Hello,
Im working to minimise the total cost incurred to retailer by finding optimum value of maximum inventory level using Genetic algorithm. Im considering 4 subcosts (procurment, holding, expiry, lost sales) which have fixed rate (per unit qty). I have to do this over a time period (x days). Ive already done it over different time duration (1 month, and 3 yr). Each day in this time period has pre-determined demand (ie. units sold), taken from CSVDemand file.
How to conduct "senstivity analysis"? I tried searching and understood that i should record changes in result based on the changes in GA parameters. However, on varying the mutation function, selection function, mutation rate, population size, etc im getting the same results. No variation. Is that because of only 1 optimisation variable?
How should i do senstivity analysis then?
Ive attached the code below. TCFunc is the Objective function. GA_1 is the GA code. it was made with help of optimtask insert.
please provide some guidance.Hello,
