Plant load factor is a measure of the actual output of a power plant compared to its maximum possible output.

• Plant load factor is calculated by dividing the actual energy generated by the plant over a specific period by the maximum possible energy that could have been generated during the same period.

• It is expressed as a percentage and indicates how efficiently a power plant is being utilized.

• A high plant load factor i...read more

Machine availability is the percentage of time a machine is able to be used for its intended purpose.

• Machine availability is calculated by dividing the total operating time by the total time in a given period, then multiplying by 100.

• For example, if a machine operates for 800 hours in a month and there are 1000 total possible operating hours, the availability would be 80%.

• Factors like downtime, maintenance, and repairs

Dynamic Programming (DP) is a method for solving complex problems by breaking them down into simpler subproblems.

• DP is used when a problem can be divided into overlapping subproblems.

• It utilizes memoization or tabulation to store results of subproblems.

• Example: Fibonacci sequence can be computed efficiently using DP.

• Another example is the Knapsack problem, where optimal solutions are built from optimal sub-solutions.
