Several different machines can often perform the same type of operation, so an operation can be performed on a part by selecting any of the machines offering that same function. Moreover, many machines are not limited to performing only one type of operation on a part, so a part can be fabricated using a single machine to perform more than one operation. Some papers have discussed alternative routings and machines, but have not considered a machine that can perform more than one operation on a part. The concept of using an alternative machine capable of performing several operation types was only introduced into group technology (GT) in 2014. In this paper, the major purpose is to improve traditional GT with considering alternative machines and multiple-operation-type machines. A novel algorithm is proposed. The result can recommend which machine can be used to provide which type of operation on a specific part. Two numerical examples are presented to compare the algorithm with others. Especially, there are sixty-four resolutions that could be suggested to the manager in numerical example one. The traditional GT algorithm cannot solve this problem. Occasionally, more than one result with the same GT efficiency can be provided.

多个不同的机器通常可以执行相同类型的操作，因此可以通过选择提供相同功能的任何机器来对零件执行操作。而且，许多机器不限于对零件仅执行一种类型的操作，因此可以使用单个机器来制造零件以执行多于一个的操作。一些论文讨论了替代 布线和机器，但尚未考虑可以对零件执行多个操作的机器。使用能够执行多种操作类型的替代机器的概念仅在2014年才引入到群组技术（GT）中。在本文中，主要目的是通过考虑替代机器和多操作类型机器来改进传统GT。提出了一种新颖的算法。结果可以建议可以使用哪台机器在特定零件上提供哪种类型的操作。给出了两个数值示例，以与其他算法进行比较。尤其是，在数值示例一中，可以向经理建议64种分辨率。传统的GT算法不能解决这个问题。有时，可以提供多个具有相同GT效率的结果。
