Abstract

The information gap between the enterprise resource planning (ERP) and shop floor has always been a critical problem in a manufacturing organization. Keeping in view this integration problem, a Manufacturing Execution System (MES) complexity has been presented in a MES and ERP framework and then the issue has been tackled using an open .NET framework with Microsoft SQL Server 2000, C# and ASP.NET technologies in a web based application. Using any web browser and intranet/internet, the management of manufacturing control process and its coupling with ERP application could be realized with full support from database for controlling the live and real phenomenon taking place at a various manufacturing plants distributed globally at different geographical locations in distributed manufacturing control (DMC) environment. In the last part, a new supervisory Control paradigm has been proposed with ongoing future work to bring all such tasks to reality. SQL 2000 acting as a relational database plays a critical role between the ERP and shop floor, which keep on updating the management through controlled stored procedures, triggers and alerts. The programming interfacing of C#, ASP.NET and ADO.NET with a blend of delegate and events makes the real time tracking practically happen on the shop floor.
