Business Informatics / Operations Research

Module name (EN):
Name of module in study programme. It should be precise and clear.
Business Informatics / Operations Research
Degree programme:
Study Programme with validity of corresponding study regulations containing this module.
Industrial Engineering, Bachelor, ASPO 01.10.2013
Module code: WIBASc455
The exam administration creates a SAP-Submodule-No for every exam type in every module. The SAP-Submodule-No is equal for the same module in different study programs.
Hours per semester week / Teaching method:
The count of hours per week is a combination of lecture (V for German Vorlesung), exercise (U for Übung), practice (P) oder project (PA). For example a course of the form 2V+2U has 2 hours of lecture and 2 hours of exercise per week.
2V+1U+1P (4 hours per week)
ECTS credits:
European Credit Transfer System. Points for successful completion of a course. Each ECTS point represents a workload of 30 hours.
Semester: 4
Mandatory course: yes
Language of instruction:
Written exam

[updated 13.09.2018]
Applicability / Curricular relevance:
All study programs (with year of the version of study regulations) containing the course.

WIBASc455 (P450-0099) Industrial Engineering, Bachelor, ASPO 01.10.2013 , semester 4, mandatory course
Workload of student for successfully completing the course. Each ECTS credit represents 30 working hours. These are the combined effort of face-to-face time, post-processing the subject of the lecture, exercises and preparation for the exam.

The total workload is distributed on the semester (01.04.-30.09. during the summer term, 01.10.-31.03. during the winter term).
60 class hours (= 45 clock hours) over a 15-week period.
The total student study time is 150 hours (equivalent to 5 ECTS credits).
There are therefore 105 hours available for class preparation and follow-up work and exam preparation.
Recommended prerequisites (modules):

Learning outcomes:
Business Informatics:
After successfully completing this module students will:
_        be able to outline the basic subject areas of business informatics
_        be able to describe how business informatics is connected to related disciplines
_        be able to explain and classify the embedding of IT systems in an organization, its technology and with regard to a company´s strategic goals
_        be able to visualize processes by means of common notations and classify these notations with regard to their intended use
_        be able to explain the basic application types of database systems, ERP, decision support systems, workflow and information management systems and differentiate between their application
Operations Research:
After successfully completing this module students will be able to:
_        describe numerous application areas of Operations Research, in particular linear optimization
_        demonstrate the role of OR methods for decision-making in practice
_        independently create mathematical models for LPs
_        identify and apply suitable solution methods
_        use the Microsoft Excel optimization tool Solver to create and solve smaller optimization models and interpret the solution.
_        Create a project plan using the precedence diagram model
Problems from the field of industrial engineering will be used as application examples so that students can apply the knowledge they acquire in the lecture to practical situations.
