On Preparing Offers for Targeted Development Programs in Housing and Communal Services

摘要

The article offers a mathematic development model for economically sound and close to optimum park of technical facilities used in housing and communal services, that implies purchasing new samples of these facilities and upgrade items already existing that have quite low level of technical perfection. A level of technical perfection of the item is a complex (integral) characteristic that relies on the system of indexes that describe its main properties, based on its purpose, and is reflective of its technical progressiveness. Level of technical perfection of the park is a mean weighted sum of technical perfection parameters for all the items in the park. The model is based on algorithm for presentation of technical facilities development park and is made as a standard task of linear programming, solution methods with limitations in the form of equalities and inequalities, including methods of integer linear programming. The criterion used is an indicator that characterize reduction of degradation, a value inverse to the technical perfection level. The author analysed economic expediency of combined purchases and upgrades for various types of technical facilities under various amounts of financing. The article presents results of mathematic model approbation.
