumption that a city has several areas of central local functions, this model does justice to reality more than that of Burgess and Hoyt. However, it is criticized that Harris and Ullman did not precisely define the term “core”, which means the city center, in this context.
