越来越多的机器正在增加其灵活性，以便能够用相同的工具生产不同的产品。在这种情况下，有必要有快速和准确的方法来评估系统的性能。本文提出了一种生产Z种不同类型产品的生产系统性能评价的近似解析方法。所提出的方法是基于复杂的系统分解成一组更简单的积木，每个积木由两台机器和Z同质缓冲区形成。构建块的集合对原始系统的整个行为进行建模。每个积木块的性能进行评估，通过使用聚合技术应用到两个机器的生产线，其中几个产品的行为是由一个聚合产品建模，从而简化了分析的复杂性。本文的数值结果表明，该方法提供了准确的结果。
More and more machines are increasing their flexibility so as to be able to produce different products with the same tooling. In this context, it is necessary to have fast and accurate methods to evaluate the system performance. This paper presents an approximate analytical method for the performance evaluation of production systems in which Z different types of products are produced. The proposed method is based on the decomposition of the complex system into a set of simpler building blocks, each one formed by two machines and Z homogeneous buffers. The set of building blocks models the whole behavior of the original system. The performance of each building block is evaluated by using the aggregation technique applied to two-machine lines in which the behavior of several products is modeled by an aggregate product, thus simplifying the complexity of the analysis. The numerical results reported in this paper prove the method provides accurate results.
