Overview

Course Overview Course covers a systems approach to managing activities associated with traffic, transportation, inventory management, warehousing, packaging, order processing, and materials handling. This course is designed to give students a comprehensive understanding of the issues involved in the design of an industrial production system. It will cover the problems in plant location, product analysis, process design, equipment selection, materials handling, and plant layout.

Course Objectives:

• 1. To develop competency for system visualization and design.
• 2. To enable student to design cylinders and pressure vessels and to use IS code.
• 3. To enable student select materials and to design internal engine components.
• 4. To introduce student to optimum design and use optimization methods to design mechanical components.
• 5. To enable student to design machine tool gearbox.
• 6. To enable student to design material handling systems.
• 7. Ability to apply the statistical considerations in design and analyze the defects and failure modes in

Course Outcomes:

• 1. Demonstrate ability to successfully complete Fork Lift Certification to safely and effectively operate in the manufacturing environment.
• 2. Demonstrate proficiency in supply chain operations, utilizing appropriate methods to plan and implement processes necessary for the purchase and conveyance of goods in a timely and cost-effective manner
• 3. It explains about the different types of material handling, advantages and disadvantages. It also suggests the selection procedure for the material handling along with its specifications.
• 4. Need for Material handling also explained with different techniques like Automated Material handling Design Program, Computerized material handling Planning will be dealt.
• 5. The Material handling is explained with models, selection procedure of material handling is depending on different function oriented systems. This also related with plant layout by which the minimization of the handling charges will come down.
• 6. The ergonomics related to material handling equipment about design and miscellaneous equipments.
