Modeling and Analysis of Semiconductor Supply Chains

Diese Seminarbeschreibung wurde vor dem Seminar auf unseren Webseiten veröffentlicht und bei der Einladung zum Seminar verwendet.


Supply chain management (SCM) problems have become more and more important in the last decade in the semiconductor industry. In the beginning, this was caused by the fact that initial operations (wafer fabrication, probe) are performed in highly industrialized nations, while later operations (assembly, packaging, and test) are carried out in countries where labor rates are cheaper. Today there are also centers of competencies (e.g. bumping) that may consist of only a few process steps that may be done in a different company owned facility or remotely by a subcontractor. These centers of competencies speed up innovations and reduce costs, but increase the complexity of SCM.

The semiconductor industry is capital intensive with the cost of an entire wafer fab up to nearly $ 10 billion US. The high cost is primarily due to extremely expensive machines, some up to $ 100 million US each. The manufacturing process is very complex due to reentrant flows in combination with very long cycle times and multiple sources of uncertainty. Capacity expansions are expensive and time-consuming. The semiconductor industry is an extreme field for SCM solutions from an algorithmic and also from a software and information systems point of view.

The major objective of the proposed seminar is related to developing a research agenda for semiconductor supply chain modeling and analysis topics. The research agenda should be developed around the following two main topics:

Topic 1:
Novel planning and scheduling approaches that can deal with the complexity and stochasticity of the semiconductor supply chain.

Topic 2:
Future information systems and supply chain management in the semiconductor industry.

This includes innovative modeling approaches for supply chain network planning, demand planning, master planning, and detailed production planning and scheduling in semiconductor supply chains and how the approaches will be embedded in future information systems.

One of the expected outcomes of the seminar consists of developing a significant draft of a conceptual reference model for planning and control of a supply chain in the semiconductor industry that can be used for analysis and performance assessment purposes and to foster a common understanding in the research community both in academia and industry. This includes specifying reference planning and control activities, the major information flows, and their interaction with a reference system of a physical supply chain.

The purpose of this seminar is to bring together researchers from different disciplines including information systems, computer science, industrial engineering, supply chain management, and operations research whose central interest is in modeling, analyzing, and designing complex and large-scale supply chains such as those in the semiconductor industry. Moreover, practitioners from the semiconductor industry who have frequently articulated their perception that academic research does not always address the real problems faced by the industry will bring in their domain knowledge to make sure that progress towards relevance, applicability, and feasibility will be made during this seminar.
