10. Factory Physics 01. Factory Physics 1 WORK CONTENT MODEL EXERCISE 1 The VITE & DADO Spa company is specialized in the production of metal parts for the oil & gas sector. Due to the growing of its the market, the company decided to install a new production system to realize some specific products. The new system will be configured as a flow shop with two shops (R1 and R2) where different machining operations will be carried out thanks to dedicated machines (M1 for R1 and M2 for R2). In the first shop metal parts are cut; in the second shop drilling operations will be carried out. The two shops will process different products and a buffer will be located between the two shops. The capacity of the buffer can be considered “infinite”. The following are the data about production mix (in terms of product type, demand and lot size). The mix will be realized homogeneously along the year. Please, notice that opening time will be 7 hours on 200 days per year (SCD, Shop Calendar Day). Product type Demand (pieces/year) Lot size (pieces/order) X 5.000 20 Y 10.000 40 Z 8.000 50 Working time and setup time are provided in the following tables. Product Working time M1 machine (min/piece) Working time M2 machine (min/piece) Product Setup time R1 shop (min/order) Setup time R2 shop (min/order) X 3 10 X 3 10 Y 4 14 Y 3 7 Z 5 11 Z 3 8 Using the Work Content model, you are required: 1. To determine the average daily Work Content for each shop; The work content model is considering also the dynamism of the production system 2. To determine the number of resources (i.e. number of machines) for each shop, which be needed to satisfy the planned demand; -> design the job shop 3. To identity clearly the bottleneck of the system, in the assumption that the required annual demand could be…
