IEN 960B, Planning and Scheduling in Manufacturing and Services

This course will introduce the area of scheduling from the theoretical and practical point of view. Both classical and new methods for solving planning and scheduling problems are presented. Description of general purpose scheduling procedures gives the basic overview of solving methods. Various models for planning and scheduling in manufacturing and services are described and algorithms for their solution are presented. The models include real-life problems like project planning, scheduling assembly systems, timetabling, workforce scheduling, or telecommunication planning. Each student will learn how to use state of the art optimization software CPLEX and GAMS.

IME 960 B, Logistics and Supply chain

The overall objective of this course is to introduce and explore issues relevant to logistics and supply chain management. This course enables students to understand the characteristic elements of integrated business logistics, the role and application of logistics principles to supply/demand/value chain management, the application of a selection of inventory management / analytical tools in solving logistical problems, aspects of strategic integrated logistics management and benchmarking and global integrated logistics activities.
