Basic knowledge related to management.

Basic knowledge about various operations and decision making.

2. Course Overview

This course addresses the management of operations in manufacturing and service

organizations. Diverse activities, such as determining the size and type of production process,

purchasing the appropriate raw materials, planning and scheduling the flow of materials and

the nature and content of inventories, assuring product quality, and deciding on the production

hardware and how it gets used, comprise this function of the company. Managing operations

effectively requires both strategic and tactical skills and is one of the most critical aspects of

an organization. Effective and efficient utilization of resources by an organization determines

its success in the long run and operations management is means to achieve this end. This is

especially true today, when we see that significant competitive advantages occur to firms that

manage their operations effectively.

This subject requires the student to know the basics of engineering mathematics such asMatrix algebra, Laplace Transforms, Fourier Transforms, Differentiation and Integration etc.,Basics of Physics, Basics of Mechanics and basics of Electrical & Electronics engineering &other related engineering fields.

Overview of the Course:

In recent years, the concept of automatic control has achieved a very important positionin the modern technology. Optimization and automation principles are improving the static andtransient behaviors of the control systems. The stability analysis and the design of such controlsystems is the challenge before today’s engineer. The control systems find applications in thewide variety of engineering branches. From this point of view, VTU has introduced a course on“Control Engineering” at VII Semester of Mechanical Engineering branch.

Signal Flow Graphs and use Mason’s Gain Formula.4. Analyze stability of control systems using Nyquist plots, Bode plots and Root Locus

Plots 5. Apply the compensation techniques to improve performance of control systems

Relevance of the Course:

Automatic control systems have played an important role in the advancement andimprovement of engineering skills. Practically, every activity in our day to day life is influencedby some sort of control system. Concept of control systems also plays an important role in theworking of space vehicles, satellites, guided missiles etc. such control systems are now integralpart of the modern industrialization, industrial processes and home appliances. Control systemsare found in number of practical applications in all the engineering disciplines. Hence for anengineer it is absolutely necessary to get familiar with the analysis and designing methods ofsuch control systems. Applications Area:
