Optimized Planning and Scheduling of Pressure Equipment Inspections at Comah Establishments.
In a process establishment, where the legislation on the control of major accidents hazard (COMAH) is enforced, the operator's duties include the implementation of a Safety Management System, which addresses all the procedures significant for safety. A critical issue of the SMS is the planning and the scheduling of mechanical integrity inspections on pressure equipment. This is due to high number of components - including pipes, unfired and fired vessels, pumps and valves, - which could require different technical and organization procedures for testing or inspection. Usually, mechanical integrity inspections may request higher resource use than other safety related activities. The paper presents a model for inspection planning and scheduling, in order to integrate safety issues with other technical and economical issues.
With the prevalence of data online, consumers increasingly shop not only for the product that best fits their needs, but also for the best time to purchase the product in order to reduce its cost. In line with this behavior, ecommerce websites often not only offer products, but also provide analytics based statements and recommendations relating to the best time to purchase a perishable product (e.g., air travel). This study examines the effects of such purchase timing statements and recommendations on consumers’ trusting beliefs in the recommendation facility. Our theoretical background comes from Toulmin’s (1958) argumentation model and the literature related to the role of explanation facilities in enhancing consumers’ trust. Results from our pilot study show evidence for the different roles Toulmin elements have, serving as explanation facilities in the context of predictive analytics.
