Unified Data Model
All of Adexa applications from network planning to supply chain planning, plant planning and sequencing as well as other modules are based on a unified data model. This is a unique feature of Adexa applications. But why is a unified data model important? There are a number of reasons. Firstly, it drastically reduces the effort and cost related to integration of modules both internally to the applications as well as to the outside modules such as ERP and MES systems. For example, the number of tables needed to integrate with any or all of Adexa applications is as few as 16 tables. Secondly, if different data models are used at (say) supply chain level and plant level, then the plans sent to the users at the factory level from the supply chain do not make sense! They are either too much or too little for the available capacity and material. This can cause, unreliable promised dates and definitely lower the customer service level and/or unnecessarily cause increase in inventory. In addition to the above advantages, because of having the same data model at different levels, once plant level model of Adexa is available, one can immediately and automatically form a supply chain model and go even further and define a network model without any additional tables or integration. As it can be imagined, this is a huge savings in cost and effort to perform high level analysis and high level planning.
In Sales and Operation planning, the demand planning, inventory planning and supply planning all need to speak the same language. Constraints and requirements at the demand level need to be accurately translated to supply constraints and inventory requirements as defined by the attributes of the demand and supply (see Attribute-Based Planning white paper). Having a unified data model implies no translation is needed and enables smooth transition of demands into supply constraints and availability. The bottom line is that a unified data model saves cost, time, effort and leads to a much lower cost of ownership and more reliable plans.
