Most of the inbounds putaway location is TEMP or FLOORS. This indicates a detrimental issue of overloading, whereby the warehouses ran out of space to store the goods. There can be another possibility, where the storehouse is not properly utilized, and thus temporary and floor areas are used predominantly.

As a warehouse, quantity of products might not be as prevalent a contributing factor as compared to the number of pallets. The warehouse itself contains shelving location for such pallets to be stored in. Each shelf is able to store 1-3 pallets. However, as seen from the distribution analysis, the number of pallets vary from 1 to a whopping 669 pallets (Overloads the whole warehouse). Although these scenarios are not common, it only takes one inbound of 669 pallets to cause a problem of overloading. This is similar to a dog-food distribution, with a heavy positive skew. Based on the right skew, the mean value will be greater than the median value, thus the median would be a better choice for estimation in this scenario.

This graph shows the number of pallets received by date. From this graph, we can deduce that in general, there is a consistent inflow of B.Braun products regardless of dates. However, there are outliers as shown by the representation of 669 pallets.

This diagram shows the average number of pallets coming in to the warehouse by month. As shown from the graph, there is generally two peak periods of inbounds, Q2 – April to June, and Q4, the end year period. This information would be useful for warehouse managers to have a brief insight on storage preparation to ensure less temp and floor location usages.

This graph further slices the time dimension to a weekly level analysis. In this graph, we can see generally in each week, there is at least 1 pallet coming in on average. Week 25 and week 51 are the outliers, with both of these weeks reaching an average of 5 to 6 pallets inbound. The rest of the weeks generally fall between 1 to 4 pallets inbound a week on average. In this graph, we decided to use the bar chart because our group feels the bar graph has a better visibility for 52 weeks compared to the line graph. As such, for months we will display using the line graph while for weeks, bar graphs will be used.

In this graph, we continue from the other diagram where we compare the relationship between number of pallets to the time dimension, month. In the previous graph, we look at all pallets, however, each inbound may be a small or large inbound, with regards to the number of pallets per transaction. Thus, our group decided to group all inbound transactions that involve one or less pallets to be a small inbound. Anything more than 1 pallet per inbound is considered a large inbound. The graph shows the average of small inbounds, with 1 being a 100% of inbounds being small and 0 being 0%. From the graph, we can see the lowest percentage of small inbounds is 88.5%, which shows us that a vast majority of B.Braun inbounds are small – one or less pallets. This portrays the problem of maximizing warehouse utilization, as if inbounds are of high frequency, allocation might be difficult and time-consuming.

The complication of big data resonates strongly with the company, much like many others. The Warehouse Management System (WMS) captures data of logistics supplies in the warehouses of the company, such as quantity of movement, time of movement and identification codes of the packages stored. With extensive data provided by the WMS, analyzing of spreadsheets can be cumbersome and inefficient due to visualization impediments. The company is unable to effectively analyze and sculpt solutions as a result. <br/>

In addition, the company is in the midst of implementing a vertical lift high-tech system  for its new warehouses in its upcoming Supply Chain City (SCC) project. In light of these recent developments, the company saw an opportunity to better analyze their WMS data to determine its Stock Keeping Unit (SKU)’s inbound rate, outbound rate, warehouse utilization trend, and ideally, by performing the aforementioned analysis, categorizing each SKUs into namely A, B, C categories. ‘A’ category refers to fast moving SKUs while ‘C’ category SKUs refers to slow moving SKUs. <br/>

Moving on to the large inbounds, we notice the vice-versa of trends as compared to the small inbounds. Large inbounds do not take up more than 11.5% of the inbounds per month. However, these inbounds can go as high as 500+ pallets, which is much harder to control and maintain as compared to small inbounds. Ideally, the large inbounds should be kept as low as possible as too many of these large inbounds can lead to overloading of the warehouses.

<br/><br/><br/><br/><br/><br/><br/><br/><br/>
  
With the analyzed results, the company hopes to determine the optimal warehouse location and vertical lift in which a particular SKU can be placed for picking. In addition, the company would also like to see the extent of productivity savings it can obtain with the adoption of a batch picking technique instead of an order picking technique. Order picking involves going into the warehouse to collect the supplies per order basis, while batch picking involves collecting for multiple orders in a batch.<br/>

Similar to before, we slice the time dimension to weeks, to see whether the same consistency is valid for the weekly basis. As compared to the small inbounds, there is much less consistency when it comes to large inbounds. Variations range from close to 0 to almost a quarter of the inbounds for a given week. This makes it harder for the warehouses to prepare for large inbounds. In week 38, the percentage of large inbounds went to 23%, an outlier compared to the other weeks. The usual range of inbounds varies from 1% to 16%. From this graph, it is safe to say at least 1% of the inbounds would be large inbounds.

There are 3 main locations, 224, 407, and 9800000074. For the x-axis, if the number of pallets incoming is less than or equals to 1, the pallet inbound would be “Small”, if not “Large”. From all 3 locations, the number of pallets that inbounds with 1 or less pallets takes majority of the inbounds. Particularly, shipped from location 9800000074 is the most popular.

Putaway Location Analysis


Skulptors-PutawayLocation.png




Most of the inbounds putaway location is TEMP or FLOORS. This indicates a detrimental issue of overloading, whereby the warehouses ran out of space to store the goods. There can be another possibility, where the storehouse is not properly utilized, and thus temporary and floor areas are used predominantly.

The warehouse itself contains shelving location for such pallets to be stored in. Each shelf is able to store 1-3 pallets. However, as seen from the distribution analysis, the number of pallets vary from 1 to a whopping 669 pallets (Overloads the whole warehouse). Although these scenarios are not common, it only takes one inbound of 669 pallets to cause a problem of overloading. This is similar to a dog-food distribution, with a heavy positive skew. Based on the right skew, the mean value will be greater than the median value, thus the median would be a better choice for estimation in this scenario.

This graph shows the number of pallets received by date. From this graph, we can deduce that in general, there is a consistent inflow of B.Braun products regardless of dates. However, there are outliers as shown by the representation of 669 pallets.










Mean (Number of Pallet) by Month Analysis

As shown from the graph, there is generally two peak periods of inbounds, Q2 – April to June, and Q4, the end year period. This information would be useful for warehouse managers to have a brief insight on storage preparation to ensure less temp and floor location usages.

Week 25 and week 51 are the outliers, with both of these weeks reaching an average of 5 to 6 pallets inbound. The rest of the weeks generally fall between 1 to 4 pallets inbound a week on average. In this graph, we decided to use the bar chart because our group feels the bar graph has a better visibility for 52 weeks compared to the line graph. As such, for months we will display using the line graph while for weeks, bar graphs will be used.

In this graph, we continue from the other diagram where we compare the relationship between number of pallets to the time dimension, month. In the previous graph, we look at all pallets, however, each inbound may be a small or large inbound, with regards to the number of pallets per transaction. Thus, our group decided to group all inbound transactions that involve one or less pallets to be a small inbound. Anything more than 1 pallet per inbound is considered a large inbound. The graph shows the average of small inbounds, with 1 being a 100% of inbounds being small and 0 being 0%. From the graph, we can see the lowest percentage of small inbounds is 88.5%, which shows us that a vast majority of B.Braun inbounds are small – one or less pallets.
