Análise de estoque de uma empresa atuante no comércio de madeira para construção civil

Abstract

This study was developed in conjunction with a small enterprise, which cuts and sells wood used primarily in civil construction for the assembly of roofs. The principal objective consists of applying methods, concepts and stock-related tools in a manner to improve the company’s stock management process and to better assist it in its decision making. The applied research is exploratory, descriptive, and predominantly quantitative where data was collected, transformed and analyzed to generate quantitative and objective results. A bibliographical review was conducted on the principal approaches concerning analysis and stock management, in addition to historical data collecting and its treatment. Finally the interpretation and critical analyzes of results was performed considering the company real context. The demand database involves the monthly sales history, considering the cubic meter as unit measure, from January to December of 2015, composing a sample of 48 elements. The detailed sales data comprises a sample of 3440 elements, and the receiving data of goods, a sample of 4830 elements. The descriptive statistics and time series model was used to verify the demand’s behavior and the relationship between the stores as well. Then, the existence of benefit in stock aggregation is tested just as well the applicability of Economic Order Quantity (EOQ), other than deciding on batch size. The analysis of the detailed data of goods is realized, decomposing the piece in its dimensions of length and width. The hypotheses subjected to proof are concerned with the possible superiority of objective methods of stock analysis in relation to purely subjective and intuitive methods.
