To meet the requirements of having sufficient personnel in every hour in most cost effective way, it is required to have some part time personnel in different hours as per demand. There is another option to have overtime. There are some data with constraints given in the case study based on which we have to find the best labor schedule with the minimum cost

Constraint

Part timer employees must be less than 40% of the total workforce. Full time employees work 8  hour shift, including 1 hour lunch break for 35 productive hours. They can work no more than 5 hours overtime per week. Part time employees must work at least 4 hours and no more than 7 hours without any lunch break. 50% of full time employees go to lunch in the periods of 11-12 Am and the other 50% 12-1 pm.
