| Problem 3.5 | ||||
| Approach 1: define flow unit as # of bagels | ||||
| Resources | Which flow unit(s) demand(s) this resource? | Demand (# of bagels per day) | Capacity (# of bagels per day) | Implied Utilization |
| Worker 1 at Raw Bagels Station | All three - grilled veggie, veggie, and cream cheese | 180 bagels = 30+110+40 | 200 bagels = 10 hours X 30 bages per hour | |
| Worker 2 at Cut Station | ||||
| Worker 3 at Grill Station | ||||
| Worker 4 at Veggies Station | ||||
| Worker 5 atWrap Station | ||||
| Approach 2: define flow units as minutes of work | ||||
| Resources | Which flow unit(s) demand(s) this resource? | Demand (# of minutes demaned from this resource per day) | Capacity (# of minutes per day) | Implied Utilization |
| Worker 1 at Raw Bagels Station | All three - grilled veggie, veggie, and cream cheese | 540 minutes = 180 bagels x 3 minutes per bagel | 600 minutes = 10 hours x 60 minutes per hour | |
| Worker 2 at Cut Station | ||||
| Worker 3 at Grill Station | ||||
| Worker 4 at Veggies Station | ||||
| Worker 5 atWrap Station |
3.6
| Problem 3.6 | ||||
| Approach 1: define flow unit as # of statements - this approach cannot be used here, why? | ||||
| Approach 2: define flow units as minutes of work | ||||
| Resources | Which flow unit(s) demand(s) this resource? | Demand (# of minutes demaned from this resource per month) | Capacity (# of minutes per month) | Implied Utilization |
| Admin support staff | All four groups of customers | see 1 below | see 2 below | |
| Senior accountant | ||||
| Junior accountant | ||||
| 1. For # of minutes demanded from admin support staff - find out minutes demanded from each customer group and sum them up | ||||
| For example, a statement from group 1 customer demands 20 filing + 50 writing = 70 minutes from admin support staff. The monthly demand is 70 minutes x 15% x 50 statement/month = 525 minutes per month. Continue finding minutes of work demanded by group 2, 3, and 4 customers. Sum them up. | ||||
| 2. For # of minutes capacity for admin support staff. He(She) works 8 hours a day and 20 days a month, which should be translated into minutes of work per month. |
3.7
| Problem 3.7 | ||||
| Approach 1: define flow unit as # of cars - this approach can be used here, why? - each flow unit requires the same amount of work from one resource (different from 3.6) | ||||
| Resources | Which flow unit(s) demand(s) this resource? | Demand (# of cars requesting each resource per day) | Capacity (# cars that can be processed per day by this resource) | Implied Utilization |
| Washing machine | All four packages (groups) of customers | total demand from pakage 1,2,3, and 4 per day (in cars per day) | capacity of the washing machine per day (cars per 12 hours) | |
| Waxing machine | only 3 packages (2,3, and 4) | |||
| Worker cleaning wheels | ||||
| Worker cleaning inside the car | ||||
| Approach 2: define flow units as minutes of work | ||||
| Resources | Which flow unit(s) demand(s) this resource? | Demand (minutes of work demanded per day) | Capacity (# of minutes available per day) | Implied Utilization |
| Washing machine | All four packages (groups) of customers | total minutes demanded from pakage 1,2,3, and 4 per day in cars per day | maximum available time of the washing machine per day (12 hours) | |
| Waxing machine | only 3 packages (2,3, and 4) | |||
| Worker cleaning wheels | ||||
| Worker cleaning inside the car | ||||
