There are three important functions of manufacturing which process planning, scheduling and due date assignment. Instead executing these separately, combining them together helps making more realistic applicable plans. In this problem context random search, semi-tabu, random/semi-tabu hybrid, evolutionary strategies, random/evolutionary strategies hybrid methods utilized in solution. Different ...

Production scheduling and preventive maintenance planning decisions are inter-dependent but most often made independently. Given that maintenance affects available production time and elapsed production time affects the probability of machine failure, this interdependency seems to be overlooked in the literature. We propose an integrated model that simultaneously determines production schedulin...

Production scheduling (planning) of an open-pit mine is the procedure during which the rock blocks are assigned to different production periods in a way that the highest net present value of the project achieved subject to operational constraints. The paper introduces a new and computationally less expensive meta-heuristic technique known as imperialist competitive algorithm (ICA) for long-term...

Addressing an integrated decision-making structure for planting and harvesting scheduling may lead to more realistic, accurate, and efficient decision in fresh product supply chain. This study aims to develop an integrated bi-objective tactical and operational planning model for producing and distributing fresh crops. The first objective of the model is to maximize total revenue of supply chain...

The objective of this research is to develop and evaluate e€ective, computationally ecient procedures for scheduling jobs in a large-scale manufacturing system involving, for example, over 1000 jobs and over 100 machines. The main performance measure is maximum lateness; and a useful lower bound on maximum lateness is derived from a relaxed scheduling problem in which preemption of jobs is bas...

Assembly plays an important role in any production system as it constitutes a significant portion of the lead time and cost of a product. Virtual computer-integrated manufacturing (VCIM) system is a modern production system being conceptually developed to extend the application of traditional computer-integrated manufacturing (CIM) system to global level. Assembly scheduling in VCIM systems is ...

Shipbuilding is acknowledged as an uncertain, complex, and unique industrial effort that yields massive products consisting of numerous parts vulnerable to unexpected events. The industry also dominated by customer requirements through designs tailor-made for a specific ship. Planning in shipbuilding therefore considered formidable process. Consequently, many studies have been conducted develop...

In most current APS (Advanced Planning and Scheduling) systems the planning and scheduling tasks are handled separately using different methods and technology from the areas like Artificial Intelligence and Operations Research. Recently, Constraint Programming becomes a roof over several solving technologies that allow us to solve both planning and scheduling tasks within single declarative fra...
