The Scenario Description
Mero Showers Ltd is a major Manufacturer and Distributor of Power Showers, Electric Showers, and Mixer Showers. This company has been operating since 1972 and has consolidated its position as one of the major manufacturers of showers for the UK market. Recently, an aggressive marketing campaign from competitors has made the company lose market share. To avoid losing more market share, the Mero showers Ltd has made a significant investment in technology, research and development and new product development. In turn, new variations of the types of showers on offer have been launched to market.
• The company expect to see returns for their investment and have forecasted the increase in expected orders starting with the prediction of the arrival of different types of shower parts used in the assembly of Power, Electric and Mixer showers (see table 1 below).
• The probabilistic distribution of inter arrival times for the arriving parts is shown in table 2. Assuming a typical 5 day working week (9:00am-5:00pm) with 1 hour lunch break for all members of staff.
• After arriving, all parts are unloaded in an unloading bay on a first come first serve basis. One yard operative is tasked with unloading the parts, organising them, quality checking for any defects. The yard operative has been at Mero Showers Ltd for over 5 years and is experienced in the job. The operative can complete the process of unloading, checking and organising ready for assembly in on average 30 minutes. The operative has lunch break from 12:00-1:00pm.
• Once the arriving parts have been organised and checked, assembly process will be applied in an assembly cell. This assembly cell consists of 4 assembly bays that used to assemble the arrived parts. 4 workers also known as the ‘factory floor’ staff are qualified to assemble any type and variation of showers sold. At each bay a specific type of assembly and quality test are carried out with each ‘factory floor’ member assigned to and trained in a specific assembly operation and specific bay that cannot move between bays. All bays are visited for the assembly to be complete but the sequence of bays visited depends on the variation of the shower being assembled. See table 3 for the showers assembly route/ sequence.
• The analysis of the data collected showed that at each bay the time taken was on average 35 minutes regardless of the type of shower or shower variation.
• The 4 workers at the assembly cell have rotating lunch breaks, with workers 1 and 2 breaking up for lunch at 12:00pm-1:00pm, worker 3, 12:30pm-1:30pm, and worker 4, 1:00pm-2:00pm.
• After the assembly is complete, the completed showers are sent for testing. Although tests are carried out at each stage of the assembly process, the company would like to test again because this is how they have always done things and for their own confidence that their products are suitable for consumers as returns due to technical problems can be very costly. There is only one test bay which is manned by one ‘testing’ operative who has her lunch between 1:30pm-2:30pm. During her lunch break the yard operative covers for her. The average time each test takes between 40 and 60 minutes.
• The main problem is that one of the production job shops based in Midlands faces an order fulfilment problem.
• The job shop production facility consists of 3 areas, Area 1 for loading of arrived orders, Area 2 for processing and Area 3 for dispatch and delivery. See Figure 1 for the shop floor layout.

|The Coursework Tasks
For this piece of individual coursework, you are required to apply simulation modelling to deliver the tasks below:
Task 1- After reading the scenario above, provide problem brief, main aim, objectives, tools and techniques, and key performance indicators.
Task 2- Use the tabular form to define and analyse the Mero shower manufacturing problem. This analysis includes decomposing the system being investigated into its main components including entities, attributes, activities, state variables, and events.
Task 3- An appropriate flowchart with detailed explanations.
Task 4- An appropriate Activity Cycle Diagram (ACD) with detailed explanations.
Task 5- Develop a business simulation model for 200 parts to imitate the above manufacturing problem
(“As-Is” situation) in order to increase productivity of the produced shower final products. Five simulation runs are required, at least two experiments (scenarios) to achieve a reasonable: i. Overall simulation time.
ii. Queue size at each. iii. Average waiting time. iv. Resource(s)/ service facility(s) utilisations.
A comparison via Excel diagrams of the “As-Is” scenario with any other improvement scenarios “What-
If” is required.
Task 6- Conclusion and Recommendations for further improvement (bullet points)
✓ The Handout Date: Wednesday, 19/05/2021
✓ Online Submission – by 18:00, Monday 5th July 2021 online submission via Resit 2 AULA. The mandatory submission components are:
o A detailed report including all the required tasks 1-6, system analysis table, flowchart diagram, Activity Cycle Diagram (ACD), both ‘As-Is’ & ‘What-If’ simulation models/ snapshots & other relevant comparison diagrams (outlines are provided above).

2. Please notify your registry course support team and module leader for disability support.
4. The University cannot take responsibility for any coursework lost or corrupted on disks, laptops or personal computer. Students should therefore regularly back-up any work and are advised to save it on the University system.
5. If there are technical or performance issues that prevent students submitting coursework through the online coursework submission system on the day of a coursework deadline, an appropriate extension to the coursework submission deadline will be agreed. This extension will normally be 24 hours or the next working day if the deadline falls on a Friday or over the weekend period. This will be communicated via email and as a CUMoodle announcement.
6. Students are reminded of the requirement to comply at all times with CU’s Academic Conduct policy & procedures. Further details are available via the Student Portal on the CU website and
|in the Student Handbook.
– Assessment Criteria
The following criteria will be interpreted appropriately according to the nature of the assessment and the general framework set by the module aim and learning outcomes.

|Feedback and Support Method: Individual written feedback to be provided on Moodle/AULA:
A slot of time will be allocated to provide students with a brief on all the assignment elements. Students are welcome to contact the lecturer during his contact hours/ THETA hours for any further assistance. However, there is a clear marking scheme/ direction on the bottom of this coursework directing students on how to prepare and manage their outputs for best achievement.
