Analysis of FIFO, LIFO and Random Picking Scenarios Suitable for Using Warehouse Racking

Warehouse Shelving Selection An Analysis of the Applicability of First-In-First-Out FIFO, Last-In-First-Out LIFO, and Random Withdrawal

With the increasing importance of modern logistics and supply chain management, the selection of warehouse shelving has become an indispensable issue. We usually face three main types of outbound modes First-In-First-Out FIFO, Last-In-First-Out LIFO, and random withdrawal. Each mode requires different storage strategies and shelving types. Next, we will analyze the optimal shelving choices for these three modes.

First-In-First-Out FIFO

In the case of First-In-First-Out, the design of the shelves should ensure that the goods that were stored first are retrieved first. This model is common in consumer goods industries such as retail and food and beverage, where inventory turnover rate is a key operational indicator. To improve turnover, we need to ensure that goods are arranged according to their order of entry when stored, so as to facilitate quick and efficient retrieval. We recommend using dense storage shelves, such as shuttle racks, automatedwarehouses, or gravity racks. These shelves can precisely control the position of goods, enabling accurate picking and thus improving efficiency.

Last-In-First-Out LIFO

In the case of Last-In-First-Out, we need to prioritize the physical properties of the goods, such as weight or volume. In this situation, the shelves must be able to withstand heavy loads and allow us to select goods without relying on manual intervention. We recommend using gravity racks, mobile racks, or cantilever racks. These shelves typically have automated selection functions that can sort goods based on their physical properties, thereby achieving the Last-In-First-Out mode.

Random Withdrawal

In the case of random withdrawal, we do not care about the sequence of the goods, but only focus on ensuring the efficiency of the withdrawal process. In this situation, we usually choose open storage shelves, such as beam racks or board racks. These shelves are designed simply and flexibly, and can be adjusted according to actual needs. At the same time, they are also more suitable for manual or semi-automated warehouse environments.

However, it is worth noting that each type of shelf has its own advantages and disadvantages, and the specific choice of shelf should be determined by the company's specific needs and environment. Before making a decision, we need to consider many factors, including the size of the warehouse, space layout, labor efficiency, operating costs, equipment investment, etc. We should also take into account technological advancements, such as the Internet of Things, artificial intelligence, and automation technologies, which may change the mode and requirements of warehouse management in the future.

Selecting appropriate warehouse shelving requires a deep understanding of business needs and sensitivity to technological trends. Through reasonable shelving selection, we can improve the efficiency of the warehouse, optimize operating costs, and ultimately enhance the overall competitiveness of the enterprise.
