The full PETP programme was retired and superseded by a new programme, but, at the time, it provided an opportunity to develop a new type of prison environment using a platform based Design for Manufacture and Assembly (DfMA) approach – one whose core purpose was to increase the likelihood of rehabilitation and reduce re-offending rates.
The truss system design is an automated, digital workflow which takes client requirements including geometrical constraints and preferred materials, and uses iterative parametric 3D modelling to develop individual truss designs.Structural optimisation and validation are included as part of this process to ensure that the truss meets the required specification.
Once complete, these 3D models become a suite of outputs which can drive further analysis of the wider system.This includes detailed analysis of parts of the assembly process, such as robotic welding cells..In addition, the mathematical modelling and simulation tools (including process simulation models) can then be used to test the proposed manufacturing process and production options, providing stakeholders with more information to make better informed decisions.. Construction automation case study: the fabrication process.
The factory takes square hollow section steel and plate steel as raw materials and fabricates different types of painted trusses.Using expected market demand as well as the ongoing truss system designs, a process flow for fabrication was developed with initial layouts for arrangement and quantities of equipment.
Most of this process is to be automated with some manual intervention for transport, quality assurance and painting; processes where automated stations are unnecessary or significantly expensive against provided benefit.. To provide a better understanding of the system, we built a time-based discrete event model to represent the process and provide key outputs for various sets of input parameters.
This allows the designers and stakeholders at an initial planning stage to see, digitally, how their assets could perform during production and provide feedback during the project at the earliest opportunities where large changes can be made to maximise value.. For the purposes of this project, operations upstream of raw material addition, and operations downstream of the final truss painting, were excluded from the simulation.Once all the stakeholders can understand and visualise the connections, designing a physical space unfolds.
Function comes first.. To purchase this book, visit.What came to me was not a revelation but a simple remembering.Only three weeks ago I was involved in a webinar and I remember saying “Design to Value represents an ‘and’ rather than an ‘or’…”.
The reason why it seems so hard to take choices which will protect us in the longer term is that we believe that to do so will lessen or lives, our livelihoods, our success in the short term.We feel we have strived hard to get what we have, companies and investors have got used to the revenues generated, we have all benefitted from the growth of technology and cheap energy and the offer on the table seems to involve us giving these things up; the ‘OR’ feels oppressive.. What flooded into my mind then were the many examples, some experienced personally and some simply read about, that have demonstrated that we can have our cake AND eat it.
