1. Introduction

The aim of the assignment is to use specific operations software to simulate and optimise the manufacturing process of an air motor manufactured within the EIC workshop environment whilst appreciating the role of operations management. A written technical report will show the creation of the simulation and operational decisions taken by you prior to starting the simulation. The report will contain a proliferation of illustrations/screenshots of elements of your simulation. Further research is expected to focus on the wider application and significance of operations management techniques.

2. Technical Tasks

Simulate the parts manufacturing and the assembly processes using SIMUL8 software for the mass production of the Air Motor as detailed in this brief. Produce a report covering the following five elements:

• Simulation Assumptions

You are to make operational assumptions for your simulation to simplify its construction.  Your initial priority should be to create a simple simulation that gives credible results; to gain higher grades look to add elements to the simulation to expand, further refine the model and interpret the results to optimise the processes.  This will involve making your own assumptions for certain factors, you may work in groups to discuss and decide on the initial assumptions. Explain and justify your assumptions and decisions and consider how the simulation could be refined once a basic simulation is working.

Sample assumptions to build your initial model: (it is not compulsory to use these, you are free to create your own assumptions)

• All staff have the same skill level and can be assigned to any of the activities.
• All raw materials arrive on time, cut to length and are always in stock.
• Each machine can operate 8 hours a day 5 days a week.
• Bought-in items such as springs and nuts & bolts arrive on time and are always in stock.
• All queues are infinite.
  • Target Goals and KPI’s

Before you begin your simulation, plan, discuss and decide what measurable factors and key performance indicators (KPIs) you wish to derive from the simulation from an operations management point of view e.g. utilisation of machines, queues, maximum capacity etc. Explain and justify your decisions.

• Simulations

Determine the maximum weekly capacity of EIC workshop to manufacture and assemble the Air Motors (see CAD drawing of workshop layout).

Initially build a simple simulation to show the flow of work through the different manufacturing activities, do not attempt the whole simulation in one go.

To gain higher marks look to add elements to the simulation to expand, refine and optimise it. This could include (but is not limited to) things such as adding labour resources to activities to determine minimum staffing levels to achieve maximum capacity or adding Inspection/Quality Control into the process. Highlight potential bottlenecks in the process and seek to improve capacity and efficiency in the process.

• Simulation Results

Present the findings from your simulations in a report with respect to your original target goals and KPI’s. Liberally illustrate your report with screenshots of ways in which your simulation functions. Comment on your results and justify your decisions for improvements.

• Role of Operations Management and Manufacturing

Describe the scope, context and significance of Operations Management in this manufacturing task. Through further reading and research explain what operations management techniques should be adopted for this type of work beyond simply manufacturing the Air Motor e.g. Project Management, Quality, Statistical Process Control, Lean Manufacturing, Six Sigma. You do not have to incorporate any of these elements into your simulation.

3. Things to Consider

Here are a couple of points to consider when writing the final report:

• For Information regarding the machines and resources in the EIC workshop please visit the following link: https://www.uclan.ac.uk/about_us/facilities/eng_cnc_workshops.php
• The basic model should represent the full current component manufacturing and assembly processes. The assembly processes will be introduced in the practical sessions.
• Appendices are used only to provide further explanation of a specific idea and it should not be used to provide vital information in the report, i.e. the reader does NOT need to read the appendices yet still understands the entire report.
• Figures should have captions and numbers. Sections should be numbered as well.
• Focus on your input and the use of the software. For instance, do not explain how the software’s buttons work, you should rather explain the selection of the input data. For example:

Do not write: “an activity button that is shown in Fig. 1 gives the ability to input the time, standard deviation, and the resources required for doing the activity”.

You may write: “the sheet metal forming process is represented by an activity button that requires both time and resources. Fixed time of 1 min and two operators are used as an input for this activity”.

• Any references should be cited using the Harvard reference system.
