Quantitative Methods in Management

Part : Operations Research

Operations research (OR) is a discipline that aims to solve complex real world decision problems using scientific approaches. Application areas of this discipline are various: transportation, production systems, telecommunication, administration, etc. The course gives an introduction to the most popular mathematical models and methods of operations research: linear programming, network models (minimal spanning tree problems and shortest path problems), project scheduling with PERT/CPM, decision making under risk and under uncertainty.

Part : Statistics

In this course, the methods studied in basic statistical courses are adapted to analyzing useful applied issues in Economics and Management (comprehension of a situation and its evolution, support for decision-making...).
Covered contents will be regression and/or classification analysis. Multivariate aspects will be developed as well as time dependencies (time series).

In relation with the Assurance of Learning process of HEC Liège, the learning objectives adressed in this course are:

• Strategy: This course will help students to demonstrate scientific precision and a critical mind.
• Implementation: This course will encourage students to adopt a holistic perspective when analyzing a complex management situation, and to take into account the different functions of the organization as well as the legal constraints and opportunities.
• Implementation: This course will exercise students in the ability to take advantage of data digitalization. (MBA excepted)
• Quality and Performance Control: This course will exercise students' ability to adopt a holistic perspective when analysing a complex management situation.
• Communication : This course will allow students to improve their proficiency in one foreign languages (among the 3 languages required by the program).
• Adaptability: This course will encourage students to be curious and to show a scientific precision of academic level.

• To acquire a basic knowledge about the mathematical models of real world decision problems and the fundamental methods of OR.
• To be able to solve and interpret correctly the solutions of simple OR problems.
• To be able to recognize the situations where OR techniques can be used as decision making tools and to interpret correctly the conclusions which can be derived using these techniques.

Part : Statistics

C1. To acquire an overview of statistical problems met in the fields of Economics and Management.
P2. To be able to solve and interpret solutions of practical simple problems related to the theoretical part of the course.
P3. To be able to recognize situations where studied methods can be applied and what are their limitations in such particular situations.
More generally, on the program (master in management) point of view, the course addresses the following Key Intended Learning Outcomes:

• To understand, in management situations, the transversal tools of quantitative reasoning, information systems and project management.
• Developing a critical sense (arguing).
• Developing a transversal global vision.

Part : Operations Research

Face-to-face: The topics are covered in 5 * 3 lecture hours and are treated using numerical examples that are similar to the exercises of the written exam. At the end of each chapter, if time permits, one to two numerical exercises are studied within the lecture hours. At the end of the semester, an interactive exercise session, before which students choose the exercises to be studied, is organized.
Distance-learning: Numerical exercises, their solutions, and multiple choice tests are provided on the virtual campus Lol@.

Part : Statistics

Used methodology
A1. Ex-cathedra classes: theoretical introduction and applications (quick overview of introductive videos and elementary notions, presentation of various methods, interpretation of their solutions, examples)
A1. Study and comprehension of the course material
A2. Supervised software applications: the professor presents the software to the students and gives them exercises. Each student is expected to solve those exercises with the possible help from the professor.



Overview of the course agenda
The course starts on 4 November October and ends on 9 December. The statistical part of the course consists of 5 three hours lessons.
Decomposition of the student workload
A1 Ex-cathedra course (10h)
A2 Study (30h)
A2 Software applications (5h)
A2 Software training (12h)
Exam (2h)

Documents that can be found on the virtual campus Lol@:
1. Syllabus: The course notes and the PowerPoint presentations used during the lectures can be found on the virtual campus Lol@. Students are wanted to be in possession of these notes during the lectures.
2. Exercises: Students will be provided with some numerical exercises, their solutions, and multiple choice tests that they can use to practice their knowledge and to prepare themselves for the written exam as the chapters are treated during the semester.

Part : Operations Research

The second session exam of the part "Operations Research" will take place on Thursday, August 27, from 13:00 to 15:30.
Lol@Exams (https://examens.hec.uliege.be) platform will be used to realize this online written exam.
Students can participate to the exam only if they are officially registered to the second session exam of the course "Quantitative Methods in Management" on MyULiège.
The online written exam will be composed of 4 questions questions with open answers.
For each question, there will be a separate assignment. When students will clique on the assignment of a question, they will have access to the question description in PDF format. For each question, they will need to use the corresponding assignment to upload their handwritten answer. For each question (assignment), they can upload only a single PDF file. Other file formats are not accepted.  
All the questions will be accessible simultaneously at 13:00. Students will have a total of 2 hours and 30 minutes to prepare and upload their PDF files. That is, they will not be able to upload documents after 15:30. During the exam, students can work on the questions in any order. They will also have the possibility to delete an already uploaded file and upload a new version until 15:30.
Additional information regarding the second session exam is and will be avalilable on the Lol@ course page.
