Balance capacity and reduce setup time

Does your manufacturing facility run products on shared equipment? Are you using static lot, batch, and/or campaign sizes with Economic Order Quantity (EOQ) or manual rule-of-thumbs? Are you looking to understand your operations true capacity to get through the product wheel? If these challenges sound familiar, you may have a lot size optimization problem, and we can help.

Lot Sizer Software Module

Invisitcs’ Lot Sizer software uses advanced operational research mathematics to calculate the sweet spot between changeover costs, inventory costs, and customer service in order to provide the optimal lot sizes for your production. Leveraging the Invistics methodology which blends proven Lean principles adapted to high-mix environments with key components of Six Sigma, Lot Sizer recommends a set of optimal lot sizes, batch sizes, campaign sizes, and/or order quantities that will minimize the overall costs in your plant or supply chain. These results can then be fed back into your information systems to enable better planning and scheduling.

The Lot Sizer software was funded by the National Science Foundation, based on years of research in collaboration with professors from Massachusetts Institute of Technology, Georgia Institute of Technology, and others. It is a “bolt-on” module that can feed directly into a variety of ERP systems such as SAP, JD Edwards, Oracle, and so on, with a minimal investment in IT resources.
