Probability Distributions
Definition: Assignment Problem
The assignment problem is a special type of problem which deals with the allocation of various resources to various activities on a one-to-one basis.
Key Points: Hungarian Method
The Hungarian Method is an optimisation algorithm that solves an Assignment Problem.
Step 1: Row Reduction
Step 2: Column Reduction
Step 3: Assignment
Step 4: Cover Zeros
Step 5: Create Additional Zeros
Definition: Unbalanced Assignment Problem
An unbalanced assignment problem is one in which the number of resources is not equal to the number of activities i.e. the cost matrix of an assignment problem is not a square matrix (no. of rows ≠ no. of columns).
Definition: Maximization Problem
A maximization assignment problem is an assignment problem in which the objective is to maximize total profit, revenue, or effectiveness instead of minimizing cost.
This conversion to a minimisation problem can be done in either of the following ways:
- Subtracting all elements of the matrix from the largest element in the matrix, or
- Multiplying all the elements of the matrix by -1.
Definition: Restricted Assignment Problem
An assignment problem involving restrictions on allocation due to personal, technical, legal or other reasons is called a restricted assignment problem.
Definition: Alternative Optimal Solution
An alternate (multiple) solution exists for an assignment problem when the final assignment matrix contains more than the required number of zeros.
Definition: Sequencing Problem
A sequencing problem is a problem in which the order or sequence of processing a set of jobs on one or more machines is to be determined so as to minimize the total processing time or overall completion time.
Key Points: Types of Sequencing Problems
- n jobs on 2 machines
-
n jobs on 3 machines
-
2 jobs on m machines
Definition: Total Elapsed Time
It is the time required to complete all the jobs, i.e. the entire task.
or
The total elapsed time is the time between the beginning of the first job on the first machine till the completion of the last job on the last machine.
Definition: Idle Time
Idle time is the time when a machine is available but not being used, i.e. the machine is available but is waiting for a job to be processed.
