Computer‐based Total Productivity Measurement:An Indian Chemical Plant

Describes a microcomputer software system for total productivity measurement in manufacturing organi‐zations, named TOPROD, developed by the author. Beginning with a discussion advocating the greater use of total productivity ratios in industry, the six main programs of the software are described. The first three modules deal with various categories of inputs: capital (including fixed and working), direct costs (such as labour and raw materials) and indirect costs. The fourth module considers all output items. The fifth and sixth algorithms compute total and value‐added productivity respectively, as well as partial productivities of the principal inputs. Describes the application of TOPROD to an Indian chemical process plant, producing high‐density polyethylene. The results are analysed, and possible steps for improvement suggested.
