Circumstances that Change the Battle Ground

An appropriate improvement programs and structured implementation plan for distribution center advancing to reduces timeframe and promotes the success of programs.

Implementation programs, probably can be invasive, disruptive, and even counter-productive, causing considerable expense, possibilities of wrenching business-process change, and gnawing uncertainty in the minds of employees. Yet surveys show midsize businesses are increasing investment in state of the art of technology for enterprise level system such ERP, WMS, TMS and others to stay competitive, tapped the benefits of integrated data, streamlined processes, managed inventory and other benefits promised. Unfortunately, there is no magic pill guarantees any implementation will be quickly, painless, and successful.

attackA big automotive parts company, which is one of our clients, has already been successful executed improvement programs and create values without risk of catastrophic failure.

Tempting to rebuild a new distribution center blueprint in terms of both capacity and capability, the new design was cost effectively accommodate future growth and advances in technology. It take into account of foresight and forward thinking to successfully converge equipment, software, people and processes in an expanded “house.” Flexibility and scalability become integral design factors to achieve the perfect balance between initial investment and future expandability.

Related to distribution center design and operation, the algorithms alone are insufficient in determining an optimal solution. Without an objective blueprint for design, it can fall into the trap of designing around the promise of a material handling equipment brand rather than blending the ideal equipment, WMS, WCS and associated technologies according to the specific demands of each company’s unique distribution model.

The four smart programs in a new distribution center blueprints:

four-pillars

# 1  Reduce movement to optimize task efficiency.

“Movement” is considered one of the seven (or eight, depending on who’s counting) wastes of lean manufacturing. According to Paul A. Myerson, Professor of Practice in Supply Chain Management at Lehigh University, waste of movement “occurs when temporarily locating, filing, stocking, stacking, or moving materials, people, tools, or information.”

Unnecessary or excess movement can be the result of a combination of factors, ranging from poorly lay out to placing stocks, pass over product velocity and too long inbound travelling path, to inefficient working methods.

To reduce movement, they need to increase operator efficiency, such as with scheduling system. In its simplest form, Wave Planning is considered a “scheduling system for replenishment & picking operation.”  Wave planning builds upon that principle by setting time windows of the replenishment of stocks and or picking operations on the shop floor at the moment that it’s needed. The result is a timely, even flow of goods and worker assignment that eliminates bottlenecks and interruptions.

To further eliminate excess movement, consider locating inventory stocks closer to the pickers access and strategically positioning stock at velocity based locations to maximize the efficient flow of products.

# 2  Improve supply chain scheduling to reduce bottlenecks.

Things don’t always go as planned. Replenishment & fulfillment flow can be greatly impacted by the availability of stocks or by disruptions, such as late receipts of incoming stock, equipment breakdowns, quality rejects, and other issues during inbound process.

With early detection capabilities and real-time access to storage capacity, availability, and interdependencies of resources needed, system, and data, through Advanced Notification System (ASN), however, they have access earlier to the information needed to adjust schedules to accommodate those disruptions. With the right systems in place, they can even determine if change requests are feasible, estimate the impact of those changes on every aspect of end to end warehouse processes, and minimize potential impact on operation.

For the best result, they should avoid making unplanned changes during procurement vis-a-vis inbound operation, and instead attack supply demand problems directly. The scheduling system allows them to model what-if scenarios, their warehouse man can simulate the alternatives so they can choose the best approach.

# 3  Optimize inventory levels to reduce shortages

The distribution center shop floor can’t be productive if don’t have the materials needed for their fulfillment. When they suffer from inventory shortages (whether it’s a result of late deliveries, unexpectedly high reject rates, or short counts), the proper response is not to increase safety stock levels. Not only does this reduce cash flow and increase inventory carrying costs, but their data has shown that increasing safety stock levels isn’t even a sure guarantee against inventory shortages.

Instead, having accurate and timely visibility into their inventory allows them to know exactly what items are running low in stock, detect potential issues, and rectify them before they become real problems. Also, establishing close working relationships with their suppliers can help speed up fulfillment requests. They prioritized some suppliers connect to their system via Electronic Data Interchange (EDI) as well as Web Services. When inventory will run out, then the system trigger automatically to order to supplier for replenishing them.

