Efficient Production and Assembly Planning
Budget: €8 – €30 EUR
16. Production Planning
Objective
The elaboration on this point should answer the following questions:
How many machines and assembly places do you need from which kind? Please consider a reasonable OEE and (if you produce multiple products on one machine) the setup times for the different products with respect to the planned lot sizes.
Which requirements (specifications) do the machines need to fulfill? Select suitable machines --> internet/catalogue research
If you need specialized machines or equipment that have to be especially designed for your application (e. g. assembly stations) please make qualified assumptions about the costs and process times.
What is the assembly sequence? What are your assembly steps? Show the value chain in form of a flow chart for the inhouse production. Note: There are many different options for the design of your assembly processes:
You have several numbers of similar assembly stations. On each station you assemble one product from all single parts to the final product.
You have a assembly line where one main part is forwarded an on every assembly station 1 or a few parts are added to the main part
You have assembly stations for sub-components (pre-assemblies) and a station for the final assembly.
... or you have a mixture of those extreme examples.
Show, how you want to realize your assembly in the flow chart and explain, which parts are added in which operation.
Necessary input data
Yearly production volume
Manufacturing technologies
Assembly technologies
Shift/Working time model
Applicable methods and tools
Calculation of necessary takt time
Selection of suitable machines
Estimation/Assumption about necessary production time per piece
Assumption of a reasonable OEE
Definition of Lotsizes (if necessary)
Calculation of necessary machinary
Assumption of assembly times and equipment
Expected results
Table with necessary manufacturing times per piece an the referring calcluation
Table with the necessary number of machines and the referring calculation
Flow chart for the assembly operations including necessary assembly times and workforce
Table with the necessary workforce
An exact floorplan / factory layout is not necessary.
