National Logistics Information Network

       Advanced WMS system can bring a lot of value to the logistics center, one of the most crucial and most important points is: To improve accuracy, improve operational efficiency. So why implement WMS can significantly improve the accuracy and efficiency, how to implement the WMS in order to fully maximize the return is a lot of logistics and IT managers are most concerned about. This article on how to help improve the logistics center WMS accuracy of in-depth analysis of the job.
First: managers should recognize pickers picking work in the high frequency, there will certainly be human error. Do not put the problem simply comes down to accountability. If it attributed to the sense of responsibility, which is equivalent to give up on this issue resolved. If a customer calls to ask why made a mistake, you can not sad to say: that the new warehouse and irresponsible, always a mistake, really sorry. Customer apparently will not accept this view, customers recognize the company, not the individual. Companies are obliged to take measures to address the uncertainty of individual behavior, the results to the client a definite. Of course, if someone really chaos every day, still to be processed. Otherwise it will increase the cost of correction.
       1. control of shipping errors
       once shipped the wrong things out the door and it is difficult to deal with, and will directly affect the customer experience. So we start with this link began to grasp. In fact, electricity providers do know: the review is the only way to solve the problem. Ideally review is scanned for review by piece, the first reviewer barcode scanning orders, WMS bring out all the details of the order of items displayed on the screen. Then the operator by piece barcode scanning of goods (note the piece by piece, and then enter a number instead of scanning), the system automatically deducted; if the screen all clear, and shipped complete. To avoid scanning staff distracted, scanning and scanning errors right WMS should sound.
If the number of a single product more, it can provide a number of inputs, but this will increase the probability of error. How to balance efficiency and accuracy needed warehouse supervisor decisions.
       2. How to ensure the accuracy of the review of
       I said above, review shipping accuracy can be increased to a very high standard, such as 99.9%. But how to further improve it?
       If you are Japanese: you may choose to re-arrange individual review "review." Such accuracy would increase further. After the Chinese people might choose to let him wrong, wrong, let the customer apology, sent a small gift to make things smooth. The ultimate effect is the same as the commercial (customer satisfaction),
       For certain categories of goods, it can be used to review the way the weighing assisted verification. If the carton weighing and weight have large deviation theory is prompted to re-examine reviewers.
       Analysis of this, the external problems are resolved, the rest of the errors are within the warehouse, and belongs to the "internal contradictions", although does not affect the customer experience, but will affect the efficiency of warehouse operations. Also it will indirectly affect external accuracy.
       3. Review the results of the use of
       Review found the problem solved after shipping errors, WMS capture a very important business information. If so wasted, it is very unfortunate. For example: Zhang planned to X01 location should take three apples, but the review found that he took two apples out of a pear. Then: 1. X01 location of the number of systems and the actual number may vary, and if not resolved, go after X01 apples people will make the same mistake. 2. recorded in the system put pears several locations are likely to have a problem, the problem may be caused by Zhang chaos to take, it could be chaos before, for some reason, the X01 libraries pears position. So WMS will automatically trigger a "inventory differences" action. Inventory staff see the task through RF, the first time to put the original X01 and X02 libraries bit pear inventory. The kind and number of systems to be synchronized. Avoid error propagation.
       4. How to reduce picking errors
       Then we have to analyze Zhang Why take the wrong
       a. X01 libraries position intermediate mix several pear apples
       . b Zhang is not found in the X01 location on a sufficient number of apples, then he took from the next location on what he believed to be Apple; this behavior great harm will result to take back to X02 pear colleagues chain reaction. Over time, the warehouse inventory on the whole mess.
       A problem can introduce RF, the scanner when picking location, ensure the correct position; barcode scanning of goods, to ensure that is to get things right. (This topic is actually not the end, I simply with RF, for example, will be further expanded later explained). If it is a job you can only claim Paper Zhang serious and responsible, a closer look.
B problem also needs to RF support in X01 locations Zhang got two apples later, tell the system there is no Apple, and he does not own to determine wher to find the other apples. RF will tell him to continue to take Apple X08 location. So Zhang would not take her own X02 pears of. X02's stock will not be chaos. When this happens, a good WMS waste nor will this information, but will quickly initiate a bit for the X01 libraries "inventory differences", to solve the problem Zhang found.
       It is worth noting that the system is not simple adjustments X01 location inventory based on the results Sally, but launch count, this is because the system think Sally's judgment is not necessarily correct, it should be sent in addition to the assessment of Sally's Analyzing correctness. This must be done by another person, because blind people have thought, when Zhang drain saw the corner of an apple, you let him look five times, may all look at this apple leak.
       5. How to make sorting error does not occur
       The above steps resolve the Zhang took the wrong question, but if you go to a place every time Sally stock is wrong, you need to WMS prompted several times to pick up the goods, then the efficiency is still very low.
To solve this problem which requires shelves, shift, inventory, replenishment, and so all the action will affect the stock to achieve full RF technology. WMS system to ensure accurate data and in-kind can be consistent.
On the same location through strategies to ensure as far as possible together with a SKU, do not mix. This avoids Zhang picked up scanning, no, back to a re-scan, nor waste of time. If the warehouse location is not enough, you must mix, you can configure a policy so that the appearance of large differences SKU looks put together, so pickers picking easy to distinguish.
If you have a batch delivery requirements, it is best to configure different batches not mix. Because different batches of goods appearance exactly the same (if not posted batch barcode words simply can not separately). Rather let different SKU mix, do not mix different batches.
       Use of free time constantly on the warehouse inventory cycle counting, but also a proven management to improve inventory accuracy means (we assume even using RF, still allowed the possibility of inventory will appear). Many of the policy cycle counting, not expand here.