Sometimes inventory shortages can’t be avoided. In those cases, by the right planning system, they can earlier identify the impact of the shortages and determine how best to redeploy resources in the interim. It’s also a smart idea for them use contingencies built into the plan—such as alternate suppliers and substitute parts—that could be activated on short notice.

# 4  Automate processes with automated data collection

One way to speed up shop floor operations is by automating their shop floor processes with automated data collection tools, like barcoding. With barcoding plus android based mobile devices, key inventory and asset data (such as quantity and location) can be automatically captured and drive the flow of inventory and shop floor assets (such as totes, bins, racks, and pallets). Barcoding and Android based Mobile Devices help speed up data collection and improve data accuracy by bypassing slow and error-prone manual data entry.

Barcoding technologies, can also help reduce processing time of data reading. With barcoding technologies in place, they can automate the gathering and sending of asset information (such as location, product code readings, and storage bin status) without requiring an operator to have direct line of sight or contact with that piece of them. In our proposed plan, the types of information that RFID can gather help them increase capability for identifying patterns by implementing it in the future.

real-time-info

Through complete visibility into every step of shop floor operations, they have access to the information needed to make the most effective usage of constrained resources, find areas where they can increase throughput and efficiency, and promote better material, asset and even their people. Being able to see how all of the pieces fit together—in real time—ultimately helps them operate more efficiently and make better decisions. Onwards, they can identify potential problems earlier, analyze them, discover what’s driving them, and identify solutions before they create bottlenecks.

Light or Voice, which one is the best choice for your warehouse ?

AT707-4K-RFID.jpgLight technology were gaining wider acceptance for last 15 years ago. In the early emerging period, light technology has been adopted throughout warehouse 20,000 modules which the only Fortune 100 companies could affordable for. By the time, in the last couple years, light technology improved drastically their hardware become as few as 300 modules. The differences make light technology have more accessible for smaller companies.The main reason, retailers or companies interested in, because light technology suitable with or possible to use within a less than case quantity picking operation in their distribution center.

In warehouse, order picking is the most expensive and labor intensive operation. Many retailers have the reason to pay attention more in this area. But nowadays, trend in material handling technology, we could find voice technology as an alternative. Voice technology is a very good technology even come with less speed in interaction and language barriers since user has to listen and talk back and forth as Ken Ruehrdanz, Warehouse and Distribution Market Manager at Dematic. Voice technology claimed one of the best choice for retail because this technology has competitive advantages in a reasonably low investment rather than light technology. Voice technology, recently predicted has significantly growth in sales. Voice technology claimed as supplant light technology which come first in the market.

Recently,both light and voice technology become demanding technology which have possibility for further adoption in broader retail supply chain. In the real operation environment, both of them actually have limitation, they are limited by certain circumstances.

Lights or Voice, which one is the best for you ?

Even voice technology claimed as the best choice in improves productivity and accuracy with a reasonably low investment, light technology claimed has same level degree of accuracy but more in productivity. It’s sound like balance. In fact, voice and light technology are each “best” only in certain circumstances. It is relatively easy to identify in which circumstances :

(a) voice requires less investment than lights and improves productivity to almost the same degree,

(b) lights require less investment than voice and increase productivity to a much higher degree and

(c) a hybrid of voice and lights, driven from a common software application, provide the best blend of investment and productivity improvements.

 Voice and Light

Referring on how Voice and Light works, above figure, we found that some parameters i.e accuracy, productivity and investment are in the same level for both. For detail analysis, we should define “certain circumstances” as a factor which influence them in operation. Let’s look at warehouse process, order fulfillment process where the voice and light technology will be used, assume, mainly we have 2 categories of SKUs, there are Fast Movers an the rest are Slow Movers. When there are a large number of rarely picked from (or put to) location, it’s mean Low Reach Density environments because of few reaches per unit of travel occurs. Inversely, when there are a small number of frequently picked from (or put to) locations, it’s mean High Reach Density environment because of many reaches per unit of travel occurs.
The question is why travel time so significant consider in this case ? The answer is because travel time between reaches affects productivity, reach density impacts the amount of labor required to fulfill orders. If we assuming volumes are constant, the reach per hour,  so rate of an order filling will determine the number of operators required to fulfill orders. In our conclusion, we stated that  Reach Density is key  in determining whether lights or voice is the more appropriate technology.

matrix voice and light

Multi – modal use on the rise.

