Prepare a schedule that minimizes the total number of drivers needed and minimizes the amount of slack capacity. In case of ties for assignment, it is preferred to give weekend days off. Identify the slack capacity for each day of the week. In addition, please identify the number of people working less than full-time (i, e., working less than five days a week.
This is employee scheduling program.
No employee can be off on Friday and please do not change the requirement in the question. Thank you.

- Ali is a student in XYZ university. All wants to apportion his available time of about 600 min. a day between work and play. He estimates that play is twice as much fun as work. He also wants to study at least as much as he plays. However, Ali realizes that if he is going to get all his homework assignments done, he cannot play more than 4 hours a day. How should Ali allocate his time to maximize his pleasure from both work and play? a. Formulate a linear programming model for this problem. b. Solve this model by using graphical analysis.arrow_forwardA manufacturing plant produces a product 'A' that requires one unit of 'B' and ½ unit of 'C'. Each unit of 'B' is comprised of one unit of 'D', two units of 'E', and one unit of 'F'. Each unit of 'C' requires ½ unit of 'G' and three units of 'H'. The manufacturing lead times for the components are as follows: 'A' - two weeks, 'B' - one week, 'C' - two weeks, 'D' - two weeks, 'E' - three weeks, 'F' - one week, 'G' - two weeks, 'H' - one week.

It requires 8 hours to produce one lot of shag carpet and 6 hours to produce one lot of sculptured carpet. The company has the following production goals, in prioritized order: (1) Do not underutilize production capacity, which is 480 hours. (2) Achieve product demand of 40 (100-yard) lots for shag and 50 (100-yard) lots for sculptured carpet. Meeting demand for shag is more important than meeting demand for sculptured, by a ratio of 5 to 2. (3) Limit production overtime to 20 hours. a. Formulate a goal programming model to determine the amount of shag and sculptured carpet to produce to best meet the company’s goals. b. Solve this model by using the computer.arrow_forward
