A Storage Assignment Model for Batch Preparation in Process Industries

J. Ashayeri, W. Selen

Research output: Working paperDiscussion paperOther research output


A new model formulation is developed for reducing the workload in pre-batching at a manufacturer of flavours and fragrances, by optimally assigning ingredients to different storage types, taking into account past usage of ingredients and several restrictions about volumes and number of storage units. Two models were developed, accommodating either fixed or variable shelf settings in its vertical carrousel warehouse, along with other varying storage types. The model was validated, yielding a sizeable reduction in workload, and run under varying scenarios of storage additions to reduce workload even further.
