摘要

本研究旨在通过运筹学建模前后两种情景，分析某木工企业生产框架的经济可行性。考虑到30年的时间跨度，对年度成本和收入进行了量化。经济分析包括以下标准:净现值(NPV)，等价周期价值(EPV)和收入成本比(R/C)。该模型是在对标准生产进行分析后应用的，目标函数是基于每种产品的生产数量使公司利润最大化。标准生产的所有评价指标均具有经济可行性，而实施运筹学的NPV和EPV指标提高了57.54%，R/C比提高了11.29%。在建模后应用敏感性分析时，我们注意到，即使人工成本或木材价格增加10%，与建模前未应用敏感性分析的标准生产场景相比，NPV指标的值也更高。

OPTIMIZATION OF ECONOMIC INDICATORS IN A CARPENTRY COMPANY THROUGH INTEGER PROGRAMMING

ABSTRACT This study aimed to analyze the economic feasibility of manufacturing frames in a carpentry company through two scenarios, including the production before and after modeling using operational research. The annual costs and revenues were quantified considering a horizon of 30 years. The economic analysis included the following criteria: Net Present Value (NPV), Equivalent Periodic Value (EPV) and Revenues Cost Ratio (R/C). The modeling was applied after analysis of the standard production using an objective function to maximize the company’s profit based on the quantity of each assortment to be produced. The standard production showed economic feasibility for all evaluated indicators, however implementing the operational research provided an increase of 57.54% for the NPV and EPV indicators, and 11.29% for the R/C ratio. In applying the sensitivity analysis after modeling, it was noticed that the value obtained for the NPV indicator was higher, even with a 10% increase in labor costs or in the price of wood, when compared to the standard production scenario before the modeling and without applying sensitivity analysis.
