It automatically calculates the necessary width, length, and height of the automated warehouse based on bucket size, storage capacity, and layout conditions.

🗂️ Supported Bucket Sizes

4 Standard Bucket Types

Custom Dimension Mode

📐 Calculation Parameter Details

1. Bucket Dimensions

2. Storage Capacity (Layout Configuration)

3. Width Dimensions

4. Length Dimensions

5. Height Dimensions

🔍 Main Methods Details

1. Form Load Processing

Initialization Process:

1. Display copyright and validity period
2. Get the path of the program startup folder
   MyJpgPath = Application.StartupPath() & "\Jpg"
3. Clear the custom dimension message label
4. Execute bucket AS/RS calculation (initial display)

2. Bucket Type Selection Processing

Processing Details:

• When a standard type is selected (BK31, BK40, BK51, BK60):
  • Set each TextBox to read-only (ReadOnly = True)
  • Change background color to Snow (White)
  • Automatically set dimensions according to the selected type
  • Clear the custom dimension message
• When Custom Dimension is selected:
  • Set each TextBox to editable (ReadOnly = False)
  • Change background color to Bisque (Beige)
  • Display message: "Execute recalculation after entering each dimension."

3. Bucket Dimension Check

Verification Details:

4. Bucket AS/RS Calculation

Calculation Flow:

1. Execute Dimension Check
   BucketDimensionCheck()
2. Get Bucket Dimensions
   BK_W = CDbl(BK_WTb.Text)
   BK_D = CDbl(BK_DTb.Text)
   BK_H = CDbl(BK_HTb.Text)
3. Calculate Storage Capacity
   Stored Bucket Count = Units × Columns × Bays × Tiers
4. Calculate Width Direction
   Rack Depth = BK_W + 25
   Total Rack Width = Rack Depth × 2 + Crane Aisle
   
   If Units = 1 Then
   Required Width = Total Rack Width + Adjacent Clearance × 2
   Else
   Required Width = Total Rack Width × Units + Adjacent Clearance × 2 + Inter-Rack Clearance × (Units - 1)
   End If
5. Calculate Length Direction
   Effective Rack Width = Rack Width Clearance + BK_D + Rack Width Clearance
   Bay Pitch = Effective Rack Width + Rack Width Clearance
   Total Bay Pitch = Bay Pitch × Bays
   
   Required Length = Total Bay Pitch + Pillar Width + I/O Conveyor + Work Area + Protective Fence + Inspection Aisle
6. Calculate Area
   Required Area = (Required Width × Required Length) / 1000² [m²]
7. Calculate Height Direction
   1st Tier Height = Deck 1 + Insertion Height Clearance
   Standard Tier Height = BK_H + Insertion Height Clearance
   Reinforced Tier Height = Insertion Height Clearance + Reinforcement Height + Lift Clearance + BK_H
   Top Tier Height = Lift Clearance + Deck 2 + BK_H
   
   Standard Tiers = Tiers - (Top Tier Count + 1st Tier Count + Reinforced Tier Count)
   
   Required Height = Total 1st Tier Height + Total Standard Tier Height + Total Reinforced Tier Height + Total Top Tier Height + Ceiling Clearance

5. Recalculation Processing

Processing Details:

• Visual Feedback (Toggle GroupBox background color):
  • Initial: LightYellow
  • Recalculation: Honeydew → LightYellow → ... (Alternates)

⚠️ Important Notes and Constraints

Calculation Prerequisites

Practical Notes

Validity Range for Input Values

Using the Calculation Results

• The calculation results are theoretical. Consider safety factors in actual design.
• Final specifications must be determined through discussion with equipment manufacturers.
• Designs with allowances for future expansion are recommended.
• Compare multiple plans and select the optimal solution.

🎓 Basics of AS/RS Design

Selecting the Number of Units

• 1 Unit (Single-sided): Small scale, reduced initial investment, ensures expandability.
• 2 Units (Double-sided): High-density storage, improved crane operational efficiency.

Determining Bays and Tiers

• Bays (Depth): Building length constraints, securing storage capacity.
• Tiers (Height): Ceiling height constraints, crane capabilities, retrieval times.

Guidelines for Crane Aisle Width

• Small Buckets (up to BK40): 1,000 - 1,200 mm
• Medium Buckets (BK51-60): 1,200 - 1,500 mm
• Large Buckets (BK60 and larger): 1,500 mm and up

Placement of Reinforcements

• Structural reinforcement is typically needed every 5 to 8 tiers.
• Structural design must account for seismic and wind loads.
• The spacing between reinforcements becomes narrower for taller structures.
