Abstract
The performance of a company depends on the quality of its strategic decisions but depends also on how those decisions are implemented. Companies are composed of different units that can be geographically distributed with different levels of autonomy and local resources. Due to the complexity of the problem many companies use simulation to analyse the performance of critical sectors based on a number of scenarios. This reality requires new approaches that, taking advantage of existing models enables their integration with new models, facilitate their upgrade and allow a distributed execution. In this work we developed a Framework to integrate distributed agent-based simulators (ABMS) with a mechanism of communication TCP/IP to exchange synchronization messages and business messages based on the OASIS standard. The XML standard format was used for coding of all the messages. The communication mechanism of the Framework was developed in order to benefit from distributed computing.

DISTRIBUTED AGENT BASED SIMULATION FRAMEWORK

Abstract
Industrial companies are faced today with strong competition and fast changing markets. To reduce the risk and evaluate alternatives, simulation is often considered to be an adequate tool. Industrial companies' simulation models must have enough internal detail to be useful but, at the same time, must take into account the external environmental behaviour. Distributed simulation has specific characteristics to allow the integration of these models but its complexity limits its use in industry as stated in the literature. To overcome these difficulties, a framework is proposed, using Agent-based Modelling and Simulation (ABMS) technique and offering communication and synchronization mechanisms, which allow the integration of simulation models in the industrial area. To promote semantic interoperability, a business language is also proposed based on the OASIS Universal Business Language (UBL). To validate the framework a prototype was developed. The experiments made with the prototype shows that a distributed simulation can be more efficient than a single computer simulation as the number of agents increases in the model.
