Production and changeover constraints

Question

Hello all,

I would like to know if there is any possibility in AIMMS to limit/penalize via constraints/costs the amount of changeovers done by a machine per type of product and even take into account the capacity lost linked to these.

Example:

Production Line A has the capability to produce products X, Y and Z
Changing the production to another product has a big impact on capacity linked changeover time (several days) and should be avoided as much as possible
In a month, there is a maximum of 1 changeover

How could I use AIMMS to model these constraints?

Can the changeover impact on capacity be modelled (amount of days lost)?
Can I set a penalty/cost in order to avoid changeovers as much as possible?
Can I set a max of changeovers for a specific period?

Many thanks in advance for your comments!

Hi CarlosSC Navigator is a tool for strategic and tactical network design, and not intended for detailed production planning. Therefore it doesn’t represent changeovers explicitly, but the impact of them is included in an overall efficiency figure that includes changeovers, unplanned downtime and machine run rates.You can use scenario analysis and capacity constraints to explore the economies of scale fromof more or fewer changeovers without representing them explicitly. This is usually the best way for strategic decision making.Or if you do need a detailed production scheduling tool these are supported by thewider AIMMS platformhttps://www.aimms.com/use-cases/production-planning-and-scheduling/
