Workforce

Java program that optimizes workforce. The program optimizes the workforce capacity to the optimal value based on the number of available seniors and juniors per contract. The input data is of JSON format. For example input data, {"rooms":[35,21,17,28],"senior":10,"junior":6} The program will optimize the input values and generate an outvalue of the format: [ {senior: 3, junior: 1}, {senior: 1, junior: 2}, {senior: 2, junior: 0}, {senior: 1, junior: 3} ]

Optimization Logic

The number of seniors and juniors is taken as the work rate for each of them. If a contractor has 10 seniors and 6 juniors then the work rate of senior resources will be 10 rooms and work rate of junior resources will be 6 rooms. Optimization logic will iterate through the array of structures and keep adding juniors resource until the capacity matches or just exceeds the number of rooms. The team size per contractor is limited based on the structure with the highest number of rooms for cleaning. If a team size has to exceed the limite in order to match the efforts required. Then the iterator for the strucure will start from begning again and one more senior resource will be added to increaseing the performance.

Example, {"rooms":[35,21,17,28],"senior":10,"junior":6} In this contractors data, the highest number of rooms is 35, so the team size will be limited Ceil(35/10) = 4. To match the efforts for 35 rooms. In iteration1 the number Juniors = 5 and seniors = 1 (56 + 110)to satisfy a the efforts for 35 rooms but team size has exceeded 4 so add one more senior and iterate through the array. This iterator completes until the team size is satisfied and the efforts required matched. In this case of 35 rooms the optimized value will be {senior: 3, junior: 1}

Executing the program

This program is built on maven so maven should be installed on the system

1. Clone the repository
2. Open command prompt or terminal and go to the directory in which the project has been cloned.
3. Go to the WorkforceOptimizer folder in the cloned directory
4. Run mvn compile & mvn install
5. Run java -jar target/WorkOptimizer-1.jar

Test Cases

To execute the test cases separately run mvn test

Test case 1 - calculateWorkforceLimitTest

This function calculates the work force limit per team. Example, {"rooms":[35,21,17,28],"senior":10,"junior":6} In this contractors data, the highest number of rooms is 35, so the team size will be limited Ceil(35/10) = 4.

Test Case 2 - RequiredEffortsForStructureTest

This function estimates the efforts based on the number of seniors and juniors. If Total number of seniors = 10 and Juniors = 6 and optimized number Juniors = 5 and optimized number of seniors = 1 then efforts is equal to (56 + 110) = 40

Test Case 3 - optimizeWorkforceTest

This function optimizes the workforce capacity. The optimizeWorkForce function returns an array of array indicating the optimized value (Seniors: Juniors: ) For example, Input data : {"rooms":[35,21,17,28],"senior":10,"junior":6} the function will return an array of array with values [[3,1],[1,3],[1,2],[2,0]]
