Storage Design Theory

Thursday, December 31st, 2009

Whenever one considers storage options for their warehouse, it is very common to gravitate to merely looking at what options yield the most pallet positions.  Density, after all, is the goal.  Stick as much product as possible into a given space.

One common mistake that is made is to let density drive your design process.  Density is the ultimate goal, but focusing on operational efficiency is more critical.  Putting a system in that does match your operation may yield more pallet positions on paper, but in reality, can actually produce significantly less than anticipated.

“Pigeon Holing” as it is called can occur when the design does not match the operation.  This is where product cannot be stored in the manner in which it was designed.  This creates holes in the storage density and does not allow you to take advantage of all the positions you have created.

A common comparison is one that centers around two high density approaches, Pushback rack and Drive-In rack.

Pushback rack is where each pallet resides on a series of trays within each pallet location.  Every subsequent pallet that is placed in a particular location has the ability to “push” the previous pallet back one location.  This allows multiple pallets of the same SKU to be housed in a very dense fashion.  Pushback is an ideal LIFO (Last In First Out) storage layout.  It also allows for more pick facings giving you the ability to store a larger number of SKU’s in a given aisle.  The ideal application is one where you have multiple pallets of the same SKU that need to be stored and retrieved in a medium paced operation that does not require a FIFO (First In First Out) methodology, e.g. non-perishable items that do not have a short life-span.

Comparatively, Drive-In rack creates lanes down an aisle that allow a lift truck to travel into the lane to store product.  This is the densest storage media available.  However it has its limitations.  Only one SKU can be placed in a lane.  Once the lane is loaded, pallets must be pulled from the front backwards.  Once a pallet is removed, deeper pallet will not be available if you load the empty position back up.  So, to gain access to the back pallets, you have to leave the front positions open.  This reduces your ability to take advantage of the density you have created.  The ideal application for Drive-In rack is where you load a lane and flush that lane in its entirety.  Fast moving operations can benefit from this design.

The bottom line is: Don’t be driven by maximizing pallet positions at the cost of the efficiency of your operation.

You need new lighting.

Tuesday, July 21st, 2009

Without argument, if you have a facility that is currently using Metal Halide, Mercury Vapor or High Pressure Sodium, you need new lighting.  The great thing about it is that very often, these are self funding projects.  Yes, you heard me correctly.  You can put new lighting in at no cost to your company. 

Each month you get a bill from your energy company.  You have to pay this bill otherwise your power will be cut off.  Using new lighting technology will lower your lighting costs up to 75% under the right circumstances.  If you pay $10,000 a month in lighting costs and that is cut in half, the $5,000 savings will pay the lease payment.  There is no impact to your cash flow.  Once you pay off the lights, you’ll be putting that $5,000 right to the bottom line.  That is essentially increasing your net revenue by $60,000 a year.  In this economy, more revenue certainly isn’t a bad thing.

There’s more.  The federal tax credit has been extended.  That means that you can take up to $.60/sq. ft. up to the cost of the project as a credit to your taxes.  This can mean big money, lower the cost of the project and improve the payback period.

It just doesn’t make sense not to change your lighting.  Period.

Start Saving Money…Now!!

Friday, June 26th, 2009

  1. Change out your lighting – Switch from old Metal Halide or High-Pressure Sodium lamps to new T5 florescent lighting can save your company up to 50-75% in electricity costs.
  2. Install air curtains – If your facility is either heated or cooled, install air curtains on all dock doors.  This will help minimize the amount of energy you are using to heat or cool your facility.
  3. Maintain your equipment – Properly maintain your equipment will ensure that it is operating at optimal levels, minimizing the need for parts and service over the long run.
  4. Recycle –If your facility produces a lot of corrugated cardboard waste, buy or lease a compactor.  Selling bundles of waste can generate extra revenue and protect the environment.
  5. Install impact devices – Install impact devices on your lift trucks.  This will help minimize damage to the facility.  It will improve overall safety, lower replacement/damage costs and identify the culprit.
  6. Keep your floors clean – Debris is one of the leading causes of pedestrian accidents as well as damage to wheel assemblies of lift trucks.  Keep your floor clean and your trucks and people healthy.
  7. Reduce your box size variety – Lowering the number of box sizes you use.  This will give you greater purchasing power as you will buy more of a smaller range of sizes.  Use low cost dunnage to fill any voids between product and package.
  8. Evaluate every step in your process – Do not overlook even the smallest step in your distribution process.  There is a tremendous amount of technology available the can handle each part of your operation.  Take a long term view, initial capital expenditure can have a quick payback if applied correctly.
  9. Continuous Training – Turnover in our industry is generally high.  Have a structured training program to get new employees up to speed quickly and reinforce operating principles to existing employees.  There can be substantial productivity gains and reduction in damage if your employees are well trained.
  10. Make smarter purchases – Purchasing improperly specified equipment will cost you money in the long run.  Do not overlook what you are buying.  Price alone is by far the worst metric for evaluating equipment.  Whatever you are buying, you can find that product at whatever price point you have in mind.  However, be aware that spending more upfront for a more robust solution will save you money in the long run. 

