运筹学是现代管理学的一门重要专业基础课。它是20世纪30年代初发展起来的一门新兴学科，其主要目的是在决策时为管理人员提供科学依据，是实现有效管理、正确决策和现代化管理的重要方法之一。该学科是一应用数学和形式科学的跨领域研究，利用统计学、数学模型和算法等方法，去寻找复杂问题中的最佳或近似最佳的解答。运筹学经常用于解决现实生活中的复杂问题，特别是改善或优化现有系统的效率。 研究运筹学的基础知识包括实分析、矩阵论、随机过程、离散数学和算法基础等。而在应用方面，多与仓储、物流、算法等领域相关。因此运筹学与应用数学、工业工程、计算机科学、经济管理等专业密切相关。( Operations research is an important basic course of modern management. It is the beginning of the 1930s developed a new discipline, its main purpose is to provide management decision-making scientific basis, it is to achieve effective management, one of the important decisions the right way and modern management. The interdisciplinary research discipline is a form of applied mathematics and science, using statistical, mathematical models and algorithms and other methods to find the complex issues in the best or near-best solution. Operations research is often used to solve complex problems in real life, especially to improve or optimize the efficiency of existing systems. Basics of operations research include real analysis, matrix theory, stochastic processes, discrete mathematics and algorithms base and the like. In the application, more associated with warehousing, logistics, algorithms and other fields. Therefore, operations research is closely related to applied mathematics, indu)
