constraint problem would be good to be answered

B. The case study The nurses answering telephones in a healthcare call centre are expected to speak to 5 patients each per hour. The service operates between 9am and 5pm. As many patients call in their lunch breaks the service is busiest in the middle of the day. - The table below indicates the average number of customers by time period. Time period No. of patients Time period No. of patients 9 am 10 am 50 1 pm - 2 pm 90 10 am - 11 am 60 2 pm - 3pm 80 11 am - noon 70 3 pm - 4 pm 70 Noon - 1 pm 80 4 pm - 5 pm 50 - The call centre can employ up to 10 full-time nurses, and it has many nurses willing to take part time shifts. Part-time nurses work 4 hours a day if they are requested to work at all, and can start anytime from 9am to 1pm. They earn 10 per hour. Full-time nurses work 8 hours from 9 am to 5 pm and are entitled to one hour break where half the full-time nurses take a break at noon and the other half at 1pm (if there are an odd number of full time nurses then the higher number of nurses have a earlier break), they earn 90 per day. For consistency there must be at least 5 full time nurses working each day. You have been asked to design a roster to minimise the total workforce cost. B.
