Define the following terms with an example

  1. Constant service time model
  2. Queuing theory
  3. Critical path analysis
  4. Sensitivity analysis
  5. Hungarian method

 

Expert Solution
Step 1

1. Constant service time model:

The single-server model with Poisson arrivals and constant service times is used most frequently for systems with automated equipment and machinery

  1. Constant service times occur with machinery and automated equipment
  2. Constant service times are a special case of the single-server model with general or undefined service times

We can calculate probability that no customers are in the system with the below formula:

Step 2

2. Queuing theory :  

It's a mathematical study of the formation, function, and congestion of waiting lines, or queues.

At its core, a queuing situation involves two parts.

  1. Someone or something that requests a service—usually referred to as the customer, job, or request.
  2. Someone or something that completes or delivers the services—usually referred to as the server.

 Queuing discipline refers to the rules of the queue, for example whether it behaves based on a principle of first-in-first-out, last-in-first-out, prioritized, or serve-in-random-order.

3. Critical Path Analysis:

An effective Critical Path Analysis can make the difference between success and failure on complex projects. It can be very useful for assessing the importance of problems faced during the implementation of the plan.

Critical Path Analysis is an effective and powerful method of assessing:

  • What tasks must be carried out.
  • Where parallel activity can be performed.
  • The shortest time in which you can complete a project.
  • Resources needed to execute a project.
  • The sequence of activities, scheduling and timings involved.
  • Task priorities.
  • The most efficient way of shortening time on urgent projects.
