Debottleneck plant

Formats and tools

Unit Description
Reconstruct the unit from the xml and display it as an HTML page.
Assessment Tool
an assessor resource that builds a framework for writing an assessment tool
Assessment Template
generate a spreadsheet for marking this unit in a classroom environment. Put student names in the top row and check them off as they demonstrate competenece for each of the unit's elements and performance criteria.
Assessment Matrix
a slightly different format than the assessment template. A spreadsheet with unit names, elements and performance criteria in separate columns. Put assessment names in column headings to track which performance criteria each one covers. Good for ensuring that you've covered every one of the performance criteria with your assessment instrument (all assessement tools together).
Wiki Markup
mark up the unit in a wiki markup codes, ready to copy and paste into a wiki page. The output will work in most wikis but is designed to work particularly well as a Wikiversity learning project.
Evidence Guide
create an evidence guide for workplace assessment and RPL applicants
Competency Mapping Template
Unit of Competency Mapping – Information for Teachers/Assessors – Information for Learners. A template for developing assessments for a unit, which will help you to create valid, fair and reliable assessments for the unit, ready to give to trainers and students
Observation Checklist
create an observation checklist for workplace assessment and RPL applicants. This is similar to the evidence guide above, but a little shorter and friendlier on your printer. You will also need to create a seperate Assessor Marking Guide for guidelines on gathering evidence and a list of key points for each activity observed using the unit's range statement, required skills and evidence required (see the unit's html page for details)

Self Assessment Survey
A form for students to assess thier current skill levels against each of the unit's performance criteria. Cut and paste into a web document or print and distribute in hard copy.
Moodle Outcomes
Create a csv file of the unit's performance criteria to import into a moodle course as outcomes, ready to associate with each of your assignments. Here's a quick 'how to' for importing these into moodle 2.x

Reference books for 'Debottleneck plant' on This online store has a huge range of books, pretty reasonable prices, free delivery in Australia *and* they give a small commission to for every purchase, so go nuts :)

Elements and Performance Criteria



1. Identify rate limiting step/process.

1.1. Determine throughput of plant/area

1.2. Determine capacity of units within plant/area based on design and/or performance data

1.3. Identify which unit(s) is operating at capacity/is the bottleneck

2. Investigate bottleneck.

2.1. Analyse the science of what is occurring in the bottle neck unit

2.2. Analyse the engineering/design specification of the bottle neck unit

2.3. Determine the root cause of the capacity limitation of the bottleneck unit

2.4. Investigate methods of increasing the capacity of the bottle neck unit

2.5. List solutions to the bottle neck.

3. Select technically best solution.

3.1. Investigate impact of solutions on the other units of the plant/area

3.2. Identify any 'knock on' effects of solution

3.3. Determine process/quality benefits and costs of solutions

3.4. Determine economic benefits and costs of solutions

3.5. Short list and rank the best solutions.

4. Compare hazard profile of possible solutions.

4.1. Organise a hazard analysis (eg HAZOP) for the solutions according to company procedures

4.2. Ensure that all stakeholders are represented on the hazard analysis team

4.3. Brief the hazard analysis team on the problem and solution alternatives under evaluation

4.4. Eliminate alternatives which do not meet hazard requirements

4.5. Rank remaining competing items by safety performance.

5. Make final choice of solution.

5.1. Seek further information where necessary to allow a rational selection to be made

5.2. Choose the solution which meets all required minimum standards and will provide the best solution

5.3. Verify choice in discussion with production and engineering managers and other key stakeholders

5.4. Obtain necessary approvals/authorisations

6. Check solution.

6.1. Initiate and monitor the implementation of the solution.

6.2. Ensure all checks and acceptances are done to procedures

6.3. Conduct trials/test runs as required

6.4. Collect and analyse data.

7. Complete modification.

7.1. Evaluate performance of solution

7.2. Make adjustments as required

7.3. Ensure plant procedures and training material updated

7.4. Ensure plant drawings and engineering specifications are updated

7.5. Complete all other required paperwork.
