An integrated data collection and analysis framework for remote monitoring and planning of construction operations

Recent advances in data collection and operations analysis techniques have facilitated the process of designing, analyzing, planning, and controlling of engineering processes. Mathematical tools such as graphical models, scheduling techniques, operations research, and simulation have enabled engineers to create models that represent activities, resources, and the environment under which a project is taking place. Traditionally, most simulation paradigms use static or historical data to create computer interpretable representations of real engineering systems. The suitability of this approach for modeling construction operations, however, has always been a challenge since most construction projects are unique in nature as every project is different in design, specifications, methods, and standards. Due to the dynamic nature and complexity of most construction operations, there is a significant need for a methodology that combines the capabilities of traditional modeling of engineering systems and real time field data collection. This paper presents the requirements and applicability of a data-driven modeling framework capable of collecting and manipulating real time field data from construction equipment, creating dynamic 3D visualizations of ongoing engineering activities, and updating the contents of a discrete event simulation model representing the real engineering system. The developed framework can be adopted for use by project decision-makers for short-term project planning and control since the resulting simulation and visualization are completely based on the latest status of project entities.

A four-step model for diagnosing knowledge transfer challenges from operations into engineering design

Knowledge gained from operations can help optimize the design of new installations in terms of system performance, health, and safety. Transferring such knowledge to engineering design teams makes it available for use in projects. However, the transfer involves different challenges. To better understand and identify these challenges, we combine a knowledge transfer model with a work systems model into the development of a conceptual four-step model for knowledge transfer from operations to engineering design. Knowledge transfer implies that the knowledge must be captured, transformed into an engineering design context, transferred to the appropriate individuals, and finally, applied to the design of new facilities. In this paper, we 1) present the development of this model, 2) illustrate its application in an empirical case study in an offshore oil company, and 3) propose a generic diagnostic tool to be applied in companies to diagnose and identify the existing challenges within knowledge transfer from operations to engineering design.Relevance to industryThe proposed diagnostic tool allows for better understanding of design problems to be faced and for developing design solutions that improve health, safety, and production effectiveness. This benefits knowledge management and engineering design professionals in industries with geographically dispersed organizations.

Simultaneous and incremental feature-based multiresolution modeling with feature operations in part design

This paper proposes a new feature-based multiresolution modeling approach that can provide multiresolution representation of dynamically changing CAD models of intermediate design stage. Feature-based multiresolution modeling provides simplified shapes of parts of various levels of detail (LOD) by suppressing the detailed features according to a certain LOD criterion. Unlike previous research having mainly focused on the multiresolution representation of the final design model, our approach can carry out simultaneous and incremental multiresolution representation on the intermediate design models. To implement the system supporting this capability, we developed history-based selective Boolean operations, in which if the order of the Boolean operations for a part is altered, the regions affected by the operations are redefined according to the history of the Boolean operations so that the resultant shape may be the same as the original shape of the part. The system implemented using these operations guarantees a unique and valid shape for each intermediate LOD in the simultaneous multiresolution modeling environment. Since the system provides the designer immediately with various detail levels of the CAD model in any design stage, the design process is expected to be accelerated.
