Define a simulation setting, forecast the state that will reach the Real Estate Market with this setting and analyze the results, is easy task with MUSSA.
The MUSSA software is a computational tool designed to describe, predict, simulate and carry out analysis of the Urban Real estate Market. It has been conceived as an application that not only allows the modeler to perform predictions or simulations of this market, but also, to analyze the large amount and variety of spatialy specific information that characterizes this marketThis is so due to the variety of consumers and real estate offered in this market and to the number of variables that characterize their interaction and, of course, due to the spatialelement of the involved information. Thus, the software allows modelersto satisfy their main necessities of information under a unique computational platform
Using intuitive and interactive windows of dialogue, the MUSSA modeler will be able to:
- Define the scenarios in which is interested to forecast or simulate the Urban Real Estate Market.
- Forecast the state of this market for each scenario.
- Calculate, with a user specified level of aggregation, the variables describing the state of the Urban Real Estate Market.
- Generate statistical and graphical indicators of a limitless amount of indices that describe the Urban Real Estate Market, including those available as standard setting of MUSSA and other self defined by the modeler from the predicted variables. The variables that the user can consider is defining indices correspond to the results of any prediction, or a combination of them for comparison indices, as well as information inputed to MUSSA or inputed directly as external variables.
System Requirments
MUSSA has been designed and implemented for personal computers with the following characteristics:
- Operating System: Windows 95 or Windows NT 4.0 or higher
- RAM Memory: 16 Mb or more
- Space in disc: 100 MB or more
- Screen configuration: Minimum resolution 800 ´ 600 and 16 bits of color.
Scenarios
A Scenario of the Urban Real Estate Market corresponds to a set of parameters and fesaibility conditions that the user can introduce or modify and that MUSSA model requires to carry out a prediction of this market.
The module for Scenario setting provides an intuitive interface so that the user can easily define the variables that he has available to specify a Scenario. The more frequeltly modified variables can be defined and modified einteractively, whereas others, are defineddirectly in files that contain them. Thus, the user will be able to, for example:
- modify the amount of consumers to locate (homes and economic activities) depending on the forecasting year.
- change the regulations affecting the supply of real estate or the free location of activities in the different geographic areas of the city. In the same way, the modeler will be able to introduce or modify subsidies and taxes policies to the real estate market..
- modify the zonal measures of access associated with the urban transport system. These measures are built-in as attributes perceived by the different consumers of the real estate market and can vary by substantial modifications in the infrastructure and operation of the urban transport system.
- introduce information of specific real estate projects. Also, he will be able to completely define or modify the real estate supply in the city.
- change the parameters that define the consumers' behaviour (bids) by location, to represent changes in the patterns of tastes or perceptions of the consumers, subjects to its budgetary restrictions.
Prediction
The prediction module of MUSSA is in charge to find the solution of the problem that defines the state of market equilibrium, which considers the conditions imposed by the user in the specified scenario. This modlue solves a large and complex problem of Non-linear Constrained Optimization , which is solved with a sequence of iterative algorithms specially developed for MUSSA.
Queries
MUSSA provides a module for Queries, which allow modelers to generate graphical representations and basic statistical indicators for a great number of variables. The user will be able to analyze the specified scenario, the input variables, the results of a prediction and other exogenous variables that he is interesting in..
In generatingQueries results special attention has received the graphical representations of the information. Along with traditional graphical statistic, MUSSA has assumed, as a standard, the space representations of the information, like a Geographical information System(GIS).
The set of numerical and graphical instruments made available by MUSSA, allows the user a high understanding and a good analysis level of the Urban Real Estate Market, in a direct and simple way, without leaving the computational work environment that MUSSA provides. However, the user has also tools available to export files, to easily transfer data to other computational applications, and thus, to be able to deepen his analysis of the information.
