2.5 Aggregate and Master Planning

We need to briefly consider two other types of operational planning in a production environment, aggregate and master planning. These build off our study of capacity planning and the management of performance.

To enable the strategic plan or business plan to be devised, organisations often rely on aggregate planning or master planning to enable broad decisions about capacity to meet total demand. Firstly, organisations need to determine current capacity and likely aggregate demand for broad resource transformation processes. To assist in devising a meaningful plan linked with overall capacity, organisations often undertake planning based on a fictitious product with an average cost, or a unit of production (e.g. cartons, customer, per day production, number of calls processed, etc.) or a family of products that have the same resource and transformation requirements to produce an output. Pulling together operational or tactical plans from across multiple teams or specific areas can result in an Aggregate Plan or Master Plan.

Aggregate Planning involves grouping like products or services for a given client into related or natural families (determined by skills, resources and equipment are the same to complete production). Aggregate capacity is then planned based on resources and process requirements to produce the family of products (capacity group) to meet planned aggregate customer demand.

Master planning can be either -

Steps in Aggregate Planning include:

  1. Choose capacity group or fictitious product/service
  2. Determine aggregate capacity to transform resources
  3. Converting average aggregates into actual items of production
