Computers and Safety (CASA)

Overview

This course aims:

  • To introduce you to the issues to consider when computers are used in safety-critical or safety-related applications;
  • To give you an quick overview of how computer systems work, from basic hardware components up to application software;
  • To highlight areas of potential concern to safety engineers, including an in-depth examination of the software development process, considering especially aspects of requirements specification, design and analysis that are critical to deployment of computers in safety-critical applications;
  • To consider the structuring and collection of evidence for the software safety case.

By the end of the course, you will be able to:

  • Explain the issues presented by the use of software in safety-critical systems;
  • Evaluate software development lifecycle models for safety;
  • Describe the basic elements of a computer;
  • Discuss the relationship between system and software requirements;
  • Differentiate between “bottom-up” and “top-down” views of software assurance;
  • Discuss the issues in communicating requirements from one discipline to another;
  • Select and participate in the application of appropriate software safety analysis techniques;
  • Describe the role and principles of software architecture in the design process;
  • Identify the decisions relevant for safety in a software development process;
  • Compare the approaches taken by software standards;
  • Assess the appropriateness of software verification and analysis in a system safety argument;
  • Describe the issues and potential approaches to incorporating software COTS into a safety-critical system;
  • Discuss the state of the art and future directions in software safety.

Who is the course for?

This course is suitable for:

  • Practitioners across all domains including aerospace, military, railway, automotive, civil nuclear, civil maritime, medical devices and healthcare;
  • Developers of equipment safety cases during design for software, hardware, procedures, systems and/or platforms;
  • Developers of safety cases for operational safety and disposal;
  • Reviewers of safety cases within an organisation or as an independent activity;
  • Developers and reviewers of changes to existing safety-critical / safety-related equipment and operations;
  • Project managers where development of a safety case is a significant element of projects they manage;
  • Regulators of safety critical domains.

Prerequisites

A basic understanding of system safety terminology and lifecycle via prior learning or industrial experience. It is useful for you to have taken our Foundations of System Safety Engineering course, but we will accept equivalent industrial experience or prior learning.

If you are unsure about your previous experience, please email the CPD Admissions Team at cs-pgt-admissions@york.ac.uk so that we can assess your suitability for this course.

How is the course taught?

During your course, you will have full access to the benefits of the York approach, with experienced and knowledgeable lecturing staff on hand throughout the week, as well as the opportunity to gain insights from your industry peers.
 
During the 2021/22 academic year courses will be taught in a blended format. There will be three days of face-to-face teaching in York, taking place on Tuesday to Thursday of the teaching week. In addition students will be provided with self-study materials totaling some 10 - 15 hours of study time. These will be split between work to be completed before the in-York sessions and materials to be studied afterwards. The mode of teaching delivery is subject to change according to government guidance relating to Covid-19.

During the teaching week there will be a combination of lecture materials and case studies to explore. The case studies give you the chance to work through an example to reinforce your learning from the lectures.
 
Each course ends with an optional assessed exercise that is undertaken away from the University over 6-7 weeks following the taught element of the module. Each assessment takes approximately 65 hours in addition to the scheduled teaching time, of which we estimate students spend 30 hours undertaking private study plus 35 hours writing up the assessment. All assessed exercises are open (so you won't take an exam in supervised conditions), and comprise a report, case study, or documented piece of software.
 
If you choose to take the assessment and you pass, your results can count towards the completion of one of our postgraduate awards: 

You should apply for your Masters, Diploma or Certificate award after taking no more than 40 credits of modules. All components of your chosen postgraduate award, including modules taken as CPD short courses, must be taken within a five year time period.

When will this course be taught?

Our short courses are each taught in one-week blocks, enabling you to undertake your studies alongside your work commitments.

In the 2021/22 academic year the teaching week for Computers and Safety (CASA) will take place in the week commencing 07/02/2022. ​Preparatory materials are released the week commencing 31/01/2022. Registration closes on 21/01/2022.
