IBM said Ilog’s board has approved the deal, and holders of about 10% of Ilog’s shares have already accepted the offer. After the acquisition, IBM plans to combine its business process management, service oriented architecture, and business optimization technologies with Ilog’s BRM systems software.

Ilog has 500 OEM, solution integrator, and independent software vendor partners.

IBM said the acquisition will enable it to provide rules management tools for information and application lifecycle management across platforms including its WebSphere application development and management platform. The integration will also provide visualization for Lotus products, optimization within Tivoli applications, and supply chain management assets for planning and scheduling.

Tom Rosamilia, general manager at IBM WebSphere said: Ilog’s software allows businesses to more effectively manage and automate the decision making process, giving companies an opportunity to react with incredible speed and accuracy. IBM has partnered with Ilog for over a decade, and by adding Ilog’s capabilities to IBM’s software portfolio, this is a great combination to provide value to our clients.
