By Doug Bartholomew The current applications software market is ailing but not hopeless. At least not for Rockville, Md.-based Manugistics Group Inc., which last week landed a major customer win in Airgas Inc. The largest U.S. distributor of industrial, medical and specialty gases, Airgas will use Manugistics NetWorks Demand and NetWorks Fulfillment software to improve inventory management and order fulfillment. "Manugistics supply and inventory management solutions...will help us ensure that we continue to exceed the expectations of our more than 1 million customers, by providing the right product to the right location at the time promised," says Michael Molinini, senior vice president of hardgoods at Airgas. The software packages will enable Airgas to create more accurate forecasts down to the stock keeping unit (SKU) level, taking into account seasonality, new product introductions and promotions, geography, and other data.
