If the factory contains a large number of production cells in many departments there can be a pool of Engineering Resources which gives services for productions cells. Another option is that each cell has its own Engineering Resource which means they are operating autonomously like separate islands. This is a typical case when there are one or two production cells in the factory and they are operating in very different applications. In that case engineering resources are embedded in the Production Cell. In principle an engineering resource of one production cell can offer services to other production cells as well. The decision making is distributed in the Isle of Automation. There is a high level controller which takes care of the high level production management. Flexibility in production also sets requirements to the managing and controlling of the island. To use hardware efficiently flexible modular and reconfigurable software must be used at every level to manage the whole system. Modular structure and re-programmable software means that operations and functions of the production cells can easily be configured and used on-line. This approach has several features of Service Oriented Architecture approach in production environment see . Veiga et. al 2007 . Production cell The concept of the Production cell has a layered structure for different response levels. These layers include hardware interfaces real-time control middleware and application layers. The key-functions in the island are adaptation reconfiguration sensing and plug-and-play operations. These functions are operating vertically in the cell see figure 1. Depending on the requirements of the applications the properties operation and status level of these key-functions are defined. They are explained more detailed in chapter . .
