In the JIT assembly system, if any supplier does not deliver the raw materials or components on time, or in the right quantity, the core manufacturers will not assemble on the schedule, which will bring great loss to the whole supply chain and greatly reduce the competitiveness and collaboration of the entire supply chain. Based on a survey on supply chain collaboration and operation model, sup...

In this paper an attempt has been made to determine Economic Load Dispatch (ELD) using Hybrid (FF-DE) and FF techniques. The methods for ELD evaluation are developed considering fuel cost of the system. Economic Load Dispatches are calculated using FF-DE technique without violating the reactive power constraints of the system. Most of the studies related to ELD use traditional methods based on ...

In a distributed environment like the Internet, mobile agents can be employed to perform autonomous tasks such as searching and negotiating. However, for mobile agents to be widely accepted, performance and security issues on their use have to be addressed. In this paper, we propose a parallel dispatch model with secure route structures for protecting the dispatch routes of agents. This model f...

The technical feasibility of a power generation dispatch in competitive electricity markets consists of not having any overloaded equipment, not only in case of normal operating condition, but also when any contingency established in the security criteria occurs. In addition, bus voltages should be within their limits. This paper describes an optimization method to analyze and solve the transmi...

This paper presents two optimizations of the master-slave paradigm which provides more robustness. The former uses a mobile master which randomly jumps from node to node in order to dispatch the bandwidth load during the application execution. The latter aims to fully decentralize the paradigm like peer-to-peer systems. We present and experiment our new schemes on an application dedicated to te...

Carsharing operators, which rent out electric vehicles for minutes or hours, lose money on idle vehicles. We develop a model that allows carsharing operators to offer the storage of these vehicles on operating reserve markets (market for quickly rampable back-up power sources that replace for instance failing power plants). We consider it a dispatch and pricing problem with the tradeoff between...

This paper argues that IT failures diagnosed as errors at the technical or project management level are often mistakenly pointing to symptoms of failure rather than a project’s underlying socio-complexity (complexity resulting from the interactions of people and groups) which is usually the actual source of failure. We propose a novel method that adopts a socio-complexity lens, Stakeholder Impa...

This paper proposes a decentralized approach for the management of distribution systems including dispersed generation. The methodology is zonal approach and multi-agent systems based. The study presented compares centralized and decentralized methods and draws conclusions about the advantages and drawbacks of each.

This paper presents a multi-objective teaching learning algorithm based on decomposition for solving the optimal reactive power dispatch problem (ORPD). The effectiveness and performance of the proposed algorithm are compared with respect to a multi-objective evolutionary algorithm based on decomposition (MOEA/D) and the NSGA-II. A benchmark power system model is used to test the algorithms’ pe...

In this paper we report on our ongoing study of integrated criminal justice systems. Our focus here is on theorizing the nature of and arrangements among the policy issues, operational activities, and technical architectures to support knowledge sharing among personnel and across geographic and organizational boundaries. Here we draw on data from a comparative case study across three sites to r...
