Yes, weather-related issues that affect downstream design can be modelled by Taro. From a modelling perspective, in the majority of cases it is adequate to define a single repair distribution to cover the repair time for the entire system; especially when referring to refineries and petrochemical plants. However, in some cases such as remotely operated pumping stations, the repair distributions may have wide seasonal variations.
To accommodate this need, a method of defining seasonal distributions has been introduced to Taro. Seasonal distributions may be used for the repair parameter of unscheduled failure modes, scheduled elements or conditional elements.
