This paper will focus on the concept of how to reduce the complexity of connectivity in an integrated manufacturing engineering system using Enterprise Service Bus (ESB) approach. Software platform is developed for designing and implementing the interaction and communication between mutually interacting software subsystems and modules for manufacturing engineering systems. The developed approach enables a manufacturing engineering systems to make use of a comprehensive, flexible and consistent integration and to reduce the complexity of the applications being integrated. The main objective of the current study is to analyse ESB systems and integrate the data and activities considered with products, supply chain and shop-floor management processes.
