Reducing waste and ecological impacts through a sustainable and efficient management of perishable food based on the Monte Carlo simulation
2019
Abstract In today’s competitive global market it is mandatory to improve warehousing operations integrating economic, environmental and social aspects. The recent advancement in monitoring technologies can greatly improve the performance of the food supply chain reducing product loss. In particular, in the perishable food supply chain, initially inventory operations are critical because they manage the material flows in very variable conditions. The deterioration level of the products as well as the market demand are the main factors that can influence warehouse strategy. This research aims to consider the application of sustainability principles in the context of warehouse storage, evaluat…
A combined interval-valued ELECTRE TRI and TOPSIS approach for solving the storage location assignment problem
2019
Abstract Efficiency and effectiveness of logistic activities, in general, and of distribution networks, in particular, are largely influenced by the way warehouses operate as nodes of these networks. In recent years, warehouse management has undergone major changes due to the increase of e-commerce and competition in time-reduction. Despite that, logistic costs of warehouse processes (e.g. receiving, storage, order picking and shipping, etc.) are still often high. Referring to the order picking process, related activities may be optimized by a proper assignment of products to storage locations. In the literature, this problem is known as Storage Location Assignment Problem (SLAP). Due to th…
Coverage analysis of RFID indoor localization system for refrigerated warehouse based on 2-D Ray tracing
2010
Due to the ever increasing diffusion of Radio Frequency IDentification (RFID) in logistic processes, the localization of the tags in the environment is becoming an important feature for many RFID-based inventory management systems. RFID-based Location system will allow offering value-added services logistics operators, and RFID tags can be used for more than just labeling items. This paper proposes a Received Signal Strength (RSS) based positioning system for perishable products equipped with active UHF RFID tags inside a refrigerated warehouse (4C°). The major performance metrics of interest for indoor positioning systems are the accuracy and the precision in estimating signal strength wit…
Evaluation of routing policies using an interval-valued TOPSIS approach for the allocation rules
2021
Abstract The success of warehouse management in a supply chain widely depends on an efficient and effective retrieve of customer orders, which is known as the picking process. This paper investigates various routing policies of pickers under two different allocation methods of items in a warehouse of fixed layout, and evaluates their performance in terms of the resulting travel distance by means of a simulation approach. The allocation strategies taken into account are the random storage and a multi-criteria approach, called Interval-Value TOPSIS (IV-T), which is expressively proposed in this paper as a new way to solve the storage allocation problem of items in a warehouse. Because of the …
