Scheduling Theory

Course in Winter 2017/18

Scheduling involves the timely allocation of tasks to scarce resources with the objective to minimize some cost function. Such problems appear in various applications, e.g., in production planning, logistics, project management, or when operating computing systems. This lecture will cover: a classification of scheduling models, complexity of scheduling problems, the design and analysis of exact and approximation algorithms, single and parallel machine models, flow shop and open shop problems. The focus lies on the design and mathematical analysis of algorithms using combinatorial techniques, dynamic programming and linear programming.
