Data for better maintenance plans and investments policy.Application: Mills can use this information to improve their existing data collection systems and process efficiency. It also helps to set requirements for new systems. Operations managers See datacenter manager. in the capital-intensive pulp and paper industry The global pulp and paper industry is dominated by North American (United States, Canada), northern European (Finland, Sweden) and East Asian countries (such as Japan). Australasia and Latin America also have significant pulp and paper industries. are under pressure to achieve a high return from assets employed. Cash flow and return on assets Return on assets (ROA) Indicator of profitability. Determined by dividing net income for the past 12 months by total average assets. Result is shown as a percentage. ROA can be decomposed into return on sales (net income/sales) multiplied by asset utilization (sales/assets). are indicators of a company's performance, This translates into a requirement for maximum a machinery uptime. New maintenance concepts such as total productive maintenance (TPM (1) See TP monitor. (2) (Transactions Per Minute) The number of transactions processed within one minute. See TPS. (3) (Trusted Platform M ) rely on collected maintenance data. Implementation of a systematic reliability program has achieved remarkable savings without major investments. This paper describes a new Internet-based maintenance data collection application and its use for improved maintenance planning at a U.S. woodyard. It presents sample data collection results and demonstrates how the availability performance measures based on the collected data are calculated. The developed data collection application met the user requirements. The device-based data structure makes possible further analysis, reporting, and data use. The database, from which maintenance and failure data can be recalled, supports maintenance information exchange and helps to solve recurring re·cur intr.v. re·curred, re·cur·ring, re·curs 1.

Detailed analysis of availability performance helps to find bottlenecks in production line and insures that corrective measures are directed to the right objects. The information boosts the efforts to increase production line efficiency and supports decision-making for new investments. By systematic analysis of the improvement potential and by good collaboration between woodyard personnel and the machinery manufacturer, this become possible.
