Implementation of Lean Warehousing to Reduce the Level of Returns in a Distribution Company In this study, the problem of high levels of returns of orders to be dispatched, affecting distribution companies of the mass consumption sector, was analyzed. For this reason, the study was carried out for the company AT, which presents an index of 12.10% returns, equivalent to  158,061.69 in lost sales (rejected products), due to the following causes: orders arriving outside the established reception time window (50.71%), incomplete orders (30.57%) and orders arriving in poor condition (18.72 %). Lean Warehousing techniques were used as a practical tool to introduce good and efficient practices in the company. As a standardized framework, the company introduced three stages for the implementation of Lean Warehousing: xe2x80x9ccreate stability,xe2x80x9d xe2x80x9ccreate flow,xe2x80x9d and xe2x80x98make flow,xe2x80x9d in the warehouse. The implementation was carried out for the three stages by means of a pilot, taking as a baseline the following indicators identified by the VSM tool: picking time (5 hours), percentage of orders left unattended due to lack of stock (28.64%) and the percentage of nonconforming orders due to expiration (25.5%). At the end of the implementation, the picking time was reduced to three hours, the percentage of orders left unattended due to lack of stock to 22%, and the percentage of nonconforming orders due to expiration fell to 20%. In this way, the level of rejections was reduced to 5.5% by improving the gross margin of the company. The result will be used as a baseline and example for future implementations to the rest of the distributors of the sector.

Decision Bias in the Newsvendor Problem: On the Comparison of Managers and Students as Newsvendors with Decision Support System as Debiasing Strategy A growing number of studies in the newsvendor problem provided evidence that subjectsu0027 ordering behavior deviates from the optimal order quantity. Furthermore, almost all existing studies only engage students as subjects, and it leaves an essential question of whether the insights of those studies can be applied in real business practices. In this empirical study, we experimented with investigating decision biases in the newsvendor setting and presenting a structured comparison of the order decisions made by managers and students. We also proposed a Decision Support System as a debiasing strategy to prevent the order decision bias. To provide a piece of evidence about the effectiveness of the proposed DSS, we experimented with comparing the ordering behavior, before and after DSS implementation. This study found that both managers and students showed demand chasing bias, but the magnitude of the bias differed significantly. This study also showed that an informational DSS generally improved inventory decisionmaking performance in terms of adjustment behavior and longterm profitability.
