"Siam Hitachi Automotive Products" was founded in 1971, located at Samut Prakan province, with a professional license of SAP ST/ALT Production. It has been renamed to "Siam Hitachi Automotive System" in 2013. The business has been operated for over 47 years.


THE challenge:

Siam Hitachi is an important supplier of ISUZU, NISSAN, FUJISAN and FORD, etc. They produce vacuum pumps, alternators, starters, electric throttle bodies, shutter valves and intake manifolds. As a supporting factory of the automobile manufacturing chain, these were the problems they were facing.

  • Their customers created material purchasing plans according to their own master production plan, they then published the purchase & forecast order online, which would be used by Hitachi Automotive in to deliver their orders ontime. Hitachi had to download the plan with 3 days confirmed order + 2 weeks forecast order and import it into their ERP system on time. They also had to adjust factory capacity, production and purchase plan based on customer's plan in real time.
  • Their customers had lots of rules for product barcoding and lot numbers, the same components had different barcode and lot formats, and everything needed to be customized in our barcode system to meet customers’ requirements, this required custom development.
  • They needed to package the product according to the customer's transport specifications. And they also needed to cooperate with the customer's production shift to dispatch the products 3 times a day (By 9, 15 and 24 O’clock), all had to be delivered to customer’s warehouse at the specified time.
  • A system was needed to track the whole process of material purchase, production and quality inspection, one of the key features was the ability to synchronize everything into their ERP system, this also was needed for product tracking and recalls.

The Solution

JUSTPRO's tailored solution JUST-FMS(Forecast Management System)handles the actual needs of the upstream company. Based on three days + 2 weeks mode, it uploads the confirmed order in coming three days and next two weeks forecast into JUSTPRO-MES system through JUST-EDI function. And it does the requirement calculation on time to re-create the WIP and purchasing schedules. Which increases inventory turnover and reduce inventory costs.

JUST-Barcode was used to simplify the factory business, a custom module developed by JUSTPRO called the barcode configurator is used to generate FG's barcode automatically according to different customer’s rules. Each batch of FG's quality inspection information is recorded into the JUST-Barcode system by using 'scan to inspect' which uses a unique identifier for product tracking, all of this is synchronized into ERP.

JUST-Barcode's tracking information is synchronized into ERP system in real time, this includes material preparation, manufacturing, W/H receipt, transfers and much more, and all of these are posted into their ERP's finance modules automatically.
