These subsystems include M1CS Actuators (1526 units), Edge Sensors (3284 units), Segment Controller & Cabling (SCC) (9080 units), Segment Support Assemblies (SSA) (580 units), and Polished Mirrors (84 units). In addition to production and supply of hardware subsystems, ITCC is also tasked with delivering comprehensive documentation for each component, collectively termed as the End Item Data Package (EIDP). EIDP contains a range of critical documents, including Certificates of Conformance (COC) for raw materials, special processes, and bought-out items (BOI), as well as calibration certificates for all measuring instruments used in inspections, part inspection reports (IR), machine-generated IR, non-conformance reports, assembly logs, etc. All these documents received from vendors, gets reviewed by ITCC before submitting it TIOPO. To streamline EIDP management, ITCC has developed the EIDP Management System (EMS), an online tool that facilitates the upload, review, and tracking of each EIDP document. It automatically verifies IRs against the drawing requirements and flags error. Also the IRs are checked wrt the associated COCs and calibration certificates, indicating any issues with calibration expirations or incorrect COC entries. This helps vendors to catch dimensional non-conformances, typographical mistakes and issues with traceability during submission. EMS also allows ITCC members to review each document with an Accepted/Not Accepted response, streamlining the feedback loop. Once all documents are accepted, ITCC can access the complete EIDP with a single click. This system has decreased the time required for document review by approximately 90% and reduced the error percentage to nearly zero. In this paper I will provide an overview of the India-TMT EMS document flow, various login types, module details, tool performance and future scope. |
