INTRODUCTION TO INDUSTRIAL PLANTS Definitions and fundamentals of the main industrial plants. Production systems classification. Service/process auxiliary plants. General schemes of Feasibility Study and Systematic Layout Planning.
FEASIBILITY STUDY Market analysis and demand/ supply forecasting. Best sales volume, production capacity planning. Product study and design. Process planning and process determination. Productive cycles. Auxiliary services needed for the manufacturing process. Best productive set-up. Economic analysis for industrial investments returns, investment criteria.
INDUSTRIAL LOCATION SELECTION Common features, factors and parameters for location choosing. Qualitative and quantitative models in plant location choosing. Optimization procedure with factors analysis and final plant location
MATERIAL FLOW ANALYSIS AND ACTIVITY ANALYSIS Product-quantity analysis. Product-quantity data sheet. Documents for the flow analysis. MAG (Magnitudo) unit of measure of material flow. Flow diagram. Group Technology (GT) & Cellular Manufacturing (CM).
SPACE REQUIREMENTS Analytical models for the determination of space requirement. "Direct calculation method”: equipment requirements in product and process layout. Manufacturing utilization index. The production-oriented line and the average utilization index. Economic value of an industrial resource. Balancing of assembly lines and manufacturing cells: Kottas-Lau algorithm and alternative methods. Buffer sizing in manufacturing and assembly cells. Equipment and employee requirements. Multiple activity chart analysis of multi-machine assignment: employee-machine chart and analytical models (for identical machines). Automated manufacturing cell design: Robot-Machine chart; dynamic simulation for the balancing of a manufacturing cell.
LAYOUT DESIGN Mtehods and tools to support the layout design. Selection of optimal layout. Principal factors for the evaluation of a portfolio of alternative layout configurations.
PROJECT SCHEDULING
Graph theory and project scheduling Evaluation & Review Technique (PERT).
Part 2
Overview of the design and sizing of some service systems
Fluid distribution service
Recalls of mechanical plant engineering: elements and accessories of "piping". Examples of distribution networks (steam, compressed air).
Production service and energy distribution
Recalls on the traditional systems of combined production of electric and thermal energy (steam, with internal combustion engines, turbogas).
Wellness service in the workplace
Recalls on air conditioning systems
Safety service in the workplace
Recalls on noise protection in the workplace. Evaluation of noises and regulations. Didactic methods
- On the whole 90 teaching hours of frontal lessons and training corresponding to 9 ECTS. The main target is to give the student the right approach the dimensioning of facilities inside an industrial plant, according to economical evaluation and technical rules
Learning assessment procedures
- Achievement will be assessed by the means of a final exam. This is based on an analytical assessment of the “expected learning outcomes” described above.
In order to properly assess such achievement the examination is based on a written test, lasting up to three hours including the theoretical and practical development of three arguments, two of which theoretical issues and one numeric - themed application.
The rating is assigned based on the overall assessment of the whole test. Higher grades will be awarded to students who demonstrate an organic understanding of the subject, a high ability for critical application, and a clear and concise presentation of the contents, with particular attention to the use and the comprehension of technical terms, graph and diagrams. To obtain a passing grade, students are required to at least demonstrate a knowledge of the key concepts of the subject, some ability for critical application, and a comprehensible use of technical language.
A failing grade will be awarded if student shows knowledge gaps in key-concepts of the subject, inappropriate use of language and logic failures in the analysis of the subject. Then the exam will result not sufficient if at least one question is not sufficient. Reference texts
