Lean model to reduce picking time delays through Heijunka, Kanban, 5S and JIT in the construction sector

Abstract

Delays in the time of preparation of orders in a warehouse of materials and construction tools affect delivery times, which affects the level of service and consequently the loss of customers. This, due to the waste in the existing system such as the lack of planning of the process inputs, inefficient procedures, lack of organization and total cleaning. Therefore, this document proposes the application of a Lean Model of picking based on Heijunka, Kanban, 5S and JIT techniques, to eliminate waste (time, movement and inventory). After proposing the improvements, support was made in a stochastic tool to validate the changes with respect to the current situation. Consequently, significant improvements were observed, particularly in the collector's load, reducing its load by 56.29%, eliminating the waiting times for requirements and increasing the orders served. This leads to the improvement of the productivity of the picking operation at 47.07%, resulting in timely deliveries.

Improving Warehouse Management Processes to Ensure On-Time Delivery of Paprika-Based Products

“…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].…”

A heijunka study for the production of standard parts included in a customized finished product

“…The result of the simulation experiment was the identification of a batch size of vehicles with minimum work-in-progress on a production floor and shortest lead time. de la Cruz et al [ 19 ] proposed a Lean model of picking in a warehouse based on heijunka, Kanban, 5S and JIT techniques. The model was subject to assessment using a simulation study.…”
