You can be involved in healthcare, you can be involved in humanitarian levels, through to quite heavy engineering for dams and things like that, which can physically change people’s lives.
Others, for example the painting bays, were left as flexible station areas to allow recording of the capacity over time.. Other input data included:.truss parameters, such as type, dimensions, and other product data.
production schedules, to specify the order in which truss types would be made.throughput and timing data, such as processing times of stations, speed of conveyors and speed of cranes..The data itself was not hard-coded into the model and instead read from an external data file, which made running multiple simulations for differing parameters a rapid process.. Several different scenarios were simulated in the model that were made up from combinations of options.
This included different production schedules and whether transport timings were included, to test sensitivity of the system to these inputs.We also added scenarios for a +/- 20% variation on process timings (for example, the welding stations), using a triangular distribution.. We defined key outputs to measure performance of the system, including schedule completion time (i.e.
how long it took to manufacture all trusses in the schedule) and average daily throughput, for comparison against expected market demand.
We recorded buffer accumulation to test for process bottlenecks, as well as the number of occupied painting stations to check capacity against what had been previously assumed.. Case study - modelling conclusion.Use low impact materials by considering the environmental impact at specification stage, alongside cost and technical considerations.
This also includes the manufacturing location of materials and the transportation distance to site..The recycled content of materials should be maximised without significantly impacting the technical characteristics of the material..
Designing out waste can be achieved with clever and simple use of materials, eg.altering the centre point of ceiling tiles to limit offcuts to a single side of the room, rather than both sides..
