1.1. Introduction

Brief presentation of the subject:

 

The course is designed as an extension of the basic concepts that were addressed in the course of Operational Research. In this course, the concept of modeling and optimization of systems as diverse as production or logistics is introduced.
In the course of Expansion of Operational Research we analyze nonlinear programming and it will be introduced the concepts of dynamic programming, stochastic modeling, queuing theory and simulation of complex systems.
The course has a clearly practical approach as a subject as Operations Research requires in the field of engineering, the resolution of practical cases and simulation of complex systems will be the key of the course.

1.2. Recommendations to take this course

It is valuable that the student possesses basic knowledge of algebra, calculus and has passed the courses of Statistics and Operational Research. It is also highly valuable to be familiar with the use of statistical software. 

1.3. Context and importance of this course in the degree

The course is mandatory for the Management Engineering profile. It is part of the first half of the 3rd year of the curriculum for the Degree in Management Engineering, which means that the student has acquired training in learning outcomes in the subjects of Mathematics I, Mathematics II, Statistics and Operational Research. Expansion of Operational Research course provides skills that will be useful tools in key areas such as production or logistics.


Almost all professional profiles of a management engineer involving decision-making processes, and require a certain skill in understanding basic mathematical models.

 

Therefore, basic training in the "science of decisions" is necessary. Operational Research has had an impressive impact on improving the efficiency of numerous and diverse organizations around the world. One could cite their contributions to production problems, the efficient use of materials and reliability of them, basic research and new product development. As in other sciences, Operational Research becomes a vital tool for engineers because it allows them to understand phenomena subject to variations and predict or control them effectively. In addition, simulation of complex systems can address real problems with prior information to avoid unnecessary costs and damage to the productive system.

1.4. Activities and key dates

The  course takes 15 weeks and take place in the computer room, theoretical concepts  will be reinforced with practical sessions solving exercises and practical cases using specific software. Two main tests throughout the course will be made. In addition, the continued work in the classroom will also be assessed by performing 2  participatory controls, involving the resolution of practical exercises.

2.1. Learning goals

The student, for passing this subject, should demonstrate the following results ...

 

  • Differentiate between stochastic and deterministic models.
  • Identify and develop more complex models that involved integer variables and/or nonlinear functions.
  • Identify and develop operational research models in real systems whose behavior depends on chance, in order to predict the performance of them and also to help in the decision making process, either at the stage of design or in the comparison of alternative policies.
  • Handle the basic mathematical principles necessary for the resolution of these models.
  • Use computer software to solve the proposed models.
  • Apply simulation models in the analysis of complex systems

2.2. Importance of learning goals

Operational research is a mathematical tool to address decision making in the company, it is based on the scientific method and uses quantitative analysis. Operational research applied to problems relating to the optimization of activities within an organization. It has been applied extensively in such diverse areas as transportation, production or public services,
to name a few.
The formulation of the problem, the construction of a mathematical model that summarizes the essence of the real problem, and the validity of this model are fundamental in optimizing resources. Justify the chosen model and solving technique used as an optimization problem, it is what validates the result itself and allows for improvement in the system.

3.1. Aims of the course

The subject and its expected results meet the following approaches and objectives:

the decisions in Industrial Organization Engineer are involved with many different areas within a production process. The concept of optimization is essential for such decisions. In this context, operational research is an essential tool because it provides quantitative methods that support any technical decision within the production process.
 
It is intended that the student is able to identify, analyze, formulate and solve actual decision problems related to the organization and management of production systems. It will be essential that students acquire the ability to determine the best strategy for action in order to improve the functioning of a system and be able to make decisions from a problem solving or a simulating complex system.
 
For this purpose, the course has an applied purpose, where is essential the resolution of practical cases.

3.2. Competences

Being passed the course, students will be more competent to ...

  • Ability to solve problems and make decisions with initiative, creativity and critical thinking.
  • Ability to communicate and transmit knowledge, skills and abilities in Spanish language.
  • Ability to work in a multidisciplinary group and in a multilingual environment.
  • Ability to learn continuously and develop independent learning strategies.
  • Basic knowledge of the use and programming of computers, operating systems, databases and software with applications in engineering.
  • Ability to solve mathematical problems that may arise in engineering. Ability to apply knowledge about: statistics and optimization.
  • Knowledge and skills to apply quantitative methods of decision in organizations.

4.1. Assessment tasks (description of tasks, marking system and assessment criteria)

The student must demonstrate that he/she has achieved the intended learning outcomes through the following evaluation activities:

 

  • Exams: During the course two written tests will be conducted. Will focus on theoretical and / or practical aspects of the subject. Its weight in the rating is 60%. Learning outcomes with those related are 1, 2, 3, 4 and 6.
  • Participatory controls: Throughout the course two controls participatory be made. Its weight in the rating is 10%. Learning results which are related are the 1, 2, 3, 4, and 6.
