Overview	Top

If the auto-calculation option is selected in the Plan, the system automatically calculates the number of containers:

• Required to start a Plan Condition, based on the factors listed below.
• Required for each Pull Task.

The Inventory Calculation determines the number of Containers required for any single Sample Pull.

Inventory calculation is controlled by these factors:

• Whole Container Pull vs. Partial Pull vs. Partial Distribution
• Number of Repeats per Test
• Required Quantity per Test Repeat including Unit Conversion
• Container Size and Units
• Requires Separate Containers per Repeat Flag
• Requires Separate Containers per Test Flag
• Destructive vs. Non-Destructive Testing Flag
• Container ReUse Flag
• Discrete Laboratories
• Contingent vs. Required Testing Flag
• Whether or not the Pull Quantity is multiplied by the Sample Count

Stability supports these inventory models:

1. Define number of Containers to pull for each individual Sample.
2. Define raw inventory required to pull for each individual Sample.
1. Supports "Partial Pulls" and pull the specific raw amount, or
2. System calculates the number of whole Containers to pull, or
3. System calculates the number of whole Containers to pull then distributes the required fractional amounts between different Laboratories.
3. Define raw inventory required for the tests assigned to the Sample. The system then calculates total inventory requirements.
   1. Support "Partial Pulls" and pull the specific raw amount, or
   2. System calculates the number of whole containers to pull, or
   3. System calculates the number of whole Containers to pull then distributes the required fractional amounts between different Laboratories.

Unit Validation is performed throughout Stability and Studies. When calculating inventory, PlanItem WorkItem Units are validated against Container Unit only when TrackItem inventory calculation converts them to Container Unit of the Study before the calculation. See Stability Unit Validation for more details about Unit Validation.

 

Calculate Required Quantity	Top

This determines the number of Containers required based on the total quantity.

To derive the total quantity, you must define these factors that contribute to the calculation:

• Number of individual execution/repeat required for a Test on a Sample. "Repeat" means how many times a particular Test would be executed for a Sample. Each additional repeat causes an additional instance of the SDIWworkItem and DataSet. Each repeat of the Test requires additional Test material.
• The quantity of material required to execute a single repeat of the Test.
• Unit of measure associated with the Quantity.
• Whether or not the Pull Quantity is multiplied by the number of Samples.

To get the total number of Containers required for the raw inventory:

1. Get the total required inventory per Test. Add all the available Tests (also considering the number of repeats for the Tests).

   Test A - 25*1 = 25

   Test B - 10*2 = 20

   Test C - 30*3 = 90

   Total Raw Quantity = 135 Tablets [25 + 20 + 90]

2. Calculate the number of Containers needed based on the Container size. Divide the total of 135 Tablets by Container Size.

   Container Size	Number of Containers Needed
   25 Tablets	6
   50 Tablets	3
   100 Tablets	2
   200 Tablets	1
   500 Tablets	1

Multiply Quantity by Sample Count

If the Sample Count is greater than 1, and the "Multiply Quantity by Sample Count" is Yes, the Pull Quantity (Quantity per Repeat) is multiplied by the defined number of Samples.

If, in the above example, the number of Samples is 2, and the "Multiply Quantity by Sample Count" is Yes the total quantity is calculated as follows:

Test A - 25*1 = 25

Test B - 10*2 = 20

Test C - 30*3 = 90

Total Raw Quantity = 135 Tablets [50 + 40 + 180] multiplied by 2 (Number of Samples) = 270 Tablets.

 

Calculate Quantity for Discrete Laboratories	Top

This calculates the number of Containers needed for separate Laboratories (Departments).

To derive the total quantity, you must define these factors that contribute to the calculation:

• Individual laboratories require their own aliquots.
• Need separate Containers to execute Tests for each laboratory.
• Number of individual execution/repeat required for a Test on a Sample. "Repeat" means how many times a particular Test would be executed for a Sample. Each additional repeat causes an additional instance of the SDIWworkItem and DataSet. Each repeat of the Test requires additional Test material.
• The quantity of material required to execute a single repeat of the Test.
• Unit of measure associated with the Quantity.
• Whether or not the Pull Quantity is multiplied by the number of Samples. See Example.

To get the total number of Containers for discreate laboratories:

1. Get the total required inventory for all the Tests per Laboratoty. Add all the available Tests in each of the laboratory (also considering the number of repeats for the Tests).

   Total Raw Quantity:

   Physical Lab	Bio Lab
   Test A - 25*1 Test B - 10*2	30*3
   45 tablets [25 + 20]	90 tablets

2. Calculate the number of Containers needed for discreate laboratories based on the Container size. Divide the total of 45 Tablets and 90 Tablets (for each laboratory) by Container Size.

   Number of Containers Needed
   Container Size	Physical	Bio
   25 Tablets	2	4
   50 Tablets	1	2
   100 Tablets	1	1
   200 Tablets	1	1
   500 Tablets	1	1

 

Calculate Quantity using Separate Containers : Separate Repeats from Separate Container	Top

This calculates the number of Containers needed for each repeats of the Tests, where execution of each Test repeat requires separate Containers.

To derive the total quantity, you must define these factors that contribute to the calculation:

• All Tests are not executed from the same container.
• Each repeat of a particular Test must execute from separate Container.
• Number of individual execution/repeat required for a Test on a Sample. Repeat means how many times a particular Test would be executed for a Sample. Each additional repeat causes an additional instance of the SDIWworkItem and DataSet. Each repeat of the Test requires additional Test material.
• The quantity of material required to execute a single repeat of the Test.
• Unit of measure associated with the Quantity.
• Whether or not the Pull Quantity is multiplied by the number of Samples. See Example.

To get the total number of Containers required for the each repeat:

• Get the total required inventory for all the repeats of all Tests. Add all the Tests in each of the repeat.

  Total Raw Quantity:

  Repeat 1 Test A, B & C	Repeat 2 Test B & C	Repeat 3 Test C
  25+10+30	10+30	30
  65 tablets	40 tablets	30 tablets

• Calculate the number of Containers needed for each repeat based on the Container size. Divide the total of 65 Tablets, 40 Tablets and 30 Tablets (for each repeat) by Container Size.

  Number of Containers Needed
  Container Size	Repeat 1 Test A, B & C	Repeat 2 Test B & C	Repeat 3 Test C

To derive the total quantity, you must define these factors that contribute to the calculation:

• Each test must execute from separate container.
• Number of individual execution/repeat required for a Test on a Sample. Repeat means how many times a particular Test would be executed for a Sample. Each additional repeat causes an additional instance of the SDIWworkItem and DataSet. Each repeat of the Test requires additional Test material.
• The quantity of material required to execute a single repeat of the Test.

  Total Raw Quantity:

  Test A	Test B	Test C
  25*1	10*2	30*3
  25 tablets	20 tablets	90 tablets

• Calculate the number of Containers needed for each Test based on the Container size. Divide the total of 25 Tablets, 20 Tablets and 90 Tablets (for each Test) by Container Size.

  Number of Containers
  Container Size	Test A	Test B	Test C
  25	1	1	4
  50	1	1	2

  200	1	1	1
  500	1	1	1

 

Calculate Quantity for Destructive/Non-Destructive Test	Top

This calculates the number of Containers needed for Tests that are Destructive or Non-Destructive in nature.

To derive the total quantity, you must define these factors that contribute to the calculation:

• Test is Non-Destructive. Non-Destructive testing does not consume material, like Test the color of the Sample. Therefore amounts are not additive (added with the total). Non Destructive amounts are treated as minimum. This kind of Test is typically performed first.
• Test is Destructive. Destructive test consumes the material during testing.
• Number of individual execution/repeat required for a Test on a Sample. Repeat means how many times a particular Test would be executed for a Sample. Each additional repeat causes an additional instance of the SDIWworkItem and DataSet. Each repeat of the Test requires additional Test material.
• The quantity of material required to execute a single repeat of the Test.
• Unit of measure associated with the Quantity.
• Whether or not the Pull Quantity is multiplied by the number of Samples. See Example.

To get the total number of Containers required for the each type of Test:

1. Get the total required inventory per Test. Add all the available Tests (also considering the number of repeats for the Tests).

   Test A - 25*1 = 25

   Test B - 10*2 = 20

   Test C - 30*3 = 90

   Total Raw Quantity = max 110 Tablets [25*1, 10*2 + 30*3]

   As the Non-Destructive Tests are performed first and it does not consumes material, the same material is used for Destructive Test later. Therefore the quantity of Non-Destructive Test (Test A - 25) is not considered for the final calculation.

2. Calculation of the number of containers needed based on the container size to get the total of 110 Tablets.

   Container Size	Number of Containers
   25	5
   50	3
   100	2
   200	1
   500	1
