Modular design and improvement of the management system in the smart home with the use of interval multiset estimates

The paper addresses modular design and improvement/extension of the management system in the smart home and the building automation system (BAS). The design procedure is based on the hierarchical morphological multicriteria design (HMMD) approach: (a) construction of a tree-like system model, (b) generation of design alternatives for leaf nodes of the system model, (c) the bottom-up process: (i) selection of design alternatives for system parts/components and (ii) composition of the selected alternatives into a resultant combination. Here, the HMMD approach with interval multiset estimates for design alternatives is used. The system improvement scheme is based on the following: (a) upgrade of the system components (strategy 1), (b) system extension by adding an additional part (strategy 2). The multiple choice problem with interval multiset estimates for improvement operations is used in system improvement procedure. Two basic applied illustrative numerical examples are considered: (1) a modular management system for the smart home and (2) a modular building automation system consisting of four parts.
