Vacancy chains, information filters, and interregional migration

Autor: R D MacKinnon, P Rogerson

Publikováno v: Environment and Planning A. 12(6):649-658

An interregional migration model based on vacancy chains, on an intervening-opportunities interaction hypothesis, and incorporating endogenously generated imperfect information flows is developed. Analytical results are determined for the case of per

Controlling Interregional Migration Processes of a Markovian Type

Autor: R. D. MacKinnon

Publikováno v: Environment and Planning A: Economy and Space. 7:781-792

A framework is suggested within which normative modelling strategies can be used to make simple dynamic migration models more relevant to policymakers. A job-vacancy model is explicitly linked to a migration- and population-distribution model. Some s

Nonlinear Programming Approaches to National Settlement System Planning

Autor: Y Evtushenko, R. D. MacKinnon

Publikováno v: Environment and Planning A: Economy and Space. 8:637-653

Three rather aggregate approaches to modelling interregional migration processes within a context of national urban settlement systems are described. General, modified penalty-function methods of nonlinear programming are developed and then adapted f

Interregional migration models with source and interaction information

Autor: P Rogerson, R D MacKinnon

Publikováno v: Environment and Planning A. 14:445-454

The importance of information flows in models of migration are emphasized. In particular, migrants are assumed to react to two types of information about job vacancies. 'Interaction information' may be defined as interpersonal communication between r

Optimal Transportation Networks: A Case Study of Highway Systems

Autor: R. D. MacKinnon, M. J. Hodgson

Publikováno v: Environment and Planning A: Economy and Space. 2:267-284

This paper outlines some combinatorial approaches to the optimal synthesis of transportation networks. As an example, the inter-urban multi-lane highway network of Southern Ontario and Quebec is studied. A number of network-building algorithms are ap
