Basic Excercise
A small manufacturing company is currently designing a new production system, organized in job shops. It is installing 3 different departments (M1, M2, M3), which will serve to produce at least 3 types of product (A, B, C). We have the following information: Product Production process (Department, Cycle Time [min / pcs]) Average annual demand
Job-Shop
-> DEF: working stations are organized in groups of similar stations in terms of implemented technology (it gives the name to the department). -> CHAR: Outline: General Features -> CHAR: -> When a product is introduced in the product portfolio => Production process has to be developed. -> The technological office is in charge of
