“…In Busch, the focus of external change was on the implementation of district heating networks, and how different intervention strategies lead to the success or failure of the policy [93]. Others have explored how ABM can realistically capture the independence and coordination of components in earthmoving operations [94], [95].…”

Uncertainty and interconnectedness in complex engineering and engineered systems such as power-grids and telecommunication networks are sources of vulnerability compromising the resilience of these systems. Conditions of uncertainty and interconnectedness change over time and depend on emerging socio-technical contexts, thus conventional methods which can conduct normative, descriptive and prescriptive assessment of complex engineering and engineered systems resilience are limited. This paper brings together contributions of experts in complex engineering and engineered systems who have identified six methods, three each for uncertainty and interconnectedness, which form the foundational methods for knowing complex engineering and engineered systems resilience. The paper has reviewed how these methods contribute to overcoming uncertainty or interconnectedness and how they are implemented using case studies in order to illustrate essential approaches to enhancing resilience. It is hoped that this approach will allow the subject to be quantified and best practice standards to develop.

Creation of One Excavator as an Obstacle in C-Space for Collision Avoidance during Remote Control of the Two Excavators Using Pose Sensors

Many solutions about the teleoperation of unmanned robotic excavators have been studied continuously. However, if excavators that are remotely controlled were employed, the probability of an accident would be higher. For this reason, there have been many ways proposed to attempt to reduce accidents in these dangerous situations. In this paper, a novel methodology will be introduced with a focus on the multiple excavators themselves. The proposed method details how one excavator can be generated or expressed as an obstacle in the Configuration-Space (C-space) with respect to another excavator’s side for collision avoidance each other. This method is based on kinematics information which is measurable and given. Therefore, this method can be used or applied independently by using widely used pose sensors and wireless communication devices. The phase of mathematical derivation about obstacle sets is described in detail. The results are shown in accompanying figures and tables for demonstrating that the proposed method detected the proximity and found the collision-free zone accurately. The proposed system can be powerful when applied to a teleoperation system, where it would be particularly useful and helpful to the operator.

“…Using advanced information technologies in earthwork operations to improve safety and productivity is a major concern for researchers. Vahdatikhaki et al [15] proposed the application of a Multi-Agent System (MAS) as a means to support fleetlevel coordination for earthwork operations. Ontologies are one of the advanced technologies that have been used in construction to facilitate not only the human-to-human but also machine-to-machine communications by formalizing the information exchange scheme [16].…”

Safety in the construction industry remains a major challenge despite the technological advancements made in recent years. In recent years, ontologies are applied to give a formal structure to the knowledge in different domains. Ontologies also facilitate the integration of various domain knowledge and thus allow for better cross-functional developments (e.g., operator support systems that consider safety and productivity at the same time). The authors have previously developed a comprehensive Earthwork Ontology (EW-Onto). However, there has been no linkage between safety regulations and EW-Onto. Therefore, this research aims to: (1) develop a formal representation of earthwork safety regulations knowledge, and (2) integrate this knowledge with EW-Onto. A case study is developed to validate the integrated ontology. It is shown that the integrated ontology can be used to bridge the gap between high-level safety regulations and task-level instructions.
