Aggregate planning acts as a blueprint for all operational planning activities. Despite
the substantial amount of research that has been done in determining methods to
improve aggregate planning approaches, the industry is still at a loss when it comes
to working on the tactical planning aspect, especially in aggregate production.
Therefore, this research work aims to present a comprehensive and generalised
framework that will formulate a realistic batch production environment using an
interactive Production Decision Support System. This system consists of an aggregate
planning framework that combines a simulation model and a Pinch Analysis graphical
approach to improve the effectiveness and efficiency of the decision-making process.
The target is to allow operational opportunities to be captured at first sight and thus,
maximise organisational profit. The simplicity and practicality of this new Production
Decision Support System is demonstrated through two illustrative examples where a
total of four heuristics were identified and turned into the new strategies to avoid the
stock-out scenarios.
