There is a broad range of component and constraint types which can be entered into the MISER model:
Streamflows as historical time series, with probabilistic inflow sequence generation, and flow duration and frequency analysis
Configurable licences, including rolling, seasonal, minimum/maximum, prescribed/maintained, individual/group, restricted days and conditional abstraction
Reservoir capacities, operating volumes, targets and operational/drought control rules
Reservoir levels as historical time series, for use in simplified groundwater models
Flow limits, ramp rates, losses and pump performance data
Costs, including volumetric, flow dependent and electricity tariff
Outages, describing time-related changes in capacities and pump availabilities
Blending constraints and other dependencies (e.g. flow A < flow B * 5 + 3 * Res storage Y)
Demands, future increases, global demand changes and headroom
Additional constraints using Basic Language macros, e.g. flow A = res volume ^ 3.6
Sub-models, for modelling changes to the "base" model for scenario planning
Users can add schematic features such as arrows, textboxes and backdrops, as well as embedded objects such as spreadsheets and presentations.
Timesteps of half-hourly and longer (e.g. daily, weekly), and profiling of constraints over time, are supported. A key advantage of MISER is the ability to use a single model for a range of both long-term and short-term applications, providing benefits of ease of use, model consistency and simpler maintenance.
MISER offers a range of tabulation, graphing and reporting facilities, together with import/export and printing functionality. MISER uses standard Microsoft AccessTM database technology and can be customised to extract data from or provide data to corporate databases. Development of a client-server version of Miser utilising Microsoft SQL-ServerTM is ongoing.
