Warehouse cargo planning and adjustment of operating efficiency is the most effective way to improve
As we all know, to achieve effective supply chain logistics and distribution is one of the decisive factors in competitive advantage. Whenever and wherever, manufacturers could only choose the most efficient logistics and distribution methods in order to improve customer service levels, in order to establish a competitive advantage.
Statistical data warehousing community, traditional warehouse staff in the library of pure walking time, more than 60% of the total working time. For the above, according to the mobility of goods was reasonable distribution of cargo space, can significantly improve operational efficiency. Practical experience, we have found: cargo warehouse planning is to determine the productivity of important design considerations. With a small amount of investment, re-planning, adjusted warehouse cargo space, can improve operational efficiency, enhance customer service levels of business objectives.
And logistics managers on how to properly plan warehouse cargo space, and from the engineering point of view, discusses the planning step by step method of operation. Through the implementation of the methodology to provide our logistics warehouse manager can grasp the cargo space planning approach, under the premise of minimum investment, make full use of existing storage resources, reduce warehouse operating costs, improve user satisfaction.
1. What is the cargo space planning?
Currently, the traditional warehouse material handling operations, 40% of the unloading, storage, picking and loading operations of the total operating time; the remaining 60% of the operating time, the walk takes workers. Taking into account the cost of labor costs in the proportion of traditional warehouse reaches 40 to 50% or more, this set of numbers is more worthy of our attention.
In the traditional warehouse, warehouse labor costs 40-50% of the total cost. If so? More than 30% of the cost of the warehouse, actually spent on the way to and fro? Many logistics managers in this group of figures surprised. From another angle, you were the last time the library material goods flow analysis and cargo adjust what time? If you forget, then it is likely that you already belong to a warehouse inefficiencies we previously mentioned "traditional warehouse" category .
Because most of the time consumed in the library workers to walk, so from the perspective of resource utilization efficiency and improve logistics, reduce warehouse operating costs can walk to shorten the distance from the start. Rational planning of goods cargo space is the best way to achieve this goal. The main objective of cargo space planning is: when dealing with any SKU goods, minimize, or even eliminate travel time.
1.1 rational planning cargo What are the benefits?
Definition of cargo space planning is "the goods included in the reasonable storage facilities, in order to achieve optimal material handling and improve space utilization goals."
For example, the high turnover of goods distribution near the cargo receiving area can improve the speed of warehouse storage. However, warehouse storage is just a one-time job, if the operator needs to be repeated replenishment or picking the goods, then, the distribution of the goods in shipping dock or picking area near the cargo space is more favorable. Planning and adjustment of goods cargo logistics is an effective means of keeping always in perfect running condition. However, because many warehouse manager did not have to fully understand the significance of this work, ignoring the regular cargo planning and adjustment until someone complained that not enough warehouse, find the channel filled with goods, we realized that a serious problem.
By cargo planning and adjustment, you can achieve the following results:
Place the goods in accordance with reasonable picking order picking personnel can reduce the number of the corresponding cargo specifications, assign the corresponding number of units of goods, can reduce the number of personnel replenishment balance operator workload, can reduce cycle times and improve workflow.
The confusing items assigned to different picking zones can improve picking accuracy ergonomically optimal placement of goods planning theory, to avoid injury on the job picking path, the weight of the goods at the front end planning, afraid to bump the rear end of the wine, you can reduce product damage.
Distribution of goods in accordance with the height of the cargo space, realize goods tiered closely stacked, stacked pallets can improve efficiency, improve efficiency in picking the wagons
By adjusting the warehouse layout, improve space utilization, you can delay or avoid the build investment
Hair Category laying, can reduce the workload of secondary sorting client logistics center, improving the overall efficiency of the supply chain
The importance of 1.2. Cargo planning and adjustment
Put into use early in the warehouse, cargo should begin planning and adjustment. The reason is that, regardless of the initial cargo plan how perfect, ultimately changing business environment will lead to the current plan is no longer applicable. In the warehouse daily operations, operational matters Change in the pattern of the existing display of goods have occurred, but also on fire safety requirements, day after day, cargo rational allocation and adjustment was gradually forgotten, this is the number of logistics centers reason enough to always use the warehouse. At a time then re-planning of cargo space, which is often difficult adjustment. Cargo adjust daily work and should be avoided when the accumulated problems to tackle piles, frequent adjustments to avoid cargo into the aforementioned dilemma.
Whether it is working to build a new warehouse, or to find ways to improve the existing cargo warehouse layout, display of goods and reasonable methods are not only save investment, but also an ideal place effective means to improve warehouse efficiency. Through database software or spreadsheet application, we can in a few days to complete a cargo warehouse planning adjustments. Integrated with WMS cargo space planning and design, daily cargo adjust the software has also been developed, compared to the potential benefits it brings, the purchase of such investment is only a fraction of the software.
2. cargo planning and adjustment, where to start?