Why use a Material Handling Systems Integrator?

Friday, February 27th, 2009

 

The definition of a material handling systems integrator would be a best described as a combination of both an allied products distributor and a consultant.  Where a consultant takes a fee based approach for their intellectual property and then assists in vendor selection, and an allied products provider is selling his brand against the competition, a true systems integrator provides the sales and implementation of material handling products as well as the intellectual property to properly engineer the solution. 

If a company has no in-house engineering the decision to use a systems integrator is fairly straight forward.  You are hiring an industry expert to advise and solve warehousing and distribution issues.  The decision becomes more difficult when the company has engineering resources.  Material handling projects are often over simplified, devaluing the role an integrator plays. 

Don’t underestimate the difficulty in implementing a truly integrated material handling system and diminish the value of an integrator.

A systems integrator:

·     Performs data analysis and system design

·     Validates the solution

·     Aids in vendor justification and selection

·     Procures the product at the best price

·     Installs the system; many times in a working environment (your operation never stops)

·     Commissions the system

 

Every day, an integrator is designing and implementing material handling projects.  The real issue is not so much about a company’s capability to handle these projects as much as it is about the risk associated with them.  Companies with engineering talent usually have an understanding of warehousing and distribution processes.  But even to the savviest of customers, integrators can add value by bringing a wide variety of experience to projects and uses that experience to mitigate risk.

Risks are often underestimated and can vary greatly depending on the type of project.  For instance, installing a system in a greenfield (new/empty warehouse) vs. an existing operation that needs to continue to operate during implementation are two dramatically different risk scenarios. 

Why use an Integrator?

·    Single point of responsibility

·    Performs various consulting functions

·    Is not a distributor.  Provides an independent evaluation of the most appropriate solution to a customer’s issues

·    Manages and coordinates multiple vendors and technologies for smooth installation

 

As projects become more complicated, the value of a systems integrator increases.

Don’t undervalue an integrators role.  Overruns on budget or schedule translate into escalating costs, both on the project and lost opportunity.

Protecting Your Rack

Protecting Your Rack

Rack is an expensive asset.  Even with steel prices at a low point, a rack system still represents a large percentage of your warehouse investment.  When you make that investment, you want to protect it.  Unfortunately it is common practice to overlook protection for your investment on the basis of cost.  This is a slippery slope.  Protection is inexpensive as a percentage of your total rack project.  Don’t forget that the cost to repair or replace damaged uprights and beams will quickly justify the upfront cost of protection.

What kind of protection is available?

  1. Rack guards – There are many types of guards available on the market, from individual upright protection to end of row protection.  They come in all shapes and sizes and should be tailored to the type of lift truck your operation employs.
    1. Post protector – Comes in many varieties, mostly rounded or angled to deflect impacts.  Comes in a variety of material including steel and plastic
    2. End of row – Protects the entire width of the upright, usually curved around the front of the upright at the entry point of the aisle
    3. Bollard – Multi-functional free standing post to create a protection barrier
    4. Guard rail – Is used in a number of manners.  It can be used to create a safe walk way for pedestrian traffic or to protect sensitive equipment that is exposed to potential truck damage
  2. Driver training/responsibility – Making sure that your drivers are well trained and understand that there are consequences to poor performance can be a great deterrent.
  3. Shock Switches – These are modules that are installed on your lift trucks that will disable the truck if it impacts anything.  The only way to enable a truck is to have a supervisor do so.  This will make sure that your drivers are more conscientious as the work in the warehouse.
