Abstract : A mathematical model was developed and employed to determine the productivity of materials handling systms comprised of two or more serial handling operation . It was the object of this study to take certain measurable characteristics of each system carrier operating independent of system-induced delays and to combin thes c aracteristics mathematically to predict the productivity of the over-all system. A hypothetical relationship between operator work rate and a variable which defines the syste state was advanced and subsequently studied experimentally. An analytical study of the productivity of a simple system comprised of two serial handling opera ions was done using relationships which approximated the experimentally confirmed operator work rahareristics. Explicit solutions were obtained for this most mple e and the effect of system variables upon productivity was discussed. A method ws demonstrated for using the explicit solutions obtained for a system of two eri l m terials handling operations to predict the productivity of systems involving more than two handling operations.
