System and method for performing simulations of uncertain future events

A simulation method performed on a computer system having a processor and memory and a plurality of lines of computer code, the method comprising:

• receiving a first task probability density function that indicates a range of probabilities for a characteristic of the first task;
• receiving a second task probability density function that indicates a range of probabilities for a characteristic of the second task;
• selecting, by the computer system, an operation that combines the probability density function of the first and second tasks;
• assigning a random number to the characteristic of the first and second tasks, respectively and generate a random characteristic for each of the first and second tasks;
• performing an addition operation of the random characteristics of the first and second tasks if the first task occurs in series with the second task;
• performing a merge operation of the random characteristics of first and second tasks if the first task occurs in parallel with the second task;
• and
• generating an output probability density function as a result of the selected operation that represents a simulation of a completion characteristics of the first and second tasks.

• receiving a first task probability density function that indicates a range of probabilities for a characteristic of the first task;
• receiving a second task probability density function that indicates a range of probabilities for a characteristic of the second task, the first and second task having a logical association different from the characteristic of the first and second task;
• and
• performing an accelerated simulation to create an output probability density function from the first and second tasks.
