A script for calculating temporal availability of educational organizations

The service-oriented approach is actively developing nowadays. While solving complex problem, the need for service composition often arises. The composition is a set of interactions between several services. Geoportal of SB RAS Institute of System Dynamics and Control Theory proposes to define service compositions as JavaScript programs. When implementing the composition, its services are parallelized in order to minimize the overall time for composition execution. This process is stable to the changes that occur in the computational environment. We propose to solve the problem of calculating the temporal availability of educational institutions. To solve the problem we have developed the services for data processing and performing direct calculations, defined the composition services as a JavaScript program. The process of script execution is presented, as well as the reaction of Geoportal to environment changes, the results and features of planning execution of the script.
