01. Case study 2 “Mechoff - Cells” 1 MECHOFF CELLS - INTRODUCTION - MECHOFF is a small company operating in the field of mechanical components for industrial air conditioning systems. - Demand of SP family products is growing. - The company is interested in accepting the order of a new customer to produce a new product that can be added to the same family. - If this order were accepted, the yearly volume required would be 2000 units for the first two years. - MECHOFF top management would be interested in knowing in which way the company could satisfy the demand internally. After checking the best solution to re-insource milling and grinding processes by keeping a Job Shop configuration of the plant, further considerations can be made: - one of the main goals of the company is to reach stable quality; - another concern of the company is the achievement of shorter lead times; - similar technological routings are required in order to produce many products. Cellular manufacturing may be beneficial for these issues: - Stable quality: quality may be more stable for many reasons (work organization, product routings, …) - Shorter lead times: there is expectation for less WIP than in Job Shop - Similar technological routings: it is the right condition for a cellular manufacturing to be designed, by creating product families with similar technological routings to be performed in the cells. 2 MECHOFF CELLS - INPUT DATA The data are quite the same of the job-shop case. Note that there is an expectation of setup time reduction, with respect to the Job Shop case: product families are similar and universal fixtures could be designed as a result of a standardization project. - The human coefficient has been fixed to 0.94. [for the job-shop it was 0.96] - The average scrap rate is…
