Linear programming (LP)
- Linear programming (LP) in industrial engineering is used for the optimization of our limited resources when there is a number of alternate solutions possible for the problem like material selection.
- The real-life problems can be written in the form of a linear equation by specifying the relation between its variables.
- Linear programming is used for obtaining the most optimal solution for a problem with given constraints.
- Using linear programming requires defined variables and constraints, to find the largest objective function (maximization).
- In some cases, linear programming is instead used for the smallest possible objective function value (minimization).
- Linear programming requires the creation of inequalities and then graphing those to solve problems.
- Some linear programming can be done manually.
- When the variables and calculations become too complex and require the use of computational software.
Forecasting and Scheduling:
1. Forecasting:
- The main purpose of forecasting is to estimate the occurrence, timing, or magnitude of future events.
- Once, the reliable forecast for the demand is available, good planning of activities is needed to meet the future demand.
- Forecasting thus provides input to the planning and scheduling process.
2. Scheduling:
- Scheduling involves fixing the priorities for different jobs and deciding the starting and finishing time of each job.
- The main purpose of scheduling is to prepare a time-table indicating the time.
- Scheduling is used to allocate resources over time to accomplish specific tasks.
- It should take account of the technical requirement of the task, available capacity, and forecasted demand.
- The output plan should be translated into operations, timing, and schedule on the shop floor.
- Detailed scheduling encompasses the formation of the starting and finishing time of all jobs at each operational facility.
- Gant Chart is used for scheduling after forecasting.
