( EOQ

stands for Economic Order Quantity.

( EOQ

model is a technique to find out optimum order quantity generally by considering cost of procurement, inventory holding, and backorder.

fundamental assumption of an EOQ model is that 100% of items in an ordered lot are perfect.

( |he

assumption may not be valid for most of the production processes because of process deterioration or other factors.

( |his

„ project develops an EOQ model for that each ordered lot contains some defective items and shortages backordered.

( |his

( It

is assumed that 100% of each lot contains some defective items which are collection of imperfect quality and scrap items.

„   genetic algorithm repeatedly modifies a population of individual solutions.

( At

each step, the genetic algorithm selects individuals at random from the current population to be parents and uses them produce the children for the next generation.



 



( Selection

Ȃ Select the parents from initial population based on their fitness value.

( Crossover

Ȃ Combine two parents to form a new child.

( Mutuation

Ȃ Apply random changes to a parent to form new child.
