In supply chain network design, the location of factories, warehouses, and distribution centers is a strategic decision that affects costs. Consequently, companies spend a significant amount of time and resources considering and evaluating alternatives to choose the one that is most suitable for them. The primary objective of managing transportation and waiting lines is to minimize their total costs throughout any service or manufacturing facility. Objectives: Transportation modeling to other situations. The various cost implications and the key features of waiting lines. Employ the various queueing models and understand when and how to use them to calculate optimal queueing solutions, including the psychology underlying waiting lines.

Q1. Can the structure of transportation models be applied to other operations management situations? Please explain it on the example and give me reference's URL link, I will read more details later. Q2. For most waiting line systems, the first-come, first-served (FCFS) rule is the most frequent assumption of queue discipline. I am trying to find example of waiting line systems where this assumption would not be appropriate but I still can't find it. Can you explain it on the some case or example, please and give me reference's URL link, I will read more details later.?
