What can you define to ensure that production flow only happens in suitable and physically connected tanks?

Your project uses process orders for the production of liquid chemicals.

What can you define to ensure that production flow only happens in suitable and physically connected tanks? Note: There are 2 correct answers to this question.
A . Resource matrix
B . Resource network
C . Resource hierarchy
D . Resource selection

Answer: B, D

Explanation:

A resource network is a business object in PP/DS that defines the allowed directed connections between two or more resources. A directed connection means that the connection from Resource 1

to Resource 2 is not the same as the inverse connection from Resource 2 to Resource 1. You use this object to model existing production constraints more precisely, with the objective of creating a finite and technically feasible production schedule. Resource networks simplify the modeling of resource restrictions for consecutive operations or orders1

A resource selection is a business object in PP/DS that defines the criteria for selecting a suitable resource for an operation or an order. You use this object to specify the characteristics, attributes, and capacities of the resources that can be used for a particular production process. Resource selection allows you to optimize the resource utilization and reduce the setup times and costs2 A resource matrix is a business object in PP/DS that defines the relationships between different resources based on their characteristics and attributes. You use this object to determine the setup times and costs for changing from one resource to another. Resource matrix allows you to model the setup effort and expense more accurately and improve the production efficiency3

A resource hierarchy is a business object in PP/DS that defines the structure and sequence of resources that are used for a production process. You use this object to represent the logical and physical dependencies of the resources and to control the scheduling and sequencing of the operations or orders. Resource hierarchy allows you to model the production flow and capacity more realistically and ensure the technical feasibility of the production plan.