What about using the two of them together? In fact, we have possibility to applied them simultaneously in the same facility. We have scenario to set  lights for the fast-moving, split-case items and the opposite side, voice for everything else. We expect to take benefits from light as a visual system, it will deliver more efficient, more productive picking while voice, due to less in investment, we expect in wide coverage of location can be applied or covered. As demonstrated by the scenario, a hybrid of light and voice would require much less investment than an all-voice or an all-lights solution. At the same time, combination of them would provide nearly the same productivity as all-lights and much higher productivity than all-voice. The hybrid model, therefore, provides the preferred blend of low investment cost and high productivity.

What you should do before decide whether Light or Voice Technology that fit to your warehouse operation ? Here are some tips.

1. Determine Reach Density – High, Low, Mixed ?
       Low reach density operation :
              Voice is similarly as productive as Light
              Voice requires significantly Less Investment
       High reach density operation :
              Voice is significantly less productive than lights
              Voice requires significantly more investment
2. Take advantages of the analytic tools available
3. Stay to speak with objective vendor (not just voice or light)

6 Phenomena that Your Warehouse Operation Need to Move to A New System

ASRS

Do you feel your warehouse operation no longer competitive ? This is the right time for you to evaluate your warehouse operation. Before you decide anything for your warehouse operation, please consider some important tips below. Below are the 6 important tips will help you to guide whether you are in the right time to move to a new system.

1. Keep pace with industry trends in your challenging market
The availability of new technologies and increased market demands are driving rapid change in many industries. Industry trends signals such as rising customer expectations, increased competitive pressure, or dropping margins will drive to create a new standard industry. Introducing new or improved automation management technology to your warehouse can be a powerful tool for increasing competitiveness in a challenging market.

2. Ensure compliance with EDI requirements.
If you plan to sell to large retailers, you’ll need to comply with their terms in order to remain in good standing and keep your margins in place. Most large retailers have strict vendor compliance requirements that make a modern warehouse management system absolutely critical for success. Since many large retailers use EDI (Electronic Data Interchange), an ideal WMS solution will have EDI integration and be able to automatically transmit order information into an ERP (Enterprise Resource Planning) system

3. Manage the changes required by e-commerce
If you’re one of the many businesses selling products over the Web, a WMS is essential. An online business encounters higher transaction volumes and greater customer expectations. Your material-handling needs also change when you ship directly to consumers rather than to businesses. Instead of pallet or case shipments, most online businesses fulfill many small unit shipments. As shipping times decrease, new requirements such as cross-docking may be required. Without the right system, many errors can occur. And with thin margins, shipping errors can be detrimental to your business. You want a WMS solution that supports and integrates with your e-business initiatives.

4. Automating your warehouse
If you’re finding that the lag time between warehouse activities and the entry into your
warehouse system or accounting database is slowing down your business, you may want to consider automating those processes. A strong WMS solution integrated into your ERP system will allow you to monitor the warehouse activities in real time, minimizing entry errors, and measure the efficiency of your warehouse employees.

5. Make the most out of a warehouse move
If you plan to relocate to a new warehouse, this may be a good starting point to implement a new warehouse management system. By designing a plan from the ground up at your new location, you can eliminate the bottlenecks and inefficiencies of your old warehouse. The sooner you plan and implement, the sooner you can reap the benefits of your new system.

6. Measure your current capabilities
An objective way to assess your warehouse efficiency is to conduct a detailed benchmark measuring your current capabilities. The benchmarks can show you how well your warehouse is performing and the areas you may want to improve. If your assessment indicates significant changes are necessary, now is as good a time as any to implement a new system that provides the required functions of your warehouse.
