UNIVERSITY OF HERTFORDSHIRESchool of Physics, Engineering and Computer SciencePage 3 of 7Assignment BriefingSCENARIO: You need to design the assembly line and warehouse layout for the Tesla Model 3 rearbrake hub, knuckle and suspension. Assume that the facility is separate from the rest of the Teslafactory, and that the parts will be delivered to the facility (see appendix 1), and after being assembled,be shipped to the Tesla factory.Part of your consideration is that you will need to hire a building to do this, and you need to design alayout before selecting an appropriate building. You are considering a number of square buildings ofdifferent sizes available to you and you wish to hire the smallest building possible to minimize on rent,heating, lighting and other costs. Both the assembly line and the warehouse layout need to be in thesame building, separated by a STRAIGHT wall. Moreover, you also need to consider the ongoingcosts of running your forklift truck(s) inside the plant.Thus, for this assignment you are to design the assembly line layout and adjoining warehouse layout,as well as each work station’s layout (according to the demand stated below) for a Tesla model 3’srear axle assembly for the parts shown in appendix 1, based on a demand for parts for 200 vehiclesa day.For this process, assume that:Stations 1, 2 & 3A & 3B (represented below) assemble their sub-assemblies in parallel at the samerate, which are combined at station 4. Completed assembles are then transported to the warehouse. FORKLIFT TRANSPORTSTATIONOPERATORSTATIONFORKLIFTTRANSPORT Your aim is to design a layout can accommodate your process that:♦ Has the smallest overall size♦ Minimises operator walking♦ Minimises distance travelled by forklift trucks which carry the palletsYour submission should consist of the following:Part 1 – Layout Drawing – PDF DocumentPart 2 – Part B – Logic and Theory Behind the design 1x PowerPoint (.ppt or .pptx file) OR a pdfdocument .

Assume you’llneed 3 trolleys per subassembly for this purpose.♦ Assume each trolley / shelf has a capacity of 4 subassemblies.It is not necessary to show the detailed layout of the actual assembly stations – simplyindicate its footprint. You should arrange your part storage around these areas allowing forconvenient access (i.e. minimum walking) to the parts and the workstations by the assemblyworkers. Assume that each assemblystation has a footprint of2mx3m (includes workbenchand standing area): B) The layout of the warehouse with appropriately sized areas for each part, assuming:♦ Maximum of one delivery of parts each week (Mon – Friday) – assume that each deliveryfor a part might be on ANY day of the week and might vary from one week to the next.Also assume different parts might be delivered on different days.♦ ONE shipment of completed assembles leaves the facility each day at the end of the shift.♦ Left and right completed assemblies can be packed into identical stillagesinterchangeably.See Appendices for part dimensions, capacities etc.UNIVERSITY OF HERTFORDSHIRESchool of Physics, Engineering and Computer SciencePage 5 of 7C) You will need to develop a strategy for transporting PARTS ON PALLETS (ONLY). On yourdrawing, show the precise route of travel of your transporter for each part / assembly / empty palletbeing transported.On your layout, show each route of travel in a different colour as appropriate and label the route oftravel.Assume that for each pallet of PARTS the forklift needs to:Weekly:♦ move the pallet from the delivery truck bay to its location in the warehouseAs required:♦ collect the part from the warehouse♦ deliver to the assembly line♦ dispose of empty pallet in the warehouse.Part 2 – Logic and Theory Behind the design and outcome.This should consist of 2 parts:A. In this section you have the opportunity to explain to the markers the logic and theory you’veused in creating your design (for example how you have endeavoured to minimise Ohno’swastes).B. Calculate the monthly distance travelled by the forklift truck (s) which transport parts onpallets. You can ignore transportation on small parts in boxes. Show your assumptions andcalculations. Suggestion: use a spreadsheet.C. State the overall minimum size of the layout you have designed.You have a choice on how to submit this:♦ As a narrated PowerPoint presentation – maximum 5 minutesOR♦ As a PDF file – Maximum ONE A4 page explanation (Arial font size 12) and Maximum TWOA4 pages calculations / spreadsheet printout. Total Three pages Max.This will be marked alongside your drawing from Part 1, so you do not need to redraw parts of yourdrawing. Simply refer to clearly labelled points on your drawing as needed.UNIVERSITY OF HERTFORDSHIRESchool of Physics, Engineering and Computer SciencePage 6 of 7General Notes, Requirements and Constraints:1. In the warehouse, show each location for parts as an appropriately dimensioned andlabelled area.2. In the warehouse, show the location for completed assemblies in appropriately sized anddimensioned area.3. Provide an area 20% larger than one day’s production for completed assemblies in thewarehouse where they will await shipping4. Provide transportation for the completed assemblies from the final station to thewarehouse.5. Assume that loaded pallets can NOT be stacked. Assume that boxes can be stacked /put on shelves 2 boxes high.6. Aisles should be a minimum of 3m wide to allow for forklift access.7. Assume that (for security reasons), you wish to keep the warehouse area separate butadjoining to assembly area, with a 4m wide doorway in a STRAIGHT wall that separatesthem. The position of the doorway can be anywhere along this wall.8. Assume that the warehouse area has a loading / unloading area adjoining the streetwhere delivery vans / small lorries can reverse into, of 5m wide x12m long9. Assume that the footprint of each pallet is 1m x 1m10. Assume that empty pallets can be stacked up to 10 pallets high – provide an area forempty pallets in the warehouse, assuming that they are cleared after the end of eachshift. This is done by an external contractor who will (using their own equipment) movethe pallets from this storage area in the warehouse to the loading / offloading bay.11. Assume that boxes / pallets are unpacked by the operator directly at the assemblystation.12. Clearly show the outside boundary of your area needed as a thick dashed line. It is notnecessary to draw details of the actual potential building13. It is not necessary to make provision for rest areas / toilets office space. Assume thatthese are catered for on a raised area which you do not have to draw.14. Assume that completed assemblies are placed on stillages. Assume that TWELVEcompleted assembles can be placed on each stillage at station 4. Assume that thestillages for this (similar to the one below) – dimensions 1mx2m are recycled on anongoing basis between your assembly operation and Tesla. At the end of each shift, allthe full stillages are shipped to Tesla, and replaced with empty ones ready for the nextday.https://www.stillagesandcages.co.uk/non-standard-designs/.UNIVERSITY OF HERTFORDSHIRESchool of Physics, Engineering and Computer SciencePage 7 of 715. Assume that there are no quality problems from suppliers or in the operations16. You do not have top specify emergency exits or fire escapes
