## 2 Literature Review
### Configuration Selection
#### 2.2.2 Configuration Selection Criteria  
The selection criteria are the indicators that must be improved to achieve the objectives defined by the company. These criteria are grouped into two families divided into a set of levels. The first family consists of generic selection indicators which include different performance indicators such as cost, time and reactivity of machines/systems. On the other hand, the second family is composed of indicators related to reconfigurability which consists of three levels of criteria: time and cost of reconfiguration, reconfiguration effort and reconfigurability characteristics. Figure 1 shows the different levels of each indicator family. 1. The generic indicators  
This family of selection indicators are those that can be chosen for any selection problem related to the supply chain. Generally, these indicators refer to the performance of the supply chain configuration regardless of its ability to adapt to market changes. These indicators represent selection criteria based on cost, time and capacity. * The cost: this criterion is considered as the most important one for configuration selection, it includes several types of costs such as investment cost related to expenses for machines or system/supply chain entities such as the implementation of production \begin{table}

The criteria that define this indicator level are, for example, operational capacity, availability, productivity, etc. * The reconfigurability indicators  
This family of indicators addresses criteria related to supply chain reconfigurability parameters. The authors of [20,21] defined reconfigurability as the ability of the supply chain to change its structure and its functions to adapt to new changes and to cope with market disruptions. In fact, reconfigurability allows judging the supply chain's ability to adapt quickly and cost-effectively to market changes. In this context, three main criteria were used to choose the most reconfigurable configuration, namely the cost/time of reconfiguration, reconfiguration effort and reconfigurability characteristics. * The cost/time of reconfiguration: the reconfiguration cost is the cost of changing the configuration (adding, deleting or changing the entities that compose it), while the reconfiguration time is the time needed to reach the new configuration.
