Development of an integrated system between Job Shop Scheduling and Employee Timetabling (ETT) with consideration of minimizing Labor cost as objective based on employee resource availability constraint.Development of an integrated system for Job Shop Scheduling and Computer Aided Process Planning with consideration of minimizing production cost.Optimization of Total Holding Cost subject to Tardy jobs and No Tardy jobs.An integration approach between JSS and Production Functional Areas encompasses the minimization of Overall production cost as objective based on production resource availability constraint. This book proposes a framework model for integration between the two production functions with an objective of minimizing labour costs based on employee availability constraint, minimizing manufacturing cost based on machine availability constraint, minimizing material cost based on material availability constraint, minimizing production cost and minimizing total holding cost.
