P Programming logic
was to go from a manual Gantt showing one week of plant load to the electronic Gantt chart in Preactor. However, Carolina Bacha Head of Quality Control (QC) mentioned that QC was ‘the orphaned son’ of the company’s scheduling. Although QC work should be done in sync with production, it was in reality scheduled intuitively and driven by incessant phone calls. In summary, for Laboratorios Raffo the manufacturing processes (tablet production, primary and secondary packaging) should flow continuously, while the QA/QC processes are undertaken in parallel. The latter are divided into two sets of operations that also flow in parallel.
The Preactor configuration for Laboratorios Raffo, undertaken by SIMLog project leader Gabriel Gaspari and expert developer Mariano Martinez, is highly customised and comprises a Preactor 400 APS system with 7 Preactor viewers. The central objective was to develop a programming logic that would be able to respond to the complexities mentioned above while at the same time allowing the user a simple and intuitive operation of Preactor. This was achieved by a comprehensive team effort including all those who would be using Preactor, from hands-on, day-to-day personnel to those at an IT level that developed the seamless interfaces that allow smooth communication between the existing systems running in Laboratorios Raffo and Preactor.
The first complete scheduling run, including a special development to take into account the initial status of the plant took place in August 2009, less than 8 calendar months from the start. Laboratorios Raffo is now using Preactor
lanning Success story
to assist the managing of its manufacturing environment including its 130 Primary Resources and 150 Secondary Resources. Eduardo Behmer, Laboratorios Raffo’s project leader for Preactor, comments on the success and impact of the implementation. “Preactor is not only a very efficient scheduling tool, it has also been an impressive driving force to improve our logistics chain. Preactor has forced us to re-define the parameters in our MRP Module including the update of the suggested orders the module generates, the update of the raw materials lead times, and other logistics parameters with the objective to improve the starting dates for the production processes. The implementation of Preactor has allowed us a better integration of the supply chain including different areas like Quality, Purchasing, Stores, Production, and Maintenance. We now have a clearer understanding that we are all linked together in the supply chain and have committed to better integrating each area.”
