In addition, your security level calculation formula can be fully optimized by taking into account the gaps in your supply chain that often affect your business, for example.B. Your order time, defect rates and order quantity requirements. The main objective of security stocks is to absorb variability in customer demand. In fact, production planning is based on a forecast that is (by definition) different from actual demand. By integrating these fluctuations, the level of security improves the level of customer service. Z represents your desired level of service. You need to determine this level for each product. This figure represents the cost of storing a given product by a company compared to the missed sales opportunities resulting from a stock. As a result, this figure varies from company to company, as the cost of missed sales opportunities varies from company to company. Rate too low, and you will have stocks that can lead to disgruntled customers. Although there are variations, we have provided below the simplest security formula as well as a step-by-step guide to implementation. Assuming that requirements during consecutive unit periods are independently distributed and identical random variables from a normal distribution, the security level can be calculated as follows: Ordering an additional product or security stock is a way to avoid inventory. Safety stoc Inventory is the buffer space in your inventory that protects you if: The level of service takes into account the number of destockings allowed per year.
For example, the formula we provided earlier (Safety Stock Formula – Z × `LT × D avg) is the simplest method for calculating the level of safety. It is equal to the cost of the missing service levels compared to the payment of the additional security inventory. But there are still ways to optimize the formula for your business. and the expected number of units that are not in stock during a command cycle is indicated by the „L (z) position.  A Business Resource Planning System (ERP) can also help an organization reduce its security. Most ERP systems offer a kind of production planning module. An ERP module like this can help a company develop very accurate and dynamic revenue forecasts, as well as revenue and operating plans. By making more accurate and dynamic forecasts, a company reduces its likelihood of producing insufficient inventory over a period of time and should therefore be able to reduce the level of security required.  In addition, ERP systems use established formulas to calculate appropriate safety levels based on previously developed production plans.
While an ERP system allows an organization to assess an adequate level of security, the ERP module must be designed to effectively pre-serve the requirements.  Security actions play an important role in reducing some of the co-directing risks inherent in your business. To keep your business ahead of unexpected events, you`ll receive the necessary buffer between a potential inventory and the arrival of inventory. The amount of security inventory an organization has at its disposal can have a dramatic impact on its business. Too much security can result in high storage costs. In addition, products stored for too long can be corrupted, dilapidated or broken during the storage process. Lack of security can lead to lower sales and, consequently, increased customer sales. It is therefore essential to find the right balance between too much and too little security.