To be effective, before adjusting cargo space, there are several preparations need step by step. Comprising: selecting a cargo planning strategy, a clear target cargo space planning, data collection and cargo space planning needs analysis. Not ready to stage a thorough analysis, it is impossible to achieve the desired effect of the adjustment.
2.1 clear objectives
Whether the face of any goods and cargo space planning project, clear objectives is the first job content. Clear objectives detour to avoid the follow-up and repeated, goals are not clear, it is likely to work when half found the wrong direction.
Target two aspects - effectiveness targets and limiting factors. The effect of the target is usually the operating efficiency of cargo space adjusted to improve the definition of indicators. Improved efficiency indicators usually include shortening the distance traveled, reducing replenishment workload balancing operator workload and improve picking efficiency. Limiting factor refers to cargo planning and adjustment issues that must be considered, generally satisfy these limiting factors to the loss at the expense of the efficiency of warehouse operations. These factors include the weight of cargo goods, cargo size, picking accuracy and operational efficiency of the safeguards requirements of the logistics center and other end users.
The effect of the target is usually the operating efficiency of cargo space adjusted to improve the definition of indicators.
Once clear of the above objectives, it should be prioritizing. For example, the most basic principles of planning and adjustment of cargo is to determine the distance and location of the goods cargo receiving area / dispatch area in accordance with the material flow of goods. Generally, however, this is not the highest priority consideration. Because, despite the above method can reduce the distance traveled picking, but there are many other factors should also be taken into account. If you do not consider, such as cargo capacity, the weight of the goods, the goods classification storage requirements and size and other factors, although by reducing the distance traveled can win considerable work efficiency, but also may bring the transfer path blocked, damaged goods, replenishment and large jobs poor security consequences.
Therefore, when considering that the warehouse community a target factor should take into account the impact on other warehouse operations. For example, office equipment distribution logistics center, we must fully consider the stacking order of goods. Compared with other targeted factors, to prevent breakage of goods should be the highest goal of such logistics center. In picking the goods to heavy, not afraid of bump goods, such as seat cushions (although turnover of the goods may not be high), the underlying code on the pallet; then a layer of paper or may consider other merchandise FCL ; easily damaged goods, such as stationery holder, calculators, you should pick the code on the top of the pallet (although these goods were high mobility). Accordingly, the order picking area cargo space planning should follow the above requirements to determine the sequence of goods, reasonable stacking guaranteed product quality. When a different angle, in the category of easily damaged goods, make the cargo plan should also take into account the respective turnover rate to select the appropriate cargo.
2.2. Data collection
After clear planning objectives, selecting and analyzing data collection plan is the second job. Planning objectives determines what data should be collected. Data should include information on the characteristics of cargo space, demand for goods and product information files.
The following is the data analysis may be used for some basic data: cargo identifiable information, cargo types (such as storage cargo or picking bits), storage device types (such as trays, Rack Corridor, flat stacking mode, etc.) , picking the type of device (such as a power pallet flow racks, carton flow force cargo, cargo space depth and cargo carrying capacity.
From WMS or ERP, can be downloaded directly order or delivery order information file acquiring goods. Generally, in order to find out the needs of the seasonal variation of goods, SKU long-term growth / change-out feature and other logistics information, the time span of such a document should be in a few months, so that more than one year. Above information also select an entire disk, FCL or unbundled picking strategy important basis.
The following is the product characteristic information and data analysis may be used: identity information of goods, goods category, the proportion of shipments line item, SKU, item height, item width, depth goods, goods weight, goods demand growth, unit of measure, the packaging / pACKING, quantity / pallet goods development plan, the average reserves.
2.3 Requirements Analysis
After data collection, the third task is the logistics needs of content analysis. Needs analysis is to determine the purpose of picking and replenishment attributes for each product. The first step in needs analysis is the number of shipments for each product and method of picking analysis. Analysis method, the line item for each order picking decomposition of the entire disk, FCL picking, and picking unbundled category. Furthermore, all the SKU performed ABC classification, A class of goods turnover the highest category C goods turnover to a minimum. Typically, A class of goods accounted for only 10 ~ 20% SKU goods distribution, and it is precisely this small part of the specification of goods account for the total number of line items shipped from 70 to 90%.
The next job is to define the different goods picking the right equipment. First, the data analysis data mentioned above is calculated for each unit of the replenishment quantity of goods to determine the goods turnover. The turnover rate is the selection picking device basis. If a replenishment of goods need two units per day, which should be large cargo space than a day requires a replenishment unit of goods cargo space. Then again, we need to count the number of each item by order determine the goods' dynamic touch number. " Day of goods / weekly / monthly subscription frequency that is decided based on the specific location of your choice picking - goods with a higher "dynamic collision frequency" should correspond to the most suitable for high frequency Picking cargo.
3. The cargo space planning strategy
Upon completion of the planning needs analysis, specific goods layout work can begin. Have multiple functional areas of picking and a variety of equipment integrated logistics system, cargo space arrangement can work in two steps: First, the definition of the respective goods partition, then after each product planning to the specific cargo. Specific cargo space is arranged to follow the above "OK planning objectives" principle.
