Decision information systems, methods, and computer programs for better informing decisions to use multiple drugs in drug delivery devices, including implantable devices, for drug administration. Executable computer programs and logic embodying methods of the invention can calculate consistent multiple drug mixture amounts and drug delivery flow rates. One program accepts user input indicating a desired first drug dose rate, an initial first drug concentration, a desired second drug dose rate, an initial second drug concentration, and the reservoir size of the drug delivery device. The program method calculates a first drug amount and a second drug amount to combine in a mixture as well as a first drug true concentration in the mixture. The drugs can be mixed consistent with the physician's instructions using the program output. The first drug true concentration can be entered into a programmer device as the only drug concentration entered. Another program calculates a consistent first drug, second drug, and diluent amount to be added to a mixture for injection into a fixed flow rate, implantable drug delivery device. Methods preferably output true concentrations and dose rates for all drugs to be added and most preferably show all calculations used to arrive at the flow rate and mixture amount calculations. Yet another program receives a new desired drug dose rate for a previously filled device. The program accepts the existing mixture volume and true drug concentrations for a partially depleted device and calculates a new mixture flow rate to achieve the desired dose rate using the existing mixture. The methods can be implemented as executable computer programs in programmer devices, general purpose computers, servers, handheld computers, and personal digital assistants.

The invention relates to a method for adjusting concrete rheology requiring only that load size and target rheology value be selected initially rather than requiring inputs into and consultation of a lookup table of parameters such as water and hydration levels, mix components, temperature, humidity, aggregate components, and others. Dosage of particular rheology-modifying agent or combination of rheology-modifying agents is calculated based on a percentage of a nominal dose calculated with reference to a nominal dose response (“NDR”) curve or profile. The NDR profile is based on a correlation between a rheology value (e.g., slump, slump flow, yield stress) and the rheology-modifying agent(s) dose required to change rheology value by one unit (e.g., slump change from 2 to 3 inches) such that exemplary methods can employ corrective dosing based on the NDR and the measured deviation by the system.
