Studies on the Expanded Sequence Matrix and its Application in Flowshop Layout
Based on the analysis of current kinds of sequence matrixes, Type 1 and Type 2, an expanded and refined sequence matrix was proposed. Then, based on the optimized expanded sequence matrix, an improved sequence matrix was brought forward, which could be easily written in a normalized form and whose calculation was simple and convenient. With operational rules of combined sequence matrixes defined, this expanded sequence matrixes can also be applied to the problems of mixed production lines. Finally, the improved matrix was successfully applied to an example of flowshop balancing problem, and it was implemented in the Excel environment in an automatic computing way.
