Facility

Is defined as an element of the foundation, structure, housing or containment systems of an Operation where a loss of function; • will expose people to a risk of harm, or • will expose the environment to a risk of harm, or • will harm the performance of a production or service process. A Facility is generally not directly involved in the transformation, transfer or storage of a product or service. Hence a Facility is not directly identified in any of the business structure flowcharts, but should be identified on an appropriate site layout drawing. A graphic representation of the flow of steps within a process. In the OPERATING MODEL design two types of flow sheets used. The first is the flowsheet describing a Production process, where the steps comprise transformation, transfer and storage activities, it also indicates the inputs and outputs of the process. This type of flow sheet is referred to in Set Performance Targets. The second type of flowsheet is that used in to describe the OPERATING MODEL processes themselves. In these flow sheets the steps comprise the actions and decisions inherent in the OPERATING MODEL design. Flow Sheet

Independent Variation

The component of variation in an observed result that has been caused by factors inside of the process being observed, ie variation arising because of the process; design, operator influence, equipment performance, etc.

Operation(s)

The separable elements of a Regional asset portfolio. That is, decisions about investment in, or divestment of, an Operation can be substantially independent of such decisions about other Operations within the Regional portfolio. For example: • Mines, • Process Plants, • Power Generation Plants.

Monte Carlo Simulation

A method of calculating results for systems that have many variables, with differing degrees of independence and inter-dependence between the variables. Such systems do not lend themselves to deterministic modelling. The approach
