products heeds mdo heeds np heeds post services engineering consulting website www.redcedartech.com red cedar technology is a software development and engineering services company . red cedar technology was founded by michigan state university professors ron averill and erik goodman in 1999 . 2 the headquarters is located in east lansing mi near msu s campus . red cedar technology develops and distributes the heeds professional suite of design optimization software . heeds is based on spin out technology from michigan state university . on june 30 2013 red cedar technology was acquired by cd adapco . 3 contents 1 history 2 heeds mdo 2.1 design optimization 2.2 design of experiments doe 2.3 robustness and reliability 3 heeds np 4 heeds post 5 red cedar university 6 references 7 external links history edit red cedar technology was founded in 1999 to commercialize technology developed at michigan state university . the company initially provided engineering consulting services including non linear fea and design optimization . the optimization technology was released as a software product heeds in 2004 . 4 heeds mdo edit heeds hierarchical evolutionary engineering design system mdo is a software package that interfaces with commercial cae tools in order to automate and improve the search for better product and or process designs . heeds can perform both single objective and multi objective pareto optimization . additionally heeds includes the ability to perform design of experiments and reliability analysis . heeds mdo was formerly named heeds professional . heeds is utilized across many industries including aerospace automotive 5 6 biomedical 7 8 and manufacturing . 9 products such as nitinol stents 10 crash rails in automobiles 11 mems 12 and fiber composite parts 13 have all been designed using heeds . heeds generically interfaces with analysis codes through batch execution and different forms of scripting but also includes direct interfaces to several commonly used cae tools including abaqus ansys ls dyna 14 nastran 15 nx star ccm and microsoft excel . 16 design optimization edit when an engineer is required to design a component or system to conflicting performance criteria design optimization is often used . heeds allows the user to analyze a design based on their normal cae tools and explore different options that exist based on user defined design variables . heeds includes the sherpa algorithm which is an intelligent hybrid adaptive design optimization method . sherpa is based on over two decades of research at michigan state university and was spun off to red cedar technology in 1999 . heeds also has the mo sherpa algorithm which is an adapted version of the sherpa algorithm designed for multi objective design optimization . this gives the user the opportunity to find a set of pareto optimal designs and gain information regarding the trade offs between the objectives . the following design optimization algorithms are available in heeds 17 sherpa multi objective sherpa mo sherpa genetic algorithm sequential quadratic programming simulated annealing response surface methodology multi start local search particle swarm optimization nelder mead simplex design of experiments doe edit heeds allows the user to predict sensitivities using design of experiments . the following sampling methods are available 18 full factorial designs 2 level and 3 level fractional factorial designs 2 level and 3 level taguchi orthogonal arrays plackett burman designs latin hypercube designs central composite designs d optimal designs taguchi robust design arrays user defined arrays user defined response data robustness and reliability edit heeds has a robustness and reliability agent which allows the user to perform robustness studies using monte carlo sampling or latin hypercube sampling and reliability studies using monte carlo sampling latin hypercube sampling or form . robustness studies can tell the user how sensitive the design is to stochastic variation of the input parameters . reliability studies can tell the user how likely a design is to violate constraint limits as a result of stochastic variation of the input parameters . 19 heeds np edit heeds np is a non parametric mesh based optimization tool that is used to design structural components . 20 the mesh of the component is morphed directly by the software to meet mass or stress targets . heeds post edit view exported from heeds post v1 .0 showing a design table response surface fit plot and 3d mars surface plot from a doe study . heeds post is a post processing and data visualization suite designed to work with heeds mdo results files . 21 22 red cedar university edit red cedar university is a service provided by red cedar technology to educate those interested in design optimization . 23 references edit management team new companies boast msu roots http www.cd adapco.com blog bob ryan red cedar and cd adapco
