Riassunto analitico
The objective of this thesis is the development and application of a software tool to support an Assembly Line Balancing problem, minimizing the number of stations used to allocate the elementary operations identified in the whole process, in accordance with an assigned cycle time. The assembly phase has always been one of the most critical one within the entire cycle of the product realization, therefore, has led many companies to search for the best methods for solving balancing problems. In this paper the problem is dealt with five different algorithms: Largest Candidate Rule, Most Following Task, Ranked Positional Weight, Kilbridge & Wester, Kottas Lau, all implemented both in the case of a “single model” line which in the case of a “mixed-model” line. To solve the problem, therefore, in this thesis it was decided to use an Excel spreadsheet, which automating the largest possible number of calculations also allows us to solve problems with a higher number of transactions. As a practical case, in the “single model” case was showed the assembly process of a gearbox VF 30 by Bonfiglioli, whose assembly process can be summarized in 21 elementary operations. To extend the application to the “mixed model” case, this product will be attached to the assembly process of a pole switch, which consists of 11 elementary operations.
