Batch Scheduling Using Matrix Approach under Demand Fluctuation

Batch process plays an important role in chemical engineering industry as
multiproduct operations can be done by reusing shared equipment. In order to
optimize its utilization, scheduling of batch processes are practised in the industry to
achieve the desired production quality using the shortest process time (makespan).
One of the state-of-the-art scheduling approaches is the application of simplitied
matrix modelling from sophisticated time algorithms. However, this method does not
address the realistic scenario of fluctuating product demand from clients. In this work,
matrix-based batch scheduling is fut1her expanded by including demand fluctuation
screening for a better planning and decision making by users. An algorithm is
introduced and implemented to achieve the multiple objective functions of short
makes pan, demand target, and high economic potential simultaneously.
