Semiconductor manufacturing is one of the most complex and capital-intensive processes composed of several hundreds of operations. In today's competitive business environments, it is more important than ever before to manage manufacturing process effectively to achieve better performances in terms of customer satisfaction and productivity than those of competitors. To obtain such fruitful outco...

Lean manufacturing is a systematic approach to identifying and eliminating wastes (non-value added activities) through continuous improvement by conveying the product at the pull of the customer in pursuit of production. In a more basic term, more value with less work. Since lean manufacturing eliminates many of the problems associated with poor production scheduling and line balancing, lean ma...

Planning and scheduling are areas attracting an unceasing attention of computer science community. However, despite of their similar character, planning and scheduling problems are usually handled independently using different methods and technologies. While Artificial Intelligence technology is more relevant for planning problems, Operations Research has a long tradition in studying scheduling...

We address the simultaneous planning and scheduling of parallel multi-product batch reactors, a challenging problem that has been motivated by a real world application at the Dow Chemical Company. We propose a novel continuous time MILP model for the simultaneous planning and scheduling that is based on slot representation. While effective for short-term scheduling, the proposed model becomes c...

In traditional approach, planning and scheduling are two separate and successive operations. The process planning phase is mostly about the physical aspect of planning, where a product range, production quantities, machines, tools, material and accessories are selected. The emphasis in the second, scheduling phase, is on the time aspect. The plan is the basis to determine the sequence of operat...
