Lot-base traceability requirements and functionality evaluation for small- to medium-sized enterprises

This paper addressed a data modelling and functionality evaluation of traceability system requirements and its implementation for small- to medium-sized enterprises (SMEs). The major idea is to convert the data structure and system behaviour arising from traceability requirement into modelling using data modelling techniques in a user-friendly and economical way. Then, based on a case study the paper expounds the methodology by implementing the model to a computerised traceability information system. The system can manipulate operation data as well as quality data dynamically to keep the traceability information up to date and useful. The solution responds to all traceability requirements of integrity, data collecting, linking, and guarantees different types of lists and reports in the support of quick decision making with minimal human efforts.
