time, cost and quality are considered as the main components in managing each project. previous researches have mainly focused on the time-cost trade-off problems. recently quality is considered as the most important factor in project�s success, which is influenced by time acceleration that is the less time is spent the more success is gained. in time-cost-quality trade-off problems, each act...

Identifying communities or clusters in networked systems has received much attention across the physical and social sciences. Most of this work focuses on single layer or one-mode networks, including social networks between people or hyperlinks between websites. Multilayer or multi-mode networks, such as affiliation networks linking people to organizations, receive much less attention in this l...

Software component reuse is deemed as an effective technique for managing the growing software complexity of large systems. Software complexity can also be reduced by partitioning the system behavior into different modes. Such a multi-mode system can change behavior by switching between modes under certain circumstances. Integrating component reuse and the multi-mode approach, we have developed...

In this article, a multi-objective function for placement of Distributed Generation (DG) and capacitors with thetap setting of Under Load Tap Changer (ULTC) Transformer is introduced. Most of the recent articles have paidless attention to DG, capacitor placement and ULTC effects in the distribution network simultaneously. Insimulations, a comparison between different modes was carried out with,...

Through detailed analysis of control problem of railway passengerdedicated line intelligent transportation system, a distributed hierarchical control method was proposed by blending the factitious division of hierarchical system and the natural division of distributed control system. This method is based on the hierarchical control theory of large scale system, and includes three levels: the or...

In Civil Infrastructure System (CIS) applications, the requirement of blending synthetic and physical objects distinguishes Augmented Reality (AR) from other visualization technologies in three aspects: (1) it reinforces the connections between people and objects, and promotes engineers’ appreciation about their working context; (2) it allows engineers to perform field tasks with the awareness ...

This report is the last of a series that documents research relating the coupling of spatially and temporally detailed eutrophication models with ecosystem models that lack spatial and temporal resolution. Specifically, the Corps of Engineers Integrated Compartment Water Quality Model, CE-QUAL-ICM (ICM) is coupled to the Ecopath with Ecosim (EWE) fisheries model. This research examines the feas...

This paper describes a methodology that system designers can use to identify, and find suitable responses for, potential failure modes (henceforth called ‘exceptions’) in multi-agent systems.
