Today's industrial systems are becoming increasingly complex and automated. The goal: to improve efficiency, increase production, improve reliability, achieve consistent specifications and reduce incidents. However, to determine optimum system performance, one must evaluate the system over time, include the human operator as a component and evaluate performance using risk-based approaches to understand overall system performance affect. Many variables must be considered, deep-seated biases overcome and perceptions of risk and error accounted for. This paper details a risk-based analysis, using a modified FMEA approach, of an automation project to determine the appropriate level of human input to the control system.

Keywords: automation, human errors, automatic control systems, human intervention, optimisation, system performance, performance evaluation, risk assessment, modified FMEA, failure mode and effects analysis, human input

    Overview Hussain Sagar Lake in India faced an inflow of untreated waste and pollution causing decreasing DO levels and foul odors in the nearby community. An even more critical threat was eutrophication, or an excessive number of nutrients in the body of water, choking out the natural aquatic life. Given the lake is stagnate, circulation and the distribution of efficient aeration was needed to alleviate these issues. Challenge Hussain Sagar Lake is located in a recreational area with many visitors. The lake...

    This study investigates factors that influence the growth and diffusion of microorganism especially total coliform and Escherichia coli (E. coli) in water distribution networks. The experiments were carried out in a laboratory distribution network where different flow directions at junctions, varying inlet flow rates, initial chlorine doses and natural organic matter were studied. Depending on the incoming flow directions, two hydraulic behaviors were observed at cross junctions: (i) incomplete mixing and (ii)...

    To predict the membrane fouling phenomena in the membrane filtration operation, the individual models derived from Darcy's law and the corresponding combined models were employed to investigate the kind of models that provided better fits. The filtration of the mixed liquid from membrane bioreactors with different sludge retention time (SRT) at a constant pressure was carried out. The variation of applied pressure had significantly effect on the kind of the individual model provided better fit for the data at...

    Man-made lagoons have been used worldwide for the treatment of domestic and industrial wastewater, it seems, forever. All waste lagoons were first designed and thoughtfully planned considering their locations, soil makeup, and waste reduction processes prior to being implemented. The biological process of organic waste reduction is always a consideration of waste lagoon designs. There are three biological concepts considered for waste lagoons - Anaerobic lagoons, commonly at least 10 feet deep, have no dissolved...

The plant is comprised of two separate secondary treatment plants (Plant 1 and Plant 2) served by a common headworks facilities and primary clarifier facilities. Plant 1 was constructed in the early 1960s and Plant 2 was constructed in the mid-1970s. Both plants discharge to a common ultraviolet (UV) Disinfection Facility and Effluent Pumping Station prior to discharge...
