MetadataShow full item record
A general purpose software package was developed to perform nonlinear constrained optimization of user-defined engineering design problems of significant complexity using desktop computers. The package, designated Microcomputerbased Design Optimization Tool (MDOT), will accept nonlinear functions of up to ten variables, which may be bounded, with as many as fifty constraints. It was implemented on a Hewlett-Packard Model 85 microcomputer with 32 Kbytes of random access memory. MDOT employs the method of feasible directions for constrained optimization, and a variable metric method for unconstrained functions. It is interactive, provides for monitoring the optimization progress, and can be interrupted to restart from a new point in the design space. Typical applications of MDOT are in the design of machine components, composite laminates, and piping systems.
