With the rapid development of sensor and detection technologies, measured data analysis plays an increasingly important role in the design and control of heavy engineering equipment. The paper proposed a method for inverse analysis and modeling based on mass on-site measured data, in which dimensional analysis and data mining techniques were combined. The method was applied to the modeling of the tunneling thrust on shield machines and an explicit expression for thrust prediction was established. Combined with on-site data from a tunneling project in China, the inverse identification of model coefficients was carried out using the multiple regression method. The model residual was analyzed by statistical methods. By comparing the on-site data and the model predicted results in the other two projects with different tunneling conditions, the feasibility of the model was discussed. The work may provide a scientific basis for the rational design and control of shield tunneling machines and also a new way for mass on-site data analysis of complex engineering systems with nonlinear, multivariable, time-varying characteristics.

The Interactive Monitoring and Control (IMaC) methodology is a design methodology for operator interfaces to complex engineering systems. This four-step methodology helps designers tailor human-computer interaction to communicate monitoring and control activity requirements to the operator. This paper presents the methodology and associated design principles as well as the results of an empirical study assessing the effectiveness of a proof-of-concept operator interface. The study found that an interface designed by the IMaC methodology resulted in superior operator performance when compared to a conventional interface.

Construction Works

The article analyzes an efficient method for planning the execution of construction work. Construction companies are looking for ways to reduce the essential factors in executing the construction work project, i.e. cost and time influencing the forthcoming company’s operating results are offered to perform engineering pre-construction activities. Engineering pre-construction is a set of technical, legal, economic, technological and organisational measures that shall ensure a consistent start of construction and a rhythmical organisation of major construction works employing optimum technology. Engineering pre-construction provides great potential for working out rational design solutions with respect to the execution of construction works applying a range of methods for assessing the aforesaid solutions. In this case, mathematical methods play the main role. Mathematical methods enable more effective tackling of the execution issues of construction works as well as developing rational design solutions with respect to the execution of construction works (Janušaitis, Juodis 2001; Juodis, Apanaviciene 2003; Viliuniene, Juodis 2002; Malinauskas, Kalibatas 2005; Viliūnienė, Viliūnas 2005; Viliuniene, Viliunas 2007; Žiogas, Juočiūnas 2005; Janusz, Kapliński 2006; Zavadskas et al. 2009; Šiškina et al. 2009; Medeliene, Ziogas 2010). Practical implementation of such solutions in the course of executing construction works would allow cutting down construction costs and construction time by 15–25% and 16–25% respectively (Viliūnienė, Viliūnas 2005). Besides, the rapid development of computer technology enables both faster preparation of rational design solutions to construction works through the application of mathematical methods and integration thereof into special software packages designed for construction management. Therefore, contractors should realise the significance of engineering pre-construction that is especially important to the execution of expensive large-scale projects. The process of construction execution should be improved applying the project management technique that helps to achieve the set goal within a limited time and with the optimum usage of limited resources. The objective of project management is to plan, organise and control project resources in order to implement the goals of the project. Hence, engineering pre-construction should be considered as an individual construction project stage acting as an engine for planning construction execution, organisation and control, thereby enabling a construction company to focus on profitable results. The article presents the methodology for preparing design solutions to the execution of construction work, which is adapted to handle the practical issues of engineering a pre-construction stage. The execution of complex earth works has been chosen as the subject matter of research.

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.

In complex engineering systems, complexity may arise by design, or as a by-product of the system’s operation. In either case, the root cause of complexity is the same: the unpredictable manner in which interactions among components modify system behavior. Traditionally, two different approaches are used to handle such complexity: (i) a centralized design approach where the impacts of all potential system states and behaviors resulting from design decisions must be accurately modeled; and (ii) an approach based on externally legislating design decisions, which avoid such difficulties, but at the cost of expensive external mechanisms to determine trade-offs among competing design decisions. Our approach is a hybrid of the two approaches, providing a method in which decisions can be reconciled without the need for either detailed interaction models or external mechanisms. A key insight of this approach is that complex system design, undertaken with respect to a variety of design objectives, is fundamentally similar to the multiagent coordination problem, where component decisions and their interactions lead to global behavior. The design of a race car is used as the case study. The results of this paper demonstrate that a team of autonomous agents using a cooperative coevolutionary algorithm can effectively design a Formula racing vehicle.
