OPTIMISATION AND DECISION MAKING - 2023/4

Module Overview

Nowadays, the design, planning and operations management relay on mathematical models the complexity of which depends on the detail of models and complexity of the problem they represent. In process industry these design and operation planning functions are particularly complex and a wide range of optimisation processes and methodologies are used to minimise risks and/or improve quality in making concomitant decisions. Consequently, the module intends to introduce to students the formulation of the decision making problems and application of optimisation techniques to support decisions with real-life worked examples.

Assessment pattern

Alternative Assessment

N/A

Assessment Strategy

The assessment strategy is designed to provide students with the opportunity to demonstrate

·         Understanding of scientific principles, methodologies and mathematical methods associated with decision making and optimisation, as well as the ability to formulate and solve particular optimisation problem in the final examination. The coursework tests and amplifies awareness and ability to formulate and solve a practical optimisation problem in engineering.

Thus, the summative assessment for this module consists of:

·         Coursework – 40%, 15 hrs (LOs  2, 3, 4)             

·         Examination – 60%, 2 hrs   (LOs 1, 2, 4, 5)

Formative assessment and feedback

• Formative verbal feedback is given during laboratory experiments


• Formative feedback on coursework is given verbally and available on SurreyLearn to provide feedback on understanding of optimisation and decision making process and respective problem formulation and solution.

Module aims

• A systematic understanding and critical awareness of the importance of the process of optimisation and decision making in process engineering;
• A knowledge of formulating decision-making problems and applying technology to support decisions;
• A knowledge and skill to use the General Algebraic Modelling System (GAMS) in solving engineering problems.

Learning outcomes

Methods of Teaching / Learning

The learning and teaching strategy is designed to:

• Introduce principles of decision making process in general and optimisation in particular and their implementation and use through theory and worked examples. This is mainly delivered through lectures and laboratory experiments using GAMS on independently worked out examples.

• 2 hours lecture per week x 11 weeks


• 1 hour tutorial x 11 weeks


• 2 hours revision lectures

Indicated Lecture Hours (which may also include seminars, tutorials, workshops and other contact time) are approximate and may include in-class tests where one or more of these are an assessment on the module. In-class tests are scheduled/organised separately to taught content and will be published on to student personal timetables, where they apply to taken modules, as soon as they are finalised by central administration. This will usually be after the initial publication of the teaching timetable for the relevant semester.

Other information

In line with Surrey’s Curriculum Framework, we are committed to developing graduates with strengths in Employability, Digital Capabilities, Global and Cultural Capabilities, Sustainability and Resourcefulness and Resilience. This module contributes to the five pillars in the following ways:

Employability

Most of tutorial sessions and the coursework are designed and positioned here such to provide students with and expose them to a more authentic (real world) problem solving experience towards at the end of their programme. Through this students will gain experience of report writing for specific audiences/stakeholders, and ability to demonstrate capability in problem solving directly applicable to a wide range of sectors, which could be cited in interviews and applications to show students’ experience of applying scholarly knowledge to another sector.

Digital capabilities

Significant level of digital skill is a clear output of this module which students gain through a direct and indirect exposure:

• Digital capability gained through a direct exposure includes the use of General Algebraic Modelling System (GAMS), a software tool for solving optimization and decision making problems. During every tutorial students use GAMS in computer laboratory gaining experience in running the software but also in using computers in more general terms;
• Digital capability gained through an indirect exposure includes teaching materials and key content available in multimedia forms through the Virtual Learning Environment Surreylearn.

Global and Cultural Capabilities

Engineering in general and Decision Making in particular are global synonyms and the tools and skills used on this module can be used internationally and multiculturally. Students learn about generic engineering and professional code of conduct and the importance of respect in teamwork. Students learn to work together in groups with other students from different backgrounds to solve a problem. This module allows students to develop skills that will allow them to develop applications with global reach and collaborate with their peers around the world.

Sustainability

Students will complete this module with social, ethical and contextually aware knowledge. This module has gender inequality (in the broadest and most inclusive use of the term) at its core, aligned with the UN’s gender equality sustainability goal. It also seeks to ensure community sustainability through the knowledge, skills and awareness students will have upon completion of the module.

Resourcefulness and resilience

This module directly contributes to the educational elements of resourcefulness and resilience as students are honing their autonomous learning to a sophisticated and advanced level. Throughout the module, from concept of formulating the problem to implementation of tools and finding solutions, students will be highly independent, yet supported by their supervisor in the course of tutorials. Students will gain particular skills in informed decision making as this is the core nature of the module They will have to problem solve, navigate ethical considerations and consider their arguments and findings in context. Within a network of support, students will further develop the extent to which they are independent and resourceful learners with a great deal of confidence in conducting and leading independent work towards solution.
