In automotive industry, engineers are working hard to check whether existing constraints are correct and valid combinations are expected among the allowed combinations.However, this is not a trivial task due that the number of variables and the constraints may be very large.The goal of this thesis is to examine feasibility of analyzing and exploring such large data sets to support engineers' work.For this purpose, a two-step strategy has been taken to solve this task.Workload is divided to firstly investigate the feasibility to present big number of string-formatted allowed combinations.The second step is to find techniques that are of value to navigate and query the data.Several terminologies, Cartesian Product, Treemap, etc, are introduced to fulfill the two tasks respectively.The decision on rejection or acceptance of the alternatives are made with the help of graphs and tables.The outcome of the study covers a set of workflows and user cases that describe the principles and results of the proposed solutions.
