Glossary
Actual Gross Weight (GW) is the actual weight of the shipment
Volume Weight (VW) is calculated based on a cargo's size, measurement or dimensions
formula for calculating Using the English System: L x W x H in inches (in.) / 165 = vw (in lbs.) Using the Metric System: L x W x H in centimeters (cm.) / 6,000 = vw (in kgs.)
Chargeable Weight of cargo intended for air shipment is the actual gross weight (gw) or the volume weight (vw), whichever is greater.
Weight Break is the point at which the weight or chargeable weight of a shipment is large enough to be assessed the lower freight rates which are applicable to larger shipments, this is as per the carrier's tariff.
Volume Cut is discount offered for voluminous cargo. It is the same concept as weight break, but has its own formula to calculate.
If you have freight that is 100 Kilos and the chargeable weight is 200 Kilos, the co-loader or airline will offer 10.00 per Kilo with a 50/50 volume cut This means that you will subtract the actual weight from the chargeable weight and divide the sum by 2. Add this total to the actual weight and this is the amount you will be paying for. (200-100)/2 = 50 + 100 = 150 Kilo's Next you will need to break this down into an actual per kilo cost. You will do this by multiplying the 150 Kilos by the rate offered of 10.00. 150 X 10.00 = 1,500.00 Then dividing the sum of this by the chargeable Kilo's to get the actual per Kilo cost. 1,500.00 / 200 = 7.50 per Kilo *This volume cut can vary and may not always be 50/50, it could be 25/75, 40/60, etc...
Minimum (Min) is the lowest amount that can be charged for the service.
Maximum (Max) is the highest amount that can be charged for the service.

Summary
We are rewriting the rate db air - Phase one - according to new simplified requirements, provided by Chikei Ho (Module Owner)
Current Business Process
Currently, Chikei has created an excel spreadsheet to maintain and search rates. Each office is sharing this spreadsheet using dropbox. http://www.dropbox.com/.
This enables each office to update their own portion of the rate sheet (all are updated on the same spreadsheet, it is shared).
It allows each office to access the other office's rates.
Dropbox is preferred because it is more secure then emailing the rates.
The first page of the spreadsheet is where all of the rates are entered. (Tab is named GCR ED)
The Second page of the spreadsheet is the Pivot table. This is where the results can be searched by selecting airport to airport pairs. (Tab is named Pivot)
Examples of spreadsheet
Spreadsheet is to large, to copy in one picture.
1st picture columns A through Q
2nd picture columns R through AC
Example of pivot table output
The table is generated with the following output by
- By selecting the Origin Airport from a drop down list in row 2 column B
AND
- By selecting the Destination Airport from a drop down list in row 3 column B
Business Requirements
Uploading of the shared excel spreadsheet into a database.
Exporting the excel spreadsheet from the database.
Each spreadsheet uploaded will replace any spreadsheet previously uploaded into the database.
Enable searching of these rates.
Output of the rates displaying all information currently shown in the output of the pivot table.
A restriction should be put on who will be able to import and export these rates. I believe this will be a done by SuperOps, but I will confirm.
Questions and Answer from Chikei
Questions are in black
Answers are in blue
1) What is the biz process for "Air freight buying rates file" upload and maintenance:
- a) Is it one file per office? (value in the first column will always be the same in one file)
- b) Is there only one file per office? (which means we can overwrite old data when uploading new version of this file)
There will be a unique spreadsheet where all the offices will use to add on their rates and share the information with the other offices. We are currently using dropbox to update, maintain and exchange those information.
- c) If operator uploads a new file should the system replace new file with the old or compare and merge line by line
Any new version of the spreadsheet will overwrite the old one. (In our dropbox folder, there will be only ONE spreadsheet)
Do want access to Dropbox and be able to see the available database in place? (including the seafreight ones)
2) Questions about fields/values:
- a) what is "TACT"
TACT stands for The Air Cargo Tariff published by IATA (International Air Transport Associations) and contains comprehensive information regarding air cargo rules, regulations, rates and charges. When the database is referring to the TACT that means the published IATA rates are to be applied.
The pivot table does not handle letters as a data so it is showed as ‘zero’ but we should read TACT which informs the operators that IATA TACT rates applied.
- b) validity from date - how is it defined
The validity date is defined by the carriers or subcontractor. Basically this information will be monitored by the office who enters the rates he is responsible for.
- c) do we need "comment" field for spreadsheet
If possible yes, this would add on flexibility. The database does not cover all the options. Having a comment field would enable to clarify possible grey areas of some rates.
- d) we suggest to add "valid from" field to Output
This suggestion is welcomed
Two points:
1)I believe that the segmentation of the airfreight rates structure will have multiple applications (in connection with Finance/Accounting/Sales). This is something we need to talk and stay in phase.
2)In a practical (or common user) point of view, the way we need the rates sorted is different from my initial expectation. Please find here attached an Excel sheet including a pivot table to share with you how I visualize the sorting function. (The Excel Sheet is uploaded into Mantis 2690)
Additional information
information added 7/26/11
Importing and Exporting the rate sheet
Importing of the spreadsheet should only be allowed to specific user groups. We need to add a section in Admin -> Users Access Admin -> where we can select which groups should be allowed to handle this.
The user groups selected to import the spreadsheet, should also be able to export the whole spreadsheet. Exporting should be the last version imported and should be in the same format as the spreadsheet that was uploaded.
Searching rates and downloading results
All internal users should have the ability to search the rates once they are uploaded.
Operators should have the option to download the search results to excel.
