Optimizing Product-Site Qualifications in Western Digital’s Supply Network

Western Digital Corporation (WDC) designs, develops, and manufactures a broad range of data storage products. Before any of these products can be manufactured, they must first be qualified at one or more manufacturing sites (qualifying a product is a time-consuming process that ensures that a site is capable of manufacturing the product in accordance with all quality requirements). Although expensive, qualifying a product at multiple sites increases the likelihood that 1) demand can be met for a reasonably broad range of demand scenarios while 2) satisfying site capacity constraints and 3) attempting to meet minimum site-utilization targets. This talk describes an optimization algorithm used by WDC to find a balance between minimizing the number of new qualifications required and satisfying objectives 1-3 above. The algorithm begins with a set of existing product-site qualification pairs and proceeds by adding new pairs one at a time in a greedy manner.
