Quantity

• All scheduling information for each Activity entered into the Scheduling Model. Quality

A Scheduling Model Element shall be set up for each of the Activity defined in TA MS.02 Specify Activities for Scheduling Model.

Each Scheduling Model Activity shall record the following identifying data; • the Business Structure identifier for the Activity (the identifier shall allow filtering of activities at any level of the structure), • the role accountable for the Activity, • the Activity description, and • the Work Management System Job Template identity for the Activity. Each Scheduling Model Activity shall record the following scheduling data, where appropriate; • trigger parameter, • trigger parameter start value (to identify where in the life cycle of an activity the forecast commences), • trigger value (the point at which the activity is scheduled), • trigger tolerance (earliest and latest schedule points around the trigger value), • constraints on scheduling (e.g. operating, down, full, empty, access), • scheduling commencement date (for activities that will only commence active scheduling at some time after the forecast commences), and • scheduling termination date (for activities that will only cease active scheduling at some time after the forecast commences). Each Scheduling Model Activity shall record the following performance data, where appropriate; • Work Package duration,

• utilisation, • availability, • operating rate, • quality rate, • efficiency.

To cater for the situations where variability in a parameter will be significant in determining the confidence of meeting performance targets for a process, the model must allow a probability distribution to be entered for the parameter. The probability distribution for a performance parameter shall, as a minimum, be defined by; • the values of the minimum, maximum, mean and mode of the distribution, • the 'shape factor' (i.e. spread of the distribution - e.g. standard deviation), In cases where the variability in the parameter will not be significant in determining the confidence of meeting performance targets the model shall use a mean value only.
