Energy efficiency optimisation in supply chain networks: impact of inventory management

This research study was conducted with the purpose of understanding the impact of COVID-19 on the logistics segment and the associated disruptions in the food supply chain. In the current times, the entire world is challenged by a disease called coronavirus or popularly known as Covid-19. In December 2019, Wuhan in China reported the first case ever. COVID-19 has heavily affected the supply chain networks, logistics in particular. Markets and firms are connected by Logistics companies through the provision of different services, including multimodal transportation, freight forwarding, warehouse management, and inventory management. A diverse pool of logistics players across the world have been impacted owing to the current state of the pandemic. This paper analyzes the disruptions in the movement and delivery of essential food items and how resilient a supply chain should be during such periods of crisis. An experiment was carried out to understand the factors affecting the food essentials delivery to the local kirana stores. For this, a survey of 200 respondents (kirana shop owners) was conducted with the help of a 14-item questionnaire. Factor analysis was the tool used to analyze the results and the software used was SPSS. The outcome of the analysis showed that 5 factors were extracted which tried to explain the 14 variables used in the survey which were afflicted due to the coronavirus pandemic.

Over the last several decades, practitioners have used the Square Root of N (SQRTN) and the Portfolio Effect models to develop estimates of the change in finished goods inventory investment that will result from potential consolidations of existing supply chain networks. The relative simplicity of these two models has made them commonly used tools of consultants and practitioners. However, what is often overlooked or ignored in practice is that these models may or may not provide accurate projections, and that there are limitations to the range of problems which these models can address. In this paper, we evaluate the accuracy of projections made by the SQRTN and portfolio effect models under a variety of network conditions, and we provide guidance on when and how practitioners can both use and supplement these models. Our evaluations are based on the results of simulation studies which we conducted for this paper as well as many years of inventory management practice in private industry.

Key Issues

Radio Frequency Identification (RFID) has been used since the Second World War to identify “friend or foe” aircrafts. It has become an enabling wireless technology that is widely used in a number of application areas, such as product tracking through manufacturing and assembly, inventory control, and supply chain management (SCM). By 2006, Wal-Mart used RFID for all of its suppliers. The use of RFID in supply chain networks has allowed Wal-Mart to create value through greater visibility in its networks, higher product velocity, reduce human error and labor cost, and more efficient inventory management, which led to the achievement of Quick Response (QR) and improved Customer Relationship Management (CRM) in the supply chain. However, RFID system challenges and uncertain Return-On-Investment (ROI) must be overcome to fully achieve these objectives. This paper introduces RFID technology and its key components and concepts, and presents an RFID middleware solution called FlexRFID that achieves the maximum benefits of RFID technology independently of the interested backend applications. This paper illustrates how RFID technology is used to solve the main problems in SCM, the advantages and key issues when implementing RFID in SCM networks, and the relationship between RFID and the main SCM processes.

Vehicle Capacity

The article presents a special modification of the EOQ formula and its application to the accounting of the cargo capacity factor for the relevant procedures for optimizing deliveries when renting storage facilities. The specified development will allow managers to take into account the following process specifics in the format of a simulated supply chain when managing inventory. First of all, it will allow considering the most important factor of cargo capacity when optimizing stocks. Moreover, this formula will make it possible to find the optimal strategy for the supply of goods if, also, it is necessary to take into account the combined effect of several factors necessary for practice, which will undoubtedly affect decision-making procedures. Here we are talking about the need for additional consideration of the following essential attributes of the simulated cash flow of the supply chain: 1) time value of money; 2) deferral of payment of the cost of the order; 3) pre-agreed allowable delays in the receipt of revenue from goods sold. Developed analysis and optimization procedures have been implemented to models of this type that are interesting and important for a business. This — inventory management systems, the format of which is related to the special concept of efficient supply. We are talking about models where the presence of the specified delays for the outgoing cash flows allows you to pay for the order and the corresponding costs of the supply chain from the corresponding revenue on the re-order interval. Accordingly, the necessary and sufficient conditions are established based on which managers will be able to identify models of the specified type. The purpose of the article is to draw the attention of managers to real opportunities to improve the efficiency of inventory management systems by taking into account these factors for a simulated supply chain.
