THE SUPPLY CHAIN MANAGEMENT & OPERATIONS ANALYSIS
Introduction on Supply Chain management and Operations
Production flow management: the whole process of programming, executing and controlling the
production. Aggregate planning: goals, time horizon, actors and degree of detail. The Master Production Schedule (MPS): philosophy, use and form.
THE MATERIAL REQUIREMENTS MANAGEMENT ALONG THE SUPPLY CHAIN
Materials management: target and different strategies. Material Requirement Planning (MRP): Philosophy,
Benefits, Application Limits, Inputs Required, available Software. MRP closed loop systems.
Just in Time (JiT): philosophy, benefits, application limits. Application requirements. Replacement systems: Economic Order Quantity (EOQ-ROP) models and Fixed Reorder Time. The definition of the reordering level (ROP). Safety Stock (SS): goal and numerical sizing
SCHEDULING OF PRODUCTION SYSTEM ALONG THE SUPPLY CHAIN
Production scheduling: goals and definitions. The different types of production systems. Parameters for scheduling performance evaluation. Load rules (EDD, SPT, LPT, MST, etc.). Models and algorithms for scheduling single machines, parallel machines (identical and
The course is organized in frontal lectures in which the basic elements of the various parts of the program are presented. Many lessons devoted to the resolution of exercises and specific problems follow theoretical presentations of each topic. That underlines the applied nature of the discipline and aims to acquire the method, i.e. the ability to translate in mathematical language a concrete problem to determine its solution then applicable in industrial realities.
The final examination consists of 2 numerical exercises and 2 theoretical questions about all the developed program. All the exercises and questions must be sufficient as necessary conditions to consider the sufficient the whole exam.
Comprehension of all course contents related to the manufacturing and assembly systems.
Skills in applying the abovementioned knowledge to industrial complex case studies where the manufacturing/assembly system has a central role for the company.
Ability in technical/economical profitability evaluation of the industrial investment.
