The Fundamentals of Managerial Economics

Chapter 1: The Fundamentals of Managerial Economics

Accounting cost: the costs most often associated with the costs of producing. Costs that appear on the income statements of firms.

Accounting profits: the total amount of money taken in from sales (total revenue, or price times quantity sold) minus the dollar cost of producing goods or services. Accounting profits are what show up on the firm’s income statement and are typically reported to the manager by the firm’s accounting department.

Constraints: an artifact of scarcity.

Consumer-consumer rivalry: reduces the negotiating power of consumers in the marketplace. When limited quantities of goods are available, consumers will compete with one another for the right to purchase the available goods.

Consumer-Producer rivalry: occurs because of the competing interests of consumers and producers.

Economic profits: The difference between total revenue and total opportunity cost.

Economics: The science of making decisions in the presence of scarce resources.

Ex-dividend date: The value of the firm immediately after its current profits have been paid out as dividends.

Five force framework: Entry; Power of input suppliers; Power of Buyers; Industry Rivalry; Substitutes and Complements.

Incremental costs: The additional costs that stem from a yes-or-no decision.

Incremental revenues: The additional revenues that stem from a yes-or-no decision.

Manager: a person who directs resources to achieve a stated goal.

Managerial economics: the study of how to direct scarce resources in the way that most efficiently achieves a managerial goal.

Marginal analysis: optimal managerial decisions involve comparing the marginal (or incremental) benefits of a decision with the marginal (or incremental) costs.

Marginal benefit: the change in total benefits arising from a change in the managerial control variable, Q.

Marginal cost: the change in total costs arising from a change in the managerial control variable, Q.

Marginal net benefits: the change in net benefits that arise from a one-unit change in Q.

Net present value: the present value of the income stream generated by a project minus the current cost of the project.

Opportunity cost: the cost of the explicit and implicit resources that are forgone when a decision is made.

Present value: the amount that would have to be invested today at the prevailing interest rate to generate the given future value.

Producer-producer rivalry: Given that customers are scarce, producers compete with one another for the right to service the customers available.

Resources: simply anything used to produce a good or service or, more generally, to achieve a goal.
本项目采用C++编程语言结合ROS框架构建了完整的双机械臂控制系统,实现了Gazebo仿真环境下的协同运动模拟,并完成了两台实体UR10工业机器人的联动控制。该毕业设计在答辩环节获得98分的优异成绩,所有程序代码均通过系统性调试验证,保证可直接部署运行。 系统架构包含三个核心模块:基于ROS通信架构的双臂协调控制器、Gazebo物理引擎下的动力学仿真环境、以及真实UR10机器人的硬件接口层。在仿真验证阶段,开发了双臂碰撞检测算法和轨迹规划模块,通过ROS控制包实现了末端执行器的同步轨迹跟踪。硬件集成方面,建立了基于TCP/IP协议的实时通信链路,解决了双机数据同步和运动指令分发等关键技术问题。 本资源适用于自动化、机械电子、人工智能等专业方向的课程实践,可作为高年级课程设计、毕业课题的重要参考案例。系统采用模块化设计理念,控制核心与硬件接口分离架构便于功能扩展,具备工程实践能力的学习者可在现有框架基础上进行二次开发,例如集成视觉感知模块或优化运动规划算法。 项目文档详细记录了环境配置流程、参数调试方法和实验验证数据,特别说明了双机协同作业时的时序同步解决方案。所有功能模块均提供完整的API接口说明,便于使用者快速理解系统架构并进行定制化修改。 资源来源于网络分享,仅用于学习交流使用,请勿用于商业,如有侵权请联系我删除!
