"The planning and scheduling functions at Danone were historically addressed by using several systems, both home-grown and packaged applications. But even in combination, they couldn’t meet all of our requirements and manage the true complexity of the fresh dairy business. The goal of Themis [ERP worldwide program] was to find a corporate solution that could satisfy our business goals and the ease-of-use requirements of our planners" - Jean-Michel Egu, Director Business Solution, Danone
Danone is one of the most successful healthy food companies in the world, with around 80,000 employees.Today, in volume, Danone is the world number 1 in fresh dairy products, number 2 in bottled waters, number 2 in baby nutrition and the European leader in medical nutrition.
Danone’s main goal was to implement a flexible solution capable of improving key operational performance metrics such as inventory coverage, operational efficiency, equipment utilization, product waste, and changeover and cleaning costs. Important secondary goals included giving planners a better tool for performing what-if analysis and rescheduling, and implementing a solution that complemented the major investment Danone was making in SAP APO for supply chain management.
IBM® ILOG Plant PowerOps extends SAP APO for the requirements of fresh dairy production planning and detailed scheduling. . IBM Software Services for WebSphere and Danone Themis collaborate to meet Danone business requirements.
The IBM solution increased Danone’s service levels and operational efficiency, while reducing inventory and production costs. The plant replaced a home-grown system, which took two days to generate an imperfectly optimized plan, with a system that generated a far better schedule in under 15 minutes.
Approximately 57 percent of Danone’s revenue comes from its fresh dairy product division, which has more than 40 plants worldwide. The division grew 4.6 percent in sales volume in 2009, and has been experiencing year-on-year growth rates exceeding 10 percent in many emerging markets, including Russia, Turkey, Argentina and Mexico.
The fresh dairy division has multiple product lines, including solid yogurt, liquid yogurt, desserts and fresh cheese. The individual products are made through a complex, multistep process. This case study focuses on the yogurt-making process. In order to make yogurt, milk has to be pasteurized and fermented to create batches of “white mass,” which are then placed in containers of various sizes, sometimes with fruit or other ingredients. A fresh dairy plant may make more than 10 types of white mass that differ, for example, in percentage of cream and type of yeast. A typical plant produces more than 100 finished products on 10 to 20 packaging lines. Between pasteurization, fermentation and storage, as many as 100 tanks can be used. And because the plant produces food, extra care must be taken to ensure high standards of sanitation, control of allergens, batch traceability and maximum product freshness.
The plant must closely coordinate the two primary production steps: the transformation of raw materials such as milk, milk powders and yeast, into white mass, and the filling and packaging of the final product. The right amount of white mass has to be scheduled, and it has to be used as quickly as possible. Operational scheduling challenges include:
Deciding which and how much white mass to produce in each tank given the available connections to the filling and packaging lines
Finding the best time to clean the tanks and the filling lines given health and nutrition labeling requirements, and the availability of cleaning equipment
Synchronizing material consumption with white mass availability and freshness
Respecting batching policies for compliance with traceability regulations
Maintaining a steady supply of finished goods within a minimum and maximum inventory corridor
To these production challenges must be added those for high demand variability. Fresh dairy products are consumer goods with significant promotional marketing and a steady introduction of new products. Demand is often uncertain. New products may steal sales from old products or simply contribute to market share, and marketing campaigns can result in sales that are higher or lower than forecasted. And in the fresh dairy industry, the challenges associated with demand variability are compounded by the short shelf life of the finished products and relatively long production lead times—three to four days from milk pasteurization to final product. Poor production plans lead to both product waste and stock shortages, making agility and regular rescheduling critical.
Danone knew that IBM ILOG was the leader in optimization technology, and that IBM ILOG optimization engines executed the models in SAP APO. When the company heard that IBM ILOG had developed an integrated production planning and detailed scheduling application for the special challenges faced by process manufacturers, it wanted to learn more. And when the company realized the application was a purely analytic application designed to perfectly complement their SAP software, it wanted to try it out.
To make sure IBM ILOG Plant PowerOps (PPO) could safely meet the expectations of Danone’s business units, Danone and IBM ILOG created a team composed of production planners and business and IT managers from Danone, and optimization and detailed scheduling consultants from IBM Software Services for WebSphere. This task force analyzed the needs of four different Danone fresh dairy plants before formally evaluating IBM ILOG’s application as a solution. Since IBM ILOG PPO meets the very operational complexities that Danone deemed most important, discussion focused primarily on ease of use for the planners, required metrics, and integration with SAP. Once the team felt all the requirements were well understood and addressed, Danone decided to proceed with a pilot project in 2006 in Mexico, at Irapuato, one of the largest fresh dairy production facilities serving a market growing at 25 percent per year at the time. The plant’s capacity was constrained, so any improvement in scheduling efficiency would result in significant benefits.
Danone moved from planning once a week with mixed scheduling quality to high-quality planning and rescheduling whenever necessary. The planners appreciate the ease of use, plan feasibility, schedule quality, greater amount of information on production orders, activities and resources at their finger tips, and availability of new operational and financial metrics. IBM ILOG PPO’s integrated planning and scheduling approach delivers value beyond plan feasibility and schedule optimization. It also serves as a tool for negotiations between the manufacturing and supply chain departments, allowing them to collaborate more easily to find the best balance between inventory levels and operational efficiency. Now, everyone involved can see the impact of unexpected changes in demand on the manufacturing process, as well as those of production scheduling decisions on inventory levels and order fulfillment rates.
With the Irapuato plant’s constrained capacity and Danone’s rapid market growth in Mexico, the efficiency resulting from the IBM ILOG PPO solution has contributed greatly to the company’s profitability. And while asset utilization gains have certainly translated into lower operating costs and higher margins, the biggest financial benefits have come from increased sales and market share.
“We have compared production plans generated with and without IBM ILOG Plant PowerOps. We have been extremely happy to see that IBM ILOG’s application generates plans that improve every single one of our key performance indicators. Our plant in Irapuato is now equipped with an excellent planning and scheduling tool providing the best possible plans, while improving our operational flexibility and our ability to react quickly to unexpected events. This pilot project was delivered on time and on budget. Within Danone, the news spread quickly. We have since implemented the solution in Russia, Argentina and the US and five plants in France are planned to go live by the end of 2010.”

IBM Software Services for WebSphere and SAP integration
Consultants from IBM Software Services for WebSphere played an important role in the Danone project. With many years of experience in optimization and detailed scheduling, they worked side by side with the Danone team to ensure the success of the project.
“The product knowledge, experience and dedication of the IBM Software Services for WebSphere consultants have been remarkable during all phases of the project, from project planning to SAP integration to user acceptance testing and go-live. Team experience allowed us to quickly solve difficult situations that always arise during critical phases of such projects. It is in these situations that you can fully appreciate the value of working with a first-class team.”
-- Krzysztof Kaziow, Danone Project Manager,
The consultants’ experience with SAP was as critical as their expertise in optimization. SAP is the single repository of both master data and transaction data. Changes in master data, such as resources to schedule or products to make, are done only in SAP. This data, along with expected inbound shipments of raw materials, current inventories and production orders, all need to be easily available to the IBM ILOG planning and scheduling application without any special effort. This is accomplished by having IBM ILOG PPO launched directly from inside the SAP PP/DS environment, eliminating the need for planners to log out of one environment and into another. For the planners, who manage production orders in PP/DS and planning and scheduling in IBM ILOG PPO, this ease of use is critical to the practical use of this analytic extension to SAP APO PP/DS.
