Objectives
THE COURSE AIMS TO PROVIDE TOOLS TO SUPPORT THE MODELING AND OPTIMIZATION OF THE TECHNICAL AND ECONOMIC PERFORMANCE OF THE PRODUCTION AND LOGISTICS SYSTEMS THROUGH A REVIEW OF QUANTITATIVE METHODS TO SUPPORT SYSTEM DESIGN AND IMPROVEMENT, REAL CASES ON WHICH MULTIPLE TECHNIQUES WILL BE USED MODELING IN ORDER TO SOLVE THE PROBLEM. THE MOST IMPORTANT APPLICATION CONTEXTS WILL BE: LOGISTICS NETWORKS, LOGISTICS AND PRODUCTION SYSTEMS CHARACTERIZED BY FLEXIBILITY IN RESOURCE USAGE AND VARIABILITY IN PRODUCTION MIXES AND PROCESS REQUIREMENTS.

THE MAIN SKILLS WILL BE: HOW TO USE THE CAUSE-EFFECT DIAGRAM AND PARETO DIAGRAM FOR FORMULATING A PROBLEM, SCHEMATIZING A PROCESS, USE A PM SOFTWARE TO SCHEDULE A SIMULATION PROJECT, USE IDEF0 AND FLOWCHART FOR FORMAL DEFINITION OF A MANUFACTURING SYSTEM, USE STATISTICAL TESTS TO IDENTIFY SAMPLING DATA SOURCE DISTRIBUTIONS (PROCESSING TIME, ORDER ARRIVAL, ETC.), USE A SIMULATION ENVIRONMENT TO IMPLEMENT A DISCRETE EVENT SIMULATOR, REALIZE THE ANIMATION TO VERIFY THE SIMULATOR OPERATION, USE STATISTICAL TESTS TO DETERMINE WHETHER TWO SETS OF DATA ORIGINATE FROM THE SAME DISTRIBUTION, DESIGN AN EXPERIMENTAL CAMPAIGN, DETERMINE THE DURATION OF RUNS AND TRANSIENTS, DETERMINE THE NUMBER OF REPLICATIONS FOR OBTAINING THE RIGHT ACCURACY, ANALYZE THE RESULTS USING PARAMETRIC AND NON-PARAMETRIC STATISTICAL TESTS AND EVALUATE THE MANAGEMENT ALTERNATIVES TO IMPLEMENT.
Prerequisites
KNOWLEDGE OF GENERAL ASPECTS FOR THE DESIGN AND MANAGEMENT OF INDUSTRIAL PLANTS.
BASIC STATISTICAL AND PROGRAMMING KNOWLEDGE.

EXECUTION AND ANALYSIS OF RESULTS (2H T + 4H E): CALCULATION OF THE NUMBER OF REPLICAS, TRANSITIONAL LENGTH, RUN DURATION, WELCH APPROACH, DUNCAN MULTIPLE RANGE TEST, AUTOCORRELATION AND BATCH METHOD, EXERCISES AND APPLICATIONS.
Teaching Methods
THE COURSE INCLUDES THEORETICAL LESSONS FOLLOWED BY EXERCISES AND PRACTICAL APPLICATIONS DEVELOPED IN THE CLASSROOM AND / OR IN THE LAB THROUGH THE USE OF THE PERSONAL COMPUTER. BEFORE EACH LESSON, SLIDES (IN ELECTRONIC FORMAT) AND APPLICATION SOFTWARE (OPEN SOURCE OR LEARNING EDITION) ARE PROVIDED.
Verification of learning
THE EXAMINATION PROVIDES FOR A WRITTEN TEST OF 2 HOURS. THE WRITTEN TEST CONSISTS OF A DESCRIPTION OF A PROBLEM AND A MINIMUM OF FOUR QUESTIONS TO VERIFY THE STUDENT'S ABILITY TO ACQUIRE THE MAIN SKILLS PROVIDED BY THE COURSE. EACH QUESTION IS ASSIGNED A MAXIMUM SCORE OF 5 TO 15 POINTS. THE SUM OF THE HIGHEST SCORES IS 32. SUFFICIENCY IS REACHED AT LEAST 18 POINTS. HONORS CAN BE ATTRIBUTED OBTAINING AT LEAST 30 POINTS AND DEMONSTRATING, EVEN DURING THE ORAL TEST, GOOD COMMAND AND INTERRELATIONSHIP BETWEEN THE TOPICS DISCUSSED.
