 Problem statement. Any methodology is based on knowledge about the problem. The  fullness  and  orderliness  of  the  base  determine  further  volumes  and  possible  options  for implementing  the  methodology.  Purpose.  To  analyze  the  existing  ways  of  machine  creations  and propose  the  new  effective  algorithm  of  machine  creation  using  the  mechanism  of  articulated disjunction. Considering the research structure and improvement of the informational and program technologies,  changes  to  the  traditional  methodology  of  machine  creation  are  made. The existing paradigm: parametric and functional performance of the machine, the design of which is improved based  on  existing  machines,  is  a  modification  of  predecessors'  parametric  and  functional performance.  Proposed  paradigm:  parametric  and  functional  performance  of  the  new  machine, improved  based  on  the  subject  area  of  technical  solutions,  methods  of  design  and  operational conditions more precisely coincide with the technological process to realize what they are called. Proposed hypothesis: there are such methodologies of design that provide an opportunity to provide rational  productivity  within  existing  operational  conditions.  Methodology.  Morphological  space  is used  to  form  qualitative  features  of  the  created  machine.  The  peculiarity  of  the  proposed methodology is that the set of features of the created machine also contains subsets of processes and phenomena in which the machine is involved. This allows assessing the compliance of the process in which  the  machine  is  involved  and  the  machine  operation  processes.  Findings  (results).  The algorithm of machine creation using the mechanism of articulated disjunction is proposed. It allows the creation of the new construction at a given sequence of stages to improve at every step in a given direction based on the determined criteria. Originality (novelty). Method of articulated disjunction, which  is  based  on  the  principle  of  formation  of  the  set  of  necessary  properties  of  the  structural elements of the machine based on a given primary criterion of machine efficiency. The essence of the method of articulated disjunction is that the sample of elements that have common features and 
properties is reformulated based on a given criterion. The proposed method provides an opportunity to determine the advantages of one structure described by various factors, in comparison with others, based on the criterion set. Practical value. The algorithm of synthesis and improvement of existing machines  allows  for  determining  their  main  quality  features  in  the  initial  stages  of  the  design  of machines.