       6. selec the sorting equipment
       Just to RF for example, there is talk about the RF device can resolve the error after picking time, but RF is not the only solution. We can pick divided into two categories: one is static chosen without feedback, such as Paper picking, or to use a download task, after good results to a computer to upload the RF chosen. Another program is the dynamic picking systems can get real-time feedback, such as online mode RF, voice picking and so on. Not real-time feedback and interaction model on the one hand when an exception occurs, the help can not dynamically obtain WMS, change plans; the other hand, over-reliance on people's sense of responsibility, to ensure that after the completion of the job to be entered into the computer correctly. It should be preferred instead of modern warehousing business. We still focuses on the real-time online interaction and feedback can dynamically program. To explore, there are three: RF picking, voice picking and sorting electronic tag.
These three programs are used to meet the requirements of customers (or already eliminated), if you want to distinguish the subtle differences, necessarily requires some extreme cases it comes to a dead end, otherwise it is impossible to distinguish. Warehouse operational requirements for general customers, can ignore the contents of this chapter.
       a. RF picking
       RF advantage is cheap, widely used in the scene; barcode scanning check and review high accuracy. The disadvantage is accounted hand, the actual picking business people need to repeatedly pick up RF, down RF, took place in the process, it might bring errors. Another drawback with Chinese characteristics: the need to know the word! ! . Oh, this is also a disadvantage, but it does some warehouse workers are illiterate.
       b. electronic tags picking
       Electronic label picking is the fastest way chosen is the most fool. The principle is: do not need to distinguish goods picking, directly take the instructions. But its limitations are evident, the first number of a chosen track each SKU is limited. Definitely not for thousands of SKU, and constantly changing electricity supplier. Secondly, the electronic tag installation and maintenance work is one of several programs in the most trouble. once the label display problems, such as 8 6/9, and so are less pricked into a chosen cause systemic error (not human carelessness, is system failure, not accidental mistake, is 100% wrong); third : As Election is not to see the goods, so the shelves accuracy becomes very critical (otherwise is 100% error rate), RF shelves still need to complete. So he's not a stand alone program.
This is what I put on the microblogging electronic tags picking on the last reason. (However, in some scenarios, PTL may be the best option)
       c. voice picking
       The basic principle of voice picking and RF is the same. Benefit is freeing his hands, to avoid picking up RF, RF down movements; illiterate can also be used on human requirements are minimal. The disadvantage is more expensive. Voice picking issues raised by users, one is that after the implementation of certain cases, less than ideal; the other said the day would be a dream all this sounds.
I think so, and implement successful or not mainly depends on the implementation of the method is correct, if the project conventional RF hardware agents implemented successful is a high probability event. If it is with a strong technical ability and professional consulting capabilities WMS vendor implementation success is a high probability event. Similarly RF project implementation, implementation PTL project was not a strong process design capabilities and technical ability, failures abound, not the voice picking specific, in any case does not describe the problem.
       The second point is a high-strength Paper if chosen the day, is also expected to cervical problems, sleep eyes are picking orders. This issue needs to rationalize warehouse rest; and improving efficiency is a necessary condition can break out of time.
       d. from the money of the retail industry norm, to talk about the advantages of voice picking of humanity
       We have not noticed, when we buy something, when to eat no matter what size store, the money people will "sing sing receive pay." If there is any type of work than picking more "repetition, monotonous" error problem is more serious, it is the retail money, find the money work. Repeat once a long time people do something, it will be in a state of numbness gradually, thought would go to God. Guests will be received a 50 yuan, 100 yuan but not carried out carefully in accordance with the change; or the customer that I like to give you time to 100 yuan (client himself get distracted), can not remember in the end received 100 or 50 situation.
       To avoid this problem, the retail industry invented sing sing pay income model. Charge you 50 to find your 32.80. Benefit is to remind customers 1. I received is 50, not 100. The more important is to remind ourselves once received 50. The dispute is before the remark will emerge more clearly in the mind out; sing pay 32.80 32.80 also remind myself to find, do not go to get the wrong God. Sing Sing pay income by the amount of cold clear instructions into a brain, so the brain from numb state, short, quick access to clear state.
       Tips such as WMS picking three. RF who looked instructions, generally not in accordance with the provisions to take a sweeping one. It is likely to sweep three times in a row, put down the gun, and then get the results to go God only took two. Voice picking hear take three, because there is no gun, firing interference, often take more accurate; when he may also take away God, only took two. At this point, he replied system: three (his Teng awakened, realized that he take less), or answering system: 2, the system prompts something less. The effect on income and retail industries sing sing pay is the same.
Therefore, from the principle of speaking, voice picking accuracy than RF. However, considering the last part of security have reviewed this subtle differences so it is not so high. Who, in turn, high efficiency is the key point of the decision. If no review (the electricity supplier is no outside review of many industries), the difference is obvious.
       7. Finally back to people
       Front said to tolerate workers make mistakes, certainly according to the premise of the design process will make mistakes. But who really is the most important. If someone really has been negligent, (if occasionally mistakes are not corrected in time, almost all of them will become a malpractice) no matter how good the process is not running.
WMS should be able to provide good quality statistics and traceability, every single if an error occurs, can be traced to elect officers, review staff or team, and be able to report statistics; managers establish incentive system is based on data provided by WMS, people's problems can be solved. Mistake, the primary responsibility should fall on those who review every wrong sum should be punished. For the elect, within a certain error rate is acceptable, better than the average error rate of employee reward, punishment is far below the average error rate of employees.
