Computerized Maintenance and Scheduling Management System is a system that had been developed to schedule for production line in an effective way. There are 3 subsystems which are production scheduling, maintenance and inventory. It is designed to manage equipment in the industry by generating a schedule using genetic algorithm and display it as an interactive Gantt chart.
Many industries face problems to create a good schedule. We need some good algorithm to create an optimized schedule. For this system, we use genetic algorithm (GA) to create a better solution by optimizing and simplify the schedule. Another problem is when machine breakdown occurs. The schedule needs to be regenerated. The rescheduling process will waste time. For this reason, we develop a dynamic Gantt chart so that end user can manually change the schedule if one or more machines breakdown. This can save time as it will not generate back the whole schedule.
There are some assumptions and constraints for the genetic algorithm part and dynamic Gantt chart part.
(i) Genetic Algorithm
§ There are no shortage on raw materials required for production
§ Schedule is generated according to deadlines, not weekly, monthly or yearly
(ii) Dynamic Gantt chart
§ A task cannot be moved to machines that cannot do the task
§ The order of tasks after drag and drop must follow the given task order
Along this research is a project development that is done simultaneously. The objective of this research is to find a suitable genetic algorithm method to do rescheduling with a minimal time and resulting a minimal processing time. The expected outcome is an algorithm that facilitates rescheduling and dynamic Gantt chart.
