3.4. Cost Analysis Formulation
4. Lean Planner System-Phase I [Proposed MRL Heuristic Method]
Step1: | Arrange the requested list L of (Plan-A) according to the serviceable locations in an ascending according to specific layout. |
Step2: | The route starts from the feeding source point to the first location in L |
Step3: | The serviceable all in (Plan-A) list is subject to one of previous published methods (such as: S-Shape, Mid-point, Return, L-Gap, Return, Composite or Ascending) and uses the same method that have minimum route to service in (Plan-B) that id in the same proposed direction and stops at the last one in the last avenue, then goes to step 10. |
Step4: | Resolve serviceable (which are on the proposed route) items in (Plan-B) and considers last is the starting point, and keeps the previous calculated distance route in variable via the same published method stated in step 3. |
Step5: | If there are not on the proposed route, a backlogs list is created for them |
Step6: | is the distance between the current location I and m, where m is the first serviceable location in the next avenue, according to the list L of (Plan-A). is the distance between the current location j and n, where n is the last serviceable location in the next avenue, according to the list L of (Plan-B), which is based on resolving the new distribution of serviceable on the same route. |
Step7: | If the is not on the (Plan-A) route, and needs to reverse its direction, it must be subject to the step 7 analysis. |
Step8: | If , select (Plan-A) items branch and neglect (Plan B) items to backlogging after completing all (Plan-A) proposal items , or carry out hybrid modification of items into (Plan-B) and merge the suggested routes. |
Step9: | If min [( > + )] < y, reverse the sequence of the next avenue in list L. |
Step10: | Continue serviceable the next item in L, then go to step 3 again. |
Step11: | Go back to the front avenue, then go to the feeding source point. |
4.1. Performance Measure
4.2. Illustrative Example for implementing MRL-SA ( Distribution)
4.2.1. Lean Planner System—Phase-I: Route Based on the Proposed MRL Heuristic
- Step1:
- Arrange the locations list in an ascending order L = (3, 8, 12, 16, 19, 23, 29, 45, 50, 54, 67, 75, 80, 84)
- Step2:
- The plan aims to go from the feeding source point to the location (the distance = 3 units)
- Step3:
- The plan aims to service all in the current avenue, and stop at the last in the same avenue in this illustrative example (the distance = 3 + 5 + 4 + 4 = 16 units).
- Step4:
- Calculates the distance between the location (, ), which is 20 units, and (, ), which is 10 units to arrive at the same location (Plan-A). [Take into account costs analysis equations]
- Step5:
- The direction will reverse locations in this avenue because 10 < 20, and go to location (the total distance = 16 + 10 = 26 units).
- Step6:
- The proposed plan will collect from locations , , and the total travelling distance at end of this avenue is = 16 + 10 = 26 units.
- Step7:
- At t’, the location is added to the layout and placed on the track route. Therefore, there is no need to use cost analysis equations and continue with the MRL method.
- Step8:
- Calculates the distance between locations (, ), which is 11 units, while the distance between (, ) is 20 units. [Take into account costs analysis equations]
- Step9:
- The track route will follow the ascending arrangement and go to location 4, because 11< 20. Therefore, the travelling distance = 37 + 11 = 48 units.
- Step10:
- The track route will collect from the locations , , and continue on route (the total distance = 48 + 4 + 5 = 57 units).
- Step11:
- Calculates the distance between locations (, ), which is 21 units, while (, ) is only six units. [Take into account costs analysis equations]
- Step12:
- The direction will reverse the ascending arrangement, because 6<21, and go to location (the route distance = 57 + 6 = 63 units).
- Step13:
- At t’, location is added to layout (Plan B), but not effects on direction because it between two terminal locations (, ). Therefore, this location will be serviced on the track route.
- Step14:
- The proposed route will serve locations , , , and the route distance will reach = 65 + 4 + 9 = 78 units.
- Step15:
- Calculates the distance between the locations (, ), which is 12 units, while (, ) is 19 units. [Take into account costs analysis equations]
- Step16:
- The route will follow the ascending arrangement, because 12 < 19, and go to location . Therefore, the route distance = 78 + 13 = 91 units.
- Step17:
- The proposed plan will collect from locations , , and the total route distance = 91 + 5 + 4 = 100 units.
- Step18:
- The proposed route direction will return to the front avenue and back to the main upstream source distance = 100 + 16 = 116 units.
- Step19:
- The proposed route will return to the feeding source point and the route distance = 116 + 12 = 128 units.
