001 Basic Scenarios:
001-01 Service Capability:
1. lift capacity? e.g.: 20 person or 1500kg;
2. peak time? e.g.: 07:00 - 10:00 (Monday - Friday)
3. Maintance time? two lifts differ time(monthly)
4. rest time, or both run 24 hours?
5. location place? shopping mall / office / factory ...
001-02 ***Running Logic***:
1. run logic follows 'time efficiency' -> quick response time;
2. run logic follows 'load efficiency' -> max weighing capacity;
e.g.: life A is on 8 floor - move down, has 3 person inside, lift B on 6 floor stop, no person inside;
people at 5 floor pressed '1' button;
- this case for case1 & case2 there should be differ reaction for lift A & B;
3. run logic follows 'power efficiency' -> save power(energy);
4. run logic follows 'speed control';
e.g.: lift up from '1->8' differ from '1->2->3->8'?
5. load balance while two lifts work simultaneously;
6. load balance while one lift stopped work;
7. control logic -> reactions from 'inside or outside' of the lifts;
002 Special Requirements:
1. lower button for disabled people -> priority;
2. security & operate with authorized card/key;
3. user manual declare all functions and security points;
4. ventilate & cell signal inside of the lifts;
003 KPI:
1. the amount of time lift move between each floor;
2. the amount of time lift wait while open&close lift' door;
3. cases 1-2 meet specification while lifts approach the limit of weight capacity;
4. cases 1-2 meet specification while lifts kept working long time, such as more than one year;
004 Abnormal cases:
1. lift running while no power;
2. warnning while lift 'over weight';
3. warnning while lift's door open too long(time);
