Abstract:
A manufacture system with the abilities of easy reconfiguration and highly scalability becomes flexible, dynamic and open to the use of software technologies. To give these abilities to a manufacture cell formed of three industrial robots and two conveyors, a middleware based on the programming standard Common Object Request Broker Architecture (CORA) was developed, thus creating a distributed manufacture cell, allowing us to have a real production with different final products. In order to optimize the production times of the different products to be manufactured, a product scheduler was developed using the algorithm Earlies Deadline First (EDF) and the support algorithm Deferrable Server (DS). Given that failures may occur on any of the specialized modules of the manufacture system, the self reconfiguration of the manufacture system is something very desirable. This article propose an algorithm to solve this problem, the algorithm identifies the failures in relation to the time it takes the system to make a product, then makes a modification on the working speed of the plant elements of the specialized modules.
