Design Principles

"Minimize work-in-progress and finished goods inventory through intelligent scheduling and demand-responsive production planning."

Excess inventory ties up capital and can lead to obsolescence or damage. By optimizing production schedules, design and manufacturing firms can improve cash flow, reduce storage costs, and increase overall operational efficiency, leading to greater profitability and competitiveness.

What This Means for Your Design

This research shows that by planning production smarter, companies can make less stuff they have to store, saving money and space, without needing to buy new equipment or hire more people.
