ABSTRACT
This chapter aims to familiarize students with methodology that used to add the missing character in the spatial/temporal models. Temporal models are derived from time–space functions for a specific region, whereas spatial models are derived from the same time–space functions for a specific time period. The chapter discusses the spatial and temporal characteristics of a system, the certainty of model output, time–space functions and their utility in developing methodology for adding the missing character, and integration methodology and gives an example of an energy model where the integration methodology has been successfully used. The integration methodology requires the design of input and output modules. The input module is designed and implemented for two tasks: data adaptation of inputs and parameters into files or subdirectories for use by the model and processing of adapted data from the file or subdirectory. The output module has to store the model output of a specific period or homogeneous region in a file or subdirectory.
