Algorithm of asset strategic management for EAM solutions
Optimal asset management algorithm within 20-30 years period is proposed for enterprises that have large tangible and intangible assets' fleet including buildings, constructions, facilities, land parcels, constructional projects, equipment units, software systems, data bases, etc. As an optimization criterion a maximum total discounted profit for the period is selected. The development strategy which will be selected must satisfy various constraints, reflecting the requirements of customers, the environment, the regulators, the company's owners and management. These constraints may be financial, technical, market, environmental and other. The entire set of possible projects for the acquisition, construction and commissioning of new assets, renovation and decommissioning of the existing assets, as well as projects for the repair of assets and compliance with restrictions, actions and maintenance works is divided into a collection of specially formed portfolios. Inside, all the elements of the portfolios are ranked. Budgets of formed portfolios serve as control variables. The algorithm involves the generation of variants of long-term development of the enterprise and iterate over them in order to find a maximum of the total discounted profit for the whole period. Variants determine terms of projects' completion for the acquisition and construction of new assets and reconstruction of existing ones. Then they are supplemented by the information about projects and activities of maintenance and repair as well as constraint satisfaction. Each variant is divided into yearly intervals, for which optimal internal supply chain plans are calculated. Feasibility assessment of calculated plans is produced using simulation models, special models, models and methods of predictive analytic. The architecture of the software system that implements the developed algorithm is proposed.
