Route planning methods for a modular warehouse system

Abstract

In this study, procedures are presented that can be used to determine the routes of the packages transported within a modular storage system. The problem is a variant of robot motion planning problem. The structures of the procedures are developed in three steps for the simultaneous movement of multiple unit-sized packages in a modular warehouse. The proposed heuristic methods consist of route planning, tagging, and main control components. In order to demonstrate the solution performance of the methods, various experiments were conducted with different data sets and the solution times and qualities of the proposed methods were compared with previous studies. It was found that the proposed methods provide better solutions when taking the number of steps and solution time into consideration.

Optimal Materials Handling Equipment and Defective Product Reduction Skills in Enhance Overall Production Efficiency

“…With regard to the category of storage and handling equipment, the regression results indicated that this category has significant influence (β = .589, p < .05) on the defective product reduction skills toward positively enhancing overall production efficiency. The result suggests that the optimal using of storage and handling equipment has a positive impact not only on defective product reduction skills, but also makes the material easily accessible, maximizing the utilization of space, and eliminates factory hazards (Dayıoğlu, 2020). On the other hand, Abu Jadayil et al (2017), Ibrahim et al (2008) confirmed that having suitable storage equipment can help significantly on enhancing overall production efficiency and increasing profitability for the manufacturing organizations.…”

“…These periods are known as brief suspensions during long-term shipping or long-term storage, and they are designed to allow the stock to accumulate (Disha Experts, 2020). The design of each type of storage equipment, in tandem with its use in warehouse design, denotes a trade-off between diminishing handling expenses, by making material easily accessible, and taking full advantage of the utilization of space (Dayıoğlu, 2020). By investigating enhanced efficiency possibilities in storage equipment, most of the firms have designed proprietary packaging in a way that allows products and materials of a certain type to conserve space while in inventory (Disha Experts, 2020).…”

Strategic Roadmap for Adopting Data-Driven Proactive Measures in Solar Logistics

“…Creating flexible, modular routing plans that can be easily adjusted as project scopes expand or contract, typical in large-scale solar projects. This measure is focused more on the planning stage [57].…”

Solution of green simultaneous pickup and delivery vehicle routing problem with time window using metaheuristic methods

“…Lojistik, malların tedarikçilerden müşterilere kadar olan yolculuğunda nakliye ve depolama ile ilgili tüm faaliyetleri içine alan bir fonksiyondur. Bu fonksiyon sayesinde malzeme ve ürünler ilk çıkış noktasından ihtiyaç duyulduğu nihai tüketim noktasına taşınırlar [8]. Üretim ve dağıtımdaki ürünlerin ağırlık ve hacim olarak büyümesi lojistik operasyonlarına ilişkin alanlarda optimizasyon çalışmalarını çok daha önemli hale getirmiştir [9].…”
