A highly configurable and flexible water network management advisory tool for optimal operational and resource planning.
With MISER, a number of UK water companies have demonstrated 10% potential cost savings per annum on their energy and chemical expenditure. Specifically, MISER helps water companies to:
Models are user configured via a schematic interface, using a broad range of component and user-defined objectives and constraint types. The MISER advisory tool can be installed and operated locally or via a cloud service, and once trained, users can configure MISER independently with expert training and support provided by Servelec Technologies' team of skilled technicians, engineers and developers as required.
MISER's core function assists with monthly production planning and budgeting to plan source outputs, reservoir levels and key transfers over the medium-term based on user-configured objectives, expected demand, droughts, outages, current stock levels and seasonal variations in cost. Analysing a range of timeframes, MISER minimises costs, taking into account all expenditure between source and tap while maximising security of supply.
Offline pump and valve scheduling optimises energy costs via tariff management and pump performance within user-defined constraints.
Water Resource Modelling is used for preparation of water resource management plans which derive surface water deployable outputs under specified levels of service, taking account of drought control measures, demand restrictions, reservoir storage projections, conjunctive yields and climate change scenarios.
During a failure, MISER extends the period of time before customers are affected and minimises the final number of customers impacted. It also models the consequences of outages, for example for capital maintenance planning.
The optimal scheme selection tool for investment planning takes into account scheme phasing, TOTEX and supply-demand balance at minimum NPV cost.
The strategic risk module incorporates Monte Carlo simulation to take account of uncertainty in forecasts by using randomly generated optimisation parameters, rather than pre-determined constraints. Optimisations are performed over many trials in which demands and inflows are sampled from user-defined statistical distributions.
Telemetry Linkage for validated data import for automatic initialisation of the model.
Source tracking can track the flow of water through the network to identify populations which might be affected by a source contamination incident. MISER identifies which demands are fed by each source, and which source feeds each demand, so that the impact of different operation and investment options on customer water quality can be seen. Additionally MISER can identify which sources could potentially have caused an incident given the list of demands affected.
The PISG module generates synthetic inflow sequences that have formal significance (e.g. 1 in 100 years return period). Statistical distributions are automatically selected and fitted to streamflow data.
The time delay module is typically used for open channel flows with significant travel times.
MISER enables the creation of multiple schematic models, subsets & visualisations
