<p>A machinery operation involves the steps: 1) inputting into a computer statistical past-performance information representing, in relation to each job, the speed at which the machine was run, together with run length of the job, and optionally at least one or more of a) information representing the difficulty of the job; b) information representing the operator in relation to the job; c) information representing the machine utilised; d) information representing the utilisation pressure existing at the time the job was carried out; 2) feeding corresponding information representing a job to be performed into the computer; and 3) causing the computer to calculate an optimum run rate for the job to be performed, and using an equation of the general formula y = f[1-e-kx]. The calculated or optimum run rate may be used to determine the probable length of time a particular job is likely to take, or may be utilised to indicate to the operator the most appropriate speed at which the machine should be run, or both.</p> |
