ABSTRACT This paper presents the results of a study conducted to determine whether unit-oriented construction drawings, which are being developed and used by shipbuilders using modern zone-oriented, or modular, construction techniques, will satisfactorily substitute for system-oriented detailed arrangement drawings in the Navy's life-cycle maintenance management process. The study concluded that modular construction drawings will provide the necessary data in a more usable format, and thus are the preferred approach for the Navy's use. However, the study also identified several additionally needed features that are not now being provided in unit-oriented drawings, but which must be included in order to meet the needs of planning and maintenance activities during the operational life of a ship. A number of other observations about drawing use and maintenance are provided.

Lifecycle Management

Features of the lifecycle management process at an electrical network company are described, including a limited budget of repair programs, availability of legal costs, semantic heterogeneity of the subject area terminology, and a significant amount of accumulated historical data. An electrical network equipment life cycle period can be identified in which the total cost of equipment repairs will in the future exceed its capital replacement by new equipment with similar indicators. This gives grounds for drawing up a repair program and makes it possible to use not only technical, but also the economic and historical data of the production assets management system and the accounting information system. The aim of the study is to make the electrical network equipment life cycle management process more efficient by applying a decision making support system in managing the life cycle of equipment at electrical network companies with taking into account economic indicators. The existing electrical equipment life cycle management procedure based on technical indicators (the technical condition index, failure consequences, and failure probability) is analyzed. The equipment maintenance and repair schedule drawn up according to this procedure often includes equipment with overestimated indicators and entails excessive repair costs. The article presents an algorithm using which it is possible to determine the optimal replacement period for a group of homogeneous equipment at an electric network enterprise based on monitoring the change in the equipment state depending on repair costs. An ontological model of the electrical equipment life cycle management process is developed. A decision making support system in managing the life cycle of electrical network company equipment has been developed, the use of which makes it possible to reduce the costs in considering the electrical network equipment operation for the long-term future.

According to the demand of asset life cycle management on closed-loop management of whole process, and taking the characteristics of asset management in power grid enterprises into consideration, this paper puts forward a MIMS diagnosis model of asset management process based on the concept of life cycle management. Using the MIMS model, this paper analyzes the problems of asset management of power grid enterprises from four dimensions, i.e., management mode, information sharing, decision making mechanism and methods, systems and standards. Finally, some suggestions on process rebuilding of asset life cycle management in power grid enterprises have been brought forward.

Improving the efficiency of life cycle management of capital construction projects using information modeling technologies is one of the important tasks of the construction industry. The paper presents an analysis of accumulated domestic practices, including the legal and regulatory framework, assessing the effectiveness of managing the implementation of investment construction projects and of complex and serial capital construction projects, as well as the life cycle management of especially dangerous technically complex and unique capital construction projects using information modeling technologies, especially capital construction projects, as well as their supporting and using systems, primarily in the nuclear and transport sectors. A review of modern approaches to assessing the effectiveness of life cycle management systems of complex engineering systems in relation to capital construction projects is carried out. The presented material will make it possible to formulate the basic principles and prospects of applying approaches to assessing the effectiveness of the life cycle management system of a capital construction project using information modeling technologies.

The variants of the division of the life cycle of a construction object at the stages adopted in the territory of the Russian Federation, as well as in other countries are considered. Particular attention is paid to the exemplary work plan – "RIBA plan of work", used in England. A feature of this document is its applicability in the information modeling of construction projects (Building information Modeling – BIM). The article presents a structural and logical scheme of the life cycle of a building object and a list of works that are performed using information modeling technology at various stages of the life cycle of the building. The place of information models in the process of determining the service life of the building is shown. On the basis of the considered sources of information, promising directions for the development of the life cycle management system of the construction object (Life Cycle Management) and the development of the regulatory framework in order to improve the use of information modeling in construction are given.
