“…Evaluating the operational and strategic issues, 5 planning and decision problems are identified: distribution design, storage allocation, zoning (the division of the warehouse into other zones), batching (the accumulation of smaller orders into larger lots) and finally the routing through the storage area [26].…”

“…Storage design and 5S: The warehouse design follows the design of the authors [26] [34] who propose a U-shaped design and taking into account the considerations involved in the storage of paprika, what is sought is the reallocation of spaces for an existing structure, improve the flow of materials and reduce the time and preparation of orders. As for the 5S technique, it will be applied in order to order the spaces pre and post implementation of the warehouse design, create a culture of cleanliness and standardize the new preparation processes [35] [36].…”

On-time deliveries are considered a strategic factor for the market positioning of companies. Such is the case of the company under study where only 76.5% of orders arrive on time, compared to 90.2% of companies in the same sector in Colombia. The causes of the problem are an inadequate management of the raw material warehouse processes, causes such as the lack of organization of the physical space that lengthen the preparation of orders, inefficient inventory control processes at the entrance and inside the warehouse and inadequate handling. These have caused losses of raw materials due to pyrolysis, shortages, and delays in production and therefore the rescheduling of the delivery date of orders. In order to improve these processes, we implemented the 5S and a redesign of the warehouse, simple sampling, ABC analysis, cyclic counting and EOQ model. As a result, an increase in orders delivered on time of 12.53%

“…Plonka proposes the application of autonomous mobile robots for the automation of transporting trolleys in hospital logistics, aspiring to relieve the human workforce from frequently carrying high loads and performing repetitive tasks [63]. When focusing on the evaluation of practices in work systems, Diefenbach et al investigate the physiological stress of handling bins on different levels of a tow train wagon by a computational study that proposes an optimal storage plan, which can significantly ease the physiological burden on the workforce [64]. Another research stream within workplace practices in physical ergonomics is represented by studies dealing with wearable sensors for continuous health monitoring, movement analysis, or rehabilitation [65].…”

Logistics Work, Ergonomics and Social Sustainability: Empirical Musculoskeletal System Strain Assessment in Retail Intralogistics

et al. 2021

Background: A large proportion of logistics jobs still rely on manual labor and therefore place a physical strain on employees. This includes the handling of heavy goods and physiologically unfavorable postures. Such issues pose a risk for employee health and work capability. This article provides a detailed empirical analysis and a decision process structure for the allocation of ergonomic measures in warehousing and intralogistics processes. Methods: The methodological basis is a load assessment of the musculoskeletal system in retail intralogistics. Based on the established measurements systems CUELA and OWAS, the specific loads on employees are assessed for four typical logistics workplace settings. These are combined with standards for efficient decision rules regarding contracting and developing ergonomic improvements. Results: The results suggest an increased risk of long-term low back injury for the selected four standard work situations in warehousing and likely apply to similar work environments in logistics. Using measures, posture descriptions, and international standards, we show how already few threshold values serve as sufficient conditions to decide if ergonomic interventions are required. Conclusions: The specific contribution is characterized by the combination of literature review results, empirical results, and the identification and discussion of specific mitigation measures. These elements are focused on the highly relevant ergonomic situation of logistics workers and present a unique contribution towards the knowledge base in this field due to the multi-perspective approach.

In a context where companies are striving to produce highly customised goods in small batches and within short lead times, increasing attention is being put on the design and management of part feeding systems. This research is the first to model automated part feeding to supermarkets in a factory environment, considering an innovative technology called vertical robotic storage and retrieval systems. This technology allows automating the storage, picking, and internal transportation activities in an integrated process, thanks to rack-climbing robots roaming in both the shop floor and the storage racks. We develop an analytical model based on the queuing network approach to analyse the system performance, and we use it to perform numerical experiments and to evaluate the design trade-offs with reference to a real case in the automotive industry. Results show that an increase in the number of robots leads to better performance since the positive impact on the response time is stronger than the negative impact on the waiting times of robots at the supermarkets due to congestion. Furthermore, a configuration with multiple small supermarkets improves the efficiency of the replenishment process, compared to a setting with few big supermarkets.
